35 o Added "FSKSync" audio channel label to the MCA label generator
36 o SMPTE RDD 45 requires a minimum BER encoding length of five (5) bytes for
37 Content Element packets. The Write_EKLV_Packet() API has been modified to
38 allow the specification of this value. All existing wrapping modules have
39 been changed to conform to the new API, and all continue to use four (4)
40 as the minimum BER encoding length. Write_EKLV_Packet() will continue to
41 generate BER encodings with a length greater than the specified minimum for
42 payloads that are larger than values encoded using the specified minimum.
46 o Fixes wrong MajorVersion in Preface
47 o Adds VideoLineMap also to RGBA essence descriptor

156 o Modified the IndexEntry parser to ignore additional bytes belonging to slice
160 2016-05-06 - bug fixes, 2.5.14
162 o Release 2.5.12 caused two problems with Atoms and DTS-X wrapping that are
163 addressed by this release. The UL values that were changed to correct the
164 DCData (ST 429-14) implementation had two unintended side-effects:
165 1. v2.5.12 cannot read old DCData (and thus DTS-X) track files
166 2. v2.5.12 creates broken Atmos track files (incorrect ULs)
167 The fix for this involved the following changes:
168 1. ASDCP::DCData::(MXFReader|MXFWriter) are no longer base classes of
169 ASDCP::ATMOS::(MXFReader|MXFWriter).
170 2. New UL values have been added to carry the original Atoms UL values:
171 a. DolbyAtmosDCDataWrappingFrame
172 b. DolbyAtmosDCDataEssence
173 c. DolbyAtmosDCDataDescriptor
174 3. ASDCP::ATMOS::(MXFReader|MXFWriter) have been modified to use the
175 DolbyAtmosDCData* UL values.
176 4. ASDCP::DCData::MXFReader will parse files having either DCData* or
177 DolbyAtmosDCData* UL values.
178 5. ASDCP::DCData:: MXFWriter continues to use DCData* UL values from ST
180 o Some optional parameters of the MXF metadata packs were being erroneously
181 initialized with a value of zero (0), such as GenericPictureEssenceDescriptor
182 ::SignalStandard, GenericPictureEssenceDescriptor::SampledXOffset(0), etc.
183 o Added higher edit rates (96, 100, 120) to the cinema TimedText_Parser
185 o Defined bool ASDCP::UL::operator<(const UL& rhs) const, which is needed to
186 carry out the version-insensitive lookup policy when searching for ULs in a
187 std::map<> of UL entries.
188 o New files: src/info.in src/CMakeLists.txt
189 o Removed filess: AS_DCP_DCData_internal.h
192 2016-03-17 - bug fixes, 2.5.12

202 o Corrected erroneous fixed-tag values in ActiveHeight, ActiveWidth,
203 ActiveXOffset, ActiveYOffset UL definitions.
204 o Provided a stub implementation for Kumu::DirScannerEx (A real
205 implementation will follow soon.)
206 o Added as-02-info program
207 o Added Seek() method to PCM parsers
208 o Added CMakeLists.txt
211 2015-11-10 - bug fixes, IMF text, pink noise, 2.5.11
212 o I moved personal dev environment from older gcc to newer clang. Many
213 small changes were made to satisfy the new compiler:
214 - Altered many printf format codes to use the correct format for the
216 - Parenthesized some expressions to clarify previously ambiguous
217 expectation about precedence.
218 - Created macro KM_MACOSX for use in OS-specific code selection.
219 - Removed last uses of the old C-language abs(), now using Kumu::xabs().
220 - Removed last uses of the old C-language atoi(), not using strtol().
221 o Added platform-independent call Kumu::GetExecutablePath() (to be tested
223 o Added new capabilities to Result_t.
224 o Added imlementation of SMPTE ST 2092-1 pink noise generator.
225 o Added pinkwave CLI utility.
226 o Added font support to the IMF timed-text wrapper.
227 o Fixed a bug that was causing Array properties to be written without
228 the (count, length) header (from PAL).
229 o General review of Batch/Array distinction throughout the project.
230 o Cleaned up definitions of optional properties in all MXF metadata packs.
231 o Fixed Win32 build (from Crowe).
232 o Fixed a bug that caused incorrect failure when parsing JPEG 2000
233 codestreams having fewer than five decomposition levels. (from Korneder).
234 o Fixed missing UUID generation in some instances of the MCALinkID property.
235 o Added -w option to asdcp-wrap to support use of WTF label with MCA.
236 o Altered asdcp-wrap to recognize "-C <UL>" when MCA is being used.
237 o Fixed broken -A <w>/<h> option in as-02-wrap and phdr-wrap.
238 o asdcp-wrap and as-02-wrap now allow split channel groups in MCA labels.
241 2015-02-23 - bug fixes, 2.4.10
242 o Fixed a new bug introduced by the fix to large numbers of subtitle ancillary
244 o Added support for generic Aux Data (ST 429-14) to asdcp-wrap.
247 2015-02-19 - PHDR feature, bug fixes, 2.4.9
248 o Modified PCMParser and PCMParserList to return partial frame buffers at the
249 end of a WAV input file. This was needed to allow wrapping all samples into
250 an AS-02 audio file (which is clip-wrapped) in the case where the input file
251 has an odd number of samples with respect to the frame buffer size being
252 used. If there is more than one input file the length of the last buffer
253 will be determined by PCMParserList to be the shortest of the input files.
254 Prior to this change, partial samples in an input WAV file have been
255 abandoned (i.e., not written out to the MXF file). As a result, AS-DCP
256 applications will have to decide whether to abandon the partial last frame
257 (usually detected by testing frame_buffer.Size() != frame_buffer.Capacity())
258 or write it to the MXF file. Programs written to the old API will write the
259 partial frame (i.e., new behavior.) This should not be harmful since the
260 remainder of the buffer is zeroed and the output file will contain one
261 additional edit unit compared to the previous version.
262 o asdcp-wrap has been modified to test for the partial buffer and by default
263 will complain and abandon the buffer (i.e., same behavior but with a warning
264 message.) A new command line switch (-g) alters this behavior and writes
265 the buffer to the MXF file (it still warns the user that this condition is
267 o as-02-wrap now wraps all samples from the input file to the MXF file. There
268 is no padding, the clip is exactly the set of samples from the input.
269 o as-02 unwrap is temporarily restricted to creating wav files that are
270 aligned with the frame buffer size. This means that the output file will
271 be longer than the original WAV input in the case where the input file has
272 an odd number of samples with respect to the frame buffer size being used.
273 The pad samples are zero (silence).
274 o Modified CalcFramesFromDurationInSamples() to increment the count by one for
275 the case where the input file has an odd number of samples with respect to
276 the frame buffer size being used (previously it truncated the odd samples.)
277 o Fixed ST 429-5 / ST 2067-5 wrapping to increase header space when ancillary
278 resources are present (fixes a bug that cause the header to overflow the
279 allotted space when large numbers of PNG files were present.)
280 o Refactored GetXMLDocType() to use the XML parser.
281 o Added ParseFirstFromString() method to Kumu::XMLElement
282 o Removed Kumu::StringIsXML from the API.
283 o Added ASDCP::MXF::RGBALayout type
284 o Added J2CLayout property to JPEG2000PictureSubDescriptor
285 o Changed km_token_split() to retain empty elements in the output list
286 o Added PHDR wrapping for AS-02.
287 o Added J2CLayout property to the JPEG2000PictureSubDescriptor. This
288 support is preliminary: the Raw data type is being used instead of
289 RGBALayout type, which will be in the next release.
292 2014-10-2 - Bug fixes and enhancements, 2.2.6
293 o Fixed erroneous 377-4 MCA identifier in AS_DCP_PCM dump routine

309 o Added IMF App 2 edit rates in AS_02 namespace: EditRate_29_97,
311 o Revised AEC CBC context objects to copy the key rather than
312 keep the reference passed in to it.
313 o Addressed a bug that would allow unimpeded iteration of component
314 values in a JP2K::PictureDescriptor object.
315 o Addressed a bug that was incorrectly recording the sequence Duration
316 in MXF Track objects.
317 o Added ASDCP::AtmosSyncChannelMixer::AppendSilenceChannels()
318 o Added a QCD decoder to the j2c parser.
319 o Altered ASDCP::KLVPacket::HasUL() to use version-blind matching.
320 o Fixed an uninitialized variable in MemIOReader::ReadString() that
321 caused unbounded reads.
322 o Fixed broken ByteString::ArchiveLength() method
323 o Fixed broken version numbers on SoundfieldGroupLinkID and
324 GroupOfSoundfieldGroupsLinkID UL values.
325 o Added DBOXMotionCodePrimaryStream and DBOXMotionCodeSecondaryStream UL
326 values to the internal dictionary.
327 o Added optional prefix handling to MCA label generator.
328 o Re-factored MCA label generator to include additional
329 metadata (Thanks to Mike Radford).
330 o Added new options to as-02-wrap.

334 o Fixed missing-index-partion bugs for AS-02 files.
335 o Moved LocalFilenameResolver into the AS_DCP public API so that it
336 can be used by other modules including AS-02.
337 o Did further refactoring of AS-02 Writer classes to separate CBR
338 and VBR indexing implementations.
339 o Fixed wave wrapping UL in clip-wrapped AS-02 files. Renamed some
340 UL constants to reflect "clip" or "frame" wrapping.
341 o Re-factored JP2K_PDesc_to_MD() and MD_to_JP2K_PDesc() to work
342 with GenericPictureEssenceDescriptor objects.
343 o Fixed a bug that was suppressing PictureComponentSizing,
344 CodingStyleDefault and QuantizationDefault when writing the
345 essence descriptor in a JP2K file (AS-DCP and AS-02).
346 o Fixed the version byte on the following UL values:
347 StereoscopicPictureSubDescriptor
348 GenericPictureEssenceDescriptor_ColorPrimaries
349 GenericPictureEssenceDescriptor_ActiveHeight
350 GenericPictureEssenceDescriptor_ActiveWidth
351 GenericPictureEssenceDescriptor_ActiveXOffset
352 GenericPictureEssenceDescriptor_ActiveYOffset
353 o Added some essence descriptor options to as-02-wrap.
354 o Changed bit rate display in asdcp-info from mebi-bits/s to
356 o Added "SMPTE" / "Interop" format type display to asdcp-info.
357 o Improved integration of ST 377-4 MCA concepts with ST 429-2 static
359 o Modified asdcp-wrap to assume -L when wrapping timed-text (since
360 there is no MXF text wrapping for Interop.)
361 o Added new EssenceType_t values for IMF/AS-02 track files.
362 o Added detection for AS-02 track files to ASDCP::EssenceType()

374 (thanks to Stephane W)
377 2013-07-02 – IMF/AS-02 support, bug fixes 2.0.0
378 o Massive refactoring of internals to allow easier implementation
379 of AS-02. Some API changes were made as well (note that
380 OPAtomHeader is now OP1aHeader and RIP is no longer part of the
381 OP1aHeader.) If you are using this project as a library (and
382 especially if you are keeping patches against it) PLEASE TAKE
383 TIME TO EVALUATE THIS RELEASE THOUROUGHLY BEFORE ADDING IT TO
385 o Final integration of Fraunhoffer IIS code contribution. AS-02
386 files are now fully supported with some TODOs and two major
387 exceptions: LEAD indexes are not supported by the MXF writers
388 and interlace images are not yet supported.
389 o Added support for MCA labels (ST 428-12) to asdcp-wrap. Note
390 that this project is still in the early stages of interop testing
391 so errors are likely present and don't expect any server to
392 make use of this feature.

427 o Added support for 96 kHz files to blackwave.
428 o Added new path and string manglers to Kumu.
429 o Updated MCA ULs (I warned you...). Again please take some
430 time to proof this work against ST 477-4 including the latest
431 drafts of the registries.

433 MCALabelSubDescriptor
434 AudioChannelLabelSubDescriptor
435 SoundfieldGroupLabelSubDescriptor
436 GroupOfSoundfieldGroupsLabelSubDescriptor
437 GroupOfSoundfieldGroupsLinkID
438 Changed bytes 8 and and 13 of SoundfieldGroupLinkID

451 o Added missing zero-initializers to time values when parsing a
452 timestamp string (in the case where the optional [Thh:mm.[:ss]]
453 syntax is not present in an encoded string).
455 2012-03-06 - bug fixes, enhancements 1.9.45

465 labels (corresponds with publication of ST 429-2:2011).
466 o Exposed MXF object interface (MXF.h, Metadata.h) via ASDCP MXFReader
467 and MXFWriter classes.
468 o Added UL values from ST 377-4:2012. >>>>NOTE: These are preliminary
469 values, subject to change upon final publication of not only ST 377-4
470 but also the relevant registries. This is a good time to compare them
471 to the standard and complain if you think they are wrong!
472 o Added MCALabelSubDescriptor, AudioChannelLabelSubDescriptor,
473 SoundfieldGroupLabelSubDescriptor, and
474 GroupOfSoundfieldGroupsLabelSubDescriptor (from ST 377-4:2012) to
476 o Changed some internals to make MXFWriter::OPAtomHeader() work correctly.
477 o Split asdcp-test into several different programs to help relieve
478 the impenetrable-list-of-arguments problem. asdcp-wrap, asdcp-unwrap
479 and asdcp-info take the place of asdcp-test's -c, -x and -i options,
480 respectively. asdcp-util contains the remaining functions. Note that
481 asdcp-test is now DEPRECATED, new functionality and bug fixes will be
482 aimed at the new tools. Also note that some options and calling
483 conventions are different for the new tools as compared to asdcp-test.
484 Please read the synopses and make sure you understand the new idioms.
485 o asdcp-wrap has a new argument, -C <UL>, that writes the given UL to the
486 ChannelAssignment item in the WaveAudioDescriptor (only useful when
487 writing PCM essence).
490 2011-11-30 - bug fixes v1.8.44
491 o Corrected a wrong decryption UL selection when unwrapping MXF.
494 2011-10-27 - bug fixes v1.8.43
495 o Corrected broken Essence UL matching. (Thanks to Michael Loder).
498 2011-08-31 - bug fixes v1.8.42
499 o Added missing HFR support for PCM essence reader/writer.
502 2011-08-30 - bug fixes, enhancements v1.8.41
503 o UL version byte now ignored when comparing UL values.
504 o Changed the version byte in the TimedTextEssence UL to 0x01. There
505 is no published Essence Keys registry so it can't have a maintained
507 o JP2K Sequence Parser modified to skip directory entries that
508 are not files in the case where the parser is initialized with
509 a directory path. When initialized with a list of file names
510 this check is not performed. Based on a hint by Steve Quartly.
511 o Increased the size of the MPEG header parser buffer.
512 o Added missing FrameType() implementation to ASDCP::MPEG2::MXFReader.
513 o Added missing Close() implementations to MXF reader classes.
514 o Added missing Timestamp::Timestamp(const char* datestr) implementation.
515 (Thanks to Matt Sheby for this and the previous three items.)
516 o Fixed error in Kumu::FortunaRNG::FillRandom() that was returning the
517 end of the random buffer instead of the front (Thanks to Mike Radford).
518 o Added support for proposed sound channel format identifiers
519 '7.1DS' and 'WTF'. Optimistically chose version '0x0c'.
520 o Added support for stereoscopic images in JP2K files at edit
521 rates of 48, 50 and 60 eups (96, 100 and 120 fps).
524 2010.11.15 - bug fixes, enhancements v1.7.40
525 o Fixed bug in long KLV packet support (Thanks to Jim Radford).
526 o Fixed AvgBps in PCM files, *again*. Sorry for the crazy.
527 o More fixes and changes in support of 25, 30, 50, 60 fps.
528 (Thanks to Hans K. for the TC rate bug).
529 o Updated KLVFill UL version element to 0x02.
530 o Type change to support Xerces-C 3.x. (Thanks to Matt Sheby).
531 o Some internal API changes to KLV types. Does not affect
533 o Added NetworkLocator type to MXF metadata types.
534 o Added file offset display to klvwalk.
537 2010.09.09 - bug fixes, enhancements, v1.7.39
538 o Fixed bug in JP2K PictureDescriptor initialization in
539 JP2K::MXFReader::OpenRead() and JP2K::MXFSReader::OpenRead()
540 o Once again fiddling with AvgBbs. How can something so simple
541 be such a constant cause of trouble? Tested with 1-, 2- and
542 6-channel input Wav files.
543 o asdcp-test now accepts a directory name when making PCM
544 files (-c). The directory name should be the only filename
545 argument. All files in the directory must be Wav files
546 (mixed channel sizes OK). Files are sorted alphabetically by
547 filename. Hint: use numeric name infix to define order:
556 2010.07.20 - bug fixes, v1.6.37
557 o Fixed TimedTextResourceSubDescriptor UL value.
560 2010.06.16 - bug fixes, v1.6.36
561 o Added support for new Edit Rates to asdcp-test.cpp.
562 o Expanded timed-text file reader in asdcp-test.cpp.
563 o Fixed large BER value encoding (plaintext) and decoding
564 (plaintext and ciphertext). This feature was introduced in
566 o Fixed AvgBps value for multi-channel Wave input.
569 2010.05.13 - bug fixes, enhancements, v1.6.34
570 o ST 429-5 files have corrected ULs for DCTimedTextDescriptor and
571 GenericStream DataElement. Files made with previous versions of
572 the library are incompatible with this and future versions.
573 o Fixed File Package TrackNumber values. Th
575 o Added edit rate constants to AS_DCP.h (25, 30, 50, 60).
576 o Changed AudioDescriptor "SampleRate" element name to "EditRate"
577 to make it consistent with the other types.
578 o Now builds with XercesC 3.x.
579 o KM_memio.h has better const behavior.
580 o Fixed a bug in KM_memio.h string archiving.
583 2010.01.05 - bug fixes, enhancements, v1.5.32
584 o Re-fixed swapped Interop and SMPTE OP Atom UL values. The swap
585 introduced in v1.5.31 was done in error.
586 o Added -z,-Z options to asdcp-test (j2c parameter checking)
587 o Reformed jp2k-test as j2c-test, added help and list processing,
588 added to standard install target.
591 2009.12.31 - bug fixes, enhancements, v1.5.31
592 o Fixed swapped Interop and SMPTE OP Atom UL values.
593 o Added get_BER_length_for_value() subroutine.
594 o Modified ASDCP::h__Writer::WriteEKLVPacket() to allow larger BER
595 lengths for KLV packets larger than 16 MB. This was required to
596 support large font files in the SMPTE 429-5 implementation.
599 2009.11.06 - bug fixes, enhancements, v1.5.29
600 o Fixed a bug that could cause HMAC values to be incorrectly
601 stored in MXF files. Files created with versions of asdcplib
602 prior to this version may have incorrect HMAC values.
603 o Improved handing of XML files for MXF wrapping.
604 o Jpeg2000 codestream EditRate and SampleRate mismatches
605 now warns instead of returning an error.
606 o Improved error handling in Jpeg2000 sequence parsing routines.
607 o Added two methods to Kumu::Timestamp, AddSeconds(), to add (or
608 subtract) seconds to a time value, and GetSecondsSinceEpoch()
609 to get the number of seconds since the unix epoch.
610 o Added new option to asdcp-test, '-a', to specify a UUID when
612 o Added support for specifying the intrinsic duration of MXF files
613 containing timed text.
614 o Added new option to wavesplit, '-i', to display WAV file metadata.
617 2009.05.21 - bug fixes, v.1.4.24
618 o Fixed a bug that caused incorrect SubDescriptors UL values to be
619 written into interop format MXF track files. Note that this involved
620 a substantial reorganization of MXF internals. Please test thoroughly
621 in your application before using in production. Note that this is a
622 significant bug fix and track files created with 1.4.22 may be incompatible
626 2009.04.09 - SMPTE format fixes, enhancements and bug fixes, v.1.4.22
627 o asdcplib now uses GNU autotools on POSIX systems to configure
628 and build. See "./configure" for details. Note that two options,
629 --enable-freedist and --with-python are not enabled in the free
630 version of asdcplib and should not be used.
631 o Added build option (CONFIG_RANDOM_UUID) to enable mixed case UUID
632 generation when environment variable KM_USE_RANDOM_UUID is defined.
633 o Fixed a condition that could cause an error to occur when wrapping
634 SMPTE format timed text track files that do not define a starting
636 o Updated ULs for SMPTE format track files.
637 o SampleRate added to JP2K metadata
638 o Support for wrapping 96kHz WAV files added.
639 o Updated ULs for audio channel formats (ChannelFormat)
640 o Updated font subdescriptor MIME Types for TimedText Trackfiles.
641 o Changed time implementation to support dates beyond Jan 19th, 2038.
642 o Xerces-C XML parser support added.
643 o New build method for Windows (see win32/README.txt for details).
644 o Added new functionality in Kumu to recursively create and delete files
645 and directories, and get free disk space for a given volume path.
646 o Added a method to Kumu::Timestamp, AddMinutes(), to add (or subtract)
647 minutes to a time value.
648 o Improved how Kumu::Timestamp parses timestamps with offsets.
649 o Fixed a bug that caused incorrect HMAC values to be calculated.
652 2008.02.16 - SMPTE format fixes, bug fixes v.1.3.18
653 o Added correct SMPTE UL for StereoscopicPictureSubDescriptor.
654 o Exposed JP2K metadata parser as ParseMetadataIntoDesc().
655 o Added simple stereoscopic framebuffer to support paired ReadFrame()
656 and WriteFrame() methods (allows simpler integration with other
658 o Improved detection of JPEG Interop stereoscopic files.
659 o Win32 build fixes (Thanks to Mike Crowe at DTS).
660 o Added the WITH_MD macro to the makefile. Set this value to one
661 to build Win32 with /MD[d] instead of /MT[d].
662 o The Generic Container UL has been added to the EssenceContainers
663 set in the header partition pack for encrypted files. It has always
664 been there in plaintext files.
665 - Below this point the changes are internal and should not affect you
666 unless you use Kumu directly.
667 o Major refactoring of KM_log.[h|cpp].
668 o Fixed buffer re-sizing issue in Kumu::ByteString.
669 o Replaced type IdentifierList with ArchivableList.
670 o Added COPYING file to the release bundle.
673 2007.12.13 - Bug fixes v.1.2.17
674 o Changed Result_t implementation to use int instead of long, which
675 was causing trouble on some 64 bit platforms.
676 o Fixed EKLV HMAC. NOTE: Breaks backward compatibility with older
677 Interop files. To validate these files, use asdcplib-1.1.14. This
678 should not cause too much trouble since files with broken and
679 non-broken HMAC have been in the wild for years without issue.
680 o Fixed HMAC sequence numbering in encrypted stereoscopic files.
681 o Finished stereoscopic test targets in the makefile.
682 o Fixed the win32 build, now expects VS2005 compiler by default,
683 use WITH_VC6=1 top get VC6 flags.
684 o Stereoscopic and Timed Text modes now have SMPTE UL values.
685 NOTE: SMPTE 429-5 and 429-10 are not yet published. It is possible
686 that these UL values may change before publication. Please use
687 caution when using these features for production work.
688 o Changed a bunch of symbol names in the 429-5 implementation to
689 better match the spec.
690 o Added -U option to asdcp-test to dump the UL library to stdout.
691 o Fixed erroneous placement of the PictureEssenceCoding UL in JP2K
692 files (Interop and SMPTE modes).
695 2007.10.22 - Timed Text, Stereoscopic Picture and Bug fixes v.1.2.16
696 o Significant API changes have been made. Please read all entries
697 in this changelog to be sure you understand the changes. Also
698 note that some changes have been made to LS_MXF_SMPTE files that
699 are incompatible with earlier releases (e.g., EKLV HMAC). If
700 you are looking for a stable interop release, use v.1.1.14.
701 o Fixed RFC 2104 HMAC implementation for LS_MXF_SMPTE only. The
702 broken implementation has been maintained for Interop mode.
703 o Added support for draft SMPTE 429-5 Timed Text Track File. This
704 is still waiting for official SMPTE ULs, so do not use it for
705 shipping products. An XML parser is needed to create a Timed
706 Text Track File; Expat is now an optional part of the build.
707 Make with WITH_XML_PARSER=1 to link with Expat. If you do not
708 link with expat, you will get an error when using the TimedText::
709 DCSubtitleParser class. See also S429-5-cgi.cpp for an example
710 that shows how to serve plaintext MXF file elements directly via
712 o Added support for draft SMPTE 429-10 Stereoscopic Picture Track
713 File, including the JPEG Interop version. This is still waiting
714 for official SMPTE ULs, so do not use it with LS_MXF_SMPTE for
716 o Refactored the following files as a side-effect of the above
717 work: AS_DCP_JP2K.cpp AS_DCP_MPEG2.cpp AS_DCP_PCM.cpp
718 AS_DCP_MXF.cpp AS_DCP_internal.h MXF.[h|cpp] MXFTypes.[h|cpp]
719 Metadata.[h|cpp] h__Reader.cpp h__Writer.cpp klvwalk.cpp.
720 WARNING: While significant effort has been extended to make sure
721 that these changes do not affect existing stable file support,
722 users are cautioned to test this release thouroughly.
723 o Added a large set of filesystem path manglers to KM_fileio.h. See
724 path-test.cpp for example usage. The path manglers have not yet
725 been tested on win32 platforms (they are currently used only by
726 the Timed Text module.
727 o The PathIsFile(), PathIsDirectory() and FileSize() subroutines
728 have been modified to accept const std::string& instead of
730 o Added namespace and parsing support (Expat) to Kumu::XMLElement
731 (currently used only for Timed Text support). Also added some
733 o Altered MXF::UTF16String to use mbtowc() and wctomb().
736 2007.03.31 - Bug fixes v.1.1.14
737 o Fixed KeyFrameOffset value in MPEG wrapping to have negative
738 value. This is probably not yet complete for handling all
739 types of GOPs. Please send chunks of MPEG-2 VES that you
740 find which break this. Thanks to Doremi.
741 ** no other file format changes in this release **
742 o Fixed error in RIP interpretation when reading arbitrary (i.e.,
744 o Fixed a memory leak in ASDCP::MXF::OPAtomHeader when used
745 in read mode. Thanks to Mahesh Bajaj for pointing out this
746 bug and the one above.
747 o Removed asserts from KM_fileio, replaced with RESULT_WRITEFAIL
748 return value statements.
749 o Added -s and -p to the makefile install target.
750 o Altered ByteString behavior to use target Length() in copy
751 operations (instead of Capacity()).
752 o Added new Set() method to ByteString.
753 o Fixed a bug in ByteString::Unarchive() that caused the operation
754 to fail when the buffer was smaller than the read (i.e., when
755 Capacity() was called).
756 o Added IdentifierList class to KM_util.h.
757 o Changed some Error() messages to Debug() in Wav.cpp
758 o Revived jp2k-test.cpp and asdcp-mem-test.cpp (they both had
762 2007.02.15 - Bug fixes v1.1.13
763 o Removed 'VDescObj->SampleRate.Numerator = VDesc.FrameRate;'
764 from MPEG2_VDesc_to_MD() in AS_DCP_MPEG2.cpp, was line 76.
765 o Added KM_TEST_NULL_STR_L() and KM_TEST_NULL_L() macros to
766 KM_log.h. These versions log the location of the null value.
767 Macros are now used in any module that includes KM_log.h.
768 o MPEG2 VES with run of zero values at the head is now OK.
769 o Increased VESHeaderBufSize to 16K.
770 o Added makefile support for local OpenSSL in ../openssl, if
772 o The Kumu::PathIs*() functions now return false if a null or
773 empty string is given (used to be an assert).
774 o Cleaned up the install target in the makefile.
775 o Fixed SMPTE 429-6 HMAC -- FIPS 186-2 implementation was
776 laughably incorrect. Thanks to Doremi for pointing this out.
777 o Removed default parameter to HMACContext::InitKey().
778 o Cleaned up messages and CLI arg handling in asdcp-test.
781 2006.11.19 - Mo better stuff v1.1.12
782 o Changed read-only Result_t accessor methods to const.
783 o Added Base64 (-B) option to kmrandgen.
784 o Removed 16-bit alignment restriction from kmrandgen.
785 o Improved WAV file extraction speed (Thanks to Jim Radford
786 for pointing this out).
787 o Added single-channel split for WAV extraction (asdcp-test -1).
788 o Fixed remainder bug in h__RNG::fill_rand().
791 2006.11.03 - Bug fixes v1.1.11
792 o Increased index table entry list size to 5000.
793 o Added length checking to TLV writer (returns error if TLV
794 payload exceeds 64kB).
795 o Fixed partition header and RIP errors related to 2-partition
796 files (MXF Interop mode).
797 o Added -t option to asdcp-test (SHA-1 digest with Base64 output
799 o Fixed Sub Descriptor reference bug (Thanks to Denis Leconte
800 for dogged determination).
801 o Added directory-of-wav detection to RawEssenceType()
802 o Modified MXF::Partition::AddChildObject() to only generate
803 a UUID if the InstanceID is unset.
804 o Added ComponentMaxRef & ComponentMinRef to RGBAEssenceDescriptor.
806 o Added detection of 2K/4K jp2c, writing correct 4K metadata.
809 2006.10.05 - Bug fixes v1.1.10
810 o Changed RM_RELEASE to RL_RELEASE in MXFTypes.h.
811 o Changed the MXF writer to use RL_RELEASE (was RL_DEVELOPMENT).
812 o Really fixed source reference chain.
813 o Updated JP2K file package label.
814 o Changed location of JPEG2000PictureSubDescriptor in the
815 header (was erroneously before Preface).
816 o Altered LS_MXF_INTEROP to produce 2-partition files.
819 2006.09.25 - Bug fixes v1.1.9
820 o Fixed SourcePackageID value. All files will be 'original',
821 i.e. SourcePackageID will be all zeros. Let me know if you
822 want to set SourcePackageID.
823 o Fixed compiler warnings on some Linux platforms
824 o Fixed the build so that BUILD_DIR is no longer created
826 o Added duration detection to the raw essence parsers. The
827 MPEG parser uses a nasty approximation so don't use it
828 without paying close attention to the result.
829 o Modified PCMParserList to make it more useful as a base
831 o Fixed bugs and re-organized command-line help in asdcp-test
833 o Fixed two-partition file reads.
834 o Fixed Win32 PRNG initialization.
835 o Renamed asdcp-lf-test as kmfilegen.
836 o Added kmrandgen and kmuuidgen.
837 o Added string retrieval mechanism to Result_t.
838 o Refactored Kumu::Identifier and its sub-classes.
839 o Altered Kumu::PathIsFile to return true when the path
840 is a symbolic link (unix only).
841 o Altered Kumu::FileWriter::OpenWrite to use file creation
842 mode 0664 (was 0644) (unix only).
843 o Added Kumu::WriteStringIntoFile() subroutine.
846 2006.04.05 - Bug fixes and new stuff v1.1.7
847 o Fixed a bug in the MPEG parser that caused it to fail when
848 handling start codes spanning buffer boundaries
849 o Added wavesplit and blackwave utility programs
850 o Added support for revised SMPTE HMAC key derivation when
852 o Refactored platform compatibility and general utilities
853 into a new sub-library "Kumu". There are no new build
854 steps or dependencies, but some important things have
856 + Result_t is no longer an enum, it is now a class.
857 Library result codes are now declared as const objects
860 const Kumu::Result_t RESULT_FORMAT (-101, "The file...");
862 The macros ASDCP_SUCCESS and ASDCP_FAILURE still work
863 the same way thanks to an operator overload for type long.
864 See KM_error.h for more information.
865 + The logging interface has been moved out of AS_DCP.h
867 o Some of the command line utilities that were using headers
868 other than AS_DCP.h have been changed to use the Kumu
869 equivalents. If you have code based on those utilities, you
870 will have to update by hand.
871 o Added new types to the EssenceType_t enum.
872 o The guard macro for Win32 code has changed from WIN32 to
876 2006.03.2x - new stuff
877 o Proper handling of stream-id byte of essence UL values
878 o writes 3-partition files, reads 2-part or 3-part
881 2006.03.16 - bug fixes plus
882 o Removed SMPTE_LABELS compile-time option. The reader will now
883 silently accept either SMPTE or MXF Interop labels, the writer
884 can be instructed which to use at runtime. Default is Interop.
885 o Added an AIFF reader. Support is preliminary, it works with the
886 AIFF files I have on hand.
887 o More code refactoring. More to come.
890 2006.03.09 - full read-write
891 o Removed ASDCP_WITHOUT_OPENSSL compile-time option.
892 o Full read/write now working on new MXF library
895 2005.00.00 - A New Hope
896 o The temporary mxf-lite has been removed. MXF files are now
897 managed via the objects in KLV.h, MXFTypes.h MXF.h and
898 Metadata.h. This release does not support writing MXF files.
899 o Fixed a header interpretation error in the Wav parser.
902 2005.00.00 - The Reformation
903 o Removed mxflib as a dependency by forking the necessary
904 functions and placing them in the mxf-lite subdirectory.
905 Please note that the very heavy modifications done here
906 render all comparisson to mxflib code a substantial task.
907 All errors are now mine and users are warned not to bug
908 Oliver or Matt for help with this code. The version of
909 mxflib at the time of the fork was: 0.5.1.3.
912 2005.06.03 - bug fixes v0.10.18
913 o Updated UL batch to include GC UL.
916 2005.05.27 - bug fixes v0.10.17
917 o Un-did essence container and compression descriptor changes.
918 The default build reflects MXF Interop decisions as of 26 May.
919 o Added note about build versions to README (see above).
920 o Added warnings to SMPTE_LABELS builds.
921 o Fixed JP2K essence container label.
924 2005.05.02 - bug fixes v0.10.16
925 o Reorganized internal files, added file reader object, added OS
926 portability header, removed and renamed some files. If you have a
927 patch against previous versions of the source, you should check
929 o Added RGBA attributes to JP2K descriptor.
930 o Changed interface to CodestreamParser.
931 o Added JP2K parser implementation. It is parsing each frame but is
932 not yet being used to populate the descriptor.
933 o Added 48fps option for `asdcp-test -p`.
934 o Added picture rate constants to AS_DCP.h (23.976, 24, 48).
935 o Added sample rate constant to AS_DCP.h (48k).
936 o Changed asdcp-test to encrypt picture headers by default
937 (plaintext offset will be 0), added -E option to allow
941 2005.04.28 - bug fixes v0.9.15
942 o The XML descriptors for the crypto DMS have moved in mxflib to
943 the file DMS_Crypto.xml (they were in DMS_DCPENC.xml). Older
944 installations should update the file from mxflib.
945 o Added Close() and Seek() to ~MyFileWriter(), cleaned up headers
946 o Added UUID generator output mode (-u).
947 o Added -S option to extract PCM essence into stereo wav files
948 o Added more UL testing and conformance checking.
949 o Added macro SMPTE_LABELS which causes the library to be built
950 with SMPTE (as opposed to MXF Interop) labels. This is not
951 set by default, and currently only affects the PCM container
952 label and encrypted element label.
953 o Cleaned up the GNUmakefile test targets, the source files
954 are now named with the TEST_FILE_PREFIX macro.
955 o enabled 23.976-framed PCM (2002 samples per frame)
956 o The size of the asdcp-test frame buffer for picture essence
957 may now be set from the command line (-b). The default is 4MB.
958 o h__Reader::ReadEKLVPacket() now tests the UL (duh) and switches
959 on the value, allowing plaintext and ciphertext frames to
960 be mixed in the file.
961 o Fixed error in UUID generator format.
962 o JP2K files now use the GenericPictureDescriptor to store
963 ContainerDuration and SampleRate. SampleRate is mapped
964 to EditRate in the PictureDescriptor struct. This fixes
965 the second caveat from the 0.8.13 release.
966 o Fxed bug in PCMParserList that was miscalculating the extent
967 of a PCM sample. This bug did not affect API users, it was
968 only present in asdcp-test.
969 o Fixed EditRate on PCM files (was showing sample rate)
970 o Fixed Encrypted Essence Container UL
971 o Fixed BlockAlign value for PCM essence
973 - The following changes were provided by Jeff Loewenguth
975 o Moved the DMS CryptographicFramework entry from the material
976 package to the source package
977 o Fixed erroneous Source Essence Container Label value
978 o Fixed broken sort of JP2K frames in JP2K parser
979 o Added FindFrameGOPStart() method to the MPEG2 MXFReader
980 o Added missing length values for EKLV packets without HMAC
981 o -x with JP2K essence writes to files with 6 digit names
983 o The Key ID may now be specified as an argument to asdcp-test
987 2004.12.30 - bug fixes + wav files v0.8.14
988 o Added WAV file write to asdcp-test (uses mxflib::waveheader_t).
989 o Three-partition files reading properly. adscplib still writes
991 o Changes in the mxflib WAV essence parser API had broken
992 asdcplib's ability to read essence from a WAV file. I have
993 fixed this bug, but at the expense of breaking compatibility
994 with older versions of mxflib. Beware!
995 o Removed redundant (but working) bin-text-bin conversions.
998 2004.12.23 - JPEG 2000 support v0.8.13
999 o Reads/writes JPEG 2000 essence in plaintext and ciphertext
1000 with the following caveats:
1001 - The Picture Essence Descriptor is empty.
1002 - Because there is no essence descriptor, the reader code
1003 in asdcp-test has no idea how many frames are in the file
1004 and ends with an out-of-bounds frame error. This error
1005 is being suppressed in asdcp-test for the current release.
1006 o Still broken when reading three-partition files.
1009 2004.10.22 - fixes and UL updates v0.7.11
1010 WARNING: COMPATIBILITY BREAKPOINT
1011 Files created with this and future versions of this library are
1012 not compatible with previous versions of this library. As you
1013 might suspect, files created with previous versions of this
1014 library are not compatible with this and future versions.
1016 o h__Reader will now open a three-partitition file (untested)
1017 o Moved DMS from Material partition to File partition
1018 o Added length fields to appropriate places in EKLV packet
1021 2004.10.22 - fixes and UL updates v0.7.10
1022 o fixed frame buffer handling of externally allocated buffer,
1023 created unit test (asdcp-mem-test)
1024 o added operator==() and operator!=() to Rational type
1025 o fixed some type-related compiler warnings
1026 o asdcp-test -p now works on unwrap
1027 o updated some ULs to match documentation (thanks to Arun
1029 o canonicalized line endings
1032 2004.07.02 - full plaintext + ciphertext read/write v0.6.9
1033 o HMAC, plaintext offest and raw ciphertext read supported
1034 o back to proper CBR index
1035 o MPEG temporal offset working
1038 2004.07.01 - plaintext + ciphertext read/write v0.5.8
1039 o encryption of MPEG and PCM essence supported with the
1042 - no plaintext offest support
1043 - no raw ciphertext read support
1044 o moved to reflecting the whole KLV triplet in the CBR
1045 index (now incompatible with mxflib, still searching
1046 for info about what's "right")
1047 o awaitng the following fixes/features:
1048 - retrieve Temporal Offset from index in MPEG2::Reader
1049 - test for correct ULs when reading frame triplets
1050 - fix header metadata items for encrypted files
1052 - plaintext offest support
1053 - raw ciphertext read support
1056 2004.06.14 - plaintext read/write w/key generator v0.4.5
1057 o Project now uses OpenSSL (tested with 0.9.7d on win32, Linux, Darwin)
1058 Use `make ASDCP_WITHOUT_OPENSSL=1` to make plaintext-only version
1059 o Accepts interior I frames when parsing MPEG2 VES
1060 o Improved error reporting on format errors
1061 o Added support for encryption to asdcp-test
1062 o Added RNG for asdcp-test (non-production use only, see notes in FortunaRNG.h)
1063 o Implemented CBC encrypt, decrypt module
1064 o Added partial TemporalOffset retrieval from MPEG2 parser
1065 o Fixed win32 binmode bug
1068 2004.05.12 - plaintext read/write v0.3.4
1069 o Full read/write of plaintext MPEG-2 VES and WAV files
1070 (does not yet support mux from or demux to 2 channel pairs)
1071 o Builds with autoconf-based mxflib
1072 o Added ASDCP_ prefix to macros
1073 o Updated documentation, fixed documentation errors
1074 o Simplified API for MXF writer setup
1075 o Decoupled essence parsers from MXF writers
1076 o added raw ciphertext support to FrameBuffer
1077 o Cleaned up Get/Set naming confusion
1078 o Added missing const qualifiers
1081 2004.04.27 - preview release v0.2.1
1082 o hasty release for quick review
1083 o this release may not build with mxflib using autoconf.
1084 o writes plaintext AS-DCP MPEG2 essence files
1085 o tested under win32 and linux. FreeBSD and Darwin do not work
1088 2004.02.04 - First release (v0.1.1):
1089 o asdcp-test is mostly complete. It should correctly provide
1090 access to the read and info capabilities of the library.
1091 o The MPEG2 reader is functional but not fully tested.
1092 o Some file format integrity tests remain to be coded.
1093 o The PCM reader is mostly complete, I am having difficulty
1094 getting a suitable test file from mxfwrap.
1095 o The makefile creates a static library module. The API
1096 will cleanly support a DSO (or DLL). Let me know if DSO
1097 support is important to you.
1098 o Nothing is thread safe. Thread safety was not a requirement
1099 in the initial project definition. Thread safety may be added
1100 above the mxflib/klvlib level. Let me know if it is important
1102 o The files xmldict.xml and types.xml must be in the current
1103 directory when the program is run. The files are supplied
1104 with mxflib. Runtime location of the files is not currently
1105 a project goal. Comments on how best to handle this situation
1106 would be appreciated. See AS_DCP.cpp at init_mxf_types()
1107 for a more detailed discussion.
