+
+The asdcplib library is a set of objects that offer
+simplified access to files conforming to the sound and
+picture track file formats developed by the SMPTE Working
+Group DC28.20 (now TC 21DC).
+
+Recently, support has also been added for SMPTE draft ST
+2067-5 "IMF Essence Component", AKA "AS-02". This code was
+donated by Fraunhofer IIS. It carries additional copyright
+information which should be listed whenever you link the
+AS-02 elements of the library. Please look at the top of
+the AS-02 files to see this copyright information.
+
+AS-02 support is carried in separate object modules, so
+unless you #include <AS_02.h> and link libas-02.so you are
+still using plain old asdcp.
+
+This work was originally funded by Digital Cinema Initiatives,
+LLC (DCI). Subsequent efforts have been funded by Deluxe
+Laboratories, Doremi Labs, CineCert LLC, Avica Technology
+and others.
+
+**The asdcplib project was originally housed on SourceForge.
+The project has moved to http://www.cinecert.com/asdcplib/
+
+The project formerly depended upon the mxflib project. Because
+of its focus on covering the whole of the MXF specifications,
+mxflib is considerably larger and more complex that what I
+require for this application. For this reason I have created
+a dedicated MXF implementation that is now part of this
+library. Special thanks to Matt Beard and Oliver Morgan for
+their great work and support.
+
+Thanks also to the members of the SMPTE DC28.20 packaging
+ad-hoc group and the members of the MXF Interop Initiative
+for their encouragement and support. Special thanks to
+Jim Whittlesey and Howard Lukk at DCI for proposing and
+supporting this project.
+
+
+Design Notes
+
+This library is intended (but of course not limited) for
+use by developers of commercial D-Cinema products (and now
+IMF!). It is designed to be easily integrated into a wide
+variety of development environments. Commercial users are
+strongly urged to use static linking (at least where you use
+this library) to prevent malicious in-field replacement of
+critical system modules. This recommendation should be
+considered wherever Open Source or Free software is being
+used in conjunction with critical security parameters, such
+as cryptographic keys.
+
+The author strives mightily to provide an API that is completely
+independent of operating system and other library dependencies,
+and which allows selective replacement of some modules for
+local needs. Specifically, the essence parsers and OpenSSL
+crypto functions can be replaced by linking to alternative
+implementations of the ASDCP:: objects which provide those
+services.
+
+AS_DCP.h contains the entire AS-DCP API. You do not need to
+read any of the other files, except maybe asdcp-test.cpp which
+contains detailed usage examples of each of the API's services.
+The KM_* files may be of interest for general development
+support, but may be ignored if all you want is simple AS-DCP
+support.
+
+Likewise, draft 2067-5 "IMF Essence Component" (AS-02) support
+is entirely contained in AS-02.h
+
+
+Build Instructions
+
+On more-or-less POSIX systems (OS X, Linux, and BSD), GNU make and
+autotools are required to build asdcplib. The same configure script
+will also build this package on Windows machines with Cygwin and
+MinGW installed. For those Windows users who would prefer to build
+this natively, an "nmake" build file and instructions can be found
+in the win32 subdirectory.
+
+OpenSSL is also required, any recent version should be fine. See
+http://www.openssl.org/ for more information and download instructions.
+
+Optional support for writing Timed Text Track Files is supported by
+either Xerces-C or Expat. See http://xerces.apache.org/xerces-c/ or
+http://expat.sourceforge.net/ for source and build instructions.
+
+To configure and build, type './configure' followed by 'make'. There
+are several test targets on the POSIX side, but you need to assemble
+a set of test files to use them. AS-02 support can be enabled with
+ --enable-as-02.
+
+I have tested this build on win32, Linux, OpenBSD, and Darwin
+platforms. Others may work as well.
+
+
+
+
+Utilities
+
+asdcp-test - Writes, reads and verifies AS-DCP (MXF) track files.
+
+asdcp-wrap - Writes AS-DCP (MXF) track files.
+
+asdcp-unwrap - Extracts essence from AS-DCP (MXF) track files.
+
+asdcp-info - Displays information about AS-DCP (MXF) track files.
+
+asdcp-util - Calculates digests and generates random numbers and UUIDs.
+
+as-02-wrap - Writes AS-02 Essence Component files.
+
+as-02-unwrap - Extracts essence from AS-02 Essence Component files.
+
+kmfilegen - Writes and verifies large files using a platform-
+independent format. Use it to test issues related to large files.
+
+kmuuidgen, kmrandgen - generate UUID values and random numbers.
+
+wavesplit - Splits a WAVE file into two or more output files. Used
+ to untangle incorrectly-paired DCDM sound files.
+
+blackwave - Write a WAVE file of zeros.
+
+pinkwave - Write a WAVE file of SMPTE ST 2095 pink noise.
+
+j2c-test - Displays information about JP2K codestreams.
+
+Experimental feature: Prototype for High Dynamic Range is a wrapper
+for the IMF application that allows JPEG-2000 codestreams to be paired
+with opaque blobs of metadata. AS-02 support must be enabled to
+build this feature, so --enable-as-02 must be enabled if
+--enable-phdr is to be used. The following executable programs will be
+built:
+
+phdr-wrap - Writes AS-02 PHDR Essence Component files.
+
+phdr-unwrap - Extracts essence from AS-02 PHDR Essence Component files.
+
+
+Documentation
+
+The API documentation is mostly in AS_DCP.h. and AS_02.h Read those
+files for a detailed description of the library's capabilities. Read
+asdcp-*.cpp and as-02-*.cpp files for library usage examples. The
+command-line utilities all respond to -h.
+
+
+Change History
+
+2019-02-12 - 2.10.32 -- bug fixes
+ o Fixed parsing of as-02-wrap -tfr (ACES) option value
+ o Fixed ISXD bugs:
+ o Incorrect UTF_8_Text_DataEssenceCoding UL
+ o Incorrect ISXDDataEssenceDescriptor_NamespaceURI UL
+ o Incorrect use of FrameWrappedISXDData UL
+ o Incorrect use of FrameWrappedISXDContainer UL
+ o Added wide-char support for filenames on Win32, allows UTF-8 characters in
+ calls to Kumu::File*::Open*(). The macro KM_WIN32_UTF8 must be defined to
+ enable this feature.
+
+
+2018-10-15 - 2.10.31
+ o NOTE: Use of MXFGCGenericEssenceMultipleMappings in AS-02 files is not
+ defined by standards and will soon be withdrawn from this library. If you
+ would like to experience this change now, define the macro
+ ASDCP_GCMULTI_PATCH
+ o Removed PIMD support (unused prototype)
+ o Returned the DataEssenceCoding UL version byte to "5" in Atmos files
+ o Fixed ColorPrimaries_ACES UL version byte
+ o Added "FSKSync" audio channel label to the MCA label generator
+ o SMPTE RDD 45 requires a minimum BER encoding length of five (5) bytes for
+ Content Element packets. The Write_EKLV_Packet() API has been modified to
+ allow the specification of this value. All existing wrapping modules have
+ been changed to conform to the new API, and all continue to use four (4)
+ as the minimum BER encoding length. Write_EKLV_Packet() will continue to
+ generate BER encodings with a length greater than the specified minimum for
+ payloads that are larger than values encoded using the specified minimum.
+
+

+
+
+2016-08-11 - bug fixes, 2.5.15
+
+ o Modified as-02-wrap to pass WhiteRefLev, BlackRefLev and ColorRange
+ (contributed by Elmer Musser / Rod Bogart)
+ o Fixed a bug in the index reader that allowed an out-of-bounds vector index
+ to be used.
+ o Modified the IndexEntry parser to ignore additional bytes belonging to slice
+ values.
+
+
+2016-05-06 - bug fixes, 2.5.14
+
+ o Release 2.5.12 caused two problems with Atoms and DTS-X wrapping that are
+ addressed by this release. The UL values that were changed to correct the
+ DCData (ST 429-14) implementation had two unintended side-effects:
+ 1. v2.5.12 cannot read old DCData (and thus DTS-X) track files
+ 2. v2.5.12 creates broken Atmos track files (incorrect ULs)
+ The fix for this involved the following changes:
+ 1. ASDCP::DCData::(MXFReader|MXFWriter) are no longer base classes of
+ ASDCP::ATMOS::(MXFReader|MXFWriter).
+ 2. New UL values have been added to carry the original Atoms UL values:
+ a. DolbyAtmosDCDataWrappingFrame
+ b. DolbyAtmosDCDataEssence
+ c. DolbyAtmosDCDataDescriptor
+ 3. ASDCP::ATMOS::(MXFReader|MXFWriter) have been modified to use the
+ DolbyAtmosDCData* UL values.
+ 4. ASDCP::DCData::MXFReader will parse files having either DCData* or
+ DolbyAtmosDCData* UL values.
+ 5. ASDCP::DCData:: MXFWriter continues to use DCData* UL values from ST
+ 429-14
+ o Some optional parameters of the MXF metadata packs were being erroneously
+ initialized with a value of zero (0), such as GenericPictureEssenceDescriptor
+ ::SignalStandard, GenericPictureEssenceDescriptor::SampledXOffset(0), etc.
+ o Added higher edit rates (96, 100, 120) to the cinema TimedText_Parser
+
+ o Defined bool ASDCP::UL::operator<(const UL& rhs) const, which is needed to
+ carry out the version-insensitive lookup policy when searching for ULs in a
+ std::map<> of UL entries.
+ o New files: src/info.in src/CMakeLists.txt
+ o Removed filess: AS_DCP_DCData_internal.h
+
+
+2016-03-17 - bug fixes, 2.5.12
+ o Changed default UNIX file permissions to "666"
+ o Changed default UNIX file permissions to "777"
+ o Added missing initializer for caltime::offset

+ o Big patch from Wolfgang Ruppel:
+ o Corrected erroneous fixed-tag values in ActiveHeight, ActiveWidth,
+ ActiveXOffset, ActiveYOffset UL definitions.
+ o Provided a stub implementation for Kumu::DirScannerEx (A real
+ implementation will follow soon.)
+ o Added as-02-info program
+ o Added Seek() method to PCM parsers
+ o Added CMakeLists.txt
+
+
+2015-11-10 - bug fixes, IMF text, pink noise, 2.5.11
+ o I moved personal dev environment from older gcc to newer clang. Many
+ small changes were made to satisfy the new compiler:
+ - Altered many printf format codes to use the correct format for the
+ given integer type.
+ - Parenthesized some expressions to clarify previously ambiguous
+ expectation about precedence.
+ - Created macro KM_MACOSX for use in OS-specific code selection.
+ - Removed last uses of the old C-language abs(), now using Kumu::xabs().
+ - Removed last uses of the old C-language atoi(), not using strtol().
+ o Added platform-independent call Kumu::GetExecutablePath() (to be tested
+ on win32).
+ o Added new capabilities to Result_t.
+ o Added imlementation of SMPTE ST 2092-1 pink noise generator.
+ o Added pinkwave CLI utility.
+ o Added font support to the IMF timed-text wrapper.
+ o Fixed a bug that was causing Array properties to be written without
+ the (count, length) header (from PAL).
+ o General review of Batch/Array distinction throughout the project.
+ o Cleaned up definitions of optional properties in all MXF metadata packs.
+ o Fixed Win32 build (from Crowe).
+ o Fixed a bug that caused incorrect failure when parsing JPEG 2000
+ codestreams having fewer than five decomposition levels. (from Korneder).
+ o Fixed missing UUID generation in some instances of the MCALinkID property.
+ o Added -w option to asdcp-wrap to support use of WTF label with MCA.
+ o Altered asdcp-wrap to recognize "-C <UL>" when MCA is being used.
+ o Fixed broken -A <w>/<h> option in as-02-wrap and phdr-wrap.
+ o asdcp-wrap and as-02-wrap now allow split channel groups in MCA labels.
+
+
+2015-02-23 - bug fixes, 2.4.10
+ o Fixed a new bug introduced by the fix to large numbers of subtitle ancillary
+ resources.
+ o Added support for generic Aux Data (ST 429-14) to asdcp-wrap.
+
+
+2015-02-19 - PHDR feature, bug fixes, 2.4.9
+ o Modified PCMParser and PCMParserList to return partial frame buffers at the
+ end of a WAV input file. This was needed to allow wrapping all samples into
+ an AS-02 audio file (which is clip-wrapped) in the case where the input file
+ has an odd number of samples with respect to the frame buffer size being
+ used. If there is more than one input file the length of the last buffer
+ will be determined by PCMParserList to be the shortest of the input files.
+ Prior to this change, partial samples in an input WAV file have been
+ abandoned (i.e., not written out to the MXF file). As a result, AS-DCP
+ applications will have to decide whether to abandon the partial last frame
+ (usually detected by testing frame_buffer.Size() != frame_buffer.Capacity())
+ or write it to the MXF file. Programs written to the old API will write the
+ partial frame (i.e., new behavior.) This should not be harmful since the
+ remainder of the buffer is zeroed and the output file will contain one
+ additional edit unit compared to the previous version.
+ o asdcp-wrap has been modified to test for the partial buffer and by default
+ will complain and abandon the buffer (i.e., same behavior but with a warning
+ message.) A new command line switch (-g) alters this behavior and writes
+ the buffer to the MXF file (it still warns the user that this condition is
+ present.)
+ o as-02-wrap now wraps all samples from the input file to the MXF file. There
+ is no padding, the clip is exactly the set of samples from the input.
+ o as-02 unwrap is temporarily restricted to creating wav files that are
+ aligned with the frame buffer size. This means that the output file will
+ be longer than the original WAV input in the case where the input file has
+ an odd number of samples with respect to the frame buffer size being used.
+ The pad samples are zero (silence).
+ o Modified CalcFramesFromDurationInSamples() to increment the count by one for
+ the case where the input file has an odd number of samples with respect to
+ the frame buffer size being used (previously it truncated the odd samples.)
+ o Fixed ST 429-5 / ST 2067-5 wrapping to increase header space when ancillary
+ resources are present (fixes a bug that cause the header to overflow the
+ allotted space when large numbers of PNG files were present.)
+ o Refactored GetXMLDocType() to use the XML parser.
+ o Added ParseFirstFromString() method to Kumu::XMLElement
+ o Removed Kumu::StringIsXML from the API.
+ o Added ASDCP::MXF::RGBALayout type
+ o Added J2CLayout property to JPEG2000PictureSubDescriptor
+ o Changed km_token_split() to retain empty elements in the output list
+ o Added PHDR wrapping for AS-02.
+ o Added J2CLayout property to the JPEG2000PictureSubDescriptor. This
+ support is preliminary: the Raw data type is being used instead of
+ RGBALayout type, which will be in the next release.
+
+
+2014-10-2 - Bug fixes and enhancements, 2.2.6

+ with GenericPictureEssenceDescriptor objects.
+ o Fixed a bug that was suppressing PictureComponentSizing,
+ CodingStyleDefault and QuantizationDefault when writing the

+ o fixed a bug that caused blackwave to only produce 96kHz WAV files.
+ (thanks to Stephane W)
+
+
+2013-07-02 – IMF/AS-02 support, bug fixes 2.0.0
+ o Massive refactoring of internals to allow easier implementation
+ of AS-02. Some API changes were made as well (note that
+ OPAtomHeader is now OP1aHeader and RIP is no longer part of the
+ OP1aHeader.) If you are using this project as a library (and
+ especially if you are keeping patches against it) PLEASE TAKE
+ TIME TO EVALUATE THIS RELEASE THOUROUGHLY BEFORE ADDING IT TO
+ YOUR RELEASE PATH.
+ o Final integration of Fraunhoffer IIS code contribution. AS-02
+ files are now fully supported with some TODOs and two major
+ exceptions: LEAD indexes are not supported by the MXF writers
+ and interlace images are not yet supported.
+ o Added support for MCA labels (ST 428-12) to asdcp-wrap. Note
+ that this project is still in the early stages of interop testing
+ so errors are likely present and don't expect any server to
+ make use of this feature.

+ o Fixed premature-release bug in the Expat version of the XML parser.
+ Thanks to Carsten Feldheim (IIS) for the tip.
+ o Fixed -W option in asdcp-unwrap. Thanks to RGB.
+ o Added P-HFR support to asdcp-wrap (see URL for details:
+ http://isdcf.com/papers/ISDCF-HighFrameRate-DCP.pdf).
+ o Added support for SMPTE ST 428-21 "Archival Frame Rates".
+ o Added -P option to asdcp-wrap (inserts arbitrary UL into the
+ PictureEssenceCoding property when wrapping JP2K files.)
+ o Added support for 96 kHz files to blackwave.
+ o Added new path and string manglers to Kumu.
+ o Updated MCA ULs (I warned you...). Again please take some
+ time to proof this work against ST 477-4 including the latest
+ drafts of the registries.
+ Changed the version byte (8 0f 16) to 0x0e:
+ MCALabelSubDescriptor
+ AudioChannelLabelSubDescriptor
+ SoundfieldGroupLabelSubDescriptor
+ GroupOfSoundfieldGroupsLabelSubDescriptor
+ GroupOfSoundfieldGroupsLinkID
+ Changed bytes 8 and and 13 of SoundfieldGroupLinkID
+ Added items to the UL dictionary:
+ MCAPartitionKind
+ MCAPartitionNumber
+ MCATitle
+ MCATitleVersion
+ MCATitleSubVersion
+ MCAEpisode
+ MCAAudioContentKind
+ MCAAudioElementKind
+
+
+2012-08-07 - bug fix, 1.10.46
+ o Added missing zero-initializers to time values when parsing a
+ timestamp string (in the case where the optional [Thh:mm.[:ss]]
+ syntax is not present in an encoded string).
+
+2012-03-06 - bug fixes, enhancements 1.9.45
+ o Removed ASDCP::Timestamp, all items that were of that class are now
+ of class Kumu::Timestamp
+ o Refactored Kumu::Timestamp to use KM_tai for internal representation
+ (replaced public Y M D, h, m, s variables)
+ o Refactored Kumu::Timestamp to use KM_tai for WIN32 builds
+ o Added UTC offset awareness to Kumu::Timestamp
+ o Replaced "long GetSecondsSinceEpoch(void) const" with
+ "ui64_t GetCTime() const"
+ o Corrected UL version segment in "7.1 DS" and "WTF" audio format
+ labels (corresponds with publication of ST 429-2:2011).
+ o Exposed MXF object interface (MXF.h, Metadata.h) via ASDCP MXFReader
+ and MXFWriter classes.
+ o Added UL values from ST 377-4:2012. >>>>NOTE: These are preliminary
+ values, subject to change upon final publication of not only ST 377-4
+ but also the relevant registries. This is a good time to compare them
+ to the standard and complain if you think they are wrong!
+ o Added MCALabelSubDescriptor, AudioChannelLabelSubDescriptor,
+ SoundfieldGroupLabelSubDescriptor, and
+ GroupOfSoundfieldGroupsLabelSubDescriptor (from ST 377-4:2012) to
+ Metadata.h
+ o Changed some internals to make MXFWriter::OPAtomHeader() work correctly.
+ o Split asdcp-test into several different programs to help relieve
+ the impenetrable-list-of-arguments problem. asdcp-wrap, asdcp-unwrap
+ and asdcp-info take the place of asdcp-test's -c, -x and -i options,
+ respectively. asdcp-util contains the remaining functions. Note that
+ asdcp-test is now DEPRECATED, new functionality and bug fixes will be
+ aimed at the new tools. Also note that some options and calling
+ conventions are different for the new tools as compared to asdcp-test.
+ Please read the synopses and make sure you understand the new idioms.
+ o asdcp-wrap has a new argument, -C <UL>, that writes the given UL to the
+ ChannelAssignment item in the WaveAudioDescriptor (only useful when
+ writing PCM essence).
+
+
+2011-11-30 - bug fixes v1.8.44
+ o Corrected a wrong decryption UL selection when unwrapping MXF.
+
+
+2011-10-27 - bug fixes v1.8.43
+ o Corrected broken Essence UL matching. (Thanks to Michael Loder).
+
+
+2011-08-31 - bug fixes v1.8.42
+ o Added missing HFR support for PCM essence reader/writer.
+
+
+2011-08-30 - bug fixes, enhancements v1.8.41
+ o UL version byte now ignored when comparing UL values.
+ o Changed the version byte in the TimedTextEssence UL to 0x01. There
+ is no published Essence Keys registry so it can't have a maintained
+ version number.
+ o JP2K Sequence Parser modified to skip directory entries that
+ are not files in the case where the parser is initialized with
+ a directory path. When initialized with a list of file names
+ this check is not performed. Based on a hint by Steve Quartly.
+ o Increased the size of the MPEG header parser buffer.
+ o Added missing FrameType() implementation to ASDCP::MPEG2::MXFReader.
+ o Added missing Close() implementations to MXF reader classes.
+ o Added missing Timestamp::Timestamp(const char* datestr) implementation.
+ (Thanks to Matt Sheby for this and the previous three items.)
+ o Fixed error in Kumu::FortunaRNG::FillRandom() that was returning the
+ end of the random buffer instead of the front (Thanks to Mike Radford).
+ o Added support for proposed sound channel format identifiers
+ '7.1DS' and 'WTF'. Optimistically chose version '0x0c'.
+ o Added support for stereoscopic images in JP2K files at edit
+ rates of 48, 50 and 60 eups (96, 100 and 120 fps).
+
+
+2010.11.15 - bug fixes, enhancements v1.7.40
+ o Fixed bug in long KLV packet support (Thanks to Jim Radford).
+ o Fixed AvgBps in PCM files, *again*. Sorry for the crazy.
+ o More fixes and changes in support of 25, 30, 50, 60 fps.
+ (Thanks to Hans K. for the TC rate bug).
+ o Updated KLVFill UL version element to 0x02.
+ o Type change to support Xerces-C 3.x. (Thanks to Matt Sheby).
+ o Some internal API changes to KLV types. Does not affect
+ operation.
+ o Added NetworkLocator type to MXF metadata types.
+ o Added file offset display to klvwalk.
+
+
+2010.09.09 - bug fixes, enhancements, v1.7.39
+ o Fixed bug in JP2K PictureDescriptor initialization in
+ JP2K::MXFReader::OpenRead() and JP2K::MXFSReader::OpenRead()
+ o Once again fiddling with AvgBbs. How can something so simple
+ be such a constant cause of trouble? Tested with 1-, 2- and
+ 6-channel input Wav files.
+ o asdcp-test now accepts a directory name when making PCM
+ files (-c). The directory name should be the only filename
+ argument. All files in the directory must be Wav files
+ (mixed channel sizes OK). Files are sorted alphabetically by
+ filename. Hint: use numeric name infix to define order:
+ my_movie_00_L.wav
+ my_movie_01_R.wav
+ my_movie_02_C.wav
+ my_movie_03_LFE.wav
+ my_movie_04_LS.wav
+ my_movie_05_RS.wav
+
+
+2010.07.20 - bug fixes, v1.6.37
+ o Fixed TimedTextResourceSubDescriptor UL value.
+
+
+2010.06.16 - bug fixes, v1.6.36
+ o Added support for new Edit Rates to asdcp-test.cpp.
+ o Expanded timed-text file reader in asdcp-test.cpp.
+ o Fixed large BER value encoding (plaintext) and decoding
+ (plaintext and ciphertext). This feature was introduced in
+ v1.5.31).
+ o Fixed AvgBps value for multi-channel Wave input.
+
+
+2010.05.13 - bug fixes, enhancements, v1.6.34
+ o ST 429-5 files have corrected ULs for DCTimedTextDescriptor and
+ GenericStream DataElement. Files made with previous versions of
+ the library are incompatible with this and future versions.
+ o Fixed File Package TrackNumber values. Th
+anks to Sankar.
+ o Added edit rate constants to AS_DCP.h (25, 30, 50, 60).
+ o Changed AudioDescriptor "SampleRate" element name to "EditRate"
+ to make it consistent with the other types.
+ o Now builds with XercesC 3.x.
+ o KM_memio.h has better const behavior.
+ o Fixed a bug in KM_memio.h string archiving.
+
+
+2010.01.05 - bug fixes, enhancements, v1.5.32
+ o Re-fixed swapped Interop and SMPTE OP Atom UL values. The swap
+ introduced in v1.5.31 was done in error.
+ o Added -z,-Z options to asdcp-test (j2c parameter checking)
+ o Reformed jp2k-test as j2c-test, added help and list processing,
+ added to standard install target.
+
+
+2009.12.31 - bug fixes, enhancements, v1.5.31
+ o Fixed swapped Interop and SMPTE OP Atom UL values.
+ o Added get_BER_length_for_value() subroutine.
+ o Modified ASDCP::h__Writer::WriteEKLVPacket() to allow larger BER
+ lengths for KLV packets larger than 16 MB. This was required to
+ support large font files in the SMPTE 429-5 implementation.
+
+
+2009.11.06 - bug fixes, enhancements, v1.5.29
+ o Fixed a bug that could cause HMAC values to be incorrectly
+ stored in MXF files. Files created with versions of asdcplib
+ prior to this version may have incorrect HMAC values.
+ o Improved handing of XML files for MXF wrapping.
+ o Jpeg2000 codestream EditRate and SampleRate mismatches
+ now warns instead of returning an error.
+ o Improved error handling in Jpeg2000 sequence parsing routines.
+ o Added two methods to Kumu::Timestamp, AddSeconds(), to add (or
+ subtract) seconds to a time value, and GetSecondsSinceEpoch()
+ to get the number of seconds since the unix epoch.
+ o Added new option to asdcp-test, '-a', to specify a UUID when
+ creating MXF files.
+ o Added support for specifying the intrinsic duration of MXF files
+ containing timed text.
+ o Added new option to wavesplit, '-i', to display WAV file metadata.
+
+
+2009.05.21 - bug fixes, v.1.4.24
+ o Fixed a bug that caused incorrect SubDescriptors UL values to be
+ written into interop format MXF track files. Note that this involved
+ a substantial reorganization of MXF internals. Please test thoroughly
+ in your application before using in production. Note that this is a
+ significant bug fix and track files created with 1.4.22 may be incompatible
+ with other systems.
+
+
+2009.04.09 - SMPTE format fixes, enhancements and bug fixes, v.1.4.22
+ o asdcplib now uses GNU autotools on POSIX systems to configure
+ and build. See "./configure" for details. Note that two options,
+ --enable-freedist and --with-python are not enabled in the free
+ version of asdcplib and should not be used.
+ o Added build option (CONFIG_RANDOM_UUID) to enable mixed case UUID
+ generation when environment variable KM_USE_RANDOM_UUID is defined.
+ o Fixed a condition that could cause an error to occur when wrapping
+ SMPTE format timed text track files that do not define a starting
+ frame.
+ o Updated ULs for SMPTE format track files.
+ o SampleRate added to JP2K metadata
+ o Support for wrapping 96kHz WAV files added.
+ o Updated ULs for audio channel formats (ChannelFormat)
+ o Updated font subdescriptor MIME Types for TimedText Trackfiles.
+ o Changed time implementation to support dates beyond Jan 19th, 2038.
+ o Xerces-C XML parser support added.
+ o New build method for Windows (see win32/README.txt for details).
+ o Added new functionality in Kumu to recursively create and delete files
+ and directories, and get free disk space for a given volume path.
+ o Added a method to Kumu::Timestamp, AddMinutes(), to add (or subtract)
+ minutes to a time value.
+ o Improved how Kumu::Timestamp parses timestamps with offsets.
+ o Fixed a bug that caused incorrect HMAC values to be calculated.
+
+
+2008.02.16 - SMPTE format fixes, bug fixes v.1.3.18
+ o Added correct SMPTE UL for StereoscopicPictureSubDescriptor.
+ o Exposed JP2K metadata parser as ParseMetadataIntoDesc().
+ o Added simple stereoscopic framebuffer to support paired ReadFrame()
+ and WriteFrame() methods (allows simpler integration with other
+ single-buffer code).
+ o Improved detection of JPEG Interop stereoscopic files.
+ o Win32 build fixes (Thanks to Mike Crowe at DTS).
+ o Added the WITH_MD macro to the makefile. Set this value to one
+ to build Win32 with /MD[d] instead of /MT[d].
+ o The Generic Container UL has been added to the EssenceContainers
+ set in the header partition pack for encrypted files. It has always
+ been there in plaintext files.
+ - Below this point the changes are internal and should not affect you
+ unless you use Kumu directly.
+ o Major refactoring of KM_log.[h|cpp].
+ o Fixed buffer re-sizing issue in Kumu::ByteString.
+ o Replaced type IdentifierList with ArchivableList.
+ o Added COPYING file to the release bundle.
+
+
+2007.12.13 - Bug fixes v.1.2.17
+ o Changed Result_t implementation to use int instead of long, which
+ was causing trouble on some 64 bit platforms.
+ o Fixed EKLV HMAC. NOTE: Breaks backward compatibility with older
+ Interop files. To validate these files, use asdcplib-1.1.14. This
+ should not cause too much trouble since files with broken and
+ non-broken HMAC have been in the wild for years without issue.
+ o Fixed HMAC sequence numbering in encrypted stereoscopic files.
+ o Finished stereoscopic test targets in the makefile.
+ o Fixed the win32 build, now expects VS2005 compiler by default,
+ use WITH_VC6=1 top get VC6 flags.
+ o Stereoscopic and Timed Text modes now have SMPTE UL values.
+ NOTE: SMPTE 429-5 and 429-10 are not yet published. It is possible
+ that these UL values may change before publication. Please use
+ caution when using these features for production work.
+ o Changed a bunch of symbol names in the 429-5 implementation to
+ better match the spec.
+ o Added -U option to asdcp-test to dump the UL library to stdout.
+ o Fixed erroneous placement of the PictureEssenceCoding UL in JP2K
+ files (Interop and SMPTE modes).
+
+
+2007.10.22 - Timed Text, Stereoscopic Picture and Bug fixes v.1.2.16
+ o Significant API changes have been made. Please read all entries
+ in this changelog to be sure you understand the changes. Also
+ note that some changes have been made to LS_MXF_SMPTE files that
+ are incompatible with earlier releases (e.g., EKLV HMAC). If
+ you are looking for a stable interop release, use v.1.1.14.
+ o Fixed RFC 2104 HMAC implementation for LS_MXF_SMPTE only. The
+ broken implementation has been maintained for Interop mode.
+ o Added support for draft SMPTE 429-5 Timed Text Track File. This
+ is still waiting for official SMPTE ULs, so do not use it for
+ shipping products. An XML parser is needed to create a Timed
+ Text Track File; Expat is now an optional part of the build.
+ Make with WITH_XML_PARSER=1 to link with Expat. If you do not
+ link with expat, you will get an error when using the TimedText::
+ DCSubtitleParser class. See also S429-5-cgi.cpp for an example
+ that shows how to serve plaintext MXF file elements directly via
+ HTTP.
+ o Added support for draft SMPTE 429-10 Stereoscopic Picture Track
+ File, including the JPEG Interop version. This is still waiting
+ for official SMPTE ULs, so do not use it with LS_MXF_SMPTE for
+ shipping products.
+ o Refactored the following files as a side-effect of the above
+ work: AS_DCP_JP2K.cpp AS_DCP_MPEG2.cpp AS_DCP_PCM.cpp
+ AS_DCP_MXF.cpp AS_DCP_internal.h MXF.[h|cpp] MXFTypes.[h|cpp]
+ Metadata.[h|cpp] h__Reader.cpp h__Writer.cpp klvwalk.cpp.
+ WARNING: While significant effort has been extended to make sure
+ that these changes do not affect existing stable file support,
+ users are cautioned to test this release thouroughly.
+ o Added a large set of filesystem path manglers to KM_fileio.h. See
+ path-test.cpp for example usage. The path manglers have not yet
+ been tested on win32 platforms (they are currently used only by
+ the Timed Text module.
+ o The PathIsFile(), PathIsDirectory() and FileSize() subroutines
+ have been modified to accept const std::string& instead of
+ const char*.
+ o Added namespace and parsing support (Expat) to Kumu::XMLElement
+ (currently used only for Timed Text support). Also added some
+ new accessors.
+ o Altered MXF::UTF16String to use mbtowc() and wctomb().
+
+
+2007.03.31 - Bug fixes v.1.1.14
+ o Fixed KeyFrameOffset value in MPEG wrapping to have negative
+ value. This is probably not yet complete for handling all
+ types of GOPs. Please send chunks of MPEG-2 VES that you
+ find which break this. Thanks to Doremi.
+ ** no other file format changes in this release **
+ o Fixed error in RIP interpretation when reading arbitrary (i.e.,
+ non-MXF) files.
+ o Fixed a memory leak in ASDCP::MXF::OPAtomHeader when used
+ in read mode. Thanks to Mahesh Bajaj for pointing out this
+ bug and the one above.
+ o Removed asserts from KM_fileio, replaced with RESULT_WRITEFAIL
+ return value statements.
+ o Added -s and -p to the makefile install target.
+ o Altered ByteString behavior to use target Length() in copy
+ operations (instead of Capacity()).
+ o Added new Set() method to ByteString.
+ o Fixed a bug in ByteString::Unarchive() that caused the operation
+ to fail when the buffer was smaller than the read (i.e., when
+ Capacity() was called).
+ o Added IdentifierList class to KM_util.h.
+ o Changed some Error() messages to Debug() in Wav.cpp
+ o Revived jp2k-test.cpp and asdcp-mem-test.cpp (they both had
+ stale #includes).
+
+
+2007.02.15 - Bug fixes v1.1.13
+ o Removed 'VDescObj->SampleRate.Numerator = VDesc.FrameRate;'
+ from MPEG2_VDesc_to_MD() in AS_DCP_MPEG2.cpp, was line 76.
+ o Added KM_TEST_NULL_STR_L() and KM_TEST_NULL_L() macros to
+ KM_log.h. These versions log the location of the null value.
+ Macros are now used in any module that includes KM_log.h.
+ o MPEG2 VES with run of zero values at the head is now OK.
+ o Increased VESHeaderBufSize to 16K.
+ o Added makefile support for local OpenSSL in ../openssl, if
+ present.
+ o The Kumu::PathIs*() functions now return false if a null or
+ empty string is given (used to be an assert).
+ o Cleaned up the install target in the makefile.
+ o Fixed SMPTE 429-6 HMAC -- FIPS 186-2 implementation was
+ laughably incorrect. Thanks to Doremi for pointing this out.
+ o Removed default parameter to HMACContext::InitKey().
+ o Cleaned up messages and CLI arg handling in asdcp-test.
+
+
+2006.11.19 - Mo better stuff v1.1.12
+ o Changed read-only Result_t accessor methods to const.
+ o Added Base64 (-B) option to kmrandgen.
+ o Removed 16-bit alignment restriction from kmrandgen.
+ o Improved WAV file extraction speed (Thanks to Jim Radford
+ for pointing this out).
+ o Added single-channel split for WAV extraction (asdcp-test -1).
+ o Fixed remainder bug in h__RNG::fill_rand().
+
+
+2006.11.03 - Bug fixes v1.1.11
+ o Increased index table entry list size to 5000.
+ o Added length checking to TLV writer (returns error if TLV
+ payload exceeds 64kB).
+ o Fixed partition header and RIP errors related to 2-partition
+ files (MXF Interop mode).
+ o Added -t option to asdcp-test (SHA-1 digest with Base64 output
+ on stdout).
+ o Fixed Sub Descriptor reference bug (Thanks to Denis Leconte
+ for dogged determination).
+ o Added directory-of-wav detection to RawEssenceType()
+ o Modified MXF::Partition::AddChildObject() to only generate
+ a UUID if the InstanceID is unset.
+ o Added ComponentMaxRef & ComponentMinRef to RGBAEssenceDescriptor.
+ More to follow.
+ o Added detection of 2K/4K jp2c, writing correct 4K metadata.
+
+
+2006.10.05 - Bug fixes v1.1.10
+ o Changed RM_RELEASE to RL_RELEASE in MXFTypes.h.
+ o Changed the MXF writer to use RL_RELEASE (was RL_DEVELOPMENT).
+ o Really fixed source reference chain.
+ o Updated JP2K file package label.
+ o Changed location of JPEG2000PictureSubDescriptor in the
+ header (was erroneously before Preface).
+ o Altered LS_MXF_INTEROP to produce 2-partition files.
+
+
+2006.09.25 - Bug fixes v1.1.9
+ o Fixed SourcePackageID value. All files will be 'original',
+ i.e. SourcePackageID will be all zeros. Let me know if you
+ want to set SourcePackageID.
+ o Fixed compiler warnings on some Linux platforms
+ o Fixed the build so that BUILD_DIR is no longer created
+ as a dependency.
+ o Added duration detection to the raw essence parsers. The
+ MPEG parser uses a nasty approximation so don't use it
+ without paying close attention to the result.
+ o Modified PCMParserList to make it more useful as a base
+ class.
+ o Fixed bugs and re-organized command-line help in asdcp-test
+ and klvwalk.
+ o Fixed two-partition file reads.
+ o Fixed Win32 PRNG initialization.
+ o Renamed asdcp-lf-test as kmfilegen.
+ o Added kmrandgen and kmuuidgen.
+ o Added string retrieval mechanism to Result_t.
+ o Refactored Kumu::Identifier and its sub-classes.
+ o Altered Kumu::PathIsFile to return true when the path
+ is a symbolic link (unix only).
+ o Altered Kumu::FileWriter::OpenWrite to use file creation
+ mode 0664 (was 0644) (unix only).
+ o Added Kumu::WriteStringIntoFile() subroutine.
+
+
+2006.04.05 - Bug fixes and new stuff v1.1.7
+ o Fixed a bug in the MPEG parser that caused it to fail when
+ handling start codes spanning buffer boundaries
+ o Added wavesplit and blackwave utility programs
+ o Added support for revised SMPTE HMAC key derivation when
+ using LS_MXF_SMPTE
+ o Refactored platform compatibility and general utilities
+ into a new sub-library "Kumu". There are no new build
+ steps or dependencies, but some important things have
+ changed:
+ + Result_t is no longer an enum, it is now a class.
+ Library result codes are now declared as const objects
+ like this:
+
+ const Kumu::Result_t RESULT_FORMAT (-101, "The file...");
+
+ The macros ASDCP_SUCCESS and ASDCP_FAILURE still work
+ the same way thanks to an operator overload for type long.
+ See KM_error.h for more information.
+ + The logging interface has been moved out of AS_DCP.h
+ and into KM_log.h
+ o Some of the command line utilities that were using headers
+ other than AS_DCP.h have been changed to use the Kumu
+ equivalents. If you have code based on those utilities, you
+ will have to update by hand.
+ o Added new types to the EssenceType_t enum.
+ o The guard macro for Win32 code has changed from WIN32 to
+ KM_WIN32.
+
+
+2006.03.2x - new stuff
+ o Proper handling of stream-id byte of essence UL values
+ o writes 3-partition files, reads 2-part or 3-part
+
+
+2006.03.16 - bug fixes plus
+ o Removed SMPTE_LABELS compile-time option. The reader will now
+ silently accept either SMPTE or MXF Interop labels, the writer
+ can be instructed which to use at runtime. Default is Interop.
+ o Added an AIFF reader. Support is preliminary, it works with the
+ AIFF files I have on hand.
+ o More code refactoring. More to come.
+
+
+2006.03.09 - full read-write
+ o Removed ASDCP_WITHOUT_OPENSSL compile-time option.
+ o Full read/write now working on new MXF library
+
+
+2005.00.00 - A New Hope
+ o The temporary mxf-lite has been removed. MXF files are now
+ managed via the objects in KLV.h, MXFTypes.h MXF.h and
+ Metadata.h. This release does not support writing MXF files.
+ o Fixed a header interpretation error in the Wav parser.
+
+
+2005.00.00 - The Reformation
+ o Removed mxflib as a dependency by forking the necessary
+ functions and placing them in the mxf-lite subdirectory.
+ Please note that the very heavy modifications done here
+ render all comparisson to mxflib code a substantial task.
+ All errors are now mine and users are warned not to bug
+ Oliver or Matt for help with this code. The version of
+ mxflib at the time of the fork was: 0.5.1.3.
+
+
+2005.06.03 - bug fixes v0.10.18
+ o Updated UL batch to include GC UL.
+
+
+2005.05.27 - bug fixes v0.10.17
+ o Un-did essence container and compression descriptor changes.
+ The default build reflects MXF Interop decisions as of 26 May.
+ o Added note about build versions to README (see above).
+ o Added warnings to SMPTE_LABELS builds.
+ o Fixed JP2K essence container label.
+
+
+2005.05.02 - bug fixes v0.10.16
+ o Reorganized internal files, added file reader object, added OS
+ portability header, removed and renamed some files. If you have a
+ patch against previous versions of the source, you should check
+ it thoroughly.
+ o Added RGBA attributes to JP2K descriptor.
+ o Changed interface to CodestreamParser.
+ o Added JP2K parser implementation. It is parsing each frame but is
+ not yet being used to populate the descriptor.
+ o Added 48fps option for `asdcp-test -p`.
+ o Added picture rate constants to AS_DCP.h (23.976, 24, 48).
+ o Added sample rate constant to AS_DCP.h (48k).
+ o Changed asdcp-test to encrypt picture headers by default
+ (plaintext offset will be 0), added -E option to allow
+ plaintext headers.
+
+
+2005.04.28 - bug fixes v0.9.15
+ o The XML descriptors for the crypto DMS have moved in mxflib to
+ the file DMS_Crypto.xml (they were in DMS_DCPENC.xml). Older
+ installations should update the file from mxflib.
+ o Added Close() and Seek() to ~MyFileWriter(), cleaned up headers
+ o Added UUID generator output mode (-u).
+ o Added -S option to extract PCM essence into stereo wav files
+ o Added more UL testing and conformance checking.
+ o Added macro SMPTE_LABELS which causes the library to be built
+ with SMPTE (as opposed to MXF Interop) labels. This is not
+ set by default, and currently only affects the PCM container
+ label and encrypted element label.
+ o Cleaned up the GNUmakefile test targets, the source files
+ are now named with the TEST_FILE_PREFIX macro.
+ o enabled 23.976-framed PCM (2002 samples per frame)
+ o The size of the asdcp-test frame buffer for picture essence
+ may now be set from the command line (-b). The default is 4MB.
+ o h__Reader::ReadEKLVPacket() now tests the UL (duh) and switches
+ on the value, allowing plaintext and ciphertext frames to
+ be mixed in the file.
+ o Fixed error in UUID generator format.
+ o JP2K files now use the GenericPictureDescriptor to store
+ ContainerDuration and SampleRate. SampleRate is mapped
+ to EditRate in the PictureDescriptor struct. This fixes
+ the second caveat from the 0.8.13 release.
+ o Fxed bug in PCMParserList that was miscalculating the extent
+ of a PCM sample. This bug did not affect API users, it was
+ only present in asdcp-test.
+ o Fixed EditRate on PCM files (was showing sample rate)
+ o Fixed Encrypted Essence Container UL
+ o Fixed BlockAlign value for PCM essence
+
+ - The following changes were provided by Jeff Loewenguth
+ - Thanks Jeff!
+ o Moved the DMS CryptographicFramework entry from the material
+ package to the source package
+ o Fixed erroneous Source Essence Container Label value
+ o Fixed broken sort of JP2K frames in JP2K parser
+ o Added FindFrameGOPStart() method to the MPEG2 MXFReader

+
+
+2004.12.30 - bug fixes + wav files v0.8.14
+ o Added WAV file write to asdcp-test (uses mxflib::waveheader_t).
+ o Three-partition files reading properly. adscplib still writes
+ two-partition files.
+ o Changes in the mxflib WAV essence parser API had broken
+ asdcplib's ability to read essence from a WAV file. I have
+ fixed this bug, but at the expense of breaking compatibility
+ with older versions of mxflib. Beware!
+ o Removed redundant (but working) bin-text-bin conversions.
+
+
+2004.12.23 - JPEG 2000 support v0.8.13
+ o Reads/writes JPEG 2000 essence in plaintext and ciphertext
+ with the following caveats:
+ - The Picture Essence Descriptor is empty.
+ - Because there is no essence descriptor, the reader code
+ in asdcp-test has no idea how many frames are in the file
+ and ends with an out-of-bounds frame error. This error
+ is being suppressed in asdcp-test for the current release.
+ o Still broken when reading three-partition files.
+
+
+2004.10.22 - fixes and UL updates v0.7.11
+ WARNING: COMPATIBILITY BREAKPOINT

+
+2004.07.02 - full plaintext + ciphertext read/write v0.6.9
+ o HMAC, plaintext offest and raw ciphertext read supported
+ o back to proper CBR index
+ o MPEG temporal offset working
+
+
+2004.07.01 - plaintext + ciphertext read/write v0.5.8
+ o encryption of MPEG and PCM essence supported with the
+ following caveats:
+ - no HMAC support
+ - no plaintext offest support
+ - no raw ciphertext read support
+ o moved to reflecting the whole KLV triplet in the CBR
+ index (now incompatible with mxflib, still searching
+ for info about what's "right")
+ o awaitng the following fixes/features:
+ - retrieve Temporal Offset from index in MPEG2::Reader
+ - test for correct ULs when reading frame triplets
+ - fix header metadata items for encrypted files

+ o tested under win32 and linux. FreeBSD and Darwin do not work
+
+
+2004.02.04 - First release (v0.1.1):

+ access to the read and info capabilities of the library.
+ o The MPEG2 reader is functional but not fully tested.
+ o Some file format integrity tests remain to be coded.
+ o The PCM reader is mostly complete, I am having difficulty
+ getting a suitable test file from mxfwrap.

+ above the mxflib/klvlib level. Let me know if it is important
+ to you.
+ o The files xmldict.xml and types.xml must be in the current
+ directory when the program is run. The files are supplied
+ with mxflib. Runtime location of the files is not currently
+ a project goal. Comments on how best to handle this situation
+ would be appreciated. See AS_DCP.cpp at init_mxf_types()
+ for a more detailed discussion.

-$Id$
-
-The asdcplib library is a set of objects that offer
-simplified access to files conforming to the sound and
-picture track file formats developed by the SMPTE Working
-Group DC28.20 (now TC 21DC).
-
-Recently, support has also been added for SMPTE draft ST
-2067-5 "IMF Essence Component", AKA "AS-02". This code was
-donated by Fraunhofer IIS. It carries additional copyright
-information which should be listed whenever you link the
-AS-02 elements of the library. Please look at the top of
-the AS-02 files to see this copyright information.
-
-AS-02 support is carried in separate object modules, so
-unless you #include <AS_02.h> and link libas-02.so you are
-still using plain old asdcp.
-
-This work was originally funded by Digital Cinema Initiatives,
-LLC (DCI). Subsequent efforts have been funded by Deluxe
-Laboratories, Doremi Labs, CineCert LLC, Avica Technology
-and others.
-
-**The asdcplib project was originally housed on SourceForge.
-The project has moved to http://www.cinecert.com/asdcplib/
-
-The project formerly depended upon the mxflib project. Because
-of its focus on covering the whole of the MXF specifications,
-mxflib is considerably larger and more complex that what I
-require for this application. For this reason I have created
-a dedicated MXF implementation that is now part of this
-library. Special thanks to Matt Beard and Oliver Morgan for
-their great work and support.
-
-Thanks also to the members of the SMPTE DC28.20 packaging
-ad-hoc group and the members of the MXF Interop Initiative
-for their encouragement and support. Special thanks to
-Jim Whittlesey and Howard Lukk at DCI for proposing and
-supporting this project.
-
-
-Design Notes
-
-This library is intended (but of course not limited) for
-use by developers of commercial D-Cinema products (and now
-IMF!). It is designed to be easily integrated into a wide
-variety of development environments. Commercial users are
-strongly urged to use static linking (at least where you use
-this library) to prevent malicious in-field replacement of
-critical system modules. This recommendation should be
-considered wherever Open Source or Free software is being
-used in conjunction with critical security parameters, such
-as cryptographic keys.
-
-The author strives mightily to provide an API that is completely
-independent of operating system and other library dependencies,
-and which allows selective replacement of some modules for
-local needs. Specifically, the essence parsers and OpenSSL
-crypto functions can be replaced by linking to alternative
-implementations of the ASDCP:: objects which provide those
-services.
-
-AS_DCP.h contains the entire AS-DCP API. You do not need to
-read any of the other files, except maybe asdcp-test.cpp which
-contains detailed usage examples of each of the API's services.
-The KM_* files may be of interest for general development
-support, but may be ignored if all you want is simple AS-DCP
-support.
-
-Likewise, draft 2067-5 "IMF Essence Component" (AS-02) support
-is entirely contained in AS-02.h
-
-
-Build Instructions
-
-On more-or-less POSIX systems (OS X, Linux, and BSD), GNU make and
-autotools are required to build asdcplib. The same configure script
-will also build this package on Windows machines with Cygwin and
-MinGW installed. For those Windows users who would prefer to build
-this natively, an "nmake" build file and instructions can be found
-in the win32 subdirectory.
-
-OpenSSL is also required, any recent version should be fine. See
-http://www.openssl.org/ for more information and download instructions.
-
-Optional support for writing Timed Text Track Files is supported by
-either Xerces-C or Expat. See http://xerces.apache.org/xerces-c/ or
-http://expat.sourceforge.net/ for source and build instructions.
-
-To configure and build, type './configure' followed by 'make'. There
-are several test targets on the POSIX side, but you need to assemble
-a set of test files to use them. AS-02 support can be enabled with
- --enable-as-02.
-
-I have tested this build on win32, Linux, OpenBSD, and Darwin
-platforms. Others may work as well.
-

-
-
-Documentation
-
-The API documentation is mostly in AS_DCP.h. and AS_02.h Read those
-files for a detailed description of the library's capabilities. Read
-asdcp-*.cpp and as-02-*.cpp files for library usage examples. The
-command-line utilities all respond to -h.

-
-Change History
-
-2019-02-12 - 2.10.32 -- bug fixes
- o Fixed parsing of as-02-wrap -tfr (ACES) option value

- o Incorrect use of FrameWrappedISXDData UL
- o Incorrect use of FrameWrappedISXDContainer UL
- o Added wide-char support for filenames on Win32, allows UTF-8 characters in
- calls to Kumu::File*::Open*(). The macro KM_WIN32_UTF8 must be defined to
- enable this feature.
-
-
-2018-10-15 - 2.10.31
- o NOTE: Use of MXFGCGenericEssenceMultipleMappings in AS-02 files is not
- defined by standards and will soon be withdrawn from this library. If you
- would like to experience this change now, define the macro
- ASDCP_GCMULTI_PATCH
- o Removed PIMD support (unused prototype)
- o Returned the DataEssenceCoding UL version byte to "5" in Atmos files
- o Fixed ColorPrimaries_ACES UL version byte
- o Added "FSKSync" audio channel label to the MCA label generator

- allow the specification of this value. All existing wrapping modules have
- been changed to conform to the new API, and all continue to use four (4)
- as the minimum BER encoding length. Write_EKLV_Packet() will continue to
- generate BER encodings with a length greater than the specified minimum for
- payloads that are larger than values encoded using the specified minimum.

- (contributed by Elmer Musser / Rod Bogart)
- o Fixed a bug in the index reader that allowed an out-of-bounds vector index
- to be used.

- values.
-
-
-2016-05-06 - bug fixes, 2.5.14
-
- o Release 2.5.12 caused two problems with Atoms and DTS-X wrapping that are
- addressed by this release. The UL values that were changed to correct the
- DCData (ST 429-14) implementation had two unintended side-effects:
- 1. v2.5.12 cannot read old DCData (and thus DTS-X) track files
- 2. v2.5.12 creates broken Atmos track files (incorrect ULs)
- The fix for this involved the following changes:
- 1. ASDCP::DCData::(MXFReader|MXFWriter) are no longer base classes of
- ASDCP::ATMOS::(MXFReader|MXFWriter).
- 2. New UL values have been added to carry the original Atoms UL values:
- a. DolbyAtmosDCDataWrappingFrame
- b. DolbyAtmosDCDataEssence
- c. DolbyAtmosDCDataDescriptor
- 3. ASDCP::ATMOS::(MXFReader|MXFWriter) have been modified to use the
- DolbyAtmosDCData* UL values.
- 4. ASDCP::DCData::MXFReader will parse files having either DCData* or
- DolbyAtmosDCData* UL values.
- 5. ASDCP::DCData:: MXFWriter continues to use DCData* UL values from ST
- 429-14
- o Some optional parameters of the MXF metadata packs were being erroneously
- initialized with a value of zero (0), such as GenericPictureEssenceDescriptor
- ::SignalStandard, GenericPictureEssenceDescriptor::SampledXOffset(0), etc.
- o Added higher edit rates (96, 100, 120) to the cinema TimedText_Parser
-
- o Defined bool ASDCP::UL::operator<(const UL& rhs) const, which is needed to
- carry out the version-insensitive lookup policy when searching for ULs in a
- std::map<> of UL entries.
- o New files: src/info.in src/CMakeLists.txt
- o Removed filess: AS_DCP_DCData_internal.h
-
-
-2016-03-17 - bug fixes, 2.5.12
- o Changed default UNIX file permissions to "666"
- o Changed default UNIX file permissions to "777"
- o Added missing initializer for caltime::offset

- o Provided a stub implementation for Kumu::DirScannerEx (A real
- implementation will follow soon.)
- o Added as-02-info program
- o Added Seek() method to PCM parsers
- o Added CMakeLists.txt
-
-
-2015-11-10 - bug fixes, IMF text, pink noise, 2.5.11
- o I moved personal dev environment from older gcc to newer clang. Many
- small changes were made to satisfy the new compiler:
- - Altered many printf format codes to use the correct format for the
- given integer type.
- - Parenthesized some expressions to clarify previously ambiguous
- expectation about precedence.
- - Created macro KM_MACOSX for use in OS-specific code selection.
- - Removed last uses of the old C-language abs(), now using Kumu::xabs().
- - Removed last uses of the old C-language atoi(), not using strtol().
- o Added platform-independent call Kumu::GetExecutablePath() (to be tested
- on win32).
- o Added new capabilities to Result_t.
- o Added imlementation of SMPTE ST 2092-1 pink noise generator.
- o Added pinkwave CLI utility.
- o Added font support to the IMF timed-text wrapper.
- o Fixed a bug that was causing Array properties to be written without
- the (count, length) header (from PAL).
- o General review of Batch/Array distinction throughout the project.
- o Cleaned up definitions of optional properties in all MXF metadata packs.
- o Fixed Win32 build (from Crowe).
- o Fixed a bug that caused incorrect failure when parsing JPEG 2000
- codestreams having fewer than five decomposition levels. (from Korneder).
- o Fixed missing UUID generation in some instances of the MCALinkID property.
- o Added -w option to asdcp-wrap to support use of WTF label with MCA.
- o Altered asdcp-wrap to recognize "-C <UL>" when MCA is being used.
- o Fixed broken -A <w>/<h> option in as-02-wrap and phdr-wrap.
- o asdcp-wrap and as-02-wrap now allow split channel groups in MCA labels.
-
-
-2015-02-23 - bug fixes, 2.4.10
- o Fixed a new bug introduced by the fix to large numbers of subtitle ancillary
- resources.
- o Added support for generic Aux Data (ST 429-14) to asdcp-wrap.
-
-
-2015-02-19 - PHDR feature, bug fixes, 2.4.9
- o Modified PCMParser and PCMParserList to return partial frame buffers at the
- end of a WAV input file. This was needed to allow wrapping all samples into
- an AS-02 audio file (which is clip-wrapped) in the case where the input file
- has an odd number of samples with respect to the frame buffer size being
- used. If there is more than one input file the length of the last buffer
- will be determined by PCMParserList to be the shortest of the input files.
- Prior to this change, partial samples in an input WAV file have been
- abandoned (i.e., not written out to the MXF file). As a result, AS-DCP
- applications will have to decide whether to abandon the partial last frame
- (usually detected by testing frame_buffer.Size() != frame_buffer.Capacity())
- or write it to the MXF file. Programs written to the old API will write the
- partial frame (i.e., new behavior.) This should not be harmful since the
- remainder of the buffer is zeroed and the output file will contain one
- additional edit unit compared to the previous version.
- o asdcp-wrap has been modified to test for the partial buffer and by default
- will complain and abandon the buffer (i.e., same behavior but with a warning
- message.) A new command line switch (-g) alters this behavior and writes
- the buffer to the MXF file (it still warns the user that this condition is
- present.)
- o as-02-wrap now wraps all samples from the input file to the MXF file. There
- is no padding, the clip is exactly the set of samples from the input.
- o as-02 unwrap is temporarily restricted to creating wav files that are
- aligned with the frame buffer size. This means that the output file will
- be longer than the original WAV input in the case where the input file has
- an odd number of samples with respect to the frame buffer size being used.
- The pad samples are zero (silence).
- o Modified CalcFramesFromDurationInSamples() to increment the count by one for
- the case where the input file has an odd number of samples with respect to
- the frame buffer size being used (previously it truncated the odd samples.)
- o Fixed ST 429-5 / ST 2067-5 wrapping to increase header space when ancillary
- resources are present (fixes a bug that cause the header to overflow the
- allotted space when large numbers of PNG files were present.)
- o Refactored GetXMLDocType() to use the XML parser.
- o Added ParseFirstFromString() method to Kumu::XMLElement
- o Removed Kumu::StringIsXML from the API.
- o Added ASDCP::MXF::RGBALayout type
- o Added J2CLayout property to JPEG2000PictureSubDescriptor
- o Changed km_token_split() to retain empty elements in the output list
- o Added PHDR wrapping for AS-02.
- o Added J2CLayout property to the JPEG2000PictureSubDescriptor. This
- support is preliminary: the Raw data type is being used instead of
- RGBALayout type, which will be in the next release.
-
-
-2014-10-2 - Bug fixes and enhancements, 2.2.6
- o Fixed erroneous 377-4 MCA identifier in AS_DCP_PCM dump routine
- o Fixed erroneous byte 13 in
- WaveAudioDescriptor_ReferenceAudioAlignmentLevel label
- o Added missing implementation of -W option to as-02.unwrap
- o Fixed erroneous use of d-cinema ChannelAssignment label in as-02-wrap
-

-
-
-2013-07-02 – IMF/AS-02 support, bug fixes 2.0.0
- o Massive refactoring of internals to allow easier implementation
- of AS-02. Some API changes were made as well (note that
- OPAtomHeader is now OP1aHeader and RIP is no longer part of the
- OP1aHeader.) If you are using this project as a library (and
- especially if you are keeping patches against it) PLEASE TAKE
- TIME TO EVALUATE THIS RELEASE THOUROUGHLY BEFORE ADDING IT TO
- YOUR RELEASE PATH.

- exceptions: LEAD indexes are not supported by the MXF writers
- and interlace images are not yet supported.
- o Added support for MCA labels (ST 428-12) to asdcp-wrap. Note
- that this project is still in the early stages of interop testing
- so errors are likely present and don't expect any server to
- make use of this feature.

- labels (corresponds with publication of ST 429-2:2011).
- o Exposed MXF object interface (MXF.h, Metadata.h) via ASDCP MXFReader
- and MXFWriter classes.
- o Added UL values from ST 377-4:2012. >>>>NOTE: These are preliminary
- values, subject to change upon final publication of not only ST 377-4
- but also the relevant registries. This is a good time to compare them
- to the standard and complain if you think they are wrong!
- o Added MCALabelSubDescriptor, AudioChannelLabelSubDescriptor,
- SoundfieldGroupLabelSubDescriptor, and
- GroupOfSoundfieldGroupsLabelSubDescriptor (from ST 377-4:2012) to
- Metadata.h
- o Changed some internals to make MXFWriter::OPAtomHeader() work correctly.
- o Split asdcp-test into several different programs to help relieve
- the impenetrable-list-of-arguments problem. asdcp-wrap, asdcp-unwrap
- and asdcp-info take the place of asdcp-test's -c, -x and -i options,
- respectively. asdcp-util contains the remaining functions. Note that
- asdcp-test is now DEPRECATED, new functionality and bug fixes will be
- aimed at the new tools. Also note that some options and calling
- conventions are different for the new tools as compared to asdcp-test.
- Please read the synopses and make sure you understand the new idioms.
- o asdcp-wrap has a new argument, -C <UL>, that writes the given UL to the
- ChannelAssignment item in the WaveAudioDescriptor (only useful when
- writing PCM essence).
-
-
-2011-11-30 - bug fixes v1.8.44

-
-2011-08-30 - bug fixes, enhancements v1.8.41
- o UL version byte now ignored when comparing UL values.
- o Changed the version byte in the TimedTextEssence UL to 0x01. There
- is no published Essence Keys registry so it can't have a maintained
- version number.
- o JP2K Sequence Parser modified to skip directory entries that
- are not files in the case where the parser is initialized with
- a directory path. When initialized with a list of file names
- this check is not performed. Based on a hint by Steve Quartly.

- o Fixed bug in JP2K PictureDescriptor initialization in
- JP2K::MXFReader::OpenRead() and JP2K::MXFSReader::OpenRead()
- o Once again fiddling with AvgBbs. How can something so simple
- be such a constant cause of trouble? Tested with 1-, 2- and
- 6-channel input Wav files.
- o asdcp-test now accepts a directory name when making PCM
- files (-c). The directory name should be the only filename
- argument. All files in the directory must be Wav files
- (mixed channel sizes OK). Files are sorted alphabetically by
- filename. Hint: use numeric name infix to define order:
- my_movie_00_L.wav
- my_movie_01_R.wav
- my_movie_02_C.wav
- my_movie_03_LFE.wav
- my_movie_04_LS.wav

-
-
-2009.11.06 - bug fixes, enhancements, v1.5.29
- o Fixed a bug that could cause HMAC values to be incorrectly
- stored in MXF files. Files created with versions of asdcplib
- prior to this version may have incorrect HMAC values.
- o Improved handing of XML files for MXF wrapping.
- o Jpeg2000 codestream EditRate and SampleRate mismatches
- now warns instead of returning an error.
- o Improved error handling in Jpeg2000 sequence parsing routines.
- o Added two methods to Kumu::Timestamp, AddSeconds(), to add (or
- subtract) seconds to a time value, and GetSecondsSinceEpoch()
- to get the number of seconds since the unix epoch.
- o Added new option to asdcp-test, '-a', to specify a UUID when
- creating MXF files.
- o Added support for specifying the intrinsic duration of MXF files
- containing timed text.

-
-
-2009.05.21 - bug fixes, v.1.4.24
- o Fixed a bug that caused incorrect SubDescriptors UL values to be
- written into interop format MXF track files. Note that this involved
- a substantial reorganization of MXF internals. Please test thoroughly
- in your application before using in production. Note that this is a
- significant bug fix and track files created with 1.4.22 may be incompatible
- with other systems.
-
-
-2009.04.09 - SMPTE format fixes, enhancements and bug fixes, v.1.4.22
- o asdcplib now uses GNU autotools on POSIX systems to configure
- and build. See "./configure" for details. Note that two options,
- --enable-freedist and --with-python are not enabled in the free
- version of asdcplib and should not be used.
- o Added build option (CONFIG_RANDOM_UUID) to enable mixed case UUID
- generation when environment variable KM_USE_RANDOM_UUID is defined.

- SMPTE format timed text track files that do not define a starting
- frame.
- o Updated ULs for SMPTE format track files.
- o SampleRate added to JP2K metadata
- o Support for wrapping 96kHz WAV files added.

-
-
-2008.02.16 - SMPTE format fixes, bug fixes v.1.3.18
- o Added correct SMPTE UL for StereoscopicPictureSubDescriptor.
- o Exposed JP2K metadata parser as ParseMetadataIntoDesc().

- and WriteFrame() methods (allows simpler integration with other
- single-buffer code).
- o Improved detection of JPEG Interop stereoscopic files.
- o Win32 build fixes (Thanks to Mike Crowe at DTS).
- o Added the WITH_MD macro to the makefile. Set this value to one
- to build Win32 with /MD[d] instead of /MT[d].
- o The Generic Container UL has been added to the EssenceContainers
- set in the header partition pack for encrypted files. It has always
- been there in plaintext files.
- - Below this point the changes are internal and should not affect you
- unless you use Kumu directly.
- o Major refactoring of KM_log.[h|cpp].
- o Fixed buffer re-sizing issue in Kumu::ByteString.
- o Replaced type IdentifierList with ArchivableList.
- o Added COPYING file to the release bundle.
-
-
-2007.12.13 - Bug fixes v.1.2.17
- o Changed Result_t implementation to use int instead of long, which
- was causing trouble on some 64 bit platforms.
- o Fixed EKLV HMAC. NOTE: Breaks backward compatibility with older
- Interop files. To validate these files, use asdcplib-1.1.14. This
- should not cause too much trouble since files with broken and
- non-broken HMAC have been in the wild for years without issue.
- o Fixed HMAC sequence numbering in encrypted stereoscopic files.
- o Finished stereoscopic test targets in the makefile.
- o Fixed the win32 build, now expects VS2005 compiler by default,
- use WITH_VC6=1 top get VC6 flags.
- o Stereoscopic and Timed Text modes now have SMPTE UL values.
- NOTE: SMPTE 429-5 and 429-10 are not yet published. It is possible
- that these UL values may change before publication. Please use
- caution when using these features for production work.
- o Changed a bunch of symbol names in the 429-5 implementation to
- better match the spec.
- o Added -U option to asdcp-test to dump the UL library to stdout.
- o Fixed erroneous placement of the PictureEssenceCoding UL in JP2K
- files (Interop and SMPTE modes).
-
-
-2007.10.22 - Timed Text, Stereoscopic Picture and Bug fixes v.1.2.16
- o Significant API changes have been made. Please read all entries
- in this changelog to be sure you understand the changes. Also
- note that some changes have been made to LS_MXF_SMPTE files that
- are incompatible with earlier releases (e.g., EKLV HMAC). If
- you are looking for a stable interop release, use v.1.1.14.
- o Fixed RFC 2104 HMAC implementation for LS_MXF_SMPTE only. The
- broken implementation has been maintained for Interop mode.
- o Added support for draft SMPTE 429-5 Timed Text Track File. This
- is still waiting for official SMPTE ULs, so do not use it for
- shipping products. An XML parser is needed to create a Timed
- Text Track File; Expat is now an optional part of the build.
- Make with WITH_XML_PARSER=1 to link with Expat. If you do not
- link with expat, you will get an error when using the TimedText::
- DCSubtitleParser class. See also S429-5-cgi.cpp for an example
- that shows how to serve plaintext MXF file elements directly via
- HTTP.
- o Added support for draft SMPTE 429-10 Stereoscopic Picture Track
- File, including the JPEG Interop version. This is still waiting
- for official SMPTE ULs, so do not use it with LS_MXF_SMPTE for
- shipping products.
- o Refactored the following files as a side-effect of the above
- work: AS_DCP_JP2K.cpp AS_DCP_MPEG2.cpp AS_DCP_PCM.cpp
- AS_DCP_MXF.cpp AS_DCP_internal.h MXF.[h|cpp] MXFTypes.[h|cpp]
- Metadata.[h|cpp] h__Reader.cpp h__Writer.cpp klvwalk.cpp.
- WARNING: While significant effort has been extended to make sure
- that these changes do not affect existing stable file support,
- users are cautioned to test this release thouroughly.
- o Added a large set of filesystem path manglers to KM_fileio.h. See
- path-test.cpp for example usage. The path manglers have not yet
- been tested on win32 platforms (they are currently used only by
- the Timed Text module.
- o The PathIsFile(), PathIsDirectory() and FileSize() subroutines
- have been modified to accept const std::string& instead of
- const char*.
- o Added namespace and parsing support (Expat) to Kumu::XMLElement
- (currently used only for Timed Text support). Also added some
- new accessors.
- o Altered MXF::UTF16String to use mbtowc() and wctomb().
-
-
-2007.03.31 - Bug fixes v.1.1.14
- o Fixed KeyFrameOffset value in MPEG wrapping to have negative
- value. This is probably not yet complete for handling all
- types of GOPs. Please send chunks of MPEG-2 VES that you
- find which break this. Thanks to Doremi.
- ** no other file format changes in this release **
- o Fixed error in RIP interpretation when reading arbitrary (i.e.,
- non-MXF) files.
- o Fixed a memory leak in ASDCP::MXF::OPAtomHeader when used
- in read mode. Thanks to Mahesh Bajaj for pointing out this
- bug and the one above.
- o Removed asserts from KM_fileio, replaced with RESULT_WRITEFAIL
- return value statements.
- o Added -s and -p to the makefile install target.
- o Altered ByteString behavior to use target Length() in copy
- operations (instead of Capacity()).
- o Added new Set() method to ByteString.
- o Fixed a bug in ByteString::Unarchive() that caused the operation
- to fail when the buffer was smaller than the read (i.e., when
- Capacity() was called).
- o Added IdentifierList class to KM_util.h.
- o Changed some Error() messages to Debug() in Wav.cpp
- o Revived jp2k-test.cpp and asdcp-mem-test.cpp (they both had
- stale #includes).
-
-
-2007.02.15 - Bug fixes v1.1.13
- o Removed 'VDescObj->SampleRate.Numerator = VDesc.FrameRate;'
- from MPEG2_VDesc_to_MD() in AS_DCP_MPEG2.cpp, was line 76.
- o Added KM_TEST_NULL_STR_L() and KM_TEST_NULL_L() macros to
- KM_log.h. These versions log the location of the null value.
- Macros are now used in any module that includes KM_log.h.
- o MPEG2 VES with run of zero values at the head is now OK.
- o Increased VESHeaderBufSize to 16K.
- o Added makefile support for local OpenSSL in ../openssl, if
- present.
- o The Kumu::PathIs*() functions now return false if a null or
- empty string is given (used to be an assert).
- o Cleaned up the install target in the makefile.
- o Fixed SMPTE 429-6 HMAC -- FIPS 186-2 implementation was
- laughably incorrect. Thanks to Doremi for pointing this out.
- o Removed default parameter to HMACContext::InitKey().
- o Cleaned up messages and CLI arg handling in asdcp-test.
-

- files (MXF Interop mode).
- o Added -t option to asdcp-test (SHA-1 digest with Base64 output
- on stdout).
- o Fixed Sub Descriptor reference bug (Thanks to Denis Leconte
- for dogged determination).
- o Added directory-of-wav detection to RawEssenceType()

- want to set SourcePackageID.
- o Fixed compiler warnings on some Linux platforms
- o Fixed the build so that BUILD_DIR is no longer created
- as a dependency.

- is a symbolic link (unix only).
- o Altered Kumu::FileWriter::OpenWrite to use file creation
- mode 0664 (was 0644) (unix only).
- o Added Kumu::WriteStringIntoFile() subroutine.
-
-
-2006.04.05 - Bug fixes and new stuff v1.1.7
- o Fixed a bug in the MPEG parser that caused it to fail when
- handling start codes spanning buffer boundaries
- o Added wavesplit and blackwave utility programs
- o Added support for revised SMPTE HMAC key derivation when
- using LS_MXF_SMPTE
- o Refactored platform compatibility and general utilities
- into a new sub-library "Kumu". There are no new build
- steps or dependencies, but some important things have
- changed:
- + Result_t is no longer an enum, it is now a class.
- Library result codes are now declared as const objects
- like this:
-
- const Kumu::Result_t RESULT_FORMAT (-101, "The file...");
-
- The macros ASDCP_SUCCESS and ASDCP_FAILURE still work
- the same way thanks to an operator overload for type long.
- See KM_error.h for more information.
- + The logging interface has been moved out of AS_DCP.h
- and into KM_log.h
- o Some of the command line utilities that were using headers
- other than AS_DCP.h have been changed to use the Kumu
- equivalents. If you have code based on those utilities, you
- will have to update by hand.
- o Added new types to the EssenceType_t enum.
- o The guard macro for Win32 code has changed from WIN32 to
- KM_WIN32.
-
-
-2006.03.2x - new stuff
- o Proper handling of stream-id byte of essence UL values
- o writes 3-partition files, reads 2-part or 3-part
-
-
-2006.03.16 - bug fixes plus
- o Removed SMPTE_LABELS compile-time option. The reader will now
- silently accept either SMPTE or MXF Interop labels, the writer
- can be instructed which to use at runtime. Default is Interop.
- o Added an AIFF reader. Support is preliminary, it works with the
- AIFF files I have on hand.
- o More code refactoring. More to come.
-
-
-2006.03.09 - full read-write
- o Removed ASDCP_WITHOUT_OPENSSL compile-time option.
- o Full read/write now working on new MXF library
-
-
-2005.00.00 - A New Hope
- o The temporary mxf-lite has been removed. MXF files are now
- managed via the objects in KLV.h, MXFTypes.h MXF.h and
- Metadata.h. This release does not support writing MXF files.
- o Fixed a header interpretation error in the Wav parser.
-
-
-2005.00.00 - The Reformation
- o Removed mxflib as a dependency by forking the necessary
- functions and placing them in the mxf-lite subdirectory.
- Please note that the very heavy modifications done here
- render all comparisson to mxflib code a substantial task.
- All errors are now mine and users are warned not to bug
- Oliver or Matt for help with this code. The version of
- mxflib at the time of the fork was: 0.5.1.3.
-
-
-2005.06.03 - bug fixes v0.10.18
- o Updated UL batch to include GC UL.

- o Fixed JP2K essence container label.
-
-
-2005.05.02 - bug fixes v0.10.16
- o Reorganized internal files, added file reader object, added OS
- portability header, removed and renamed some files. If you have a
- patch against previous versions of the source, you should check
- it thoroughly.
- o Added RGBA attributes to JP2K descriptor.
- o Changed interface to CodestreamParser.
- o Added JP2K parser implementation. It is parsing each frame but is
- not yet being used to populate the descriptor.
- o Added 48fps option for `asdcp-test -p`.
- o Added picture rate constants to AS_DCP.h (23.976, 24, 48).
- o Added sample rate constant to AS_DCP.h (48k).
- o Changed asdcp-test to encrypt picture headers by default
- (plaintext offset will be 0), added -E option to allow
- plaintext headers.
-
-
-2005.04.28 - bug fixes v0.9.15
- o The XML descriptors for the crypto DMS have moved in mxflib to
- the file DMS_Crypto.xml (they were in DMS_DCPENC.xml). Older
- installations should update the file from mxflib.
- o Added Close() and Seek() to ~MyFileWriter(), cleaned up headers
- o Added UUID generator output mode (-u).
- o Added -S option to extract PCM essence into stereo wav files
- o Added more UL testing and conformance checking.
- o Added macro SMPTE_LABELS which causes the library to be built
- with SMPTE (as opposed to MXF Interop) labels. This is not
- set by default, and currently only affects the PCM container
- label and encrypted element label.
- o Cleaned up the GNUmakefile test targets, the source files
- are now named with the TEST_FILE_PREFIX macro.
- o enabled 23.976-framed PCM (2002 samples per frame)
- o The size of the asdcp-test frame buffer for picture essence
- may now be set from the command line (-b). The default is 4MB.
- o h__Reader::ReadEKLVPacket() now tests the UL (duh) and switches
- on the value, allowing plaintext and ciphertext frames to
- be mixed in the file.
- o Fixed error in UUID generator format.
- o JP2K files now use the GenericPictureDescriptor to store
- ContainerDuration and SampleRate. SampleRate is mapped
- to EditRate in the PictureDescriptor struct. This fixes
- the second caveat from the 0.8.13 release.
- o Fxed bug in PCMParserList that was miscalculating the extent
- of a PCM sample. This bug did not affect API users, it was
- only present in asdcp-test.
- o Fixed EditRate on PCM files (was showing sample rate)
- o Fixed Encrypted Essence Container UL
- o Fixed BlockAlign value for PCM essence
-
- - The following changes were provided by Jeff Loewenguth
- - Thanks Jeff!
- o Moved the DMS CryptographicFramework entry from the material
- package to the source package
- o Fixed erroneous Source Essence Container Label value
- o Fixed broken sort of JP2K frames in JP2K parser
- o Added FindFrameGOPStart() method to the MPEG2 MXFReader
- o Added missing length values for EKLV packets without HMAC
- o -x with JP2K essence writes to files with 6 digit names
- (up from 5 digits).
- o The Key ID may now be specified as an argument to asdcp-test
- (-j <key-id-string>)
-
-
-2004.12.30 - bug fixes + wav files v0.8.14
- o Added WAV file write to asdcp-test (uses mxflib::waveheader_t).
- o Three-partition files reading properly. adscplib still writes
- two-partition files.
- o Changes in the mxflib WAV essence parser API had broken
- asdcplib's ability to read essence from a WAV file. I have
- fixed this bug, but at the expense of breaking compatibility
- with older versions of mxflib. Beware!
- o Removed redundant (but working) bin-text-bin conversions.
-
-
-2004.12.23 - JPEG 2000 support v0.8.13
- o Reads/writes JPEG 2000 essence in plaintext and ciphertext
- with the following caveats:
- - The Picture Essence Descriptor is empty.
- - Because there is no essence descriptor, the reader code
- in asdcp-test has no idea how many frames are in the file
- and ends with an out-of-bounds frame error. This error
- is being suppressed in asdcp-test for the current release.
- o Still broken when reading three-partition files.
-
-
-2004.10.22 - fixes and UL updates v0.7.11
- WARNING: COMPATIBILITY BREAKPOINT
- Files created with this and future versions of this library are
- not compatible with previous versions of this library. As you
- might suspect, files created with previous versions of this
- library are not compatible with this and future versions.
-
- o h__Reader will now open a three-partitition file (untested)
- o Moved DMS from Material partition to File partition
- o Added length fields to appropriate places in EKLV packet

- following caveats:
- - no HMAC support
- - no plaintext offest support
- - no raw ciphertext read support
- o moved to reflecting the whole KLV triplet in the CBR
- index (now incompatible with mxflib, still searching
- for info about what's "right")

- o tested under win32 and linux. FreeBSD and Darwin do not work
-
-
-2004.02.04 - First release (v0.1.1):

- will cleanly support a DSO (or DLL). Let me know if DSO
- support is important to you.
- o Nothing is thread safe. Thread safety was not a requirement
- in the initial project definition. Thread safety may be added
- above the mxflib/klvlib level. Let me know if it is important
- to you.
- o The files xmldict.xml and types.xml must be in the current
- directory when the program is run. The files are supplied
- with mxflib. Runtime location of the files is not currently
- a project goal. Comments on how best to handle this situation
- would be appreciated. See AS_DCP.cpp at init_mxf_types()
- for a more detailed discussion.

+# AS-DCP Lib
+
+## Introduction
+
+The asdcplib library is an API and command-line tool set that offers
+access to files conforming to the sound and picture track file formats
+developed by the SMPTE Working Group DC28.20 (now TC 21DC).
+
+Support has since been added for SMPTE ST 2067-5 "IMF Essence
+Component", AKA "AS-02", which was published and is maintained by
+SMPTE TC 35 PM. The initial draft of this code was donated by
+Fraunhofer IIS and was created by Robert Scheler and Heiko Sparenberg.
+It carries additional copyright information which should be listed
+whenever you link the AS-02 elements of the library. Please look at
+the top of the AS-02 files to see this copyright information.
+
+Support for ST 20XX OpenEXR was developed and contributed by Bjoern
+Stresing, Patrick Bichiou and Wolfgang Ruppel, supported by AMPAS.
+It carries additional copyright information which should be listed
+whenever you link the AS-02 elements of the library. Please look at
+the top of the AS-02 files to see this copyright information.
+
+AS-02 support is carried in separate object modules, so unless you
+`#include <AS_02.h>` and link `libas-02.so` you are still using plain old
+asdcp.
+
+
+## Documentation
+
+This library is intended (but of course not limited) for use by
+developers of commercial D-Cinema and IMF products and for commercial
+mastering toolchains. The documentation is terse and sparse.
+
+The API documentation is mostly in AS_DCP.h. and AS_02.h Read those
+files for a detailed description of the library's capabilities. Read
+asdcp-*.cpp and as-02-*.cpp files for library usage examples. The
+command-line utilities all respond to -h.
+
+Also, of course, the various SMPTE and ISO standards that underly all
+of this work should be well understood if you want to tinker with
+anything, or, in some cases, understand what properties are required
+in a particular supported use case (e.g., selecting audio channel labels.)
+
+
+## CLI Programs
+
+### Standard Utilities
+
+`asdcp-test` - DEPRECATED Writes, reads and verifies AS-DCP (MXF) track files.
+
+`asdcp-wrap` - Writes AS-DCP (MXF) track files.
+
+`asdcp-unwrap` - Extracts essence from AS-DCP (MXF) track files.
+
+`asdcp-info` - Displays information about AS-DCP (MXF) track files.
+
+`asdcp-util` - Calculates digests and generates random numbers and UUIDs.
+
+`as-02-wrap` - Writes AS-02 Essence Component files.
+
+`as-02-unwrap` - Extracts essence from AS-02 Essence Component files.
+
+`kmfilegen` - Writes and verifies large files using a platform-independent format. Use it to test issues related to large files.
+
+`kmuuidgen`, `kmrandgen` - generate UUID values and random numbers.
+
+`wavesplit` - Splits a WAVE file into two or more output files. Used to untangle incorrectly-paired DCDM sound files.
+
+`blackwave` - Write a WAVE file of zeros.
+
+`pinkwave` - Write a WAVE file of SMPTE ST 2095 pink noise.
+
+`j2c-test` - Displays information about JP2K codestreams.
+
+### PHDR
+
+An experimental feature, Prototype for High Dynamic Range is a wrapper
+for the IMF application that allows JPEG-2000 codestreams to be paired
+with opaque blobs of metadata. AS-02 support must be enabled to
+build this feature, so --enable-as-02 must be enabled if
+--enable-phdr is to be used. The following executable programs will be
+built:
+
+`phdr-wrap` - Writes AS-02 PHDR Essence Component files.
+
+`phdr-unwrap` - Extracts essence from AS-02 PHDR Essence Component files.
+
+
+## Historical Notes
+
+This work was originally funded by Digital Cinema Initiatives, LLC
+(DCI). Subsequent efforts have been funded by Deluxe Laboratories,
+Doremi Labs, CineCert LLC, Avica Technology and others.
+
+The asdcplib project was originally exchanged by FTP. The project was
+on [SourceForge](https://sourceforge.net/projects/asdcplib) between
+2005 and 2008, when it moved to a release-only distribution via
+[CineCert](https://www.cinecert.com/asdcplib/download). As of late
+February 2019, its new home is on [github](https://github.com/cinecert/asdcplib).
+
+In the eraliest days, the project depended upon the
+[mxflib](http://sourceforge.net/projects/mxflib) project. Because of
+its focus on covering the whole of the MXF specifications, mxflib is
+considerably larger and more complex that what was required for the
+AS-DCP application. For this reason I developed a dedicated MXF
+implementation. Special thanks to Matt Beard and Oliver Morgan for
+their great work and support.
+
+Thanks also to the members of the SMPTE DC28.20 packaging ad-hoc group
+and the members of the MXF Interop Initiative for their encouragement
+and support. Special thanks to Jim Whittlesey and Howard Lukk at DCI
+for proposing and supporting this project.
