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.
104 asdcp-test - Writes, reads and verifies AS-DCP (MXF) track files.
106 asdcp-wrap - Writes AS-DCP (MXF) track files.
108 asdcp-unwrap - Extracts essence from AS-DCP (MXF) track files.
110 asdcp-info - Displays information about AS-DCP (MXF) track files.
112 asdcp-util - Calculates digests and generates random numbers and UUIDs.
114 as-02-wrap - Writes AS-02 Essence Component files.
116 as-02-unwrap - Extracts essence from AS-02 Essence Component files.
118 kmfilegen - Writes and verifies large files using a platform-
119 independent format. Use it to test issues related to large files.
121 kmuuidgen, kmrandgen - generate UUID values and random numbers.
123 wavesplit - Splits a WAVE file into two or more output files. Used
124 to untangle incorrectly-paired DCDM sound files.
126 blackwave - Write a WAVE file of zeros.
128 pinkwave - Write a WAVE file of SMPTE ST 2095 pink noise.
130 j2c-test - Displays information about JP2K codestreams.
132 Experimental feature: Prototype for High Dynamic Range is a wrapper
133 for the IMF application that allows JPEG-2000 codestreams to be paired
134 with opaque blobs of metadata. AS-02 support must be enabled to
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
149 command-line utilities all respond to -h.
154 2016-12-10 - bug fixes 2.7.18
155 o Fixed *all* Partiton version numbers in AS-02 files (the previous attempt
156 only affected the header partition)
157 o Improved IMSC-1 profile detection. May not yet be perfect, experimentation
159 o Added IMF App2e UL values and new MXF data types ColorPrimary and
160 ThreeColorPrimaries (contributed by Schleich)
161 o Added picture descriptor elements MasteringDisplayPrimaries,
162 MasteringDisplayWhitePointChromaticity, MasteringDisplayMaximumLuminance,
163 and MasteringDisplayMinimumLuminance
164 o Added -o and -O options to as-02-wrap
165 o Fixed as-02-wrap option -p when making 4:4:4 files

169 2016-12-01 - bug fixes 2.6.17
170 o Fixed Partiton and Preface version numbers in AS-02 files
171 o Replaced WIN32 directory scanner with dirent_win.h
172 o The NamespaceURI property of AS-02 timed text files has been exposed in the API
173 and via as-02-wrap -P. This behavior replaces previous bad behavior, but puts
174 responsibility for selecting the correct value on the operator.
175 o Exposed CreatePNGNameId and CreateFontNameId subroutines in AS_02::TimedText
176 o Adjusted UUID generation based on PNG and font names to exclude paths by
177 inserting a call to PathBasename at each Id generation site
178 o Fixed AS-02 timed text index partition
179 o Fixed contents of generic partiton EssenceContainers property in AS-DCP timed
181 o Added PixelLayout to RGBAEssenceDescriptor (contributed by Schleich)
182 o Cleared up MXFGCP1FrameWrappedPictureElement / MXFGCP1FrameWrappedPictureElement
183 ambiguity. PHDR continues to use MXFGCP1FrameWrappedPictureElement.
184 MXFGCI1FrameWrappedPictureElement is supported for interlace.
185 o Added support for 192, 200 and 240 fps images, includes 96, 100 and 120 fpe stereo

189 o Added VideoLineMap property to GenericPictureEssenceDescriptor
190 o Added timed text unwrap support to as-02-unwrap (contributed by Ruppel)
191 o Added prototype PIDM dynamic metadata wrapping, config with --enable-phdr
192 (Not for production use, caveat emptor, not the droids, etc.)
195 2016-08-11 - bug fixes, 2.5.15
197 o Modified as-02-wrap to pass WhiteRefLev, BlackRefLev and ColorRange
198 (contributed by Elmer Musser / Rod Bogart)
199 o Fixed a bug in the index reader that allowed an out-of-bounds vector index
201 o Modified the IndexEntry parser to ignore additional bytes belonging to slice
205 2016-05-06 - bug fixes, 2.5.14
207 o Release 2.5.12 caused two problems with Atoms and DTS-X wrapping that are
208 addressed by this release. The UL values that were changed to correct the
209 DCData (ST 429-14) implementation had two unintended side-effects:
210 1. v2.5.12 cannot read old DCData (and thus DTS-X) track files
211 2. v2.5.12 creates broken Atmos track files (incorrect ULs)
212 The fix for this involved the following changes:
213 1. ASDCP::DCData::(MXFReader|MXFWriter) are no longer base classes of
214 ASDCP::ATMOS::(MXFReader|MXFWriter).
215 2. New UL values have been added to carry the original Atoms UL values:
216 a. DolbyAtmosDCDataWrappingFrame
217 b. DolbyAtmosDCDataEssence
218 c. DolbyAtmosDCDataDescriptor
219 3. ASDCP::ATMOS::(MXFReader|MXFWriter) have been modified to use the
220 DolbyAtmosDCData* UL values.
221 4. ASDCP::DCData::MXFReader will parse files having either DCData* or
222 DolbyAtmosDCData* UL values.
223 5. ASDCP::DCData:: MXFWriter continues to use DCData* UL values from ST
225 o Some optional parameters of the MXF metadata packs were being erroneously
226 initialized with a value of zero (0), such as GenericPictureEssenceDescriptor
227 ::SignalStandard, GenericPictureEssenceDescriptor::SampledXOffset(0), etc.
228 o Added higher edit rates (96, 100, 120) to the cinema TimedText_Parser
230 o Defined bool ASDCP::UL::operator<(const UL& rhs) const, which is needed to
231 carry out the version-insensitive lookup policy when searching for ULs in a
232 std::map<> of UL entries.
233 o New files: src/info.in src/CMakeLists.txt
234 o Removed filess: AS_DCP_DCData_internal.h
237 2016-03-17 - bug fixes, 2.5.12
238 o Changed default UNIX file permissions to "666"
239 o Changed default UNIX file permissions to "777"

244 o Fixed the version byte in UL DataEssenceCoding
245 o Fixed duplicate linkage error for symbol MIME2str
246 o Big patch from Wolfgang Ruppel:
247 o Corrected erroneous fixed-tag values in ActiveHeight, ActiveWidth,
248 ActiveXOffset, ActiveYOffset UL definitions.
249 o Provided a stub implementation for Kumu::DirScannerEx (A real
250 implementation will follow soon.)
251 o Added as-02-info program
252 o Added Seek() method to PCM parsers
253 o Added CMakeLists.txt
256 2015-11-10 - bug fixes, IMF text, pink noise, 2.5.11
257 o I moved personal dev environment from older gcc to newer clang. Many
258 small changes were made to satisfy the new compiler:
259 - Altered many printf format codes to use the correct format for the
261 - Parenthesized some expressions to clarify previously ambiguous
262 expectation about precedence.
263 - Created macro KM_MACOSX for use in OS-specific code selection.
264 - Removed last uses of the old C-language abs(), now using Kumu::xabs().
265 - Removed last uses of the old C-language atoi(), not using strtol().
266 o Added platform-independent call Kumu::GetExecutablePath() (to be tested
268 o Added new capabilities to Result_t.
269 o Added imlementation of SMPTE ST 2092-1 pink noise generator.
270 o Added pinkwave CLI utility.
271 o Added font support to the IMF timed-text wrapper.
272 o Fixed a bug that was causing Array properties to be written without
273 the (count, length) header (from PAL).
274 o General review of Batch/Array distinction throughout the project.
275 o Cleaned up definitions of optional properties in all MXF metadata packs.
276 o Fixed Win32 build (from Crowe).
277 o Fixed a bug that caused incorrect failure when parsing JPEG 2000
278 codestreams having fewer than five decomposition levels. (from Korneder).
279 o Fixed missing UUID generation in some instances of the MCALinkID property.
280 o Added -w option to asdcp-wrap to support use of WTF label with MCA.
281 o Altered asdcp-wrap to recognize "-C <UL>" when MCA is being used.
282 o Fixed broken -A <w>/<h> option in as-02-wrap and phdr-wrap.
283 o asdcp-wrap and as-02-wrap now allow split channel groups in MCA labels.
286 2015-02-23 - bug fixes, 2.4.10
287 o Fixed a new bug introduced by the fix to large numbers of subtitle ancillary
289 o Added support for generic Aux Data (ST 429-14) to asdcp-wrap.
292 2015-02-19 - PHDR feature, bug fixes, 2.4.9
293 o Modified PCMParser and PCMParserList to return partial frame buffers at the
294 end of a WAV input file. This was needed to allow wrapping all samples into
295 an AS-02 audio file (which is clip-wrapped) in the case where the input file
296 has an odd number of samples with respect to the frame buffer size being
297 used. If there is more than one input file the length of the last buffer
298 will be determined by PCMParserList to be the shortest of the input files.
299 Prior to this change, partial samples in an input WAV file have been
300 abandoned (i.e., not written out to the MXF file). As a result, AS-DCP
301 applications will have to decide whether to abandon the partial last frame
302 (usually detected by testing frame_buffer.Size() != frame_buffer.Capacity())
303 or write it to the MXF file. Programs written to the old API will write the
304 partial frame (i.e., new behavior.) This should not be harmful since the
305 remainder of the buffer is zeroed and the output file will contain one
306 additional edit unit compared to the previous version.
307 o asdcp-wrap has been modified to test for the partial buffer and by default
308 will complain and abandon the buffer (i.e., same behavior but with a warning
309 message.) A new command line switch (-g) alters this behavior and writes
310 the buffer to the MXF file (it still warns the user that this condition is
312 o as-02-wrap now wraps all samples from the input file to the MXF file. There
313 is no padding, the clip is exactly the set of samples from the input.
314 o as-02 unwrap is temporarily restricted to creating wav files that are
315 aligned with the frame buffer size. This means that the output file will
316 be longer than the original WAV input in the case where the input file has
317 an odd number of samples with respect to the frame buffer size being used.
318 The pad samples are zero (silence).
319 o Modified CalcFramesFromDurationInSamples() to increment the count by one for
320 the case where the input file has an odd number of samples with respect to
321 the frame buffer size being used (previously it truncated the odd samples.)
322 o Fixed ST 429-5 / ST 2067-5 wrapping to increase header space when ancillary
323 resources are present (fixes a bug that cause the header to overflow the
324 allotted space when large numbers of PNG files were present.)
325 o Refactored GetXMLDocType() to use the XML parser.
326 o Added ParseFirstFromString() method to Kumu::XMLElement
327 o Removed Kumu::StringIsXML from the API.
328 o Added ASDCP::MXF::RGBALayout type
329 o Added J2CLayout property to JPEG2000PictureSubDescriptor
330 o Changed km_token_split() to retain empty elements in the output list
331 o Added PHDR wrapping for AS-02.
332 o Added J2CLayout property to the JPEG2000PictureSubDescriptor. This
333 support is preliminary: the Raw data type is being used instead of
334 RGBALayout type, which will be in the next release.
337 2014-10-2 - Bug fixes and enhancements, 2.2.6
338 o Fixed erroneous 377-4 MCA identifier in AS_DCP_PCM dump routine
339 o Fixed erroneous byte 13 in

350 o cleaned up use of atoi() in the library
353 2014-07-09 - Additional IMF/AS-02 support, bug fixes and enhancements, 2.1.4
354 o Added IMF App 2 edit rates in AS_02 namespace: EditRate_29_97,
356 o Revised AEC CBC context objects to copy the key rather than
357 keep the reference passed in to it.
358 o Addressed a bug that would allow unimpeded iteration of component
359 values in a JP2K::PictureDescriptor object.
360 o Addressed a bug that was incorrectly recording the sequence Duration
361 in MXF Track objects.
362 o Added ASDCP::AtmosSyncChannelMixer::AppendSilenceChannels()
363 o Added a QCD decoder to the j2c parser.
364 o Altered ASDCP::KLVPacket::HasUL() to use version-blind matching.
365 o Fixed an uninitialized variable in MemIOReader::ReadString() that
366 caused unbounded reads.
367 o Fixed broken ByteString::ArchiveLength() method
368 o Fixed broken version numbers on SoundfieldGroupLinkID and
369 GroupOfSoundfieldGroupsLinkID UL values.
370 o Added DBOXMotionCodePrimaryStream and DBOXMotionCodeSecondaryStream UL
371 values to the internal dictionary.
372 o Added optional prefix handling to MCA label generator.
373 o Re-factored MCA label generator to include additional
374 metadata (Thanks to Mike Radford).
375 o Added new options to as-02-wrap.
378 2014-01-06 – Additional IMF/AS-02 support, bug fixes 2.1.1
379 o Fixed missing-index-partion bugs for AS-02 files.
380 o Moved LocalFilenameResolver into the AS_DCP public API so that it
381 can be used by other modules including AS-02.
382 o Did further refactoring of AS-02 Writer classes to separate CBR
383 and VBR indexing implementations.
384 o Fixed wave wrapping UL in clip-wrapped AS-02 files. Renamed some
385 UL constants to reflect "clip" or "frame" wrapping.
386 o Re-factored JP2K_PDesc_to_MD() and MD_to_JP2K_PDesc() to work
387 with GenericPictureEssenceDescriptor objects.
388 o Fixed a bug that was suppressing PictureComponentSizing,
389 CodingStyleDefault and QuantizationDefault when writing the
390 essence descriptor in a JP2K file (AS-DCP and AS-02).
391 o Fixed the version byte on the following UL values:
392 StereoscopicPictureSubDescriptor
393 GenericPictureEssenceDescriptor_ColorPrimaries
394 GenericPictureEssenceDescriptor_ActiveHeight
395 GenericPictureEssenceDescriptor_ActiveWidth
396 GenericPictureEssenceDescriptor_ActiveXOffset
397 GenericPictureEssenceDescriptor_ActiveYOffset
398 o Added some essence descriptor options to as-02-wrap.
399 o Changed bit rate display in asdcp-info from mebi-bits/s to
401 o Added "SMPTE" / "Interop" format type display to asdcp-info.
402 o Improved integration of ST 377-4 MCA concepts with ST 429-2 static
404 o Modified asdcp-wrap to assume -L when wrapping timed-text (since
405 there is no MXF text wrapping for Interop.)
406 o Added new EssenceType_t values for IMF/AS-02 track files.
407 o Added detection for AS-02 track files to ASDCP::EssenceType()
408 o Changed lots of "const char*" to "const std::string&" in the

414 (thanks to both Kristof Provost and Franck Chopin)
415 o Fixed broken sample alignment in RF64Writer (thanks to Wolfgang
417 o Fixed win32 build (thanks to Dolby)
418 o fixed a bug that caused blackwave to only produce 96kHz WAV files.
419 (thanks to Stephane W)
422 2013-07-02 – IMF/AS-02 support, bug fixes 2.0.0
423 o Massive refactoring of internals to allow easier implementation
424 of AS-02. Some API changes were made as well (note that
425 OPAtomHeader is now OP1aHeader and RIP is no longer part of the
426 OP1aHeader.) If you are using this project as a library (and
427 especially if you are keeping patches against it) PLEASE TAKE
428 TIME TO EVALUATE THIS RELEASE THOUROUGHLY BEFORE ADDING IT TO
430 o Final integration of Fraunhoffer IIS code contribution. AS-02
431 files are now fully supported with some TODOs and two major
432 exceptions: LEAD indexes are not supported by the MXF writers
433 and interlace images are not yet supported.
434 o Added support for MCA labels (ST 428-12) to asdcp-wrap. Note
435 that this project is still in the early stages of interop testing
436 so errors are likely present and don't expect any server to
437 make use of this feature.

458 2013-02-20 - bug fixes, enhancements 1.10.48
459 o Refactored internals of the AS-DCP file readers. While no
460 changes in behavior are intended, users are cautioned to test
461 thouroughly before use in production.
462 o Fixed a bug in ReadAncillaryResource that was causing bogus HMAC
463 failures when reading resources from a file.
464 o Fixed premature-release bug in the Expat version of the XML parser.
465 Thanks to Carsten Feldheim (IIS) for the tip.
466 o Fixed -W option in asdcp-unwrap. Thanks to RGB.
467 o Added P-HFR support to asdcp-wrap (see URL for details:
468 http://isdcf.com/papers/ISDCF-HighFrameRate-DCP.pdf).
469 o Added support for SMPTE ST 428-21 "Archival Frame Rates".

472 o Added support for 96 kHz files to blackwave.
473 o Added new path and string manglers to Kumu.
474 o Updated MCA ULs (I warned you...). Again please take some
475 time to proof this work against ST 477-4 including the latest
476 drafts of the registries.
477 Changed the version byte (8 0f 16) to 0x0e:
478 MCALabelSubDescriptor
479 AudioChannelLabelSubDescriptor
480 SoundfieldGroupLabelSubDescriptor
481 GroupOfSoundfieldGroupsLabelSubDescriptor
482 GroupOfSoundfieldGroupsLinkID
483 Changed bytes 8 and and 13 of SoundfieldGroupLinkID

496 o Added missing zero-initializers to time values when parsing a
497 timestamp string (in the case where the optional [Thh:mm.[:ss]]
498 syntax is not present in an encoded string).
500 2012-03-06 - bug fixes, enhancements 1.9.45
501 o Removed ASDCP::Timestamp, all items that were of that class are now
502 of class Kumu::Timestamp
503 o Refactored Kumu::Timestamp to use KM_tai for internal representation
504 (replaced public Y M D, h, m, s variables)
505 o Refactored Kumu::Timestamp to use KM_tai for WIN32 builds
506 o Added UTC offset awareness to Kumu::Timestamp
507 o Replaced "long GetSecondsSinceEpoch(void) const" with
508 "ui64_t GetCTime() const"
509 o Corrected UL version segment in "7.1 DS" and "WTF" audio format
510 labels (corresponds with publication of ST 429-2:2011).
511 o Exposed MXF object interface (MXF.h, Metadata.h) via ASDCP MXFReader
512 and MXFWriter classes.
513 o Added UL values from ST 377-4:2012. >>>>NOTE: These are preliminary
514 values, subject to change upon final publication of not only ST 377-4
515 but also the relevant registries. This is a good time to compare them
516 to the standard and complain if you think they are wrong!
517 o Added MCALabelSubDescriptor, AudioChannelLabelSubDescriptor,
518 SoundfieldGroupLabelSubDescriptor, and
519 GroupOfSoundfieldGroupsLabelSubDescriptor (from ST 377-4:2012) to
521 o Changed some internals to make MXFWriter::OPAtomHeader() work correctly.
522 o Split asdcp-test into several different programs to help relieve
523 the impenetrable-list-of-arguments problem. asdcp-wrap, asdcp-unwrap
524 and asdcp-info take the place of asdcp-test's -c, -x and -i options,
525 respectively. asdcp-util contains the remaining functions. Note that
526 asdcp-test is now DEPRECATED, new functionality and bug fixes will be
527 aimed at the new tools. Also note that some options and calling
528 conventions are different for the new tools as compared to asdcp-test.
529 Please read the synopses and make sure you understand the new idioms.
530 o asdcp-wrap has a new argument, -C <UL>, that writes the given UL to the
531 ChannelAssignment item in the WaveAudioDescriptor (only useful when
532 writing PCM essence).
535 2011-11-30 - bug fixes v1.8.44
536 o Corrected a wrong decryption UL selection when unwrapping MXF.
539 2011-10-27 - bug fixes v1.8.43
540 o Corrected broken Essence UL matching. (Thanks to Michael Loder).
543 2011-08-31 - bug fixes v1.8.42
544 o Added missing HFR support for PCM essence reader/writer.
547 2011-08-30 - bug fixes, enhancements v1.8.41
548 o UL version byte now ignored when comparing UL values.
549 o Changed the version byte in the TimedTextEssence UL to 0x01. There
550 is no published Essence Keys registry so it can't have a maintained
552 o JP2K Sequence Parser modified to skip directory entries that
553 are not files in the case where the parser is initialized with
554 a directory path. When initialized with a list of file names
555 this check is not performed. Based on a hint by Steve Quartly.
556 o Increased the size of the MPEG header parser buffer.
557 o Added missing FrameType() implementation to ASDCP::MPEG2::MXFReader.
558 o Added missing Close() implementations to MXF reader classes.
559 o Added missing Timestamp::Timestamp(const char* datestr) implementation.
560 (Thanks to Matt Sheby for this and the previous three items.)
561 o Fixed error in Kumu::FortunaRNG::FillRandom() that was returning the
562 end of the random buffer instead of the front (Thanks to Mike Radford).
563 o Added support for proposed sound channel format identifiers
564 '7.1DS' and 'WTF'. Optimistically chose version '0x0c'.
565 o Added support for stereoscopic images in JP2K files at edit
566 rates of 48, 50 and 60 eups (96, 100 and 120 fps).
569 2010.11.15 - bug fixes, enhancements v1.7.40
570 o Fixed bug in long KLV packet support (Thanks to Jim Radford).
571 o Fixed AvgBps in PCM files, *again*. Sorry for the crazy.
572 o More fixes and changes in support of 25, 30, 50, 60 fps.
573 (Thanks to Hans K. for the TC rate bug).
574 o Updated KLVFill UL version element to 0x02.
575 o Type change to support Xerces-C 3.x. (Thanks to Matt Sheby).
576 o Some internal API changes to KLV types. Does not affect
578 o Added NetworkLocator type to MXF metadata types.
579 o Added file offset display to klvwalk.
582 2010.09.09 - bug fixes, enhancements, v1.7.39
583 o Fixed bug in JP2K PictureDescriptor initialization in
584 JP2K::MXFReader::OpenRead() and JP2K::MXFSReader::OpenRead()
585 o Once again fiddling with AvgBbs. How can something so simple
586 be such a constant cause of trouble? Tested with 1-, 2- and
587 6-channel input Wav files.
588 o asdcp-test now accepts a directory name when making PCM
589 files (-c). The directory name should be the only filename
590 argument. All files in the directory must be Wav files
591 (mixed channel sizes OK). Files are sorted alphabetically by
592 filename. Hint: use numeric name infix to define order:
601 2010.07.20 - bug fixes, v1.6.37
602 o Fixed TimedTextResourceSubDescriptor UL value.
605 2010.06.16 - bug fixes, v1.6.36
606 o Added support for new Edit Rates to asdcp-test.cpp.
607 o Expanded timed-text file reader in asdcp-test.cpp.
608 o Fixed large BER value encoding (plaintext) and decoding
609 (plaintext and ciphertext). This feature was introduced in
611 o Fixed AvgBps value for multi-channel Wave input.
614 2010.05.13 - bug fixes, enhancements, v1.6.34
615 o ST 429-5 files have corrected ULs for DCTimedTextDescriptor and
616 GenericStream DataElement. Files made with previous versions of
617 the library are incompatible with this and future versions.
618 o Fixed File Package TrackNumber values. Th
620 o Added edit rate constants to AS_DCP.h (25, 30, 50, 60).
621 o Changed AudioDescriptor "SampleRate" element name to "EditRate"
622 to make it consistent with the other types.
623 o Now builds with XercesC 3.x.
624 o KM_memio.h has better const behavior.
625 o Fixed a bug in KM_memio.h string archiving.
628 2010.01.05 - bug fixes, enhancements, v1.5.32
629 o Re-fixed swapped Interop and SMPTE OP Atom UL values. The swap
630 introduced in v1.5.31 was done in error.
631 o Added -z,-Z options to asdcp-test (j2c parameter checking)
632 o Reformed jp2k-test as j2c-test, added help and list processing,
633 added to standard install target.
636 2009.12.31 - bug fixes, enhancements, v1.5.31
637 o Fixed swapped Interop and SMPTE OP Atom UL values.
638 o Added get_BER_length_for_value() subroutine.
639 o Modified ASDCP::h__Writer::WriteEKLVPacket() to allow larger BER
640 lengths for KLV packets larger than 16 MB. This was required to
641 support large font files in the SMPTE 429-5 implementation.
644 2009.11.06 - bug fixes, enhancements, v1.5.29
645 o Fixed a bug that could cause HMAC values to be incorrectly
646 stored in MXF files. Files created with versions of asdcplib
647 prior to this version may have incorrect HMAC values.
648 o Improved handing of XML files for MXF wrapping.
649 o Jpeg2000 codestream EditRate and SampleRate mismatches
650 now warns instead of returning an error.
651 o Improved error handling in Jpeg2000 sequence parsing routines.
652 o Added two methods to Kumu::Timestamp, AddSeconds(), to add (or
653 subtract) seconds to a time value, and GetSecondsSinceEpoch()
654 to get the number of seconds since the unix epoch.
655 o Added new option to asdcp-test, '-a', to specify a UUID when
657 o Added support for specifying the intrinsic duration of MXF files
658 containing timed text.
659 o Added new option to wavesplit, '-i', to display WAV file metadata.
662 2009.05.21 - bug fixes, v.1.4.24
663 o Fixed a bug that caused incorrect SubDescriptors UL values to be
664 written into interop format MXF track files. Note that this involved
665 a substantial reorganization of MXF internals. Please test thoroughly
666 in your application before using in production. Note that this is a
667 significant bug fix and track files created with 1.4.22 may be incompatible
671 2009.04.09 - SMPTE format fixes, enhancements and bug fixes, v.1.4.22
672 o asdcplib now uses GNU autotools on POSIX systems to configure
673 and build. See "./configure" for details. Note that two options,
674 --enable-freedist and --with-python are not enabled in the free
675 version of asdcplib and should not be used.
676 o Added build option (CONFIG_RANDOM_UUID) to enable mixed case UUID
677 generation when environment variable KM_USE_RANDOM_UUID is defined.
678 o Fixed a condition that could cause an error to occur when wrapping
679 SMPTE format timed text track files that do not define a starting
681 o Updated ULs for SMPTE format track files.
682 o SampleRate added to JP2K metadata
683 o Support for wrapping 96kHz WAV files added.
684 o Updated ULs for audio channel formats (ChannelFormat)
685 o Updated font subdescriptor MIME Types for TimedText Trackfiles.
686 o Changed time implementation to support dates beyond Jan 19th, 2038.
687 o Xerces-C XML parser support added.
688 o New build method for Windows (see win32/README.txt for details).
689 o Added new functionality in Kumu to recursively create and delete files
690 and directories, and get free disk space for a given volume path.
691 o Added a method to Kumu::Timestamp, AddMinutes(), to add (or subtract)
692 minutes to a time value.
693 o Improved how Kumu::Timestamp parses timestamps with offsets.
694 o Fixed a bug that caused incorrect HMAC values to be calculated.
697 2008.02.16 - SMPTE format fixes, bug fixes v.1.3.18
698 o Added correct SMPTE UL for StereoscopicPictureSubDescriptor.
699 o Exposed JP2K metadata parser as ParseMetadataIntoDesc().
700 o Added simple stereoscopic framebuffer to support paired ReadFrame()
701 and WriteFrame() methods (allows simpler integration with other
703 o Improved detection of JPEG Interop stereoscopic files.
704 o Win32 build fixes (Thanks to Mike Crowe at DTS).
705 o Added the WITH_MD macro to the makefile. Set this value to one
706 to build Win32 with /MD[d] instead of /MT[d].
707 o The Generic Container UL has been added to the EssenceContainers
708 set in the header partition pack for encrypted files. It has always
709 been there in plaintext files.
710 - Below this point the changes are internal and should not affect you
711 unless you use Kumu directly.
712 o Major refactoring of KM_log.[h|cpp].
713 o Fixed buffer re-sizing issue in Kumu::ByteString.
714 o Replaced type IdentifierList with ArchivableList.
715 o Added COPYING file to the release bundle.
718 2007.12.13 - Bug fixes v.1.2.17
719 o Changed Result_t implementation to use int instead of long, which
720 was causing trouble on some 64 bit platforms.
721 o Fixed EKLV HMAC. NOTE: Breaks backward compatibility with older
722 Interop files. To validate these files, use asdcplib-1.1.14. This
723 should not cause too much trouble since files with broken and
724 non-broken HMAC have been in the wild for years without issue.
725 o Fixed HMAC sequence numbering in encrypted stereoscopic files.
726 o Finished stereoscopic test targets in the makefile.
727 o Fixed the win32 build, now expects VS2005 compiler by default,
728 use WITH_VC6=1 top get VC6 flags.
729 o Stereoscopic and Timed Text modes now have SMPTE UL values.
730 NOTE: SMPTE 429-5 and 429-10 are not yet published. It is possible
731 that these UL values may change before publication. Please use
732 caution when using these features for production work.
733 o Changed a bunch of symbol names in the 429-5 implementation to
734 better match the spec.
735 o Added -U option to asdcp-test to dump the UL library to stdout.
736 o Fixed erroneous placement of the PictureEssenceCoding UL in JP2K
737 files (Interop and SMPTE modes).
740 2007.10.22 - Timed Text, Stereoscopic Picture and Bug fixes v.1.2.16
741 o Significant API changes have been made. Please read all entries
742 in this changelog to be sure you understand the changes. Also
743 note that some changes have been made to LS_MXF_SMPTE files that
744 are incompatible with earlier releases (e.g., EKLV HMAC). If
745 you are looking for a stable interop release, use v.1.1.14.
746 o Fixed RFC 2104 HMAC implementation for LS_MXF_SMPTE only. The
747 broken implementation has been maintained for Interop mode.
748 o Added support for draft SMPTE 429-5 Timed Text Track File. This
749 is still waiting for official SMPTE ULs, so do not use it for
750 shipping products. An XML parser is needed to create a Timed
751 Text Track File; Expat is now an optional part of the build.
752 Make with WITH_XML_PARSER=1 to link with Expat. If you do not
753 link with expat, you will get an error when using the TimedText::
754 DCSubtitleParser class. See also S429-5-cgi.cpp for an example
755 that shows how to serve plaintext MXF file elements directly via
757 o Added support for draft SMPTE 429-10 Stereoscopic Picture Track
758 File, including the JPEG Interop version. This is still waiting
759 for official SMPTE ULs, so do not use it with LS_MXF_SMPTE for
761 o Refactored the following files as a side-effect of the above
762 work: AS_DCP_JP2K.cpp AS_DCP_MPEG2.cpp AS_DCP_PCM.cpp
763 AS_DCP_MXF.cpp AS_DCP_internal.h MXF.[h|cpp] MXFTypes.[h|cpp]
764 Metadata.[h|cpp] h__Reader.cpp h__Writer.cpp klvwalk.cpp.
765 WARNING: While significant effort has been extended to make sure
766 that these changes do not affect existing stable file support,
767 users are cautioned to test this release thouroughly.
768 o Added a large set of filesystem path manglers to KM_fileio.h. See
769 path-test.cpp for example usage. The path manglers have not yet
770 been tested on win32 platforms (they are currently used only by
771 the Timed Text module.
772 o The PathIsFile(), PathIsDirectory() and FileSize() subroutines
773 have been modified to accept const std::string& instead of
775 o Added namespace and parsing support (Expat) to Kumu::XMLElement
776 (currently used only for Timed Text support). Also added some
778 o Altered MXF::UTF16String to use mbtowc() and wctomb().
781 2007.03.31 - Bug fixes v.1.1.14
782 o Fixed KeyFrameOffset value in MPEG wrapping to have negative
783 value. This is probably not yet complete for handling all
784 types of GOPs. Please send chunks of MPEG-2 VES that you
785 find which break this. Thanks to Doremi.
786 ** no other file format changes in this release **
787 o Fixed error in RIP interpretation when reading arbitrary (i.e.,
789 o Fixed a memory leak in ASDCP::MXF::OPAtomHeader when used
790 in read mode. Thanks to Mahesh Bajaj for pointing out this
791 bug and the one above.
792 o Removed asserts from KM_fileio, replaced with RESULT_WRITEFAIL
793 return value statements.
794 o Added -s and -p to the makefile install target.
795 o Altered ByteString behavior to use target Length() in copy
796 operations (instead of Capacity()).
797 o Added new Set() method to ByteString.
798 o Fixed a bug in ByteString::Unarchive() that caused the operation
799 to fail when the buffer was smaller than the read (i.e., when
800 Capacity() was called).
801 o Added IdentifierList class to KM_util.h.
802 o Changed some Error() messages to Debug() in Wav.cpp
803 o Revived jp2k-test.cpp and asdcp-mem-test.cpp (they both had
807 2007.02.15 - Bug fixes v1.1.13
808 o Removed 'VDescObj->SampleRate.Numerator = VDesc.FrameRate;'
809 from MPEG2_VDesc_to_MD() in AS_DCP_MPEG2.cpp, was line 76.
810 o Added KM_TEST_NULL_STR_L() and KM_TEST_NULL_L() macros to
811 KM_log.h. These versions log the location of the null value.
812 Macros are now used in any module that includes KM_log.h.
813 o MPEG2 VES with run of zero values at the head is now OK.
814 o Increased VESHeaderBufSize to 16K.
815 o Added makefile support for local OpenSSL in ../openssl, if
817 o The Kumu::PathIs*() functions now return false if a null or
818 empty string is given (used to be an assert).
819 o Cleaned up the install target in the makefile.
820 o Fixed SMPTE 429-6 HMAC -- FIPS 186-2 implementation was
821 laughably incorrect. Thanks to Doremi for pointing this out.
822 o Removed default parameter to HMACContext::InitKey().
823 o Cleaned up messages and CLI arg handling in asdcp-test.
826 2006.11.19 - Mo better stuff v1.1.12
827 o Changed read-only Result_t accessor methods to const.
828 o Added Base64 (-B) option to kmrandgen.
829 o Removed 16-bit alignment restriction from kmrandgen.
830 o Improved WAV file extraction speed (Thanks to Jim Radford
831 for pointing this out).
832 o Added single-channel split for WAV extraction (asdcp-test -1).
833 o Fixed remainder bug in h__RNG::fill_rand().
836 2006.11.03 - Bug fixes v1.1.11
837 o Increased index table entry list size to 5000.
838 o Added length checking to TLV writer (returns error if TLV
839 payload exceeds 64kB).
840 o Fixed partition header and RIP errors related to 2-partition
841 files (MXF Interop mode).
842 o Added -t option to asdcp-test (SHA-1 digest with Base64 output
844 o Fixed Sub Descriptor reference bug (Thanks to Denis Leconte
845 for dogged determination).
846 o Added directory-of-wav detection to RawEssenceType()
847 o Modified MXF::Partition::AddChildObject() to only generate
848 a UUID if the InstanceID is unset.
849 o Added ComponentMaxRef & ComponentMinRef to RGBAEssenceDescriptor.
851 o Added detection of 2K/4K jp2c, writing correct 4K metadata.
854 2006.10.05 - Bug fixes v1.1.10
855 o Changed RM_RELEASE to RL_RELEASE in MXFTypes.h.
856 o Changed the MXF writer to use RL_RELEASE (was RL_DEVELOPMENT).
857 o Really fixed source reference chain.
858 o Updated JP2K file package label.
859 o Changed location of JPEG2000PictureSubDescriptor in the
860 header (was erroneously before Preface).
861 o Altered LS_MXF_INTEROP to produce 2-partition files.
864 2006.09.25 - Bug fixes v1.1.9
865 o Fixed SourcePackageID value. All files will be 'original',
866 i.e. SourcePackageID will be all zeros. Let me know if you
867 want to set SourcePackageID.
868 o Fixed compiler warnings on some Linux platforms
869 o Fixed the build so that BUILD_DIR is no longer created
871 o Added duration detection to the raw essence parsers. The
872 MPEG parser uses a nasty approximation so don't use it
873 without paying close attention to the result.
874 o Modified PCMParserList to make it more useful as a base
876 o Fixed bugs and re-organized command-line help in asdcp-test
878 o Fixed two-partition file reads.
879 o Fixed Win32 PRNG initialization.
880 o Renamed asdcp-lf-test as kmfilegen.
881 o Added kmrandgen and kmuuidgen.
882 o Added string retrieval mechanism to Result_t.
883 o Refactored Kumu::Identifier and its sub-classes.
884 o Altered Kumu::PathIsFile to return true when the path
885 is a symbolic link (unix only).
886 o Altered Kumu::FileWriter::OpenWrite to use file creation
887 mode 0664 (was 0644) (unix only).
888 o Added Kumu::WriteStringIntoFile() subroutine.
891 2006.04.05 - Bug fixes and new stuff v1.1.7
892 o Fixed a bug in the MPEG parser that caused it to fail when
893 handling start codes spanning buffer boundaries
894 o Added wavesplit and blackwave utility programs
895 o Added support for revised SMPTE HMAC key derivation when
897 o Refactored platform compatibility and general utilities
898 into a new sub-library "Kumu". There are no new build
899 steps or dependencies, but some important things have
901 + Result_t is no longer an enum, it is now a class.
902 Library result codes are now declared as const objects
905 const Kumu::Result_t RESULT_FORMAT (-101, "The file...");
907 The macros ASDCP_SUCCESS and ASDCP_FAILURE still work
908 the same way thanks to an operator overload for type long.
909 See KM_error.h for more information.
910 + The logging interface has been moved out of AS_DCP.h
912 o Some of the command line utilities that were using headers
913 other than AS_DCP.h have been changed to use the Kumu
914 equivalents. If you have code based on those utilities, you
915 will have to update by hand.
916 o Added new types to the EssenceType_t enum.
917 o The guard macro for Win32 code has changed from WIN32 to
921 2006.03.2x - new stuff
922 o Proper handling of stream-id byte of essence UL values
923 o writes 3-partition files, reads 2-part or 3-part
926 2006.03.16 - bug fixes plus
927 o Removed SMPTE_LABELS compile-time option. The reader will now
928 silently accept either SMPTE or MXF Interop labels, the writer
929 can be instructed which to use at runtime. Default is Interop.
930 o Added an AIFF reader. Support is preliminary, it works with the
931 AIFF files I have on hand.
932 o More code refactoring. More to come.
935 2006.03.09 - full read-write
936 o Removed ASDCP_WITHOUT_OPENSSL compile-time option.
937 o Full read/write now working on new MXF library
940 2005.00.00 - A New Hope
941 o The temporary mxf-lite has been removed. MXF files are now
942 managed via the objects in KLV.h, MXFTypes.h MXF.h and
943 Metadata.h. This release does not support writing MXF files.
944 o Fixed a header interpretation error in the Wav parser.
947 2005.00.00 - The Reformation
948 o Removed mxflib as a dependency by forking the necessary
949 functions and placing them in the mxf-lite subdirectory.
950 Please note that the very heavy modifications done here
951 render all comparisson to mxflib code a substantial task.
952 All errors are now mine and users are warned not to bug
953 Oliver or Matt for help with this code. The version of
954 mxflib at the time of the fork was: 0.5.1.3.
957 2005.06.03 - bug fixes v0.10.18
958 o Updated UL batch to include GC UL.
961 2005.05.27 - bug fixes v0.10.17
962 o Un-did essence container and compression descriptor changes.
963 The default build reflects MXF Interop decisions as of 26 May.
964 o Added note about build versions to README (see above).
965 o Added warnings to SMPTE_LABELS builds.
966 o Fixed JP2K essence container label.
969 2005.05.02 - bug fixes v0.10.16
970 o Reorganized internal files, added file reader object, added OS
971 portability header, removed and renamed some files. If you have a
972 patch against previous versions of the source, you should check
974 o Added RGBA attributes to JP2K descriptor.
975 o Changed interface to CodestreamParser.
976 o Added JP2K parser implementation. It is parsing each frame but is
977 not yet being used to populate the descriptor.
978 o Added 48fps option for `asdcp-test -p`.
979 o Added picture rate constants to AS_DCP.h (23.976, 24, 48).
980 o Added sample rate constant to AS_DCP.h (48k).
981 o Changed asdcp-test to encrypt picture headers by default
982 (plaintext offset will be 0), added -E option to allow
986 2005.04.28 - bug fixes v0.9.15
987 o The XML descriptors for the crypto DMS have moved in mxflib to
988 the file DMS_Crypto.xml (they were in DMS_DCPENC.xml). Older
989 installations should update the file from mxflib.
990 o Added Close() and Seek() to ~MyFileWriter(), cleaned up headers
991 o Added UUID generator output mode (-u).
992 o Added -S option to extract PCM essence into stereo wav files
993 o Added more UL testing and conformance checking.
994 o Added macro SMPTE_LABELS which causes the library to be built
995 with SMPTE (as opposed to MXF Interop) labels. This is not
996 set by default, and currently only affects the PCM container
997 label and encrypted element label.
998 o Cleaned up the GNUmakefile test targets, the source files
999 are now named with the TEST_FILE_PREFIX macro.
1000 o enabled 23.976-framed PCM (2002 samples per frame)
1001 o The size of the asdcp-test frame buffer for picture essence
1002 may now be set from the command line (-b). The default is 4MB.
1003 o h__Reader::ReadEKLVPacket() now tests the UL (duh) and switches
1004 on the value, allowing plaintext and ciphertext frames to
1005 be mixed in the file.
1006 o Fixed error in UUID generator format.
1007 o JP2K files now use the GenericPictureDescriptor to store
1008 ContainerDuration and SampleRate. SampleRate is mapped
1009 to EditRate in the PictureDescriptor struct. This fixes
1010 the second caveat from the 0.8.13 release.
1011 o Fxed bug in PCMParserList that was miscalculating the extent
1012 of a PCM sample. This bug did not affect API users, it was
1013 only present in asdcp-test.
1014 o Fixed EditRate on PCM files (was showing sample rate)
1015 o Fixed Encrypted Essence Container UL
1016 o Fixed BlockAlign value for PCM essence
1018 - The following changes were provided by Jeff Loewenguth
1020 o Moved the DMS CryptographicFramework entry from the material
1021 package to the source package
1022 o Fixed erroneous Source Essence Container Label value
1023 o Fixed broken sort of JP2K frames in JP2K parser
1024 o Added FindFrameGOPStart() method to the MPEG2 MXFReader
1025 o Added missing length values for EKLV packets without HMAC
1026 o -x with JP2K essence writes to files with 6 digit names
1028 o The Key ID may now be specified as an argument to asdcp-test
1029 (-j <key-id-string>)
1032 2004.12.30 - bug fixes + wav files v0.8.14
1033 o Added WAV file write to asdcp-test (uses mxflib::waveheader_t).
1034 o Three-partition files reading properly. adscplib still writes
1035 two-partition files.
1036 o Changes in the mxflib WAV essence parser API had broken
1037 asdcplib's ability to read essence from a WAV file. I have
1038 fixed this bug, but at the expense of breaking compatibility
1039 with older versions of mxflib. Beware!
1040 o Removed redundant (but working) bin-text-bin conversions.
1043 2004.12.23 - JPEG 2000 support v0.8.13
1044 o Reads/writes JPEG 2000 essence in plaintext and ciphertext
1045 with the following caveats:
1046 - The Picture Essence Descriptor is empty.
1047 - Because there is no essence descriptor, the reader code
1048 in asdcp-test has no idea how many frames are in the file
1049 and ends with an out-of-bounds frame error. This error
1050 is being suppressed in asdcp-test for the current release.
1051 o Still broken when reading three-partition files.
1054 2004.10.22 - fixes and UL updates v0.7.11
1055 WARNING: COMPATIBILITY BREAKPOINT
1056 Files created with this and future versions of this library are
1057 not compatible with previous versions of this library. As you
1058 might suspect, files created with previous versions of this
1059 library are not compatible with this and future versions.
1061 o h__Reader will now open a three-partitition file (untested)
1062 o Moved DMS from Material partition to File partition
1063 o Added length fields to appropriate places in EKLV packet
1066 2004.10.22 - fixes and UL updates v0.7.10
1067 o fixed frame buffer handling of externally allocated buffer,
1068 created unit test (asdcp-mem-test)
1069 o added operator==() and operator!=() to Rational type
1070 o fixed some type-related compiler warnings
1071 o asdcp-test -p now works on unwrap
1072 o updated some ULs to match documentation (thanks to Arun
1074 o canonicalized line endings
1077 2004.07.02 - full plaintext + ciphertext read/write v0.6.9
1078 o HMAC, plaintext offest and raw ciphertext read supported
1079 o back to proper CBR index
1080 o MPEG temporal offset working
1083 2004.07.01 - plaintext + ciphertext read/write v0.5.8
1084 o encryption of MPEG and PCM essence supported with the
1087 - no plaintext offest support
1088 - no raw ciphertext read support
1089 o moved to reflecting the whole KLV triplet in the CBR
1090 index (now incompatible with mxflib, still searching
1091 for info about what's "right")
1092 o awaitng the following fixes/features:
1093 - retrieve Temporal Offset from index in MPEG2::Reader
1094 - test for correct ULs when reading frame triplets
1095 - fix header metadata items for encrypted files
1097 - plaintext offest support
1098 - raw ciphertext read support
1101 2004.06.14 - plaintext read/write w/key generator v0.4.5
1102 o Project now uses OpenSSL (tested with 0.9.7d on win32, Linux, Darwin)
1103 Use `make ASDCP_WITHOUT_OPENSSL=1` to make plaintext-only version
1104 o Accepts interior I frames when parsing MPEG2 VES
1105 o Improved error reporting on format errors
1106 o Added support for encryption to asdcp-test
1107 o Added RNG for asdcp-test (non-production use only, see notes in FortunaRNG.h)
1108 o Implemented CBC encrypt, decrypt module
1109 o Added partial TemporalOffset retrieval from MPEG2 parser
1110 o Fixed win32 binmode bug
1113 2004.05.12 - plaintext read/write v0.3.4
1114 o Full read/write of plaintext MPEG-2 VES and WAV files
1115 (does not yet support mux from or demux to 2 channel pairs)
1116 o Builds with autoconf-based mxflib
1117 o Added ASDCP_ prefix to macros
1118 o Updated documentation, fixed documentation errors
1119 o Simplified API for MXF writer setup
1120 o Decoupled essence parsers from MXF writers
1121 o added raw ciphertext support to FrameBuffer
1122 o Cleaned up Get/Set naming confusion
1123 o Added missing const qualifiers
1126 2004.04.27 - preview release v0.2.1
1127 o hasty release for quick review
1128 o this release may not build with mxflib using autoconf.
1129 o writes plaintext AS-DCP MPEG2 essence files
1130 o tested under win32 and linux. FreeBSD and Darwin do not work
1133 2004.02.04 - First release (v0.1.1):
1134 o asdcp-test is mostly complete. It should correctly provide
1135 access to the read and info capabilities of the library.
1136 o The MPEG2 reader is functional but not fully tested.
1137 o Some file format integrity tests remain to be coded.
1138 o The PCM reader is mostly complete, I am having difficulty
1139 getting a suitable test file from mxfwrap.
1140 o The makefile creates a static library module. The API
1141 will cleanly support a DSO (or DLL). Let me know if DSO
1142 support is important to you.
1143 o Nothing is thread safe. Thread safety was not a requirement
1144 in the initial project definition. Thread safety may be added
1145 above the mxflib/klvlib level. Let me know if it is important
1147 o The files xmldict.xml and types.xml must be in the current
1148 directory when the program is run. The files are supplied
1149 with mxflib. Runtime location of the files is not currently
1150 a project goal. Comments on how best to handle this situation
1151 would be appreciated. See AS_DCP.cpp at init_mxf_types()
1152 for a more detailed discussion.
