Mans Rullgard	6bb6fb05ba	mpegaudio: remove CONFIG_MPEGAUDIO_HP option The low quality mode is off by default and never tested. The high quality mode is also plenty fast enough. Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago

Diego Elio Pettenò	d36beb3f69	Add ff_ prefix to data symbols of encoders, decoders, hwaccel, parsers, bsf. None of these symbols should be accessed directly, so declare them as hidden. Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago

Clément Bœsch	c19a216af3	Handle ID3v1 tag while decoding mp[123] frames patch by Clément Bœsch (ubitux at gmail) Originally committed as revision 26297 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Alexander Kojevnikov	49d7ef282d	Show correct bitrate for VBR MP3 files. Patch by Alexander Kojevnikov, alexander kojevnikov com Originally committed as revision 24539 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	69b56ed7a6	Move ff_dct_init(context) out of if(one time init) fixes calling a null pointer in issue658 Originally committed as revision 24081 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Måns Rullgård	59bebb11e0	mpegaudio: move compute_antialias_float() to mpegaudiodec_float.c Also put compute_antialias_integer() under !CONFIG_FLOAT and change forward declarations to declare only the relevant one of these. Fixes warnings about unused functions and pointer type mismatches. Originally committed as revision 23950 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Måns Rullgård	35d597d556	mpegaudio: call ff_mpegaudiodec_init_mmx() only from float decoder The mmx code is floating-point only, and this function does not know from which decoder it is called. Without this change, the integer decoder only "works" because the size of the context struct is smaller in this case, and the mmx init function writes the function pointer outside the allocated context. Fixes issue 2054. Originally committed as revision 23949 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Aurelien Jacobs	956dae9e77	adu and mp3on4 functions are also needed by their respective float decoders Originally committed as revision 23944 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago

Vitor Sessak	4d49a5a785	Factorize the mpegaudio windowing code in a function and call it by a function pointer. Should allow for ASM optimizations. Originally committed as revision 23646 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
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	f7304e99d4	Check data_size in decode_frame_mp3on4(). Originally committed as revision 19987 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	15 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
