* 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>

* Define AVMediaType enum, and use it instead of enum CodecType, whichStefano Sabatini2010-03-30
| | | | | | is deprecated and will be dropped at the next major bump. Originally committed as revision 22735 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Rename bitstream.h to get_bits.h.Stefano Sabatini2009-04-13
| | | | Originally committed as revision 18494 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Implement avcodec_decode_video2(), _audio3() and _subtitle2() which takes anThilo Borgmann2009-04-07
| | | | | | | | | | | 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.

* Merge the 2 lpc loops.Michael Niedermayer2008-09-23
| | | | | | | | This changes the output by (stddev: 0.21 PSNR:109.51, file:ddinterview28.ra), the changes are due to float rounding inaccuracies and do not happen if doubles are used. Originally committed as revision 15394 to svn://svn.ffmpeg.org/ffmpeg/trunk

* Use SAMPLE_FMT_FLT instead of doing the float->int conversion in theVitor Sessak2008-09-17
| | | | | | | decoder. This changes the output very little and any difference should be inaudible. Originally committed as revision 15343 to svn://svn.ffmpeg.org/ffmpeg/trunk

* Flip (by making buf[i] -> buf[size-i-1]) two buffers: {sp,gain}_block. ThisVitor Sessak2008-08-06

* Cosmetics: remove braces and useless newlineVitor Sessak2008-07-28

* Change the way the input is passed to do_hybrid_filter(). Before, in[0] wasVitor Sessak2008-07-28
| | | | | | | the oldest input sample passed and in[n-1] was the latest. Now it is the contrary. This allows making backward_filter() somewhat simpler. Originally committed as revision 14447 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Remove RA288Context.output buffer. This buffer is just RA288Context.sbVitor Sessak2008-07-28
| | | | | | | | backwards (output[i] == sb[N-i], where N is the buffer length). This makes the code slower, this will be fixed in my next commit. Originally committed as revision 14446 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Add a few comments pointing to the G.728 specificationVitor Sessak2008-07-27
| | | | Originally committed as revision 14444 to svn://svn.ffmpeg.org/ffmpeg/trunk

| | | | | | comments. Originally committed as revision 14437 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Remove st1 and st2 temporary buffers in backward_filter() and use insteadVitor Sessak2008-07-27
| | | | | | | | RA288Context.pr{1,2}. Note that the pr{1,2} buffers are one unity smaller than the st{1,2} buffers. My guess is that the original coder decided to add one to the array sizes "just to be sure". Originally committed as revision 14435 to svn://svn.ffmpeg.org/ffmpeg/trunk
