This is the inaugural release of MP4v2. + +This project's goal is to continue development of a C-library named +`libmp4v2' which was once a part of the (now defunct) MPEG4IP project. +That library, and some related command-line utilities were branched +from MPEG4IP version 1.6.1 to seed this project, MP4v2. + +2 Breaking Changes +****************** + +2.1 Top-level header file +========================= + +This release is nearly 100% API compatible with MPEG4IP, however there +are some differences. Dependents of this library must now include the +top-level public header file as follows. This is the only supported +mechanism to include the library. We do not support attempts to include +any sub-level header files; such files are private implementation +details and their naming must not be relied upon. + + #include <mp4v2/mp4v2.h> + +2.2 Command-line utilities +========================== + +The command-line utilities have been totally rewritten and enhanced. +Help usage has been made more consistent and enhanced, please invoke +the appropriate utility in this fashion for more details: + + command --help + +Appendix A Changelog +******************** + +A.1 Version 1.9 +=============== + + 1. Renamed public API top-level header to `<mp4v2/mp4v2.h>' and added + namespaces for implementation (private) symbols. Only public API + symbols are exported for dynamic (shared) or DLL libraries. All + other symbols are now private, notwithstanding static-library + usage. + + 2. Added initial AC3 support. + + 3. Added native Windows port. The port targets `WINVER 0x0500' which + is Windows 2000 or higher. + + 4. Added QuickTime and Nero chapter support. See `mp4chaps' + command-line utility. + Contributed by Ullrich Pollähne <u.pollaehne@gmail.com>. + + 5. Enhanced `mp4art' to support multiple cover-art atoms. + + 6. Dropped `mp4dump' and replaced with `mp4file' which supports + general file operations. + + 7. Added `mp4track' with colr-box and pasp-box support. + + 8. Fixed corruption of udta.name atom during read-in. + + 9. Enhanced `mp4file --dump' to show hexdump-style canonical + hex+ASCII data. + + 10. Enhanced `mp4file --dump' to show human-readble value for tag + typeCode values. + + 11. Enhanced `mp4file --dump' to show human-readble value for + ISO-639-2/T language codes. + + 12. Added new public-API: MP4GetTrackLanguage(). + + 13. Added new public-API: MP4SetTrackLanguage(). + + 14. Added support for GCC precompiled-headers on various *nix + platforms to speed up builds as we are using quite a few C++ + headers. + + 15. Enhanced `mp4track' to facilitate modification of { enabled, + inmovie, inpreview, altgroup, volume, width, height, language, + hdlrname, udtaname } properties. + + 16. Added new public-API: MP4GetTrackDurationPerChunk(). + + 17. Added new public-API: MP4SetTrackDurationPerChunk() to override + default per-track chunk duration. + + 18. Added new public-API: MP4WriteSampleDependency(). + + 19. Replaced (undocumented) public-API: MP4CreateEx() with + MP4CreateProvider(). + + 20. Added new public-API for iTMF Generic functionality. + +A.2 Version 1.6 +=============== + + 1. Branched libmp4v2 module from mpeg4ip project version 1.6.1. + +Appendix B SCM repository details +********************************* + + url: https://mp4v2.googlecode.com/svn/releases/1.9.1 + root: https://mp4v2.googlecode.com/svn + uuid: 6e6572fa-98a6-11dd-ad9f-f77439c74b79 + rev: 368 + date: 2009-07-14 11:25:03 +1200 (Tue, 14 Jul 2009) + type: stable + |
