Vitor Sessak	525ac37fd2	Optimize 1D DCT transform used in MP{1,2,3}. Makes also this function suitable for being moved to the shared DCT framework in the future. Originally committed as revision 23514 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	40914d97cc	1.0 and the resulting exactly representable value must be marked as float as well, gcc is hopelessly trash. Originally committed as revision 23119 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	0628f3e8cf	Cast constants to float to avoid gcc converting to and from float<->double in every operation. Originally committed as revision 23118 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	bfbdc58e52	Fix compilation with low precission mpeg audio decoding. Originally committed as revision 23107 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	3b7117b73a	Do the same sign flip optimization to the low freq decoder. as with the high freq 10-20 cycles faster Originally committed as revision 23099 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	4b070a7a61	Factorize READ_FLIP_SIGN() optimization out Originally committed as revision 23098 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	0c0d88aed5	Optimize decoding high freqs. this is 10-20cpu cycles faster on duron (whole is about 50-60 cpu cylses) I wonder why gcc isnt doing this on its own ... Originally committed as revision 23097 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	fd9451c68f	Make lsf_sf_expand() 4 times faster. Originally committed as revision 23096 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago

Diego Biurrun	ba87f0801d	Remove explicit filename from Doxygen @file commands. Passing an explicit filename to this command is only necessary if the documentation in the @file block refers to a file different from the one the block resides in. Originally committed as revision 22921 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Stefano Sabatini	72415b2adb	Define AVMediaType enum, and use it instead of enum CodecType, which is deprecated and will be dropped at the next major bump. Originally committed as revision 22735 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Måns Rullgård	da0ac0ee64	Make some functions static These functions are not used outside their respective files, and they lack a prototype in a header. Originally committed as revision 22259 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Måns Rullgård	84dc2d8afa	Remove DECLARE_ALIGNED_{8,16} macros These macros are redundant. All uses are replaced with the generic DECLARE_ALIGNED macro instead. Originally committed as revision 22233 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Måns Rullgård	c67278098d	Move array specifiers outside DECLARE_ALIGNED() invocations Originally committed as revision 21377 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Ronald S. Bultje	6e44ba1550	Use get_bits_left() instead of size_in_bits - get_bits_count(). Originally committed as revision 20543 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Vitor Sessak	c902340599	Reduce stack memory allocation in MP3 decoder Originally committed as revision 20451 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Reimar Döffinger	eadaa00c6f	Add support for hardcoding the mpegaudiodec tables. Reduces .bss size by about 194 kB. Originally committed as revision 20400 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Reimar Döffinger	9adcccde0c	mpegaudiodec, mpc and qdm2 all use the same mpa_synth window, so make them use the same variable/global storage. Saves 4 kB in .bss. Originally committed as revision 20314 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Reimar Döffinger	a57afd2943	Partially revert r20233, exp2f is not available on some BSDs, DOS and AVR32. Originally committed as revision 20240 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Reimar Döffinger	686884da9d	Use cbrtf and exp2f instead of pow to calculate tables for MPEG audio decoding. This hopefully is fast enough so that it is reasonable to use the same formula directly instead of the table for CONFIG_SMALL. Originally committed as revision 20233 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	45a014d75e	Set data_size to 0 to avoid having it uninitialized. based on 31_mp3_outlen.patch by chrome. Originally committed as revision 19988 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago

Michael Niedermayer	0d31833d04	check data_size in decode_frame() Originally committed as revision 19986 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Diego Biurrun	83614f2df9	Reduce pointless verbosity after seeks in the MP3 decoder. Originally committed as revision 19759 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Michael Niedermayer	822d0a6e0c	Drop code that attempts to decode frames that are prefixed by junk. Too often it ends up decoding random data into noise without detecting it (for example after seeking of some MP3 data with oddly often occurring startcode emulation). Fixes issue1154. Originally committed as revision 19302 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Måns Rullgård	1e24f1b25d	mpegaudio: enclose SUM8() macro args in parens when used Originally committed as revision 18746 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago

Zdenek Kabelac	e2fa5cf4c9	Do not scan for MP3 header after the given buffer and return skipped bytes along with consumed bytes on successful decoding. patch by Zdenek Kabelac, zdenek.kabelac gmail com Originally committed as revision 18736 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Michael Niedermayer	b52b6ae489	Remove unused variable from decode_init() found by CSA. Originally committed as revision 18550 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

Diego Biurrun	bad5537e2c	Use full internal pathname in doxygen @file directives. Otherwise doxygen complains about ambiguous filenames when files exist under the same name in different subdirectories. Originally committed as revision 16912 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Andreas Öman	cf92cec7d8	Avoid allocating MPADecodeContext on stack. Instead move relevant fields into MPADecodeHeader and use it where appropriate. Originally committed as revision 16728 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago

Diego Biurrun	0f6a659ddf	Replace #ifdef CONFIG_ preprocessor check by #if CONFIG_. CONFIG_ changed semantics and is always defined now. Originally committed as revision 16598 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Diego Biurrun	ad1eebe360	Use CONFIG_MPEGAUDIO_HP directly instead of USE_HIGHPRECISION indirection. Originally committed as revision 16594 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Aurelien Jacobs	b250f9c66d	Change semantic of CONFIG_, HAVE_ and ARCH_*. They are now always defined to either 0 or 1. Originally committed as revision 16590 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Michael Niedermayer	cb595b7f02	Add dummy mp1_decoder to complement the existing dummy mp2/mp3 decoders. Originally committed as revision 16581 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Andreas Öman	11c23b64ac	Revert r16257: Include "libavutil/common.h" where we use llrint() in case ffmpeg's own llrint() is to be used. Originally committed as revision 16282 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Andreas Öman	1af34f094e	Include "libavutil/common.h" where we use llrint() in case ffmpeg's own llrint() is to be used. Originally committed as revision 16257 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Måns Rullgård	4deaa94639	Add shift argument to MULL() macro This replaces use of FRAC_BITS in the MULL() definition with a third argument specifying the shift amount. All uses of this macro are updated to pass FRAC_BITS as third argument. Originally committed as revision 15921 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Aurelien Jacobs	37d3e0667a	uses FF_ARRAY_ELEMS() where appropriate Originally committed as revision 15662 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
