* lavc: use designated initialisers for all codecs.Anton Khirnov2011-07-29
| | | | It's more readable and less prone to breakage.
* doxygen: Consistently use '@' instead of '\' for Doxygen markup.Diego Biurrun2011-06-24
| | | | Signed-off-by: Diego Biurrun <diego@biurrun.de>
* Replace FFmpeg with Libav in licence headersMans Rullgard2011-03-19
| | | | Signed-off-by: Mans Rullgard <mans@mansr.com>
* Add ff_ prefix to data symbols of encoders, decoders, hwaccel, parsers, bsf.Diego Elio Pettenò2011-01-26
| | | | | | | None of these symbols should be accessed directly, so declare them as hidden. Signed-off-by: Mans Rullgard <mans@mansr.com>
* Move #ifdef before zlib_decomp() up so it covers the Doxygen comments.Diego Biurrun2010-07-02
| | | | | | Otherwise Doxygen gets confused and cannot map comments to functions. Originally committed as revision 23988 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Remove explicit filename from Doxygen @file commands.Diego Biurrun2010-04-20
| | | | | | | | Passing an explicit filename to this command is only necessary if the documentation in the @file block refers to a file different from the one the block resides in. Originally committed as revision 22921 to svn://svn.ffmpeg.org/ffmpeg/trunk

| | | | Originally committed as revision 19057 to svn://svn.ffmpeg.org/ffmpeg/trunk
* 100l, the compression field in lcl extradata must be interpreted asReimar Döffinger2009-05-31
| | | | | | | int8_t, not uint8_t to allow -1 for "no compression". The original code worked, but only when char was signed. Originally committed as revision 19056 to svn://svn.ffmpeg.org/ffmpeg/trunk

| | | | | | | | | | | AVPacket argument rather than a const uint8_t *buf + int buf_size. This allows passing of packet-specific flags from demuxer to decoder, such as the keyframe flag, which appears necessary to playback corePNG P-frames. Patch by Thilo Borgmann thilo.borgmann googlemail com, see also the thread "Google Summer of Code participation" on the mailinglist.
