2015-02-19 – PHDR feature, bug fixes, 2.4.9

• 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.
• 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.)
• 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.
• 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).
• 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.)
• Fixed ST 429-5 / ST 2067-5 wrapping to increase header space when ancillary resources are present (fixes a bug that caused the header to overflow the allotted space when large numbers of PNG files were present.)
• Refactored GetXMLDocType() to use the XML parser.
• Added ParseFirstFromString() method to Kumu::XMLElement
• Removed Kumu::StringIsXML from the API.
• Added ASDCP::MXF::RGBALayout type.
• Added J2CLayout property to JPEG2000PictureSubDescriptor
• Changed km_token_split() to retain empty elements in the output list.
• Added PHDR wrapping for AS-02.
• 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.

• Exposed MXF object interface (MXF.h, Metadata.h) via ASDCP MXFReader and MXFWriter classes.
• 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!
• Added MCALabelSubDescriptor, AudioChannelLabelSubDescriptor, SoundfieldGroupLabelSubDescriptor, and GroupOfSoundfieldGroupsLabelSubDescriptor (from ST 377-4:2012) to Metadata.h
• Changed some internals to make MXFWriter::OPAtomHeader() work correctly.
• 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.
• 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).

change log:
2007.10.22 – Timed Text, Stereoscopic Picture and Bug fixes v.1.2.16

• 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.
• Fixed RFC 2104 HMAC implementation for LS_MXF_SMPTE only. The broken implementation has been maintained for Interop mode.
• 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.
• 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.
• Refactored the following files as a side-effect of the above work: AS_DCP_JP2K.cpp AS_DCP_MPEG2.cpp AS_DCP_PCM.cpp AS_DCP_MXF.cpp AS_DCP_internal.h MXF.[h|cpp] MXFTypes.[h|cpp] Metadata.[h|cpp] h__Reader.cpp h__Writer.cpp klvwalk.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.
• 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.
• The PathIsFile(), PathIsDirectory() and FileSize() subroutines have been modified to accept const std::string& instead of const char*.
• Added namespace and parsing support (Expat) to Kumu::XMLElement (currently used only for Timed Text support). Also added some new accessors.
• Altered MXF::UTF16String to use mbtowc() and wctomb().

change log:
2007.03.31 – Bug fixes v.1.1.14

• 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 **
• Fixed error in RIP interpretation when reading arbitrary (i.e., non-MXF) files.
• 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.
• Removed asserts from KM_fileio, replaced with RESULT_WRITEFAIL return value statements.
• Added -s and -p to the makefile install target.
• Altered ByteString behavior to use target Length() in copy operations (instead of Capacity()).
• Added new Set() method to ByteString.
• 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).
• Added IdentifierList class to KM_util.
• Changed some Error() messages to Debug() in Wav.cpp
• Revived jp2k-test.cpp and asdcp-mem-test.cpp (they both had stale #includes).

2007.02.15 – Bug fixes v1.1.13

• Removed ‘VDescObj->SampleRate.Numerator = VDesc.FrameRate;’ from MPEG2_VDesc_to_MD() in AS_DCP_MPEG2.cpp, was line 76.
• 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.
• MPEG2 VES with run of zero values at the head is now OK.
• Increased VESHeaderBufSize to 16K.
• Added makefile support for local OpenSSL in ../openssl, if present.
• The Kumu::PathIs*() functions now return false if a null or empty string is given (used to be an assert).
• Cleaned up the install target in the makefile.
• Fixed SMPTE 429-6 HMAC — FIPS 186-2 implementation was laughably incorrect. Thanks to Doremi for pointing this out.
• Removed default parameter to HMACContext::InitKey().
• Cleaned up messages and CLI arg handling in asdcp-test.

• Changed read-only Result_t accessor methods to const.
• Added Base64 (-B) option to kmrandgen.
• Removed 16-bit alignment restriction from kmrandgen.
• Improved WAV file extraction speed (Thanks to Jim Radford for pointing this out).
• Added single-channel split for WAV extraction (asdcp-test -1).

• Increased index table entry list size to 5000.
• Added length checking to TLV writer (returns error if TLV payload exceeds 64kB).
• Fixed partition header and RIP errors related to 2-partition files (MXF Interop mode).
• Added -t option to asdcp-test (SHA-1 digest with Base64 output on stdout).
• Fixed Sub Descriptor reference bug (Thanks to Denis Leconte for dogged determination).
• Added directory-of-wav detection to RawEssenceType()
• Modified MXF::Partition::AddChildObject() to only generate a UUID if the InstanceID is unset.
• Added ComponentMaxRef & ComponentMinRef to RGBAEssenceDescriptor. More to follow.
• Added detection of 2K/4K jp2c, writing correct 4K metadata.

2006.09.25 – Bug fixes v1.1.9

• Fixed SourcePackageID value. All files will be ‘original’, i.e. SourcePackageID will be all zeros. Let me know if you want to set SourcePackageID.
• Fixed compiler warnings on some Linux platforms
• Fixed the build so that BUILD_DIR is no longer created as a dependency.
• 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.
• Modified PCMParserList to make it more useful as a base class.
• Fixed bugs and re-organized command-line help in asdcp-test and klvwalk.
• Fixed two-partition file reads.
• Fixed Win32 PRNG initialization.
• Renamed asdcp-lf-test as kmfilegen.
• Added kmrandgen and kmuuidgen.
• Added string retrieval mechanism to Result_t.
• Refactored Kumu::Identifier and its sub-classes. is a symbolic link (unix only).

change log:
2013-07-02 – IMF/AS-02 support, bug fixes 2.0.0

• 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.
• Final integration of Fraunhoffer IIS code contribution.  AS-02
  files are now fully supported with some TODOs and one major
  exception: LEAD indexes are not supported by the MXF writers
  and interlace images are not yet supported.
• 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
  understand this feature.
