4 The asdcplib library is a set of objects that offer
5 simplified access to files conforming to the sound and
6 picture track file formats developed by the SMPTE Working
7 Group DC28.20 (now TC 21DC).
9 Recently, support has also been added for SMPTE draft ST
10 2067-5 "IMF Essence Component", AKA "AS-02". This code was
11 donated by Fraunhofer IIS. It carries additional copyright
12 information which should be listed whenever you link the
13 AS-02 elements of the library. Please look at the top of
14 the AS-02 files to see this copyright information.
16 AS-02 support is carried in separate object modules, so
17 unless you #include <AS_02.h> and link libas-02.so you are
18 still using plain old asdcp.
20 This work was originally funded by Digital Cinema Initiatives,
21 LLC (DCI). Subsequent efforts have been funded by Deluxe
22 Laboratories, Doremi Labs, CineCert LLC, Avica Technology
25 **The asdcplib project was originally housed on SourceForge.
26 The project has moved to http://www.cinecert.com/asdcplib/
28 The project formerly depended upon the mxflib project. Because
29 of its focus on covering the whole of the MXF specifications,
30 mxflib is considerably larger and more complex that what I
31 require for this application. For this reason I have created
32 a dedicated MXF implementation that is now part of this
33 library. Special thanks to Matt Beard and Oliver Morgan for
34 their great work and support.
36 Thanks also to the members of the SMPTE DC28.20 packaging
37 ad-hoc group and the members of the MXF Interop Initiative
38 for their encouragement and support. Special thanks to
39 Jim Whittlesey and Howard Lukk at DCI for proposing and
40 supporting this project.
45 This library is intended (but of course not limited) for
46 use by developers of commercial D-Cinema products (and now
47 IMF!). It is designed to be easily integrated into a wide
48 variety of development environments. Commercial users are
49 strongly urged to use static linking (at least where you use
50 this library) to prevent malicious in-field replacement of
51 critical system modules. This recommendation should be
52 considered wherever Open Source or Free software is being
53 used in conjunction with critical security parameters, such
54 as cryptographic keys.
56 The author strives mightily to provide an API that is completely
57 independent of operating system and other library dependencies,
58 and which allows selective replacement of some modules for
59 local needs. Specifically, the essence parsers and OpenSSL
60 crypto functions can be replaced by linking to alternative
61 implementations of the ASDCP:: objects which provide those
64 AS_DCP.h contains the entire AS-DCP API. You do not need to
65 read any of the other files, except maybe asdcp-test.cpp which
66 contains detailed usage examples of each of the API's services.
67 The KM_* files may be of interest for general development
68 support, but may be ignored if all you want is simple AS-DCP
71 Likewise, draft 2067-5 "IMF Essence Component" (AS-02) support
72 is entirely contained in AS-02.h
77 On more-or-less POSIX systems (OS X, Linux, and BSD), GNU make and
78 autotools are required to build asdcplib. The same configure script
79 will also build this package on Windows machines with Cygwin and
80 MinGW installed. For those Windows users who would prefer to build
81 this natively, an "nmake" build file and instructions can be found
82 in the win32 subdirectory.
84 OpenSSL is also required, any recent version should be fine. See
85 http://www.openssl.org/ for more information and download instructions.
87 Optional support for writing Timed Text Track Files is supported by
88 either Xerces-C or Expat. See http://xerces.apache.org/xerces-c/ or
89 http://expat.sourceforge.net/ for source and build instructions.
91 To configure and build, type './configure' followed by 'make'. There
92 are several test targets on the POSIX side, but you need to assemble
93 a set of test files to use them. AS-02 support can be enabled with
96 I have tested this build on win32, Linux, OpenBSD, and Darwin
97 platforms. Others may work as well.

135 build this feature, so --enable-as-02 must be enabled if
136 --enable-phdr is to be used. The following executable programs will be
139 phdr-wrap - Writes AS-02 PHDR Essence Component files.
141 phdr-unwrap - Extracts essence from AS-02 PHDR Essence Component files.
146 The API documentation is mostly in AS_DCP.h. and AS_02.h Read those
147 files for a detailed description of the library's capabilities. Read
148 asdcp-*.cpp and as-02-*.cpp files for library usage examples. The

266 o Modified the IndexEntry parser to ignore additional bytes belonging to slice
270 2016-05-06 - bug fixes, 2.5.14
272 o Release 2.5.12 caused two problems with Atoms and DTS-X wrapping that are
273 addressed by this release. The UL values that were changed to correct the
274 DCData (ST 429-14) implementation had two unintended side-effects:
275 1. v2.5.12 cannot read old DCData (and thus DTS-X) track files
276 2. v2.5.12 creates broken Atmos track files (incorrect ULs)
277 The fix for this involved the following changes:
278 1. ASDCP::DCData::(MXFReader|MXFWriter) are no longer base classes of
279 ASDCP::ATMOS::(MXFReader|MXFWriter).
280 2. New UL values have been added to carry the original Atoms UL values:
281 a. DolbyAtmosDCDataWrappingFrame
282 b. DolbyAtmosDCDataEssence
283 c. DolbyAtmosDCDataDescriptor
284 3. ASDCP::ATMOS::(MXFReader|MXFWriter) have been modified to use the
285 DolbyAtmosDCData* UL values.
286 4. ASDCP::DCData::MXFReader will parse files having either DCData* or
287 DolbyAtmosDCData* UL values.
288 5. ASDCP::DCData:: MXFWriter continues to use DCData* UL values from ST
290 o Some optional parameters of the MXF metadata packs were being erroneously
291 initialized with a value of zero (0), such as GenericPictureEssenceDescriptor
292 ::SignalStandard, GenericPictureEssenceDescriptor::SampledXOffset(0), etc.
293 o Added higher edit rates (96, 100, 120) to the cinema TimedText_Parser
295 o Defined bool ASDCP::UL::operator<(const UL& rhs) const, which is needed to
296 carry out the version-insensitive lookup policy when searching for ULs in a
297 std::map<> of UL entries.
298 o New files: src/info.in src/CMakeLists.txt
299 o Removed filess: AS_DCP_DCData_internal.h
302 2016-03-17 - bug fixes, 2.5.12

312 o Corrected erroneous fixed-tag values in ActiveHeight, ActiveWidth,
313 ActiveXOffset, ActiveYOffset UL definitions.
314 o Provided a stub implementation for Kumu::DirScannerEx (A real
315 implementation will follow soon.)
316 o Added as-02-info program
317 o Added Seek() method to PCM parsers
318 o Added CMakeLists.txt
321 2015-11-10 - bug fixes, IMF text, pink noise, 2.5.11
322 o I moved personal dev environment from older gcc to newer clang. Many
323 small changes were made to satisfy the new compiler:
324 - Altered many printf format codes to use the correct format for the
326 - Parenthesized some expressions to clarify previously ambiguous
327 expectation about precedence.
328 - Created macro KM_MACOSX for use in OS-specific code selection.
329 - Removed last uses of the old C-language abs(), now using Kumu::xabs().
330 - Removed last uses of the old C-language atoi(), not using strtol().
331 o Added platform-independent call Kumu::GetExecutablePath() (to be tested
333 o Added new capabilities to Result_t.
334 o Added imlementation of SMPTE ST 2092-1 pink noise generator.
335 o Added pinkwave CLI utility.
336 o Added font support to the IMF timed-text wrapper.

338 the (count, length) header (from PAL).
339 o General review of Batch/Array distinction throughout the project.
340 o Cleaned up definitions of optional properties in all MXF metadata packs.
341 o Fixed Win32 build (from Crowe).
342 o Fixed a bug that caused incorrect failure when parsing JPEG 2000
343 codestreams having fewer than five decomposition levels. (from Korneder).
344 o Fixed missing UUID generation in some instances of the MCALinkID property.
345 o Added -w option to asdcp-wrap to support use of WTF label with MCA.
346 o Altered asdcp-wrap to recognize "-C <UL>" when MCA is being used.
347 o Fixed broken -A <w>/<h> option in as-02-wrap and phdr-wrap.
348 o asdcp-wrap and as-02-wrap now allow split channel groups in MCA labels.
351 2015-02-23 - bug fixes, 2.4.10
352 o Fixed a new bug introduced by the fix to large numbers of subtitle ancillary
354 o Added support for generic Aux Data (ST 429-14) to asdcp-wrap.
357 2015-02-19 - PHDR feature, bug fixes, 2.4.9
358 o Modified PCMParser and PCMParserList to return partial frame buffers at the
359 end of a WAV input file. This was needed to allow wrapping all samples into
360 an AS-02 audio file (which is clip-wrapped) in the case where the input file
361 has an odd number of samples with respect to the frame buffer size being
362 used. If there is more than one input file the length of the last buffer
363 will be determined by PCMParserList to be the shortest of the input files.
364 Prior to this change, partial samples in an input WAV file have been
365 abandoned (i.e., not written out to the MXF file). As a result, AS-DCP
366 applications will have to decide whether to abandon the partial last frame
367 (usually detected by testing frame_buffer.Size() != frame_buffer.Capacity())
368 or write it to the MXF file. Programs written to the old API will write the
369 partial frame (i.e., new behavior.) This should not be harmful since the
370 remainder of the buffer is zeroed and the output file will contain one
371 additional edit unit compared to the previous version.
372 o asdcp-wrap has been modified to test for the partial buffer and by default
373 will complain and abandon the buffer (i.e., same behavior but with a warning
374 message.) A new command line switch (-g) alters this behavior and writes
375 the buffer to the MXF file (it still warns the user that this condition is
377 o as-02-wrap now wraps all samples from the input file to the MXF file. There
378 is no padding, the clip is exactly the set of samples from the input.
379 o as-02 unwrap is temporarily restricted to creating wav files that are
380 aligned with the frame buffer size. This means that the output file will
381 be longer than the original WAV input in the case where the input file has
382 an odd number of samples with respect to the frame buffer size being used.
383 The pad samples are zero (silence).
384 o Modified CalcFramesFromDurationInSamples() to increment the count by one for
385 the case where the input file has an odd number of samples with respect to
386 the frame buffer size being used (previously it truncated the odd samples.)
387 o Fixed ST 429-5 / ST 2067-5 wrapping to increase header space when ancillary
388 resources are present (fixes a bug that cause the header to overflow the
389 allotted space when large numbers of PNG files were present.)
390 o Refactored GetXMLDocType() to use the XML parser.
391 o Added ParseFirstFromString() method to Kumu::XMLElement
392 o Removed Kumu::StringIsXML from the API.
393 o Added ASDCP::MXF::RGBALayout type
394 o Added J2CLayout property to JPEG2000PictureSubDescriptor
395 o Changed km_token_split() to retain empty elements in the output list
396 o Added PHDR wrapping for AS-02.
397 o Added J2CLayout property to the JPEG2000PictureSubDescriptor. This
398 support is preliminary: the Raw data type is being used instead of
399 RGBALayout type, which will be in the next release.
402 2014-10-2 - Bug fixes and enhancements, 2.2.6
403 o Fixed erroneous 377-4 MCA identifier in AS_DCP_PCM dump routine

419 o Added IMF App 2 edit rates in AS_02 namespace: EditRate_29_97,
421 o Revised AEC CBC context objects to copy the key rather than
422 keep the reference passed in to it.

431 caused unbounded reads.
432 o Fixed broken ByteString::ArchiveLength() method
433 o Fixed broken version numbers on SoundfieldGroupLinkID and
434 GroupOfSoundfieldGroupsLinkID UL values.
435 o Added DBOXMotionCodePrimaryStream and DBOXMotionCodeSecondaryStream UL
436 values to the internal dictionary.
437 o Added optional prefix handling to MCA label generator.
438 o Re-factored MCA label generator to include additional
439 metadata (Thanks to Mike Radford).
440 o Added new options to as-02-wrap.
443 2014-01-06 – Additional IMF/AS-02 support, bug fixes 2.1.1
444 o Fixed missing-index-partion bugs for AS-02 files.
445 o Moved LocalFilenameResolver into the AS_DCP public API so that it
446 can be used by other modules including AS-02.
447 o Did further refactoring of AS-02 Writer classes to separate CBR
448 and VBR indexing implementations.
449 o Fixed wave wrapping UL in clip-wrapped AS-02 files. Renamed some
450 UL constants to reflect "clip" or "frame" wrapping.
451 o Re-factored JP2K_PDesc_to_MD() and MD_to_JP2K_PDesc() to work
452 with GenericPictureEssenceDescriptor objects.
453 o Fixed a bug that was suppressing PictureComponentSizing,
454 CodingStyleDefault and QuantizationDefault when writing the
455 essence descriptor in a JP2K file (AS-DCP and AS-02).

464 o Changed bit rate display in asdcp-info from mebi-bits/s to
466 o Added "SMPTE" / "Interop" format type display to asdcp-info.
467 o Improved integration of ST 377-4 MCA concepts with ST 429-2 static
469 o Modified asdcp-wrap to assume -L when wrapping timed-text (since
470 there is no MXF text wrapping for Interop.)
471 o Added new EssenceType_t values for IMF/AS-02 track files.
472 o Added detection for AS-02 track files to ASDCP::EssenceType()

479 (thanks to both Kristof Provost and Franck Chopin)
480 o Fixed broken sample alignment in RF64Writer (thanks to Wolfgang
482 o Fixed win32 build (thanks to Dolby)
483 o fixed a bug that caused blackwave to only produce 96kHz WAV files.
484 (thanks to Stephane W)
487 2013-07-02 – IMF/AS-02 support, bug fixes 2.0.0
488 o Massive refactoring of internals to allow easier implementation
489 of AS-02. Some API changes were made as well (note that
490 OPAtomHeader is now OP1aHeader and RIP is no longer part of the
491 OP1aHeader.) If you are using this project as a library (and
492 especially if you are keeping patches against it) PLEASE TAKE
493 TIME TO EVALUATE THIS RELEASE THOUROUGHLY BEFORE ADDING IT TO
495 o Final integration of Fraunhoffer IIS code contribution. AS-02
496 files are now fully supported with some TODOs and two major
497 exceptions: LEAD indexes are not supported by the MXF writers
498 and interlace images are not yet supported.
499 o Added support for MCA labels (ST 428-12) to asdcp-wrap. Note
500 that this project is still in the early stages of interop testing
501 so errors are likely present and don't expect any server to
502 make use of this feature.

514 support for generic data track files as proposed in ST 21DC
515 and also Dolby Atmos track file support as a specialization.
516 o Added Dolby-contributed code to support generating the external
517 sync signal for d-cinema as proposed in ST 21DC.
518 o Added Dolby-contributed code to support RF64 WAVE files.
519 o Fixed UL error in ST 429-5 DM encoding (contributed by Dolby).
520 o Added ULs for ST 428-12 and Amd. 429-2 2013. Please check!
523 2013-02-20 - bug fixes, enhancements 1.10.48
524 o Refactored internals of the AS-DCP file readers. While no
525 changes in behavior are intended, users are cautioned to test
526 thouroughly before use in production.
527 o Fixed a bug in ReadAncillaryResource that was causing bogus HMAC
528 failures when reading resources from a file.
529 o Fixed premature-release bug in the Expat version of the XML parser.
530 Thanks to Carsten Feldheim (IIS) for the tip.
531 o Fixed -W option in asdcp-unwrap. Thanks to RGB.
532 o Added P-HFR support to asdcp-wrap (see URL for details:
533 http://isdcf.com/papers/ISDCF-HighFrameRate-DCP.pdf).
534 o Added support for SMPTE ST 428-21 "Archival Frame Rates".
535 o Added -P option to asdcp-wrap (inserts arbitrary UL into the
536 PictureEssenceCoding property when wrapping JP2K files.)
537 o Added support for 96 kHz files to blackwave.
538 o Added new path and string manglers to Kumu.
539 o Updated MCA ULs (I warned you...). Again please take some
540 time to proof this work against ST 477-4 including the latest
541 drafts of the registries.
542 Changed the version byte (8 0f 16) to 0x0e:
543 MCALabelSubDescriptor
544 AudioChannelLabelSubDescriptor
545 SoundfieldGroupLabelSubDescriptor
546 GroupOfSoundfieldGroupsLabelSubDescriptor
547 GroupOfSoundfieldGroupsLinkID
548 Changed bytes 8 and and 13 of SoundfieldGroupLinkID
549 Added items to the UL dictionary:
560 2012-08-07 - bug fix, 1.10.46
561 o Added missing zero-initializers to time values when parsing a
562 timestamp string (in the case where the optional [Thh:mm.[:ss]]
563 syntax is not present in an encoded string).
565 2012-03-06 - bug fixes, enhancements 1.9.45
566 o Removed ASDCP::Timestamp, all items that were of that class are now
567 of class Kumu::Timestamp
568 o Refactored Kumu::Timestamp to use KM_tai for internal representation
569 (replaced public Y M D, h, m, s variables)
570 o Refactored Kumu::Timestamp to use KM_tai for WIN32 builds
571 o Added UTC offset awareness to Kumu::Timestamp
572 o Replaced "long GetSecondsSinceEpoch(void) const" with
573 "ui64_t GetCTime() const"
574 o Corrected UL version segment in "7.1 DS" and "WTF" audio format
575 labels (corresponds with publication of ST 429-2:2011).
576 o Exposed MXF object interface (MXF.h, Metadata.h) via ASDCP MXFReader
577 and MXFWriter classes.
578 o Added UL values from ST 377-4:2012. >>>>NOTE: These are preliminary
579 values, subject to change upon final publication of not only ST 377-4
580 but also the relevant registries. This is a good time to compare them
581 to the standard and complain if you think they are wrong!
582 o Added MCALabelSubDescriptor, AudioChannelLabelSubDescriptor,
583 SoundfieldGroupLabelSubDescriptor, and
584 GroupOfSoundfieldGroupsLabelSubDescriptor (from ST 377-4:2012) to
586 o Changed some internals to make MXFWriter::OPAtomHeader() work correctly.
587 o Split asdcp-test into several different programs to help relieve
588 the impenetrable-list-of-arguments problem. asdcp-wrap, asdcp-unwrap
589 and asdcp-info take the place of asdcp-test's -c, -x and -i options,
590 respectively. asdcp-util contains the remaining functions. Note that
591 asdcp-test is now DEPRECATED, new functionality and bug fixes will be
592 aimed at the new tools. Also note that some options and calling
593 conventions are different for the new tools as compared to asdcp-test.
594 Please read the synopses and make sure you understand the new idioms.
595 o asdcp-wrap has a new argument, -C <UL>, that writes the given UL to the
596 ChannelAssignment item in the WaveAudioDescriptor (only useful when
597 writing PCM essence).
600 2011-11-30 - bug fixes v1.8.44
601 o Corrected a wrong decryption UL selection when unwrapping MXF.
604 2011-10-27 - bug fixes v1.8.43
605 o Corrected broken Essence UL matching. (Thanks to Michael Loder).
608 2011-08-31 - bug fixes v1.8.42
609 o Added missing HFR support for PCM essence reader/writer.
612 2011-08-30 - bug fixes, enhancements v1.8.41
613 o UL version byte now ignored when comparing UL values.
614 o Changed the version byte in the TimedTextEssence UL to 0x01. There
615 is no published Essence Keys registry so it can't have a maintained
617 o JP2K Sequence Parser modified to skip directory entries that
618 are not files in the case where the parser is initialized with
619 a directory path. When initialized with a list of file names
620 this check is not performed. Based on a hint by Steve Quartly.
621 o Increased the size of the MPEG header parser buffer.
622 o Added missing FrameType() implementation to ASDCP::MPEG2::MXFReader.
623 o Added missing Close() implementations to MXF reader classes.
624 o Added missing Timestamp::Timestamp(const char* datestr) implementation.
625 (Thanks to Matt Sheby for this and the previous three items.)
626 o Fixed error in Kumu::FortunaRNG::FillRandom() that was returning the
627 end of the random buffer instead of the front (Thanks to Mike Radford).
628 o Added support for proposed sound channel format identifiers
629 '7.1DS' and 'WTF'. Optimistically chose version '0x0c'.
630 o Added support for stereoscopic images in JP2K files at edit
631 rates of 48, 50 and 60 eups (96, 100 and 120 fps).
634 2010.11.15 - bug fixes, enhancements v1.7.40
635 o Fixed bug in long KLV packet support (Thanks to Jim Radford).
636 o Fixed AvgBps in PCM files, *again*. Sorry for the crazy.
637 o More fixes and changes in support of 25, 30, 50, 60 fps.
638 (Thanks to Hans K. for the TC rate bug).
639 o Updated KLVFill UL version element to 0x02.
640 o Type change to support Xerces-C 3.x. (Thanks to Matt Sheby).
641 o Some internal API changes to KLV types. Does not affect
643 o Added NetworkLocator type to MXF metadata types.
644 o Added file offset display to klvwalk.
647 2010.09.09 - bug fixes, enhancements, v1.7.39
648 o Fixed bug in JP2K PictureDescriptor initialization in
649 JP2K::MXFReader::OpenRead() and JP2K::MXFSReader::OpenRead()
650 o Once again fiddling with AvgBbs. How can something so simple
651 be such a constant cause of trouble? Tested with 1-, 2- and
652 6-channel input Wav files.
653 o asdcp-test now accepts a directory name when making PCM
654 files (-c). The directory name should be the only filename
655 argument. All files in the directory must be Wav files
656 (mixed channel sizes OK). Files are sorted alphabetically by
657 filename. Hint: use numeric name infix to define order:
666 2010.07.20 - bug fixes, v1.6.37
667 o Fixed TimedTextResourceSubDescriptor UL value.
670 2010.06.16 - bug fixes, v1.6.36
671 o Added support for new Edit Rates to asdcp-test.cpp.
672 o Expanded timed-text file reader in asdcp-test.cpp.
673 o Fixed large BER value encoding (plaintext) and decoding
674 (plaintext and ciphertext). This feature was introduced in
676 o Fixed AvgBps value for multi-channel Wave input.
679 2010.05.13 - bug fixes, enhancements, v1.6.34
680 o ST 429-5 files have corrected ULs for DCTimedTextDescriptor and
681 GenericStream DataElement. Files made with previous versions of
682 the library are incompatible with this and future versions.
683 o Fixed File Package TrackNumber values. Th
685 o Added edit rate constants to AS_DCP.h (25, 30, 50, 60).
686 o Changed AudioDescriptor "SampleRate" element name to "EditRate"
687 to make it consistent with the other types.
688 o Now builds with XercesC 3.x.
689 o KM_memio.h has better const behavior.
690 o Fixed a bug in KM_memio.h string archiving.
693 2010.01.05 - bug fixes, enhancements, v1.5.32
694 o Re-fixed swapped Interop and SMPTE OP Atom UL values. The swap
695 introduced in v1.5.31 was done in error.
696 o Added -z,-Z options to asdcp-test (j2c parameter checking)
697 o Reformed jp2k-test as j2c-test, added help and list processing,
698 added to standard install target.
701 2009.12.31 - bug fixes, enhancements, v1.5.31
702 o Fixed swapped Interop and SMPTE OP Atom UL values.
703 o Added get_BER_length_for_value() subroutine.
704 o Modified ASDCP::h__Writer::WriteEKLVPacket() to allow larger BER
705 lengths for KLV packets larger than 16 MB. This was required to
706 support large font files in the SMPTE 429-5 implementation.
709 2009.11.06 - bug fixes, enhancements, v1.5.29
710 o Fixed a bug that could cause HMAC values to be incorrectly
711 stored in MXF files. Files created with versions of asdcplib
712 prior to this version may have incorrect HMAC values.
713 o Improved handing of XML files for MXF wrapping.
714 o Jpeg2000 codestream EditRate and SampleRate mismatches
715 now warns instead of returning an error.
716 o Improved error handling in Jpeg2000 sequence parsing routines.
717 o Added two methods to Kumu::Timestamp, AddSeconds(), to add (or
718 subtract) seconds to a time value, and GetSecondsSinceEpoch()
719 to get the number of seconds since the unix epoch.
720 o Added new option to asdcp-test, '-a', to specify a UUID when
722 o Added support for specifying the intrinsic duration of MXF files
723 containing timed text.
724 o Added new option to wavesplit, '-i', to display WAV file metadata.
727 2009.05.21 - bug fixes, v.1.4.24
728 o Fixed a bug that caused incorrect SubDescriptors UL values to be
729 written into interop format MXF track files. Note that this involved
730 a substantial reorganization of MXF internals. Please test thoroughly
731 in your application before using in production. Note that this is a
732 significant bug fix and track files created with 1.4.22 may be incompatible
736 2009.04.09 - SMPTE format fixes, enhancements and bug fixes, v.1.4.22
737 o asdcplib now uses GNU autotools on POSIX systems to configure
738 and build. See "./configure" for details. Note that two options,
739 --enable-freedist and --with-python are not enabled in the free
740 version of asdcplib and should not be used.
741 o Added build option (CONFIG_RANDOM_UUID) to enable mixed case UUID
742 generation when environment variable KM_USE_RANDOM_UUID is defined.
743 o Fixed a condition that could cause an error to occur when wrapping
744 SMPTE format timed text track files that do not define a starting
746 o Updated ULs for SMPTE format track files.
747 o SampleRate added to JP2K metadata
748 o Support for wrapping 96kHz WAV files added.
749 o Updated ULs for audio channel formats (ChannelFormat)
750 o Updated font subdescriptor MIME Types for TimedText Trackfiles.
751 o Changed time implementation to support dates beyond Jan 19th, 2038.
752 o Xerces-C XML parser support added.
753 o New build method for Windows (see win32/README.txt for details).
754 o Added new functionality in Kumu to recursively create and delete files
755 and directories, and get free disk space for a given volume path.
756 o Added a method to Kumu::Timestamp, AddMinutes(), to add (or subtract)
757 minutes to a time value.
758 o Improved how Kumu::Timestamp parses timestamps with offsets.
759 o Fixed a bug that caused incorrect HMAC values to be calculated.
762 2008.02.16 - SMPTE format fixes, bug fixes v.1.3.18
763 o Added correct SMPTE UL for StereoscopicPictureSubDescriptor.
764 o Exposed JP2K metadata parser as ParseMetadataIntoDesc().
765 o Added simple stereoscopic framebuffer to support paired ReadFrame()
766 and WriteFrame() methods (allows simpler integration with other
768 o Improved detection of JPEG Interop stereoscopic files.
769 o Win32 build fixes (Thanks to Mike Crowe at DTS).
770 o Added the WITH_MD macro to the makefile. Set this value to one
771 to build Win32 with /MD[d] instead of /MT[d].
772 o The Generic Container UL has been added to the EssenceContainers
773 set in the header partition pack for encrypted files. It has always
774 been there in plaintext files.
775 - Below this point the changes are internal and should not affect you
776 unless you use Kumu directly.
777 o Major refactoring of KM_log.[h|cpp].
778 o Fixed buffer re-sizing issue in Kumu::ByteString.
779 o Replaced type IdentifierList with ArchivableList.
780 o Added COPYING file to the release bundle.
783 2007.12.13 - Bug fixes v.1.2.17
784 o Changed Result_t implementation to use int instead of long, which
785 was causing trouble on some 64 bit platforms.
786 o Fixed EKLV HMAC. NOTE: Breaks backward compatibility with older
787 Interop files. To validate these files, use asdcplib-1.1.14. This
788 should not cause too much trouble since files with broken and
789 non-broken HMAC have been in the wild for years without issue.
790 o Fixed HMAC sequence numbering in encrypted stereoscopic files.
791 o Finished stereoscopic test targets in the makefile.
792 o Fixed the win32 build, now expects VS2005 compiler by default,
793 use WITH_VC6=1 top get VC6 flags.
794 o Stereoscopic and Timed Text modes now have SMPTE UL values.
795 NOTE: SMPTE 429-5 and 429-10 are not yet published. It is possible
796 that these UL values may change before publication. Please use
797 caution when using these features for production work.
798 o Changed a bunch of symbol names in the 429-5 implementation to
799 better match the spec.
800 o Added -U option to asdcp-test to dump the UL library to stdout.
801 o Fixed erroneous placement of the PictureEssenceCoding UL in JP2K
802 files (Interop and SMPTE modes).
805 2007.10.22 - Timed Text, Stereoscopic Picture and Bug fixes v.1.2.16
806 o Significant API changes have been made. Please read all entries
807 in this changelog to be sure you understand the changes. Also
808 note that some changes have been made to LS_MXF_SMPTE files that
809 are incompatible with earlier releases (e.g., EKLV HMAC). If
810 you are looking for a stable interop release, use v.1.1.14.
811 o Fixed RFC 2104 HMAC implementation for LS_MXF_SMPTE only. The
812 broken implementation has been maintained for Interop mode.
813 o Added support for draft SMPTE 429-5 Timed Text Track File. This
814 is still waiting for official SMPTE ULs, so do not use it for
815 shipping products. An XML parser is needed to create a Timed
816 Text Track File; Expat is now an optional part of the build.
817 Make with WITH_XML_PARSER=1 to link with Expat. If you do not
818 link with expat, you will get an error when using the TimedText::
819 DCSubtitleParser class. See also S429-5-cgi.cpp for an example
820 that shows how to serve plaintext MXF file elements directly via
822 o Added support for draft SMPTE 429-10 Stereoscopic Picture Track
823 File, including the JPEG Interop version. This is still waiting
824 for official SMPTE ULs, so do not use it with LS_MXF_SMPTE for
826 o Refactored the following files as a side-effect of the above
827 work: AS_DCP_JP2K.cpp AS_DCP_MPEG2.cpp AS_DCP_PCM.cpp
828 AS_DCP_MXF.cpp AS_DCP_internal.h MXF.[h|cpp] MXFTypes.[h|cpp]
829 Metadata.[h|cpp] h__Reader.cpp h__Writer.cpp klvwalk.cpp.
830 WARNING: While significant effort has been extended to make sure
831 that these changes do not affect existing stable file support,
832 users are cautioned to test this release thouroughly.
833 o Added a large set of filesystem path manglers to KM_fileio.h. See
834 path-test.cpp for example usage. The path manglers have not yet
835 been tested on win32 platforms (they are currently used only by
836 the Timed Text module.
837 o The PathIsFile(), PathIsDirectory() and FileSize() subroutines
838 have been modified to accept const std::string& instead of
840 o Added namespace and parsing support (Expat) to Kumu::XMLElement
841 (currently used only for Timed Text support). Also added some
843 o Altered MXF::UTF16String to use mbtowc() and wctomb().
846 2007.03.31 - Bug fixes v.1.1.14
847 o Fixed KeyFrameOffset value in MPEG wrapping to have negative
848 value. This is probably not yet complete for handling all
849 types of GOPs. Please send chunks of MPEG-2 VES that you
850 find which break this. Thanks to Doremi.
851 ** no other file format changes in this release **
852 o Fixed error in RIP interpretation when reading arbitrary (i.e.,
854 o Fixed a memory leak in ASDCP::MXF::OPAtomHeader when used
855 in read mode. Thanks to Mahesh Bajaj for pointing out this
856 bug and the one above.
857 o Removed asserts from KM_fileio, replaced with RESULT_WRITEFAIL
858 return value statements.
859 o Added -s and -p to the makefile install target.
860 o Altered ByteString behavior to use target Length() in copy
861 operations (instead of Capacity()).
862 o Added new Set() method to ByteString.
863 o Fixed a bug in ByteString::Unarchive() that caused the operation
864 to fail when the buffer was smaller than the read (i.e., when
865 Capacity() was called).
866 o Added IdentifierList class to KM_util.h.
867 o Changed some Error() messages to Debug() in Wav.cpp
868 o Revived jp2k-test.cpp and asdcp-mem-test.cpp (they both had
872 2007.02.15 - Bug fixes v1.1.13
873 o Removed 'VDescObj->SampleRate.Numerator = VDesc.FrameRate;'
874 from MPEG2_VDesc_to_MD() in AS_DCP_MPEG2.cpp, was line 76.
875 o Added KM_TEST_NULL_STR_L() and KM_TEST_NULL_L() macros to
876 KM_log.h. These versions log the location of the null value.
877 Macros are now used in any module that includes KM_log.h.
878 o MPEG2 VES with run of zero values at the head is now OK.
879 o Increased VESHeaderBufSize to 16K.
880 o Added makefile support for local OpenSSL in ../openssl, if
882 o The Kumu::PathIs*() functions now return false if a null or
883 empty string is given (used to be an assert).
884 o Cleaned up the install target in the makefile.
885 o Fixed SMPTE 429-6 HMAC -- FIPS 186-2 implementation was
886 laughably incorrect. Thanks to Doremi for pointing this out.
887 o Removed default parameter to HMACContext::InitKey().
888 o Cleaned up messages and CLI arg handling in asdcp-test.
891 2006.11.19 - Mo better stuff v1.1.12
892 o Changed read-only Result_t accessor methods to const.
893 o Added Base64 (-B) option to kmrandgen.
894 o Removed 16-bit alignment restriction from kmrandgen.
895 o Improved WAV file extraction speed (Thanks to Jim Radford
896 for pointing this out).
897 o Added single-channel split for WAV extraction (asdcp-test -1).
898 o Fixed remainder bug in h__RNG::fill_rand().
901 2006.11.03 - Bug fixes v1.1.11
902 o Increased index table entry list size to 5000.
903 o Added length checking to TLV writer (returns error if TLV
904 payload exceeds 64kB).
905 o Fixed partition header and RIP errors related to 2-partition
906 files (MXF Interop mode).
907 o Added -t option to asdcp-test (SHA-1 digest with Base64 output
909 o Fixed Sub Descriptor reference bug (Thanks to Denis Leconte
910 for dogged determination).
911 o Added directory-of-wav detection to RawEssenceType()
912 o Modified MXF::Partition::AddChildObject() to only generate
913 a UUID if the InstanceID is unset.
914 o Added ComponentMaxRef & ComponentMinRef to RGBAEssenceDescriptor.
916 o Added detection of 2K/4K jp2c, writing correct 4K metadata.
919 2006.10.05 - Bug fixes v1.1.10
920 o Changed RM_RELEASE to RL_RELEASE in MXFTypes.h.
921 o Changed the MXF writer to use RL_RELEASE (was RL_DEVELOPMENT).
922 o Really fixed source reference chain.
923 o Updated JP2K file package label.
924 o Changed location of JPEG2000PictureSubDescriptor in the
925 header (was erroneously before Preface).
926 o Altered LS_MXF_INTEROP to produce 2-partition files.
929 2006.09.25 - Bug fixes v1.1.9
930 o Fixed SourcePackageID value. All files will be 'original',
931 i.e. SourcePackageID will be all zeros. Let me know if you
932 want to set SourcePackageID.
933 o Fixed compiler warnings on some Linux platforms
934 o Fixed the build so that BUILD_DIR is no longer created
936 o Added duration detection to the raw essence parsers. The
937 MPEG parser uses a nasty approximation so don't use it
938 without paying close attention to the result.
939 o Modified PCMParserList to make it more useful as a base
941 o Fixed bugs and re-organized command-line help in asdcp-test
943 o Fixed two-partition file reads.
944 o Fixed Win32 PRNG initialization.
945 o Renamed asdcp-lf-test as kmfilegen.
946 o Added kmrandgen and kmuuidgen.
947 o Added string retrieval mechanism to Result_t.
948 o Refactored Kumu::Identifier and its sub-classes.
949 o Altered Kumu::PathIsFile to return true when the path
950 is a symbolic link (unix only).
951 o Altered Kumu::FileWriter::OpenWrite to use file creation
952 mode 0664 (was 0644) (unix only).
953 o Added Kumu::WriteStringIntoFile() subroutine.
956 2006.04.05 - Bug fixes and new stuff v1.1.7
957 o Fixed a bug in the MPEG parser that caused it to fail when
958 handling start codes spanning buffer boundaries
959 o Added wavesplit and blackwave utility programs
960 o Added support for revised SMPTE HMAC key derivation when
962 o Refactored platform compatibility and general utilities
963 into a new sub-library "Kumu". There are no new build
964 steps or dependencies, but some important things have
966 + Result_t is no longer an enum, it is now a class.
967 Library result codes are now declared as const objects
970 const Kumu::Result_t RESULT_FORMAT (-101, "The file...");
972 The macros ASDCP_SUCCESS and ASDCP_FAILURE still work
973 the same way thanks to an operator overload for type long.
974 See KM_error.h for more information.
975 + The logging interface has been moved out of AS_DCP.h
977 o Some of the command line utilities that were using headers
978 other than AS_DCP.h have been changed to use the Kumu
979 equivalents. If you have code based on those utilities, you
980 will have to update by hand.
981 o Added new types to the EssenceType_t enum.
982 o The guard macro for Win32 code has changed from WIN32 to
986 2006.03.2x - new stuff
987 o Proper handling of stream-id byte of essence UL values
988 o writes 3-partition files, reads 2-part or 3-part
991 2006.03.16 - bug fixes plus
992 o Removed SMPTE_LABELS compile-time option. The reader will now
993 silently accept either SMPTE or MXF Interop labels, the writer
994 can be instructed which to use at runtime. Default is Interop.
995 o Added an AIFF reader. Support is preliminary, it works with the
996 AIFF files I have on hand.
997 o More code refactoring. More to come.
1000 2006.03.09 - full read-write
1001 o Removed ASDCP_WITHOUT_OPENSSL compile-time option.
1002 o Full read/write now working on new MXF library
1005 2005.00.00 - A New Hope
1006 o The temporary mxf-lite has been removed. MXF files are now
1007 managed via the objects in KLV.h, MXFTypes.h MXF.h and
1008 Metadata.h. This release does not support writing MXF files.
1009 o Fixed a header interpretation error in the Wav parser.
1012 2005.00.00 - The Reformation
1013 o Removed mxflib as a dependency by forking the necessary
1014 functions and placing them in the mxf-lite subdirectory.
1015 Please note that the very heavy modifications done here
1016 render all comparisson to mxflib code a substantial task.
1017 All errors are now mine and users are warned not to bug
1018 Oliver or Matt for help with this code. The version of
1019 mxflib at the time of the fork was: 0.5.1.3.
1022 2005.06.03 - bug fixes v0.10.18
1023 o Updated UL batch to include GC UL.
1026 2005.05.27 - bug fixes v0.10.17
1027 o Un-did essence container and compression descriptor changes.
1028 The default build reflects MXF Interop decisions as of 26 May.
1029 o Added note about build versions to README (see above).
1030 o Added warnings to SMPTE_LABELS builds.
1031 o Fixed JP2K essence container label.
1034 2005.05.02 - bug fixes v0.10.16
1035 o Reorganized internal files, added file reader object, added OS
1036 portability header, removed and renamed some files. If you have a
1037 patch against previous versions of the source, you should check
1039 o Added RGBA attributes to JP2K descriptor.
1040 o Changed interface to CodestreamParser.
1041 o Added JP2K parser implementation. It is parsing each frame but is
1042 not yet being used to populate the descriptor.
1043 o Added 48fps option for `asdcp-test -p`.
1044 o Added picture rate constants to AS_DCP.h (23.976, 24, 48).
1045 o Added sample rate constant to AS_DCP.h (48k).
1046 o Changed asdcp-test to encrypt picture headers by default
1047 (plaintext offset will be 0), added -E option to allow
1051 2005.04.28 - bug fixes v0.9.15
1052 o The XML descriptors for the crypto DMS have moved in mxflib to
1053 the file DMS_Crypto.xml (they were in DMS_DCPENC.xml). Older
1054 installations should update the file from mxflib.
1055 o Added Close() and Seek() to ~MyFileWriter(), cleaned up headers
1056 o Added UUID generator output mode (-u).
1057 o Added -S option to extract PCM essence into stereo wav files
1058 o Added more UL testing and conformance checking.
1059 o Added macro SMPTE_LABELS which causes the library to be built
1060 with SMPTE (as opposed to MXF Interop) labels. This is not
1061 set by default, and currently only affects the PCM container
1062 label and encrypted element label.
1063 o Cleaned up the GNUmakefile test targets, the source files
1064 are now named with the TEST_FILE_PREFIX macro.
1065 o enabled 23.976-framed PCM (2002 samples per frame)
1066 o The size of the asdcp-test frame buffer for picture essence
1067 may now be set from the command line (-b). The default is 4MB.
1068 o h__Reader::ReadEKLVPacket() now tests the UL (duh) and switches
1069 on the value, allowing plaintext and ciphertext frames to
1070 be mixed in the file.
1071 o Fixed error in UUID generator format.
1072 o JP2K files now use the GenericPictureDescriptor to store
1073 ContainerDuration and SampleRate. SampleRate is mapped
1074 to EditRate in the PictureDescriptor struct. This fixes
1075 the second caveat from the 0.8.13 release.
1076 o Fxed bug in PCMParserList that was miscalculating the extent
1077 of a PCM sample. This bug did not affect API users, it was
1078 only present in asdcp-test.
1079 o Fixed EditRate on PCM files (was showing sample rate)
1080 o Fixed Encrypted Essence Container UL
1081 o Fixed BlockAlign value for PCM essence
1083 - The following changes were provided by Jeff Loewenguth
1085 o Moved the DMS CryptographicFramework entry from the material
1086 package to the source package
1087 o Fixed erroneous Source Essence Container Label value
1088 o Fixed broken sort of JP2K frames in JP2K parser
1089 o Added FindFrameGOPStart() method to the MPEG2 MXFReader
1090 o Added missing length values for EKLV packets without HMAC
1091 o -x with JP2K essence writes to files with 6 digit names
1093 o The Key ID may now be specified as an argument to asdcp-test
1094 (-j <key-id-string>)
1097 2004.12.30 - bug fixes + wav files v0.8.14
1098 o Added WAV file write to asdcp-test (uses mxflib::waveheader_t).
1099 o Three-partition files reading properly. adscplib still writes
1100 two-partition files.
1101 o Changes in the mxflib WAV essence parser API had broken
1102 asdcplib's ability to read essence from a WAV file. I have
1103 fixed this bug, but at the expense of breaking compatibility
1104 with older versions of mxflib. Beware!
1105 o Removed redundant (but working) bin-text-bin conversions.
1108 2004.12.23 - JPEG 2000 support v0.8.13
1109 o Reads/writes JPEG 2000 essence in plaintext and ciphertext
1110 with the following caveats:
1111 - The Picture Essence Descriptor is empty.
1112 - Because there is no essence descriptor, the reader code
1113 in asdcp-test has no idea how many frames are in the file
1114 and ends with an out-of-bounds frame error. This error
1115 is being suppressed in asdcp-test for the current release.
1116 o Still broken when reading three-partition files.
1119 2004.10.22 - fixes and UL updates v0.7.11
1120 WARNING: COMPATIBILITY BREAKPOINT
1121 Files created with this and future versions of this library are
1122 not compatible with previous versions of this library. As you
1123 might suspect, files created with previous versions of this
1124 library are not compatible with this and future versions.
1126 o h__Reader will now open a three-partitition file (untested)
1127 o Moved DMS from Material partition to File partition
1128 o Added length fields to appropriate places in EKLV packet
1131 2004.10.22 - fixes and UL updates v0.7.10
1132 o fixed frame buffer handling of externally allocated buffer,
1133 created unit test (asdcp-mem-test)
1134 o added operator==() and operator!=() to Rational type
1135 o fixed some type-related compiler warnings
1136 o asdcp-test -p now works on unwrap
1137 o updated some ULs to match documentation (thanks to Arun
1139 o canonicalized line endings
1142 2004.07.02 - full plaintext + ciphertext read/write v0.6.9
1143 o HMAC, plaintext offest and raw ciphertext read supported
1144 o back to proper CBR index
1145 o MPEG temporal offset working
1148 2004.07.01 - plaintext + ciphertext read/write v0.5.8
1149 o encryption of MPEG and PCM essence supported with the
1152 - no plaintext offest support
1153 - no raw ciphertext read support
1154 o moved to reflecting the whole KLV triplet in the CBR
1155 index (now incompatible with mxflib, still searching
1156 for info about what's "right")
1157 o awaitng the following fixes/features:
1158 - retrieve Temporal Offset from index in MPEG2::Reader
1159 - test for correct ULs when reading frame triplets
1160 - fix header metadata items for encrypted files
1162 - plaintext offest support
1163 - raw ciphertext read support
1166 2004.06.14 - plaintext read/write w/key generator v0.4.5
1167 o Project now uses OpenSSL (tested with 0.9.7d on win32, Linux, Darwin)
1168 Use `make ASDCP_WITHOUT_OPENSSL=1` to make plaintext-only version
1169 o Accepts interior I frames when parsing MPEG2 VES
1170 o Improved error reporting on format errors
1171 o Added support for encryption to asdcp-test
1172 o Added RNG for asdcp-test (non-production use only, see notes in FortunaRNG.h)
1173 o Implemented CBC encrypt, decrypt module
1174 o Added partial TemporalOffset retrieval from MPEG2 parser
1175 o Fixed win32 binmode bug
1178 2004.05.12 - plaintext read/write v0.3.4
1179 o Full read/write of plaintext MPEG-2 VES and WAV files
1180 (does not yet support mux from or demux to 2 channel pairs)

1187 o Cleaned up Get/Set naming confusion
1188 o Added missing const qualifiers
1191 2004.04.27 - preview release v0.2.1
1192 o hasty release for quick review
1193 o this release may not build with mxflib using autoconf.
1194 o writes plaintext AS-DCP MPEG2 essence files
1195 o tested under win32 and linux. FreeBSD and Darwin do not work
1198 2004.02.04 - First release (v0.1.1):
1199 o asdcp-test is mostly complete. It should correctly provide
1200 access to the read and info capabilities of the library.
1201 o The MPEG2 reader is functional but not fully tested.
1202 o Some file format integrity tests remain to be coded.
1203 o The PCM reader is mostly complete, I am having difficulty
1204 getting a suitable test file from mxfwrap.
1205 o The makefile creates a static library module. The API
1206 will cleanly support a DSO (or DLL). Let me know if DSO
1207 support is important to you.
1208 o Nothing is thread safe. Thread safety was not a requirement
1209 in the initial project definition. Thread safety may be added
1210 above the mxflib/klvlib level. Let me know if it is important
1212 o The files xmldict.xml and types.xml must be in the current
1213 directory when the program is run. The files are supplied
1214 with mxflib. Runtime location of the files is not currently
1215 a project goal. Comments on how best to handle this situation
1216 would be appreciated. See AS_DCP.cpp at init_mxf_types()
1217 for a more detailed discussion.
