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.

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

213 o Replaced WIN32 directory scanner with dirent_win.h
214 o The NamespaceURI property of AS-02 timed text files has been exposed in the API
215 and via as-02-wrap -P. This behavior replaces previous bad behavior, but puts
216 responsibility for selecting the correct value on the operator.
217 o Exposed CreatePNGNameId and CreateFontNameId subroutines in AS_02::TimedText

243 o Modified the IndexEntry parser to ignore additional bytes belonging to slice
247 2016-05-06 - bug fixes, 2.5.14
249 o Release 2.5.12 caused two problems with Atoms and DTS-X wrapping that are
250 addressed by this release. The UL values that were changed to correct the
251 DCData (ST 429-14) implementation had two unintended side-effects:
252 1. v2.5.12 cannot read old DCData (and thus DTS-X) track files
253 2. v2.5.12 creates broken Atmos track files (incorrect ULs)
254 The fix for this involved the following changes:
255 1. ASDCP::DCData::(MXFReader|MXFWriter) are no longer base classes of
256 ASDCP::ATMOS::(MXFReader|MXFWriter).
257 2. New UL values have been added to carry the original Atoms UL values:
258 a. DolbyAtmosDCDataWrappingFrame
259 b. DolbyAtmosDCDataEssence
260 c. DolbyAtmosDCDataDescriptor
261 3. ASDCP::ATMOS::(MXFReader|MXFWriter) have been modified to use the
262 DolbyAtmosDCData* UL values.
263 4. ASDCP::DCData::MXFReader will parse files having either DCData* or
264 DolbyAtmosDCData* UL values.
265 5. ASDCP::DCData:: MXFWriter continues to use DCData* UL values from ST
267 o Some optional parameters of the MXF metadata packs were being erroneously
268 initialized with a value of zero (0), such as GenericPictureEssenceDescriptor
269 ::SignalStandard, GenericPictureEssenceDescriptor::SampledXOffset(0), etc.
270 o Added higher edit rates (96, 100, 120) to the cinema TimedText_Parser
272 o Defined bool ASDCP::UL::operator<(const UL& rhs) const, which is needed to
273 carry out the version-insensitive lookup policy when searching for ULs in a
274 std::map<> of UL entries.
275 o New files: src/info.in src/CMakeLists.txt
276 o Removed filess: AS_DCP_DCData_internal.h
279 2016-03-17 - bug fixes, 2.5.12
280 o Changed default UNIX file permissions to "666"

289 o Corrected erroneous fixed-tag values in ActiveHeight, ActiveWidth,
290 ActiveXOffset, ActiveYOffset UL definitions.
291 o Provided a stub implementation for Kumu::DirScannerEx (A real
292 implementation will follow soon.)
293 o Added as-02-info program
294 o Added Seek() method to PCM parsers
295 o Added CMakeLists.txt
298 2015-11-10 - bug fixes, IMF text, pink noise, 2.5.11
299 o I moved personal dev environment from older gcc to newer clang. Many
300 small changes were made to satisfy the new compiler:
301 - Altered many printf format codes to use the correct format for the
303 - Parenthesized some expressions to clarify previously ambiguous
304 expectation about precedence.
305 - Created macro KM_MACOSX for use in OS-specific code selection.
306 - Removed last uses of the old C-language abs(), now using Kumu::xabs().
307 - Removed last uses of the old C-language atoi(), not using strtol().
308 o Added platform-independent call Kumu::GetExecutablePath() (to be tested
310 o Added new capabilities to Result_t.
311 o Added imlementation of SMPTE ST 2092-1 pink noise generator.
312 o Added pinkwave CLI utility.
313 o Added font support to the IMF timed-text wrapper.
314 o Fixed a bug that was causing Array properties to be written without
315 the (count, length) header (from PAL).
316 o General review of Batch/Array distinction throughout the project.
317 o Cleaned up definitions of optional properties in all MXF metadata packs.
318 o Fixed Win32 build (from Crowe).
319 o Fixed a bug that caused incorrect failure when parsing JPEG 2000
320 codestreams having fewer than five decomposition levels. (from Korneder).
321 o Fixed missing UUID generation in some instances of the MCALinkID property.
322 o Added -w option to asdcp-wrap to support use of WTF label with MCA.
323 o Altered asdcp-wrap to recognize "-C <UL>" when MCA is being used.
324 o Fixed broken -A <w>/<h> option in as-02-wrap and phdr-wrap.
325 o asdcp-wrap and as-02-wrap now allow split channel groups in MCA labels.
328 2015-02-23 - bug fixes, 2.4.10
329 o Fixed a new bug introduced by the fix to large numbers of subtitle ancillary
331 o Added support for generic Aux Data (ST 429-14) to asdcp-wrap.
334 2015-02-19 - PHDR feature, bug fixes, 2.4.9
335 o Modified PCMParser and PCMParserList to return partial frame buffers at the
336 end of a WAV input file. This was needed to allow wrapping all samples into
337 an AS-02 audio file (which is clip-wrapped) in the case where the input file
338 has an odd number of samples with respect to the frame buffer size being
339 used. If there is more than one input file the length of the last buffer
340 will be determined by PCMParserList to be the shortest of the input files.
341 Prior to this change, partial samples in an input WAV file have been
342 abandoned (i.e., not written out to the MXF file). As a result, AS-DCP
343 applications will have to decide whether to abandon the partial last frame
344 (usually detected by testing frame_buffer.Size() != frame_buffer.Capacity())
345 or write it to the MXF file. Programs written to the old API will write the
346 partial frame (i.e., new behavior.) This should not be harmful since the
347 remainder of the buffer is zeroed and the output file will contain one
348 additional edit unit compared to the previous version.
349 o asdcp-wrap has been modified to test for the partial buffer and by default
350 will complain and abandon the buffer (i.e., same behavior but with a warning
351 message.) A new command line switch (-g) alters this behavior and writes
352 the buffer to the MXF file (it still warns the user that this condition is
354 o as-02-wrap now wraps all samples from the input file to the MXF file. There
355 is no padding, the clip is exactly the set of samples from the input.
356 o as-02 unwrap is temporarily restricted to creating wav files that are
357 aligned with the frame buffer size. This means that the output file will
358 be longer than the original WAV input in the case where the input file has
359 an odd number of samples with respect to the frame buffer size being used.
360 The pad samples are zero (silence).
361 o Modified CalcFramesFromDurationInSamples() to increment the count by one for
362 the case where the input file has an odd number of samples with respect to
363 the frame buffer size being used (previously it truncated the odd samples.)
364 o Fixed ST 429-5 / ST 2067-5 wrapping to increase header space when ancillary
365 resources are present (fixes a bug that cause the header to overflow the
366 allotted space when large numbers of PNG files were present.)
367 o Refactored GetXMLDocType() to use the XML parser.
368 o Added ParseFirstFromString() method to Kumu::XMLElement
369 o Removed Kumu::StringIsXML from the API.
370 o Added ASDCP::MXF::RGBALayout type
371 o Added J2CLayout property to JPEG2000PictureSubDescriptor
372 o Changed km_token_split() to retain empty elements in the output list
373 o Added PHDR wrapping for AS-02.
374 o Added J2CLayout property to the JPEG2000PictureSubDescriptor. This
375 support is preliminary: the Raw data type is being used instead of
376 RGBALayout type, which will be in the next release.
379 2014-10-2 - Bug fixes and enhancements, 2.2.6
380 o Fixed erroneous 377-4 MCA identifier in AS_DCP_PCM dump routine
381 o Fixed erroneous byte 13 in

396 o Added IMF App 2 edit rates in AS_02 namespace: EditRate_29_97,
398 o Revised AEC CBC context objects to copy the key rather than
399 keep the reference passed in to it.
400 o Addressed a bug that would allow unimpeded iteration of component
401 values in a JP2K::PictureDescriptor object.

410 o Fixed broken version numbers on SoundfieldGroupLinkID and
411 GroupOfSoundfieldGroupsLinkID UL values.
412 o Added DBOXMotionCodePrimaryStream and DBOXMotionCodeSecondaryStream UL
413 values to the internal dictionary.
414 o Added optional prefix handling to MCA label generator.
415 o Re-factored MCA label generator to include additional
416 metadata (Thanks to Mike Radford).
417 o Added new options to as-02-wrap.
420 2014-01-06 – Additional IMF/AS-02 support, bug fixes 2.1.1
421 o Fixed missing-index-partion bugs for AS-02 files.
422 o Moved LocalFilenameResolver into the AS_DCP public API so that it
423 can be used by other modules including AS-02.
424 o Did further refactoring of AS-02 Writer classes to separate CBR
425 and VBR indexing implementations.
426 o Fixed wave wrapping UL in clip-wrapped AS-02 files. Renamed some
427 UL constants to reflect "clip" or "frame" wrapping.
428 o Re-factored JP2K_PDesc_to_MD() and MD_to_JP2K_PDesc() to work
429 with GenericPictureEssenceDescriptor objects.

431 CodingStyleDefault and QuantizationDefault when writing the
432 essence descriptor in a JP2K file (AS-DCP and AS-02).
433 o Fixed the version byte on the following UL values:
434 StereoscopicPictureSubDescriptor

440 o Added some essence descriptor options to as-02-wrap.
441 o Changed bit rate display in asdcp-info from mebi-bits/s to
443 o Added "SMPTE" / "Interop" format type display to asdcp-info.
444 o Improved integration of ST 377-4 MCA concepts with ST 429-2 static
446 o Modified asdcp-wrap to assume -L when wrapping timed-text (since
447 there is no MXF text wrapping for Interop.)
448 o Added new EssenceType_t values for IMF/AS-02 track files.
449 o Added detection for AS-02 track files to ASDCP::EssenceType()

457 o Fixed broken sample alignment in RF64Writer (thanks to Wolfgang
459 o Fixed win32 build (thanks to Dolby)
460 o fixed a bug that caused blackwave to only produce 96kHz WAV files.
461 (thanks to Stephane W)
464 2013-07-02 – IMF/AS-02 support, bug fixes 2.0.0
465 o Massive refactoring of internals to allow easier implementation
466 of AS-02. Some API changes were made as well (note that
467 OPAtomHeader is now OP1aHeader and RIP is no longer part of the
468 OP1aHeader.) If you are using this project as a library (and
469 especially if you are keeping patches against it) PLEASE TAKE
470 TIME TO EVALUATE THIS RELEASE THOUROUGHLY BEFORE ADDING IT TO
472 o Final integration of Fraunhoffer IIS code contribution. AS-02
473 files are now fully supported with some TODOs and two major
474 exceptions: LEAD indexes are not supported by the MXF writers
475 and interlace images are not yet supported.
476 o Added support for MCA labels (ST 428-12) to asdcp-wrap. Note
477 that this project is still in the early stages of interop testing
478 so errors are likely present and don't expect any server to
479 make use of this feature.

512 o Added -P option to asdcp-wrap (inserts arbitrary UL into the
513 PictureEssenceCoding property when wrapping JP2K files.)
514 o Added support for 96 kHz files to blackwave.
515 o Added new path and string manglers to Kumu.
516 o Updated MCA ULs (I warned you...). Again please take some
517 time to proof this work against ST 477-4 including the latest
518 drafts of the registries.
519 Changed the version byte (8 0f 16) to 0x0e:
520 MCALabelSubDescriptor
521 AudioChannelLabelSubDescriptor
522 SoundfieldGroupLabelSubDescriptor
523 GroupOfSoundfieldGroupsLabelSubDescriptor
524 GroupOfSoundfieldGroupsLinkID
525 Changed bytes 8 and and 13 of SoundfieldGroupLinkID
526 Added items to the UL dictionary:
537 2012-08-07 - bug fix, 1.10.46
538 o Added missing zero-initializers to time values when parsing a
539 timestamp string (in the case where the optional [Thh:mm.[:ss]]
540 syntax is not present in an encoded string).
542 2012-03-06 - bug fixes, enhancements 1.9.45
543 o Removed ASDCP::Timestamp, all items that were of that class are now
544 of class Kumu::Timestamp
545 o Refactored Kumu::Timestamp to use KM_tai for internal representation
546 (replaced public Y M D, h, m, s variables)
547 o Refactored Kumu::Timestamp to use KM_tai for WIN32 builds
548 o Added UTC offset awareness to Kumu::Timestamp
549 o Replaced "long GetSecondsSinceEpoch(void) const" with
550 "ui64_t GetCTime() const"
551 o Corrected UL version segment in "7.1 DS" and "WTF" audio format
552 labels (corresponds with publication of ST 429-2:2011).
553 o Exposed MXF object interface (MXF.h, Metadata.h) via ASDCP MXFReader
554 and MXFWriter classes.
555 o Added UL values from ST 377-4:2012. >>>>NOTE: These are preliminary
556 values, subject to change upon final publication of not only ST 377-4
557 but also the relevant registries. This is a good time to compare them
558 to the standard and complain if you think they are wrong!
559 o Added MCALabelSubDescriptor, AudioChannelLabelSubDescriptor,
560 SoundfieldGroupLabelSubDescriptor, and
561 GroupOfSoundfieldGroupsLabelSubDescriptor (from ST 377-4:2012) to
563 o Changed some internals to make MXFWriter::OPAtomHeader() work correctly.
564 o Split asdcp-test into several different programs to help relieve
565 the impenetrable-list-of-arguments problem. asdcp-wrap, asdcp-unwrap
566 and asdcp-info take the place of asdcp-test's -c, -x and -i options,
567 respectively. asdcp-util contains the remaining functions. Note that
568 asdcp-test is now DEPRECATED, new functionality and bug fixes will be
569 aimed at the new tools. Also note that some options and calling
570 conventions are different for the new tools as compared to asdcp-test.
571 Please read the synopses and make sure you understand the new idioms.
572 o asdcp-wrap has a new argument, -C <UL>, that writes the given UL to the
573 ChannelAssignment item in the WaveAudioDescriptor (only useful when
574 writing PCM essence).
577 2011-11-30 - bug fixes v1.8.44
578 o Corrected a wrong decryption UL selection when unwrapping MXF.
581 2011-10-27 - bug fixes v1.8.43
582 o Corrected broken Essence UL matching. (Thanks to Michael Loder).
585 2011-08-31 - bug fixes v1.8.42
586 o Added missing HFR support for PCM essence reader/writer.
589 2011-08-30 - bug fixes, enhancements v1.8.41
590 o UL version byte now ignored when comparing UL values.
591 o Changed the version byte in the TimedTextEssence UL to 0x01. There
592 is no published Essence Keys registry so it can't have a maintained
594 o JP2K Sequence Parser modified to skip directory entries that
595 are not files in the case where the parser is initialized with
596 a directory path. When initialized with a list of file names
597 this check is not performed. Based on a hint by Steve Quartly.
598 o Increased the size of the MPEG header parser buffer.
599 o Added missing FrameType() implementation to ASDCP::MPEG2::MXFReader.
600 o Added missing Close() implementations to MXF reader classes.
601 o Added missing Timestamp::Timestamp(const char* datestr) implementation.
602 (Thanks to Matt Sheby for this and the previous three items.)
603 o Fixed error in Kumu::FortunaRNG::FillRandom() that was returning the
604 end of the random buffer instead of the front (Thanks to Mike Radford).
605 o Added support for proposed sound channel format identifiers
606 '7.1DS' and 'WTF'. Optimistically chose version '0x0c'.
607 o Added support for stereoscopic images in JP2K files at edit
608 rates of 48, 50 and 60 eups (96, 100 and 120 fps).
611 2010.11.15 - bug fixes, enhancements v1.7.40
612 o Fixed bug in long KLV packet support (Thanks to Jim Radford).
613 o Fixed AvgBps in PCM files, *again*. Sorry for the crazy.
614 o More fixes and changes in support of 25, 30, 50, 60 fps.
615 (Thanks to Hans K. for the TC rate bug).
616 o Updated KLVFill UL version element to 0x02.
617 o Type change to support Xerces-C 3.x. (Thanks to Matt Sheby).
618 o Some internal API changes to KLV types. Does not affect
620 o Added NetworkLocator type to MXF metadata types.
621 o Added file offset display to klvwalk.
624 2010.09.09 - bug fixes, enhancements, v1.7.39
625 o Fixed bug in JP2K PictureDescriptor initialization in
626 JP2K::MXFReader::OpenRead() and JP2K::MXFSReader::OpenRead()
627 o Once again fiddling with AvgBbs. How can something so simple
628 be such a constant cause of trouble? Tested with 1-, 2- and
629 6-channel input Wav files.
630 o asdcp-test now accepts a directory name when making PCM
631 files (-c). The directory name should be the only filename
632 argument. All files in the directory must be Wav files
633 (mixed channel sizes OK). Files are sorted alphabetically by
634 filename. Hint: use numeric name infix to define order:
643 2010.07.20 - bug fixes, v1.6.37
644 o Fixed TimedTextResourceSubDescriptor UL value.
647 2010.06.16 - bug fixes, v1.6.36
648 o Added support for new Edit Rates to asdcp-test.cpp.
649 o Expanded timed-text file reader in asdcp-test.cpp.
650 o Fixed large BER value encoding (plaintext) and decoding
651 (plaintext and ciphertext). This feature was introduced in
653 o Fixed AvgBps value for multi-channel Wave input.
656 2010.05.13 - bug fixes, enhancements, v1.6.34
657 o ST 429-5 files have corrected ULs for DCTimedTextDescriptor and
658 GenericStream DataElement. Files made with previous versions of
659 the library are incompatible with this and future versions.
660 o Fixed File Package TrackNumber values. Th
662 o Added edit rate constants to AS_DCP.h (25, 30, 50, 60).
663 o Changed AudioDescriptor "SampleRate" element name to "EditRate"
664 to make it consistent with the other types.
665 o Now builds with XercesC 3.x.
666 o KM_memio.h has better const behavior.
667 o Fixed a bug in KM_memio.h string archiving.
670 2010.01.05 - bug fixes, enhancements, v1.5.32
671 o Re-fixed swapped Interop and SMPTE OP Atom UL values. The swap
672 introduced in v1.5.31 was done in error.
673 o Added -z,-Z options to asdcp-test (j2c parameter checking)
674 o Reformed jp2k-test as j2c-test, added help and list processing,
675 added to standard install target.
678 2009.12.31 - bug fixes, enhancements, v1.5.31
679 o Fixed swapped Interop and SMPTE OP Atom UL values.
680 o Added get_BER_length_for_value() subroutine.
681 o Modified ASDCP::h__Writer::WriteEKLVPacket() to allow larger BER
682 lengths for KLV packets larger than 16 MB. This was required to
683 support large font files in the SMPTE 429-5 implementation.
686 2009.11.06 - bug fixes, enhancements, v1.5.29
687 o Fixed a bug that could cause HMAC values to be incorrectly
688 stored in MXF files. Files created with versions of asdcplib
689 prior to this version may have incorrect HMAC values.
690 o Improved handing of XML files for MXF wrapping.
691 o Jpeg2000 codestream EditRate and SampleRate mismatches
692 now warns instead of returning an error.
693 o Improved error handling in Jpeg2000 sequence parsing routines.
694 o Added two methods to Kumu::Timestamp, AddSeconds(), to add (or
695 subtract) seconds to a time value, and GetSecondsSinceEpoch()
696 to get the number of seconds since the unix epoch.
697 o Added new option to asdcp-test, '-a', to specify a UUID when
699 o Added support for specifying the intrinsic duration of MXF files
700 containing timed text.
701 o Added new option to wavesplit, '-i', to display WAV file metadata.
704 2009.05.21 - bug fixes, v.1.4.24
705 o Fixed a bug that caused incorrect SubDescriptors UL values to be
706 written into interop format MXF track files. Note that this involved
707 a substantial reorganization of MXF internals. Please test thoroughly
708 in your application before using in production. Note that this is a
709 significant bug fix and track files created with 1.4.22 may be incompatible
713 2009.04.09 - SMPTE format fixes, enhancements and bug fixes, v.1.4.22
714 o asdcplib now uses GNU autotools on POSIX systems to configure
715 and build. See "./configure" for details. Note that two options,
716 --enable-freedist and --with-python are not enabled in the free
717 version of asdcplib and should not be used.
718 o Added build option (CONFIG_RANDOM_UUID) to enable mixed case UUID
719 generation when environment variable KM_USE_RANDOM_UUID is defined.
720 o Fixed a condition that could cause an error to occur when wrapping
721 SMPTE format timed text track files that do not define a starting
723 o Updated ULs for SMPTE format track files.
724 o SampleRate added to JP2K metadata
725 o Support for wrapping 96kHz WAV files added.
726 o Updated ULs for audio channel formats (ChannelFormat)
727 o Updated font subdescriptor MIME Types for TimedText Trackfiles.
728 o Changed time implementation to support dates beyond Jan 19th, 2038.
729 o Xerces-C XML parser support added.
730 o New build method for Windows (see win32/README.txt for details).
731 o Added new functionality in Kumu to recursively create and delete files
732 and directories, and get free disk space for a given volume path.
733 o Added a method to Kumu::Timestamp, AddMinutes(), to add (or subtract)
734 minutes to a time value.
735 o Improved how Kumu::Timestamp parses timestamps with offsets.
736 o Fixed a bug that caused incorrect HMAC values to be calculated.
739 2008.02.16 - SMPTE format fixes, bug fixes v.1.3.18
740 o Added correct SMPTE UL for StereoscopicPictureSubDescriptor.
741 o Exposed JP2K metadata parser as ParseMetadataIntoDesc().
742 o Added simple stereoscopic framebuffer to support paired ReadFrame()
743 and WriteFrame() methods (allows simpler integration with other
745 o Improved detection of JPEG Interop stereoscopic files.
746 o Win32 build fixes (Thanks to Mike Crowe at DTS).
747 o Added the WITH_MD macro to the makefile. Set this value to one
748 to build Win32 with /MD[d] instead of /MT[d].
749 o The Generic Container UL has been added to the EssenceContainers
750 set in the header partition pack for encrypted files. It has always
751 been there in plaintext files.
752 - Below this point the changes are internal and should not affect you
753 unless you use Kumu directly.
754 o Major refactoring of KM_log.[h|cpp].
755 o Fixed buffer re-sizing issue in Kumu::ByteString.
756 o Replaced type IdentifierList with ArchivableList.
757 o Added COPYING file to the release bundle.
760 2007.12.13 - Bug fixes v.1.2.17
761 o Changed Result_t implementation to use int instead of long, which
762 was causing trouble on some 64 bit platforms.
763 o Fixed EKLV HMAC. NOTE: Breaks backward compatibility with older
764 Interop files. To validate these files, use asdcplib-1.1.14. This
765 should not cause too much trouble since files with broken and
766 non-broken HMAC have been in the wild for years without issue.
767 o Fixed HMAC sequence numbering in encrypted stereoscopic files.
768 o Finished stereoscopic test targets in the makefile.
769 o Fixed the win32 build, now expects VS2005 compiler by default,
770 use WITH_VC6=1 top get VC6 flags.
771 o Stereoscopic and Timed Text modes now have SMPTE UL values.
772 NOTE: SMPTE 429-5 and 429-10 are not yet published. It is possible
773 that these UL values may change before publication. Please use
774 caution when using these features for production work.
775 o Changed a bunch of symbol names in the 429-5 implementation to
776 better match the spec.
777 o Added -U option to asdcp-test to dump the UL library to stdout.
778 o Fixed erroneous placement of the PictureEssenceCoding UL in JP2K
779 files (Interop and SMPTE modes).
782 2007.10.22 - Timed Text, Stereoscopic Picture and Bug fixes v.1.2.16
783 o Significant API changes have been made. Please read all entries
784 in this changelog to be sure you understand the changes. Also
785 note that some changes have been made to LS_MXF_SMPTE files that
786 are incompatible with earlier releases (e.g., EKLV HMAC). If
787 you are looking for a stable interop release, use v.1.1.14.
788 o Fixed RFC 2104 HMAC implementation for LS_MXF_SMPTE only. The
789 broken implementation has been maintained for Interop mode.
790 o Added support for draft SMPTE 429-5 Timed Text Track File. This
791 is still waiting for official SMPTE ULs, so do not use it for
792 shipping products. An XML parser is needed to create a Timed
793 Text Track File; Expat is now an optional part of the build.
794 Make with WITH_XML_PARSER=1 to link with Expat. If you do not
795 link with expat, you will get an error when using the TimedText::
796 DCSubtitleParser class. See also S429-5-cgi.cpp for an example
797 that shows how to serve plaintext MXF file elements directly via
799 o Added support for draft SMPTE 429-10 Stereoscopic Picture Track
800 File, including the JPEG Interop version. This is still waiting
801 for official SMPTE ULs, so do not use it with LS_MXF_SMPTE for
803 o Refactored the following files as a side-effect of the above
804 work: AS_DCP_JP2K.cpp AS_DCP_MPEG2.cpp AS_DCP_PCM.cpp
805 AS_DCP_MXF.cpp AS_DCP_internal.h MXF.[h|cpp] MXFTypes.[h|cpp]
806 Metadata.[h|cpp] h__Reader.cpp h__Writer.cpp klvwalk.cpp.
807 WARNING: While significant effort has been extended to make sure
808 that these changes do not affect existing stable file support,
809 users are cautioned to test this release thouroughly.
810 o Added a large set of filesystem path manglers to KM_fileio.h. See
811 path-test.cpp for example usage. The path manglers have not yet
812 been tested on win32 platforms (they are currently used only by
813 the Timed Text module.
814 o The PathIsFile(), PathIsDirectory() and FileSize() subroutines
815 have been modified to accept const std::string& instead of
817 o Added namespace and parsing support (Expat) to Kumu::XMLElement
818 (currently used only for Timed Text support). Also added some
820 o Altered MXF::UTF16String to use mbtowc() and wctomb().
823 2007.03.31 - Bug fixes v.1.1.14
824 o Fixed KeyFrameOffset value in MPEG wrapping to have negative
825 value. This is probably not yet complete for handling all
826 types of GOPs. Please send chunks of MPEG-2 VES that you
827 find which break this. Thanks to Doremi.
828 ** no other file format changes in this release **
829 o Fixed error in RIP interpretation when reading arbitrary (i.e.,
831 o Fixed a memory leak in ASDCP::MXF::OPAtomHeader when used
832 in read mode. Thanks to Mahesh Bajaj for pointing out this
833 bug and the one above.
834 o Removed asserts from KM_fileio, replaced with RESULT_WRITEFAIL
835 return value statements.
836 o Added -s and -p to the makefile install target.
837 o Altered ByteString behavior to use target Length() in copy
838 operations (instead of Capacity()).
839 o Added new Set() method to ByteString.
840 o Fixed a bug in ByteString::Unarchive() that caused the operation
841 to fail when the buffer was smaller than the read (i.e., when
842 Capacity() was called).
843 o Added IdentifierList class to KM_util.h.
844 o Changed some Error() messages to Debug() in Wav.cpp
845 o Revived jp2k-test.cpp and asdcp-mem-test.cpp (they both had
849 2007.02.15 - Bug fixes v1.1.13
850 o Removed 'VDescObj->SampleRate.Numerator = VDesc.FrameRate;'
851 from MPEG2_VDesc_to_MD() in AS_DCP_MPEG2.cpp, was line 76.
852 o Added KM_TEST_NULL_STR_L() and KM_TEST_NULL_L() macros to
853 KM_log.h. These versions log the location of the null value.
854 Macros are now used in any module that includes KM_log.h.
855 o MPEG2 VES with run of zero values at the head is now OK.
856 o Increased VESHeaderBufSize to 16K.
857 o Added makefile support for local OpenSSL in ../openssl, if
859 o The Kumu::PathIs*() functions now return false if a null or
860 empty string is given (used to be an assert).
861 o Cleaned up the install target in the makefile.
862 o Fixed SMPTE 429-6 HMAC -- FIPS 186-2 implementation was
863 laughably incorrect. Thanks to Doremi for pointing this out.
864 o Removed default parameter to HMACContext::InitKey().
865 o Cleaned up messages and CLI arg handling in asdcp-test.
868 2006.11.19 - Mo better stuff v1.1.12
869 o Changed read-only Result_t accessor methods to const.
870 o Added Base64 (-B) option to kmrandgen.
871 o Removed 16-bit alignment restriction from kmrandgen.
872 o Improved WAV file extraction speed (Thanks to Jim Radford
873 for pointing this out).
874 o Added single-channel split for WAV extraction (asdcp-test -1).
875 o Fixed remainder bug in h__RNG::fill_rand().
878 2006.11.03 - Bug fixes v1.1.11
879 o Increased index table entry list size to 5000.
880 o Added length checking to TLV writer (returns error if TLV
881 payload exceeds 64kB).
882 o Fixed partition header and RIP errors related to 2-partition
883 files (MXF Interop mode).
884 o Added -t option to asdcp-test (SHA-1 digest with Base64 output
886 o Fixed Sub Descriptor reference bug (Thanks to Denis Leconte
887 for dogged determination).
888 o Added directory-of-wav detection to RawEssenceType()
889 o Modified MXF::Partition::AddChildObject() to only generate
890 a UUID if the InstanceID is unset.
891 o Added ComponentMaxRef & ComponentMinRef to RGBAEssenceDescriptor.
893 o Added detection of 2K/4K jp2c, writing correct 4K metadata.
896 2006.10.05 - Bug fixes v1.1.10
897 o Changed RM_RELEASE to RL_RELEASE in MXFTypes.h.
898 o Changed the MXF writer to use RL_RELEASE (was RL_DEVELOPMENT).
899 o Really fixed source reference chain.
900 o Updated JP2K file package label.
901 o Changed location of JPEG2000PictureSubDescriptor in the
902 header (was erroneously before Preface).
903 o Altered LS_MXF_INTEROP to produce 2-partition files.
906 2006.09.25 - Bug fixes v1.1.9
907 o Fixed SourcePackageID value. All files will be 'original',
908 i.e. SourcePackageID will be all zeros. Let me know if you
909 want to set SourcePackageID.
910 o Fixed compiler warnings on some Linux platforms
911 o Fixed the build so that BUILD_DIR is no longer created
913 o Added duration detection to the raw essence parsers. The
914 MPEG parser uses a nasty approximation so don't use it
915 without paying close attention to the result.
916 o Modified PCMParserList to make it more useful as a base
918 o Fixed bugs and re-organized command-line help in asdcp-test
920 o Fixed two-partition file reads.
921 o Fixed Win32 PRNG initialization.
922 o Renamed asdcp-lf-test as kmfilegen.
923 o Added kmrandgen and kmuuidgen.
924 o Added string retrieval mechanism to Result_t.
925 o Refactored Kumu::Identifier and its sub-classes.
926 o Altered Kumu::PathIsFile to return true when the path
927 is a symbolic link (unix only).
928 o Altered Kumu::FileWriter::OpenWrite to use file creation
929 mode 0664 (was 0644) (unix only).
930 o Added Kumu::WriteStringIntoFile() subroutine.
933 2006.04.05 - Bug fixes and new stuff v1.1.7
934 o Fixed a bug in the MPEG parser that caused it to fail when
935 handling start codes spanning buffer boundaries
936 o Added wavesplit and blackwave utility programs
937 o Added support for revised SMPTE HMAC key derivation when
939 o Refactored platform compatibility and general utilities
940 into a new sub-library "Kumu". There are no new build
941 steps or dependencies, but some important things have
943 + Result_t is no longer an enum, it is now a class.
944 Library result codes are now declared as const objects
947 const Kumu::Result_t RESULT_FORMAT (-101, "The file...");
949 The macros ASDCP_SUCCESS and ASDCP_FAILURE still work
950 the same way thanks to an operator overload for type long.
951 See KM_error.h for more information.
952 + The logging interface has been moved out of AS_DCP.h
954 o Some of the command line utilities that were using headers
955 other than AS_DCP.h have been changed to use the Kumu
956 equivalents. If you have code based on those utilities, you
957 will have to update by hand.
958 o Added new types to the EssenceType_t enum.
959 o The guard macro for Win32 code has changed from WIN32 to
963 2006.03.2x - new stuff
964 o Proper handling of stream-id byte of essence UL values
965 o writes 3-partition files, reads 2-part or 3-part
968 2006.03.16 - bug fixes plus
969 o Removed SMPTE_LABELS compile-time option. The reader will now
970 silently accept either SMPTE or MXF Interop labels, the writer
971 can be instructed which to use at runtime. Default is Interop.
972 o Added an AIFF reader. Support is preliminary, it works with the
973 AIFF files I have on hand.
974 o More code refactoring. More to come.
977 2006.03.09 - full read-write
978 o Removed ASDCP_WITHOUT_OPENSSL compile-time option.
979 o Full read/write now working on new MXF library
982 2005.00.00 - A New Hope
983 o The temporary mxf-lite has been removed. MXF files are now
984 managed via the objects in KLV.h, MXFTypes.h MXF.h and
985 Metadata.h. This release does not support writing MXF files.
986 o Fixed a header interpretation error in the Wav parser.
989 2005.00.00 - The Reformation
990 o Removed mxflib as a dependency by forking the necessary
991 functions and placing them in the mxf-lite subdirectory.
992 Please note that the very heavy modifications done here
993 render all comparisson to mxflib code a substantial task.
994 All errors are now mine and users are warned not to bug
995 Oliver or Matt for help with this code. The version of
996 mxflib at the time of the fork was: 0.5.1.3.
999 2005.06.03 - bug fixes v0.10.18
1000 o Updated UL batch to include GC UL.
1003 2005.05.27 - bug fixes v0.10.17
1004 o Un-did essence container and compression descriptor changes.
1005 The default build reflects MXF Interop decisions as of 26 May.
1006 o Added note about build versions to README (see above).
1007 o Added warnings to SMPTE_LABELS builds.
1008 o Fixed JP2K essence container label.
1011 2005.05.02 - bug fixes v0.10.16
1012 o Reorganized internal files, added file reader object, added OS
1013 portability header, removed and renamed some files. If you have a
1014 patch against previous versions of the source, you should check
1016 o Added RGBA attributes to JP2K descriptor.
1017 o Changed interface to CodestreamParser.
1018 o Added JP2K parser implementation. It is parsing each frame but is
1019 not yet being used to populate the descriptor.
1020 o Added 48fps option for `asdcp-test -p`.
1021 o Added picture rate constants to AS_DCP.h (23.976, 24, 48).
1022 o Added sample rate constant to AS_DCP.h (48k).
1023 o Changed asdcp-test to encrypt picture headers by default
1024 (plaintext offset will be 0), added -E option to allow
1028 2005.04.28 - bug fixes v0.9.15
1029 o The XML descriptors for the crypto DMS have moved in mxflib to
1030 the file DMS_Crypto.xml (they were in DMS_DCPENC.xml). Older
1031 installations should update the file from mxflib.
1032 o Added Close() and Seek() to ~MyFileWriter(), cleaned up headers
1033 o Added UUID generator output mode (-u).
1034 o Added -S option to extract PCM essence into stereo wav files
1035 o Added more UL testing and conformance checking.
1036 o Added macro SMPTE_LABELS which causes the library to be built
1037 with SMPTE (as opposed to MXF Interop) labels. This is not
1038 set by default, and currently only affects the PCM container
1039 label and encrypted element label.
1040 o Cleaned up the GNUmakefile test targets, the source files
1041 are now named with the TEST_FILE_PREFIX macro.
1042 o enabled 23.976-framed PCM (2002 samples per frame)
1043 o The size of the asdcp-test frame buffer for picture essence
1044 may now be set from the command line (-b). The default is 4MB.
1045 o h__Reader::ReadEKLVPacket() now tests the UL (duh) and switches
1046 on the value, allowing plaintext and ciphertext frames to
1047 be mixed in the file.
1048 o Fixed error in UUID generator format.
1049 o JP2K files now use the GenericPictureDescriptor to store
1050 ContainerDuration and SampleRate. SampleRate is mapped
1051 to EditRate in the PictureDescriptor struct. This fixes
1052 the second caveat from the 0.8.13 release.
1053 o Fxed bug in PCMParserList that was miscalculating the extent
1054 of a PCM sample. This bug did not affect API users, it was
1055 only present in asdcp-test.
1056 o Fixed EditRate on PCM files (was showing sample rate)
1057 o Fixed Encrypted Essence Container UL
1058 o Fixed BlockAlign value for PCM essence
1060 - The following changes were provided by Jeff Loewenguth
1062 o Moved the DMS CryptographicFramework entry from the material
1063 package to the source package
1064 o Fixed erroneous Source Essence Container Label value
1065 o Fixed broken sort of JP2K frames in JP2K parser
1066 o Added FindFrameGOPStart() method to the MPEG2 MXFReader
1067 o Added missing length values for EKLV packets without HMAC
1068 o -x with JP2K essence writes to files with 6 digit names
1070 o The Key ID may now be specified as an argument to asdcp-test
1071 (-j <key-id-string>)
1074 2004.12.30 - bug fixes + wav files v0.8.14
1075 o Added WAV file write to asdcp-test (uses mxflib::waveheader_t).
1076 o Three-partition files reading properly. adscplib still writes
1077 two-partition files.
1078 o Changes in the mxflib WAV essence parser API had broken
1079 asdcplib's ability to read essence from a WAV file. I have
1080 fixed this bug, but at the expense of breaking compatibility
1081 with older versions of mxflib. Beware!
1082 o Removed redundant (but working) bin-text-bin conversions.
1085 2004.12.23 - JPEG 2000 support v0.8.13
1086 o Reads/writes JPEG 2000 essence in plaintext and ciphertext
1087 with the following caveats:
1088 - The Picture Essence Descriptor is empty.
1089 - Because there is no essence descriptor, the reader code
1090 in asdcp-test has no idea how many frames are in the file
1091 and ends with an out-of-bounds frame error. This error
1092 is being suppressed in asdcp-test for the current release.
1093 o Still broken when reading three-partition files.
1096 2004.10.22 - fixes and UL updates v0.7.11
1097 WARNING: COMPATIBILITY BREAKPOINT
1098 Files created with this and future versions of this library are
1099 not compatible with previous versions of this library. As you
1100 might suspect, files created with previous versions of this
1101 library are not compatible with this and future versions.
1103 o h__Reader will now open a three-partitition file (untested)
1104 o Moved DMS from Material partition to File partition
1105 o Added length fields to appropriate places in EKLV packet
1108 2004.10.22 - fixes and UL updates v0.7.10
1109 o fixed frame buffer handling of externally allocated buffer,
1110 created unit test (asdcp-mem-test)
1111 o added operator==() and operator!=() to Rational type
1112 o fixed some type-related compiler warnings
1113 o asdcp-test -p now works on unwrap
1114 o updated some ULs to match documentation (thanks to Arun

1126 o encryption of MPEG and PCM essence supported with the
1129 - no plaintext offest support
1130 - no raw ciphertext read support
1131 o moved to reflecting the whole KLV triplet in the CBR
1132 index (now incompatible with mxflib, still searching
1133 for info about what's "right")
1134 o awaitng the following fixes/features:
1135 - retrieve Temporal Offset from index in MPEG2::Reader
1136 - test for correct ULs when reading frame triplets
1137 - fix header metadata items for encrypted files
1139 - plaintext offest support
1140 - raw ciphertext read support
1143 2004.06.14 - plaintext read/write w/key generator v0.4.5
1144 o Project now uses OpenSSL (tested with 0.9.7d on win32, Linux, Darwin)
1145 Use `make ASDCP_WITHOUT_OPENSSL=1` to make plaintext-only version
1146 o Accepts interior I frames when parsing MPEG2 VES
1147 o Improved error reporting on format errors
1148 o Added support for encryption to asdcp-test
1149 o Added RNG for asdcp-test (non-production use only, see notes in FortunaRNG.h)
1150 o Implemented CBC encrypt, decrypt module
1151 o Added partial TemporalOffset retrieval from MPEG2 parser
1152 o Fixed win32 binmode bug
1155 2004.05.12 - plaintext read/write v0.3.4
1156 o Full read/write of plaintext MPEG-2 VES and WAV files
1157 (does not yet support mux from or demux to 2 channel pairs)

1168 2004.04.27 - preview release v0.2.1
1169 o hasty release for quick review
1170 o this release may not build with mxflib using autoconf.
1171 o writes plaintext AS-DCP MPEG2 essence files
1172 o tested under win32 and linux. FreeBSD and Darwin do not work
1175 2004.02.04 - First release (v0.1.1):
1176 o asdcp-test is mostly complete. It should correctly provide
1177 access to the read and info capabilities of the library.
1178 o The MPEG2 reader is functional but not fully tested.
1179 o Some file format integrity tests remain to be coded.
1180 o The PCM reader is mostly complete, I am having difficulty
1181 getting a suitable test file from mxfwrap.
1182 o The makefile creates a static library module. The API
1183 will cleanly support a DSO (or DLL). Let me know if DSO
1184 support is important to you.
1185 o Nothing is thread safe. Thread safety was not a requirement
1186 in the initial project definition. Thread safety may be added
1187 above the mxflib/klvlib level. Let me know if it is important
1189 o The files xmldict.xml and types.xml must be in the current
1190 directory when the program is run. The files are supplied
1191 with mxflib. Runtime location of the files is not currently
1192 a project goal. Comments on how best to handle this situation
1193 would be appreciated. See AS_DCP.cpp at init_mxf_types()
1194 for a more detailed discussion.
