Justin Ruggles	1ac7d1ac50	ac3dec: fix coupling range check. the start subband must be less than the end subband. Originally committed as revision 18857 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Siarhei Siamashka	7d485f165f	Support for getting (i)MDCT output multiplied by a constant scaling factor. 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	16 years ago
Justin Ruggles	778bc09bbe	cosmetics: line wrap and vertical alignment Originally committed as revision 18752 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Justin Ruggles	396b73c7f7	ac3dec: Remove unneeded context variable, num_cpl_subbands. It is also 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	16 years ago
Justin Ruggles	52dc3fc83d	cosmetics: indentation after last commit Originally committed as revision 18750 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago

Justin Ruggles	95f3019a51	ac3dec: reorder output channels to SMPTE channel order Originally committed as revision 18542 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Thilo Borgmann	7a00bbad21	Implement avcodec_decode_video2(), _audio3() and _subtitle2() which takes an 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.
