2011-01-28Add ff_ prefix to data symbols of encoders, decoders, hwaccel, parsers, bsf.Diego Elio Pettenò
None of these symbols should be accessed directly, so declare them as hidden. Signed-off-by: Mans Rullgard <mans@mansr.com> (cherry picked from commit d36beb3f6902b1217beda576aa18abf7eb72b03c)

Originally committed as revision 23784 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-04-20Remove explicit filename from Doxygen @file commands.Diego Biurrun
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

is deprecated and will be dropped at the next major bump. Originally committed as revision 22735 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-01-14Implement alpha channel decoding for BGR HuffYUV.Alexander Strange

2009-09-06Mark all pix_fmts and supported_framerates compound literals as const.Reimar Döffinger

Fixes issue1237. Originally committed as revision 19322 to svn://svn.ffmpeg.org/ffmpeg/trunk
2009-05-23Fix passing of unaligned addresses to dsputil diff_bytes() byJeff Downs
changeing calls to sub_left_prediction such that the source frame data pointers are no longer offset to skip the initial elements. This keeps them properly aligned for the subsequent call to diff_bytes. Changes encoding offset to compensate. Mailing list thread: https://lists.mplayerhq.hu/pipermail/ffmpeg-devel/2009-May/069952.html Originally committed as revision 18919 to svn://svn.ffmpeg.org/ffmpeg/trunk
2009-05-23Add offset argument to encode_422_bitstream() to control whereJeff Downs
in the source data array to start encoding. Change all calls to pass zero for this new argument for equivalent behavior. This is a restructure to support a forthcoming bug fix. Originally committed as revision 18918 to svn://svn.ffmpeg.org/ffmpeg/trunk
2009-04-13Rename bitstream.h to get_bits.h.Stefano Sabatini
Originally committed as revision 18494 to svn://svn.ffmpeg.org/ffmpeg/trunk

thus avoiding potential memleaks and pointless memcpys. Originally committed as revision 18470 to svn://svn.ffmpeg.org/ffmpeg/trunk
2009-04-12Split bitstream.h, put the bitstream writer stuff in the new fileStefano Sabatini
put_bits.h. Originally committed as revision 18461 to svn://svn.ffmpeg.org/ffmpeg/trunk
2009-04-07Implement avcodec_decode_video2(), _audio3() and _subtitle2() which takes anThilo Borgmann
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.

Originally committed as revision 16082 to svn://svn.ffmpeg.org/ffmpeg/trunk
2008-09-08Bump Major version, this commit is almost just renaming bits_per_sample toLuca Abeni
bits_per_coded_sample but that cannot be done seperately. Patch by Luca Abeni Also reset the minor version and fix the forgotton change to libfaad.
