| | | | | | about 1.8% faster on my system. Originally committed as revision 20090 to svn://svn.ffmpeg.org/ffmpeg/trunk

* ac3dec: simplify zero-bit mantissa dithering by calculating itJustin Ruggles2009-08-05
| | | | | | | conditionally during mantissa decoding, then only removing it from the coupling range for coupled channels which do not use dithering. Originally committed as revision 19588 to svn://svn.ffmpeg.org/ffmpeg/trunk

* Modify decode_band_structure() so that the actual band structure is onlyJustin Ruggles2009-08-05
| | | | | | | used within the function. This removes the need to have the coupling band structure stored in the AC3DecodeContext. Originally committed as revision 19585 to svn://svn.ffmpeg.org/ffmpeg/trunk

* eac3dec: revert commit r18860. keep the AHT IDCT 24-bit. will make AHT GAQJustin Ruggles2009-05-21
| | | | | | dequantization 24-bit in a separate commit. Originally committed as revision 18887 to svn://svn.ffmpeg.org/ffmpeg/trunk

* eac3dec: use 16-bit pre-mantissas instead of 24-bit in AHT decoding. it isJustin Ruggles2009-05-17
| | | | | | simpler and also fixes a bug in GAQ dequantization. Originally committed as revision 18860 to svn://svn.ffmpeg.org/ffmpeg/trunk

| | | | | | | | Scaling (i)MDCT output has no runtime overhead and can be used to improve performance of audio codecs. All the changes are only needed in 'ff_mdct_init' function and slow down initialization a bit. Originally committed as revision 18855 to svn://svn.ffmpeg.org/ffmpeg/trunk

| | | | Originally committed as revision 18752 to svn://svn.ffmpeg.org/ffmpeg/trunk
* ac3dec: Remove unneeded context variable, num_cpl_subbands. It is alsoJustin Ruggles2009-05-06
| | | | | | | | not needed for spectral extension or enhanced coupling since it is redundant information, so I am removing it from decode_band_structure() as well. Originally committed as revision 18751 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.
