AS_DCP.h contains the entire API. You do not need to read

To build, type 'make'. There are several test targets but you
need to assemble a set of test files to use them.
Change History
-2007.06.xx - Timed Text and Bug fixes v.1.1.15
- o Added support for draft SMPTE 429-5 Timed Text Track File. See
- AS_DCP_TimedText.h for the API. This is *very* experimental, so
- do not use for shipping products. Timed Text support is NOT part
- of the default build, run `make WITH_TIMED_TEXT=1` to enable
- this part of the library. AS_DCP_TimedText.h will be combined
- with AS_DCP.h when it becomes stable. Because we need an XML
- parser to create the Track File, expat is now part of the Timed
- Text build. Follow the XML_PARSER macro in the makefile and KM_xml
- to see how you can support your favorite parser. See also
- S429-5-cgi.cpp for an example that shows how to serve plaintext
- MXF file elements directly via HTTP.
+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
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 this work does not affect existing stable file support,

users are cautioned to test this release thouroughly.
- o Added a large set of path manglers to KM_fileio.h. See
+ 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

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().
