Change History
2020-02-10 - 2.10.35 -- HTJ2c support, minor extensions, bug fixes
o Support for wrapping High-Throughput j2c contrinuted by Pierre Lemieux.
o Added support for DisplayType, IntrinsicPictureResolution, ZPositionInUse
properties in timed text track files.
o Merged bug fixes and minor extensions from contibutors, see git log for detail.
o Updated to ACES writer to add a ContainerConstraintsSubDescriptor (mandatory
per ST 379-2)
o Add MCA labels for Sign Language Video Stream.
2019-02-22 - 2.10.32 -- bug fixes
o Fixed parsing of as-02-wrap -tfr (ACES) option value
o Fixed ISXD bugs:
o Incorrect UTF_8_Text_DataEssenceCoding UL
o Incorrect ISXDDataEssenceDescriptor_NamespaceURI UL
o Incorrect use of FrameWrappedISXDData UL
o Incorrect use of FrameWrappedISXDContainer UL
o Added wide-char support for filenames on Win32, allows UTF-8 characters in
calls to Kumu::File*::Open*(). The macro KM_WIN32_UTF8 must be defined to
enable this feature.
o CMake fixed to extract version form configure.ac
2018-10-15 - 2.10.31
o NOTE: Use of MXFGCGenericEssenceMultipleMappings in AS-02 files is not
defined by standards and will soon be withdrawn from this library. If you
would like to experience this change now, define the macro
ASDCP_GCMULTI_PATCH
o Removed PIMD support (unused prototype)
o Returned the DataEssenceCoding UL version byte to "5" in Atmos files
o Fixed ColorPrimaries_ACES UL version byte
o Added "FSKSync" audio channel label to the MCA label generator
o SMPTE RDD 45 requires a minimum BER encoding length of five (5) bytes for
Content Element packets. The Write_EKLV_Packet() API has been modified to
allow the specification of this value. All existing wrapping modules have
been changed to conform to the new API, and all continue to use four (4)
as the minimum BER encoding length. Write_EKLV_Packet() will continue to
generate BER encodings with a length greater than the specified minimum for
payloads that are larger than values encoded using the specified minimum.
2018-09-14 - 2.9.30
o Fixes wrong MajorVersion in Preface
o Adds VideoLineMap also to RGBA essence descriptor
o Adds VideoLineMap to RGBA and CDCI descriptor only when option -l
is present (disputable - but distinguished value {0, 0} is not
allowed in closed and complete partitions)
o Fixes issue with IndexRate not set in AS-02 J2K files
o Additional fixes to minor version number in AS-02 partition packs
o CMake brought up to date
o Fixed erroneous WAV RF64 header interpretation
o ACES AS-02 ST 2065-5 wrapper
o ACES AS-02 ST 2065-5 unwrapper
o ST 2067-50 Subdescriptors support
o ST 2067-50 Target Frame wrapping support
o ST 2067-50 Target Frame unwrapping support
o Command line tools as-02-wrap, as-02-unwrap and as-02-info extended to
support ACES, App#5 subdescriptors and Target Frames
o Beta support for ST2065-5 AS_02 ACES wrapping and unwrapping including
ST 2067-50 Subdescriptors and Target Frame support
o Please report ACES-related issues to wolfgang.ruppel@hs-rm.de
2018-08-08 - 2.8.29
o Modified AS_02::ST2052_TextParser::OpenRead signature
o Fixed partition version error in AS-02 interior body partitions
o Changed StartTimecode to 0 (zero) in the Source Package
o Remove use of BN_init in OpenSSL API
o XML parser now works correctly with Xerces-c 3.x
o Improved MCA sound field expression parser
o Added support for IMF Numbered Source Channel labels in MCA
o Added CLI switches for MCAAudioContentKind and MCAAudioElementKind
o Re-assigned asdcp-wrap option '-g' to '-x', added new option '-g'
o Added TLM marker check to j2c-test
o Added to kmrandgen options '-C', '-w', '-W'
o Added support for SMPTE RDD 47 "ISXD Track File"
o Added generic support for SMPTE RP 2057 "Text-Based Metadata Carriage in MXF"
o Re-factored AS-02 frame-wrap index write to use a common implementation
o Re-factored support for SMPTE ST 410 to use a common implementation (affects
AS-DCP and AS-02 timed-text MXF (SMPTE 429-5)
o Patched several ambiguous integer casts.
o Added new essence type identifiers ESS_AS02_ISXD and ESS_AS02_ACES
o Fixed a bug wherein the Generic Container data track clip was instead being
written as a DM track
o Fixed UL values DCDataDescriptor and ContainerConstraintSubDescriptor to have
a byte 6 value of 0x53 (Tag Set) instead of 0x07 (coding sentinel)
o Added UL values 468 - 511 to the dictionary (including added ACES UL values)
o Added ApplicationSchemes and ConformsToSpecifications to the Preface set
o Added default initializer to MXF::LineMapPair
o Added sets DescriptiveFramework, DescriptiveObject, TextBasedDMFramework,
TextBasedObject, GenericStreamTextBasedSet and ISXDDataEssenceDescriptor,
ACESPictureSubDescriptor, TargetFrameSubDescriptor
o Added ISXD support, options '-c', '-g', '-G', '-v', '-q', '-u' to as-02-wrap
o Added ISXD support and option '-g' to as-02-unwrap
o Cleaned up definition of UL WaveAudioDescriptor_PeakEnvelopeData (currently
unused)
o Moved ReferenceAudioAlignmentLevel from WaveAudioDescriptor to
GenericSoundEssenceDescriptor
2016-12-10 - MDD bug fix 2.7.19
o The previous version (2.7.18) contained incorrect MDD.cpp and MDD.h
files which affect the PIMF and JP2KEssenceCompression labels.
2016-12-10 - bug fixes 2.7.18
o Fixed *all* Partiton version numbers in AS-02 files (the previous attempt
only affected the header partition)
o Improved IMSC-1 profile detection. May not yet be perfect, experimentation
encouraged!
o Added IMF App2e UL values and new MXF data types ColorPrimary and
ThreeColorPrimaries (contributed by Schleich)
o Added picture descriptor elements MasteringDisplayPrimaries,
MasteringDisplayWhitePointChromaticity, MasteringDisplayMaximumLuminance,
and MasteringDisplayMinimumLuminance
o Added -o and -O options to as-02-wrap
o Fixed as-02-wrap option -p when making 4:4:4 files
o Simplified as-02-wrap syntax description
2016-12-01 - bug fixes 2.6.17
o Fixed Partiton and Preface version numbers in AS-02 files
o Replaced WIN32 directory scanner with dirent_win.h
o The NamespaceURI property of AS-02 timed text files has been exposed in the API
and via as-02-wrap -P. This behavior replaces previous bad behavior, but puts
responsibility for selecting the correct value on the operator.
o Exposed CreatePNGNameId and CreateFontNameId subroutines in AS_02::TimedText
o Adjusted UUID generation based on PNG and font names to exclude paths by
inserting a call to PathBasename at each Id generation site
o Fixed AS-02 timed text index partition
o Fixed contents of generic partiton EssenceContainers property in AS-DCP timed
text files
o Added PixelLayout to RGBAEssenceDescriptor (contributed by Schleich)
o Cleared up MXFGCP1FrameWrappedPictureElement / MXFGCP1FrameWrappedPictureElement
ambiguity. PHDR continues to use MXFGCP1FrameWrappedPictureElement.
MXFGCI1FrameWrappedPictureElement is supported for interlace.
o Added support for 192, 200 and 240 fps images, includes 96, 100 and 120 fpe stereo

o Added prototype PIDM dynamic metadata wrapping, config with --enable-phdr
(Not for production use, caveat emptor, not the droids, etc.)
2016-08-11 - bug fixes, 2.5.15
o Modified as-02-wrap to pass WhiteRefLev, BlackRefLev and ColorRange
(contributed by Elmer Musser / Rod Bogart)

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

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

metadata (Thanks to Mike Radford).
o Added new options to as-02-wrap.
2014-01-06 – Additional IMF/AS-02 support, bug fixes 2.1.1
o Fixed missing-index-partion bugs for AS-02 files.
o Moved LocalFilenameResolver into the AS_DCP public API so that it
can be used by other modules including AS-02.
o Did further refactoring of AS-02 Writer classes to separate CBR
and VBR indexing implementations.
o Fixed wave wrapping UL in clip-wrapped AS-02 files. Renamed some
UL constants to reflect "clip" or "frame" wrapping.

with GenericPictureEssenceDescriptor objects.
o Fixed a bug that was suppressing PictureComponentSizing,
CodingStyleDefault and QuantizationDefault when writing the
essence descriptor in a JP2K file (AS-DCP and AS-02).

o Improved integration of ST 377-4 MCA concepts with ST 429-2 static
labels.
o Modified asdcp-wrap to assume -L when wrapping timed-text (since
there is no MXF text wrapping for Interop.)
o Added new EssenceType_t values for IMF/AS-02 track files.
o Added detection for AS-02 track files to ASDCP::EssenceType()
o Changed lots of "const char*" to "const std::string&" in the
APIs defined by KM_fileio.h and AS_DCP.h.
o Fixed VBR Delta Segment entries to correctly flag progressive
material.
o Fixed PCM unwrapping bugs in as-02-unwrap.

(thanks to Stephane W)
2013-07-02 – IMF/AS-02 support, bug fixes 2.0.0
o Massive refactoring of internals to allow easier implementation
of AS-02. Some API changes were made as well (note that
OPAtomHeader is now OP1aHeader and RIP is no longer part of the
OP1aHeader.) If you are using this project as a library (and
especially if you are keeping patches against it) PLEASE TAKE
TIME TO EVALUATE THIS RELEASE THOUROUGHLY BEFORE ADDING IT TO
YOUR RELEASE PATH.
o Final integration of Fraunhoffer IIS code contribution. AS-02
files are now fully supported with some TODOs and two major
exceptions: LEAD indexes are not supported by the MXF writers
and interlace images are not yet supported.
o Added support for MCA labels (ST 428-12) to asdcp-wrap. Note
that this project is still in the early stages of interop testing
so errors are likely present and don't expect any server to
make use of this feature.
2013-07-01 - Bug fixes, enhancements 1.12.50
o Fixed missing return statement in ArchivableString::ArchiveLength
(thanks to both Kristof Provost and Franck Chopin)

2013-02-20 - bug fixes, enhancements 1.10.48
o Refactored internals of the AS-DCP file readers. While no
changes in behavior are intended, users are cautioned to test
thouroughly before use in production.
o Fixed a bug in ReadAncillaryResource that was causing bogus HMAC
failures when reading resources from a file.
o Fixed premature-release bug in the Expat version of the XML parser.
Thanks to Carsten Feldheim (IIS) for the tip.

PictureEssenceCoding property when wrapping JP2K files.)
o Added support for 96 kHz files to blackwave.
o Added new path and string manglers to Kumu.
o Updated MCA ULs (I warned you...). Again please take some
time to proof this work against ST 477-4 including the latest
drafts of the registries.
Changed the version byte (8 0f 16) to 0x0e:
MCALabelSubDescriptor
AudioChannelLabelSubDescriptor
SoundfieldGroupLabelSubDescriptor
GroupOfSoundfieldGroupsLabelSubDescriptor
GroupOfSoundfieldGroupsLinkID
Changed bytes 8 and and 13 of SoundfieldGroupLinkID
Added items to the UL dictionary:
MCAPartitionKind
MCAPartitionNumber

MCATitleVersion
MCATitleSubVersion
MCAEpisode
MCAAudioContentKind
MCAAudioElementKind
2012-08-07 - bug fix, 1.10.46
o Added missing zero-initializers to time values when parsing a
timestamp string (in the case where the optional [Thh:mm.[:ss]]
syntax is not present in an encoded string).
2012-03-06 - bug fixes, enhancements 1.9.45
o Removed ASDCP::Timestamp, all items that were of that class are now
of class Kumu::Timestamp
o Refactored Kumu::Timestamp to use KM_tai for internal representation
(replaced public Y M D, h, m, s variables)
o Refactored Kumu::Timestamp to use KM_tai for WIN32 builds
o Added UTC offset awareness to Kumu::Timestamp
o Replaced "long GetSecondsSinceEpoch(void) const" with
"ui64_t GetCTime() const"
o Corrected UL version segment in "7.1 DS" and "WTF" audio format
labels (corresponds with publication of ST 429-2:2011).
o Exposed MXF object interface (MXF.h, Metadata.h) via ASDCP MXFReader
and MXFWriter classes.
o Added UL values from ST 377-4:2012. >>>>NOTE: These are preliminary
values, subject to change upon final publication of not only ST 377-4
but also the relevant registries. This is a good time to compare them
to the standard and complain if you think they are wrong!
o Added MCALabelSubDescriptor, AudioChannelLabelSubDescriptor,
SoundfieldGroupLabelSubDescriptor, and
GroupOfSoundfieldGroupsLabelSubDescriptor (from ST 377-4:2012) to
Metadata.h
o Changed some internals to make MXFWriter::OPAtomHeader() work correctly.
o Split asdcp-test into several different programs to help relieve
the impenetrable-list-of-arguments problem. asdcp-wrap, asdcp-unwrap
and asdcp-info take the place of asdcp-test's -c, -x and -i options,
respectively. asdcp-util contains the remaining functions. Note that
asdcp-test is now DEPRECATED, new functionality and bug fixes will be
aimed at the new tools. Also note that some options and calling
conventions are different for the new tools as compared to asdcp-test.
Please read the synopses and make sure you understand the new idioms.
o asdcp-wrap has a new argument, -C <UL>, that writes the given UL to the
ChannelAssignment item in the WaveAudioDescriptor (only useful when
writing PCM essence).
2011-11-30 - bug fixes v1.8.44
o Corrected a wrong decryption UL selection when unwrapping MXF.
2011-10-27 - bug fixes v1.8.43
o Corrected broken Essence UL matching. (Thanks to Michael Loder).
2011-08-31 - bug fixes v1.8.42
o Added missing HFR support for PCM essence reader/writer.
2011-08-30 - bug fixes, enhancements v1.8.41
o UL version byte now ignored when comparing UL values.
o Changed the version byte in the TimedTextEssence UL to 0x01. There
is no published Essence Keys registry so it can't have a maintained
version number.
o JP2K Sequence Parser modified to skip directory entries that
are not files in the case where the parser is initialized with
a directory path. When initialized with a list of file names
this check is not performed. Based on a hint by Steve Quartly.
o Increased the size of the MPEG header parser buffer.
o Added missing FrameType() implementation to ASDCP::MPEG2::MXFReader.
o Added missing Close() implementations to MXF reader classes.
o Added missing Timestamp::Timestamp(const char* datestr) implementation.
(Thanks to Matt Sheby for this and the previous three items.)
o Fixed error in Kumu::FortunaRNG::FillRandom() that was returning the
end of the random buffer instead of the front (Thanks to Mike Radford).
o Added support for proposed sound channel format identifiers
'7.1DS' and 'WTF'. Optimistically chose version '0x0c'.
o Added support for stereoscopic images in JP2K files at edit
rates of 48, 50 and 60 eups (96, 100 and 120 fps).
2010.11.15 - bug fixes, enhancements v1.7.40
o Fixed bug in long KLV packet support (Thanks to Jim Radford).
o Fixed AvgBps in PCM files, *again*. Sorry for the crazy.
o More fixes and changes in support of 25, 30, 50, 60 fps.
(Thanks to Hans K. for the TC rate bug).
o Updated KLVFill UL version element to 0x02.
o Type change to support Xerces-C 3.x. (Thanks to Matt Sheby).
o Some internal API changes to KLV types. Does not affect
operation.
o Added NetworkLocator type to MXF metadata types.

2010.09.09 - bug fixes, enhancements, v1.7.39
o Fixed bug in JP2K PictureDescriptor initialization in
JP2K::MXFReader::OpenRead() and JP2K::MXFSReader::OpenRead()
o Once again fiddling with AvgBbs. How can something so simple
be such a constant cause of trouble? Tested with 1-, 2- and
6-channel input Wav files.
o asdcp-test now accepts a directory name when making PCM
files (-c). The directory name should be the only filename
argument. All files in the directory must be Wav files
(mixed channel sizes OK). Files are sorted alphabetically by
filename. Hint: use numeric name infix to define order:
my_movie_00_L.wav
my_movie_01_R.wav
my_movie_02_C.wav
my_movie_03_LFE.wav
my_movie_04_LS.wav
my_movie_05_RS.wav
2010.07.20 - bug fixes, v1.6.37
o Fixed TimedTextResourceSubDescriptor UL value.
2010.06.16 - bug fixes, v1.6.36
o Added support for new Edit Rates to asdcp-test.cpp.
o Expanded timed-text file reader in asdcp-test.cpp.
o Fixed large BER value encoding (plaintext) and decoding
(plaintext and ciphertext). This feature was introduced in
v1.5.31).
o Fixed AvgBps value for multi-channel Wave input.
2010.05.13 - bug fixes, enhancements, v1.6.34
o ST 429-5 files have corrected ULs for DCTimedTextDescriptor and
GenericStream DataElement. Files made with previous versions of
the library are incompatible with this and future versions.
o Fixed File Package TrackNumber values. Th
anks to Sankar.
o Added edit rate constants to AS_DCP.h (25, 30, 50, 60).
o Changed AudioDescriptor "SampleRate" element name to "EditRate"
to make it consistent with the other types.
o Now builds with XercesC 3.x.
o KM_memio.h has better const behavior.
o Fixed a bug in KM_memio.h string archiving.
2010.01.05 - bug fixes, enhancements, v1.5.32
o Re-fixed swapped Interop and SMPTE OP Atom UL values. The swap
introduced in v1.5.31 was done in error.
o Added -z,-Z options to asdcp-test (j2c parameter checking)
o Reformed jp2k-test as j2c-test, added help and list processing,
added to standard install target.
2009.12.31 - bug fixes, enhancements, v1.5.31
o Fixed swapped Interop and SMPTE OP Atom UL values.
o Added get_BER_length_for_value() subroutine.
o Modified ASDCP::h__Writer::WriteEKLVPacket() to allow larger BER
lengths for KLV packets larger than 16 MB. This was required to
support large font files in the SMPTE 429-5 implementation.
2009.11.06 - bug fixes, enhancements, v1.5.29
o Fixed a bug that could cause HMAC values to be incorrectly
stored in MXF files. Files created with versions of asdcplib
prior to this version may have incorrect HMAC values.
o Improved handing of XML files for MXF wrapping.
o Jpeg2000 codestream EditRate and SampleRate mismatches
now warns instead of returning an error.
o Improved error handling in Jpeg2000 sequence parsing routines.
o Added two methods to Kumu::Timestamp, AddSeconds(), to add (or
subtract) seconds to a time value, and GetSecondsSinceEpoch()
to get the number of seconds since the unix epoch.
o Added new option to asdcp-test, '-a', to specify a UUID when
creating MXF files.
o Added support for specifying the intrinsic duration of MXF files
containing timed text.
o Added new option to wavesplit, '-i', to display WAV file metadata.
2009.05.21 - bug fixes, v.1.4.24
o Fixed a bug that caused incorrect SubDescriptors UL values to be
written into interop format MXF track files. Note that this involved
a substantial reorganization of MXF internals. Please test thoroughly
in your application before using in production. Note that this is a
significant bug fix and track files created with 1.4.22 may be incompatible
with other systems.
2009.04.09 - SMPTE format fixes, enhancements and bug fixes, v.1.4.22
o asdcplib now uses GNU autotools on POSIX systems to configure
and build. See "./configure" for details. Note that two options,
--enable-freedist and --with-python are not enabled in the free
version of asdcplib and should not be used.
o Added build option (CONFIG_RANDOM_UUID) to enable mixed case UUID
generation when environment variable KM_USE_RANDOM_UUID is defined.
o Fixed a condition that could cause an error to occur when wrapping
SMPTE format timed text track files that do not define a starting
frame.
o Updated ULs for SMPTE format track files.
o SampleRate added to JP2K metadata
o Support for wrapping 96kHz WAV files added.
o Updated ULs for audio channel formats (ChannelFormat)
o Updated font subdescriptor MIME Types for TimedText Trackfiles.
o Changed time implementation to support dates beyond Jan 19th, 2038.
o Xerces-C XML parser support added.
o New build method for Windows (see win32/README.txt for details).
o Added new functionality in Kumu to recursively create and delete files
and directories, and get free disk space for a given volume path.
o Added a method to Kumu::Timestamp, AddMinutes(), to add (or subtract)
minutes to a time value.
o Improved how Kumu::Timestamp parses timestamps with offsets.
o Fixed a bug that caused incorrect HMAC values to be calculated.
2008.02.16 - SMPTE format fixes, bug fixes v.1.3.18
o Added correct SMPTE UL for StereoscopicPictureSubDescriptor.
o Exposed JP2K metadata parser as ParseMetadataIntoDesc().
o Added simple stereoscopic framebuffer to support paired ReadFrame()
and WriteFrame() methods (allows simpler integration with other
single-buffer code).
o Improved detection of JPEG Interop stereoscopic files.
o Win32 build fixes (Thanks to Mike Crowe at DTS).
o Added the WITH_MD macro to the makefile. Set this value to one
to build Win32 with /MD[d] instead of /MT[d].
o The Generic Container UL has been added to the EssenceContainers
set in the header partition pack for encrypted files. It has always
been there in plaintext files.
- Below this point the changes are internal and should not affect you
unless you use Kumu directly.
o Major refactoring of KM_log.[h|cpp].
o Fixed buffer re-sizing issue in Kumu::ByteString.
o Replaced type IdentifierList with ArchivableList.
o Added COPYING file to the release bundle.
2007.12.13 - Bug fixes v.1.2.17
o Changed Result_t implementation to use int instead of long, which
was causing trouble on some 64 bit platforms.
o Fixed EKLV HMAC. NOTE: Breaks backward compatibility with older
Interop files. To validate these files, use asdcplib-1.1.14. This
should not cause too much trouble since files with broken and
non-broken HMAC have been in the wild for years without issue.
o Fixed HMAC sequence numbering in encrypted stereoscopic files.
o Finished stereoscopic test targets in the makefile.
o Fixed the win32 build, now expects VS2005 compiler by default,
use WITH_VC6=1 top get VC6 flags.
o Stereoscopic and Timed Text modes now have SMPTE UL values.
NOTE: SMPTE 429-5 and 429-10 are not yet published. It is possible
that these UL values may change before publication. Please use
caution when using these features for production work.
o Changed a bunch of symbol names in the 429-5 implementation to
better match the spec.
o Added -U option to asdcp-test to dump the UL library to stdout.
o Fixed erroneous placement of the PictureEssenceCoding UL in JP2K
files (Interop and SMPTE modes).
2007.10.22 - Timed Text, Stereoscopic Picture and Bug fixes v.1.2.16
o Significant API changes have been made. Please read all entries
in this changelog to be sure you understand the changes. Also
note that some changes have been made to LS_MXF_SMPTE files that
are incompatible with earlier releases (e.g., EKLV HMAC). If
you are looking for a stable interop release, use v.1.1.14.
o Fixed RFC 2104 HMAC implementation for LS_MXF_SMPTE only. The
broken implementation has been maintained for Interop mode.
o Added support for draft SMPTE 429-5 Timed Text Track File. This
is still waiting for official SMPTE ULs, so do not use it for
shipping products. An XML parser is needed to create a Timed
Text Track File; Expat is now an optional part of the build.
Make with WITH_XML_PARSER=1 to link with Expat. If you do not
link with expat, you will get an error when using the TimedText::
DCSubtitleParser class. See also S429-5-cgi.cpp for an example
that shows how to serve plaintext MXF file elements directly via
HTTP.
o Added support for draft SMPTE 429-10 Stereoscopic Picture Track
File, including the JPEG Interop version. This is still waiting
for official SMPTE ULs, so do not use it with LS_MXF_SMPTE for
shipping products.
o Refactored the following files as a side-effect of the above
work: AS_DCP_JP2K.cpp AS_DCP_MPEG2.cpp AS_DCP_PCM.cpp

WARNING: While significant effort has been extended to make sure
that these changes do not affect existing stable file support,
users are cautioned to test this release thouroughly.
o Added a large set of filesystem path manglers to KM_fileio.h. See
path-test.cpp for example usage. The path manglers have not yet
been tested on win32 platforms (they are currently used only by
the Timed Text module.
o The PathIsFile(), PathIsDirectory() and FileSize() subroutines
have been modified to accept const std::string& instead of
const char*.
o Added namespace and parsing support (Expat) to Kumu::XMLElement
(currently used only for Timed Text support). Also added some
new accessors.
o Altered MXF::UTF16String to use mbtowc() and wctomb().
2007.03.31 - Bug fixes v.1.1.14
o Fixed KeyFrameOffset value in MPEG wrapping to have negative
value. This is probably not yet complete for handling all
types of GOPs. Please send chunks of MPEG-2 VES that you
find which break this. Thanks to Doremi.
** no other file format changes in this release **
o Fixed error in RIP interpretation when reading arbitrary (i.e.,
non-MXF) files.
o Fixed a memory leak in ASDCP::MXF::OPAtomHeader when used
in read mode. Thanks to Mahesh Bajaj for pointing out this
bug and the one above.
o Removed asserts from KM_fileio, replaced with RESULT_WRITEFAIL
return value statements.
o Added -s and -p to the makefile install target.
o Altered ByteString behavior to use target Length() in copy
operations (instead of Capacity()).
o Added new Set() method to ByteString.
o Fixed a bug in ByteString::Unarchive() that caused the operation
to fail when the buffer was smaller than the read (i.e., when
Capacity() was called).
o Added IdentifierList class to KM_util.h.
o Changed some Error() messages to Debug() in Wav.cpp
o Revived jp2k-test.cpp and asdcp-mem-test.cpp (they both had
stale #includes).
2007.02.15 - Bug fixes v1.1.13
o Removed 'VDescObj->SampleRate.Numerator = VDesc.FrameRate;'
from MPEG2_VDesc_to_MD() in AS_DCP_MPEG2.cpp, was line 76.
o Added KM_TEST_NULL_STR_L() and KM_TEST_NULL_L() macros to
KM_log.h. These versions log the location of the null value.
Macros are now used in any module that includes KM_log.h.
o MPEG2 VES with run of zero values at the head is now OK.
o Increased VESHeaderBufSize to 16K.
o Added makefile support for local OpenSSL in ../openssl, if
present.
o The Kumu::PathIs*() functions now return false if a null or
empty string is given (used to be an assert).
o Cleaned up the install target in the makefile.
o Fixed SMPTE 429-6 HMAC -- FIPS 186-2 implementation was
laughably incorrect. Thanks to Doremi for pointing this out.
o Removed default parameter to HMACContext::InitKey().
o Cleaned up messages and CLI arg handling in asdcp-test.
2006.11.19 - Mo better stuff v1.1.12
o Changed read-only Result_t accessor methods to const.
o Added Base64 (-B) option to kmrandgen.
o Removed 16-bit alignment restriction from kmrandgen.
o Improved WAV file extraction speed (Thanks to Jim Radford
for pointing this out).
o Added single-channel split for WAV extraction (asdcp-test -1).
o Fixed remainder bug in h__RNG::fill_rand().
2006.11.03 - Bug fixes v1.1.11
o Increased index table entry list size to 5000.
o Added length checking to TLV writer (returns error if TLV
payload exceeds 64kB).
o Fixed partition header and RIP errors related to 2-partition
files (MXF Interop mode).
o Added -t option to asdcp-test (SHA-1 digest with Base64 output
on stdout).
o Fixed Sub Descriptor reference bug (Thanks to Denis Leconte
for dogged determination).
o Added directory-of-wav detection to RawEssenceType()
o Modified MXF::Partition::AddChildObject() to only generate
a UUID if the InstanceID is unset.
o Added ComponentMaxRef & ComponentMinRef to RGBAEssenceDescriptor.
More to follow.
o Added detection of 2K/4K jp2c, writing correct 4K metadata.
2006.10.05 - Bug fixes v1.1.10
o Changed RM_RELEASE to RL_RELEASE in MXFTypes.h.
o Changed the MXF writer to use RL_RELEASE (was RL_DEVELOPMENT).
o Really fixed source reference chain.
o Updated JP2K file package label.
o Changed location of JPEG2000PictureSubDescriptor in the
header (was erroneously before Preface).
o Altered LS_MXF_INTEROP to produce 2-partition files.
2006.09.25 - Bug fixes v1.1.9
o Fixed SourcePackageID value. All files will be 'original',
i.e. SourcePackageID will be all zeros. Let me know if you
want to set SourcePackageID.
o Fixed compiler warnings on some Linux platforms
o Fixed the build so that BUILD_DIR is no longer created
as a dependency.
o Added duration detection to the raw essence parsers. The
MPEG parser uses a nasty approximation so don't use it
without paying close attention to the result.
o Modified PCMParserList to make it more useful as a base
class.
o Fixed bugs and re-organized command-line help in asdcp-test
and klvwalk.
o Fixed two-partition file reads.
o Fixed Win32 PRNG initialization.
o Renamed asdcp-lf-test as kmfilegen.
o Added kmrandgen and kmuuidgen.
o Added string retrieval mechanism to Result_t.
o Refactored Kumu::Identifier and its sub-classes.
o Altered Kumu::PathIsFile to return true when the path
is a symbolic link (unix only).
o Altered Kumu::FileWriter::OpenWrite to use file creation
mode 0664 (was 0644) (unix only).
o Added Kumu::WriteStringIntoFile() subroutine.
2006.04.05 - Bug fixes and new stuff v1.1.7
o Fixed a bug in the MPEG parser that caused it to fail when
handling start codes spanning buffer boundaries
o Added wavesplit and blackwave utility programs
o Added support for revised SMPTE HMAC key derivation when
using LS_MXF_SMPTE
o Refactored platform compatibility and general utilities
into a new sub-library "Kumu". There are no new build
steps or dependencies, but some important things have
changed:
+ Result_t is no longer an enum, it is now a class.
Library result codes are now declared as const objects
like this:
const Kumu::Result_t RESULT_FORMAT (-101, "The file...");
The macros ASDCP_SUCCESS and ASDCP_FAILURE still work
the same way thanks to an operator overload for type long.
See KM_error.h for more information.
+ The logging interface has been moved out of AS_DCP.h
and into KM_log.h
o Some of the command line utilities that were using headers
other than AS_DCP.h have been changed to use the Kumu
equivalents. If you have code based on those utilities, you
will have to update by hand.
o Added new types to the EssenceType_t enum.
o The guard macro for Win32 code has changed from WIN32 to
KM_WIN32.
2006.03.2x - new stuff
o Proper handling of stream-id byte of essence UL values
o writes 3-partition files, reads 2-part or 3-part
2006.03.16 - bug fixes plus
o Removed SMPTE_LABELS compile-time option. The reader will now
silently accept either SMPTE or MXF Interop labels, the writer
can be instructed which to use at runtime. Default is Interop.
o Added an AIFF reader. Support is preliminary, it works with the
AIFF files I have on hand.
o More code refactoring. More to come.
2006.03.09 - full read-write
o Removed ASDCP_WITHOUT_OPENSSL compile-time option.
o Full read/write now working on new MXF library
2005.00.00 - A New Hope
o The temporary mxf-lite has been removed. MXF files are now
managed via the objects in KLV.h, MXFTypes.h MXF.h and
Metadata.h. This release does not support writing MXF files.
o Fixed a header interpretation error in the Wav parser.
2005.00.00 - The Reformation
o Removed mxflib as a dependency by forking the necessary
functions and placing them in the mxf-lite subdirectory.
Please note that the very heavy modifications done here
render all comparisson to mxflib code a substantial task.
All errors are now mine and users are warned not to bug
Oliver or Matt for help with this code. The version of
mxflib at the time of the fork was: 0.5.1.3.
2005.06.03 - bug fixes v0.10.18
o Updated UL batch to include GC UL.
2005.05.27 - bug fixes v0.10.17
o Un-did essence container and compression descriptor changes.
The default build reflects MXF Interop decisions as of 26 May.
o Added note about build versions to README (see above).
o Added warnings to SMPTE_LABELS builds.
o Fixed JP2K essence container label.
2005.05.02 - bug fixes v0.10.16
o Reorganized internal files, added file reader object, added OS
portability header, removed and renamed some files. If you have a
patch against previous versions of the source, you should check
it thoroughly.
o Added RGBA attributes to JP2K descriptor.
o Changed interface to CodestreamParser.
o Added JP2K parser implementation. It is parsing each frame but is
not yet being used to populate the descriptor.
o Added 48fps option for `asdcp-test -p`.
o Added picture rate constants to AS_DCP.h (23.976, 24, 48).
o Added sample rate constant to AS_DCP.h (48k).
o Changed asdcp-test to encrypt picture headers by default
(plaintext offset will be 0), added -E option to allow
plaintext headers.
2005.04.28 - bug fixes v0.9.15
o The XML descriptors for the crypto DMS have moved in mxflib to
the file DMS_Crypto.xml (they were in DMS_DCPENC.xml). Older
installations should update the file from mxflib.
o Added Close() and Seek() to ~MyFileWriter(), cleaned up headers
o Added UUID generator output mode (-u).
o Added -S option to extract PCM essence into stereo wav files
o Added more UL testing and conformance checking.
o Added macro SMPTE_LABELS which causes the library to be built
with SMPTE (as opposed to MXF Interop) labels. This is not
set by default, and currently only affects the PCM container
label and encrypted element label.
o Cleaned up the GNUmakefile test targets, the source files
are now named with the TEST_FILE_PREFIX macro.
o enabled 23.976-framed PCM (2002 samples per frame)
o The size of the asdcp-test frame buffer for picture essence
may now be set from the command line (-b). The default is 4MB.
o h__Reader::ReadEKLVPacket() now tests the UL (duh) and switches
on the value, allowing plaintext and ciphertext frames to
be mixed in the file.
o Fixed error in UUID generator format.
o JP2K files now use the GenericPictureDescriptor to store
ContainerDuration and SampleRate. SampleRate is mapped
to EditRate in the PictureDescriptor struct. This fixes
the second caveat from the 0.8.13 release.
o Fxed bug in PCMParserList that was miscalculating the extent
of a PCM sample. This bug did not affect API users, it was
only present in asdcp-test.
o Fixed EditRate on PCM files (was showing sample rate)
o Fixed Encrypted Essence Container UL
o Fixed BlockAlign value for PCM essence
- The following changes were provided by Jeff Loewenguth
- Thanks Jeff!
o Moved the DMS CryptographicFramework entry from the material
package to the source package
o Fixed erroneous Source Essence Container Label value
o Fixed broken sort of JP2K frames in JP2K parser
o Added FindFrameGOPStart() method to the MPEG2 MXFReader
o Added missing length values for EKLV packets without HMAC
o -x with JP2K essence writes to files with 6 digit names
(up from 5 digits).
o The Key ID may now be specified as an argument to asdcp-test
(-j <key-id-string>)
2004.12.30 - bug fixes + wav files v0.8.14
o Added WAV file write to asdcp-test (uses mxflib::waveheader_t).
o Three-partition files reading properly. adscplib still writes
two-partition files.
o Changes in the mxflib WAV essence parser API had broken
asdcplib's ability to read essence from a WAV file. I have
fixed this bug, but at the expense of breaking compatibility
with older versions of mxflib. Beware!
o Removed redundant (but working) bin-text-bin conversions.
2004.12.23 - JPEG 2000 support v0.8.13
o Reads/writes JPEG 2000 essence in plaintext and ciphertext
with the following caveats:
