Måns Rullgård	dc0d86face	AAC: use table for cbrtf(n)*n The maximum length of escape_sequence is 21 bits, so adjust limit in code to match this. Up to 10% faster on Cortex-A8. Originally committed as revision 21153 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Måns Rullgård	7c8af53f87	AAC: escape_sequence is 21 bits max The maximum length of escape_sequence is 21 bits, so adjust limit in code to match this. Also fix the comment. Originally committed as revision 21151 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago

Carl Eugen Hoyos	257c7147e1	Use enum and constant to avoid three icc warnings. Originally committed as revision 20874 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Andreas Öman	f658631419	aac: Set sample rate in avctx from ADTS header (if not already set by some other means) Originally committed as revision 20773 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Alex Converse	4fab662769	AAC: Add a global header but output not locked output configuration status. Originally committed as revision 20701 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Alex Converse	38610d92ff	Set the SBR mode to implicit on ADTS frames occurring before the output is locked. Originally committed as revision 20700 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Alex Converse	4e878a1898	10l: Fix inverted if-condition from r20448. Fixes issue 1562. Originally committed as revision 20570 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Alex Converse	01d19fbc9f	AAC: Rename sect_len to sect_end. It marks the last sfb of the section, not the length of the section. Originally committed as revision 20513 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Alex Converse	981b8fd777	Don't lock the channel output configuration based on the first value seen for non extradata formats. Instead lock it only after the successful decoding of a frame. This fixes issue 999. Originally committed as revision 20448 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Robert Swain	0359289d1d	AAC: Fix regression introduced in r20067 where ADTS files would always be signalled as having a channel configuration of 1 in output_configure(). Previously this didn't matter but it does now. Originally committed as revision 20193 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
David Conrad	144fec83b3	dca and aac decoders use float_to_int16_interleave, so check for the C version of that rather than float_to_int16. Fixes output on ARM/VFP Originally committed as revision 20192 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Robert Swain	754ff9a795	Refactor channel element configuration and mapping code into its own function to allow reuse Originally committed as revision 20069 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Robert Swain	2309923c5c	Reindent after last commit Originally committed as revision 20068 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago

Alex Converse	5419da8d9c	AAC: Simplify some logic from r19956. (The escape codebook is unsigned.) Originally committed as revision 19958 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Måns Rullgård	42d3fbb3f4	AAC: use new dsputil functions Originally committed as revision 19956 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Reimar Döffinger	b5f09d31c2	Make sample_fmts and channel_layouts compound literals const to reduce size of .data section. Originally committed as revision 19787 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago

Alex Converse	36f517736f	Cosmetics: reindent after last commit Originally committed as revision 19400 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
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.

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

Alex Converse	03b127477f	Re-indent after last commit. Originally committed as revision 17211 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Alex Converse	f1ade11e33	Make set coup.gain[c][0] aand only coup.gain[c][0] is set for a independently switched CCE. Discussed/OKed at http://lists.mplayerhq.hu/pipermail/ffmpeg-devel/2009-February/062219.html Originally committed as revision 17210 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
