AS-DCP File Access Library

asdcplib is an open source implementation of SMPTE and the MXF Interop "Sound & Picture Track File" format. It was originally developed with support from DCI. Development is currently supported by CineCert and other D-Cinema manufacturers. See the bundled README file for more information. asdcplib is implemented in C++ and builds on Win32 and most unix platforms that support GCC.

The following SMPTE standards (and their normative references) are supported:

  • 377M-2004
  • 381M-2005
  • 382M-2007
  • 429-3-2006
  • 429-4-2006
  • 429-5-2008
  • 429-6-2006
  • 429-10-2008

asdcplib supports reading and writing MXF files containing sound (PCM), picture (JPEG 2000 or MPEG-2) and timed-text (XML) essence. Plaintext and ciphertext are both supported using OpenSSL for cryptographic support. An object-oriented API is provided along with a command-line program asdcp-test that provides access to most of the API.

change log:
2009.05.21 - bug fixes, v.1.4.24
  • 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.

change log:
2009.04.09 - SMPTE format fixes, enhancements and bug fixes, v.1.4.22

change log:
2008.02.16 - SMPTE format fixes, bug fixes v.1.3.18
  • Added correct SMPTE UL for StereoscopicPictureSubDescriptor.
  • Exposed JP2K metadata parser as ParseMetadataIntoDesc().
  • Added simple stereoscopic framebuffer to support paired ReadFrame() and WriteFrame() methods (allows simpler integration with other single-buffer code).
  • Improved detection of JPEG Interop stereoscopic files.
  • Win32 build fixes (Thanks to Mike Crowe at DTS).
  • Added the WITH_MD macro to the makefile. Set this value to one to build Win32 with /MD[d] instead of /MT[d].
  • 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.
  • Major refactoring of KM_log.[h|cpp].
  • Fixed buffer re-sizing issue in Kumu::ByteString.
  • Replaced type IdentifierList with ArchivableList.

Download version 1.2.17 (development version)
MD5 digest value: = c4e43437c8e56000d99fbb422c864262

change log:
2007.12.13 - Bug fixes v.1.2.17
  • Changed Result_t implementation to use int instead of long, which was causing trouble on some 64 bit platforms.
  • 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.
  • Fixed HMAC sequence numbering in encrypted stereoscopic files.
  • Finished stereoscopic test targets in the makefile.
  • Fixed the win32 build, now expects VS2005 compiler by default, use WITH_VC6=1 top get VC6 flags.
  • 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.
  • Changed a bunch of symbol names in the 429-5 implementation to better match the spec.
  • Added -U option to asdcp-test to dump the UL library to stdout.
  • Fixed erroneous placement of the PictureEssenceCoding UL in JP2K files (Interop and SMPTE modes).

Download version 1.2.16 (development version)
MD5 digest value: = 959d2fd5d1c31fcfd93a9003fc93231c

KNOWN BUGS: The following issues are known to exist with this version. These bugs will be fixed in the next release (being prepared now).

  • The Win32 build is broken
  • Writing encrypted track files using LS_MXF_SMPTE causes a segfault

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).

  • 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.

  • 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.
