Alex Converse	6308765cb5	Ignore subsequent channel configurations after the first in an AAC file. The current code doesn't handle them properly, and they are a dubious construction at best. Originally committed as revision 19399 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Ronald S. Bultje	ce863d7f36	Rename ff_log_missing_feature() to av_log_missing_feature(). Originally committed as revision 19294 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Alex Converse	d4eeef0c19	Cosmetics: Re-indent after last commit Originally committed as revision 19175 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Alex Converse	85e9296f41	Move TNS and swb_offset tables from aacdectab.h to aactab.c so that they can be shared with the AAC encoder. Originally committed as revision 19174 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Alex Converse	401a995085	In the event of a mismatch, do not follow the sample rate index in an AAC PCE. This matches the behavior the reference decoder and fixes issue 1072. Originally committed as revision 18957 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
Alex Converse	90350d73f8	Allow parsing and decoding of ADTS AAC files with channel config = 0 Originally committed as revision 18815 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Robert Swain	7bbd2fb126	Remove redundant assignment. err is assigned in every switch case anyway. Issue found by CSA. Originally committed as revision 18641 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Robert Swain	5967e1413e	Remove unnecessary assignment, found by CSA. Originally committed as revision 18617 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Stefano Sabatini	9106a698e7	Rename bitstream.h to get_bits.h. Originally committed as revision 18494 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. Originally committed as revision 18351 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago

Alex Converse	51741a82c3	If we get an error from ff_aac_parse_header() we should not trust the header info that it provides. Originally committed as revision 17860 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago

Robert Swain	341b28c0d2	Zero 'idx' for each iteration of the coupling gain loop and as it is only used within this loop, we can move its declaration there too.
