that allows making a descriptor copy that is not owned by
any other strucure. The caller must arrange to delete the
object pointer returned.
o While implementing the above it became obvious that the
reference-to-a-pointer-to-the-dictionary idiom that is used
throughout the lower levels of the MXF library was the
cause of much more grief than it was originally designed to
prevent. This was made even more obvious when I replaced all
of it with simple pointers, which revealed several shadow
instances of m_Dict that were only reliable while the object
that held them was valid.

We ran American Fuzzy Lop on IMF IAB master file reader and discovered a lot of crashes. These are fixes in the asdcplib code base.

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
o 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 tarck clip was instead being
o written as a DM track
o Fixed UL values DCDataDescriptor and ContainerConstraintSubDescriptor to have
o a byte 6 value of 0x53 (Tag Set) instead of 0x07 (coding sentinel)
o Added UL values 492 - 511 to the dictionary
o Added ApplicationSchemes and ConformsToSpecifications to the Preface set
o Added default initializer to MXF::LineMapPair
o Added sets DescriptiveFramework, DescriptiveObject, TextBasedDMFramework,
o TextBasedObject, GenericStreamTextBasedSet and ISXDDataEssenceDescriptor
o Added ISXD support and options '-G', '-u' to as-02-wrap
o Added ISXD support and option '-g' to as-02-unwrap

global metadata

o Fixed a bug that caused incorrect failure when parsing JPEG 2000 codestreams having fewer than five decomposition levels.
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

changes were made to satisfy the new compiler:
- Altered many printf format codes to use the correct type for the given integer type
- Parenthesized some expressions to clarify previously ambiguous expectations of 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()
o Added platform-independent call Kumu::GetExecutablePath() (test with win32)
o Fixed a bug that was causing Array properties to be written without the (count, length) header (from PAL)
o Fixed Win32 build (from Crowe)
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 Improved integration of ST 377-4 MCA concepts with ST 429-2 static
labels.
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.

work will require changes in SMPTE ST 429-5 and perhaps other
standards work, so files created with this implementation are
"speculative". Publication of the revised ST 429-5 may not occur
until early 2015.
o Moved LocalFilenameResolver into the AS_DCP public API so that it
can be used by other modules including AS-02.
o Fixed wave wrapping UL in clip-wrapped AS-02 files. Renamed some
UL constants to reflect "clip" or "frame" wrapping.
o Re-factored JP2K_PDesc_to_MD() and MD_to_JP2K_PDesc() to work
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 Fixed the version byte on the following UL values:
StereoscopicPictureSubDescriptor
GenericPictureEssenceDescriptor_ColorPrimaries
GenericPictureEssenceDescriptor_ActiveHeight
GenericPictureEssenceDescriptor_ActiveWidth
GenericPictureEssenceDescriptor_ActiveXOffset
GenericPictureEssenceDescriptor_ActiveYOffset
o Added some essence descriptor options to as-02-wrap.
o Added TTML timed-text wrapping option to as-02-wrap.
o Changed bit rate display in asdcp-info from mebi-bits/s to
mega-bits/s.
o Added "SMPTE" / "Interop" format type display to asdcp-info.
o Modified asdcp-wrap to assume -L when wrapping timed-text (since
there is no MXF text wrapping for Interop.)
o Fixed missing-index-partion bugs for AS-02 files.
