* mpegaudiodec: Fix av_dlog() invocation.Diego Biurrun2011-06-01
| | | | | | Some parameters passed to the av_dlog can be either float or int, depending on the mode the file is being compiled as. Cast those parameters to float and use appropriate conversion specifiers.
* mpegaudiodec: remove unusued code and variablesMans Rullgard2011-05-31
| | | | Signed-off-by: Mans Rullgard <mans@mansr.com>
* mpegaudio: clean up compute_antialias() definitionMans Rullgard2011-05-31
| | | | | | | | This merges the float and fixed-point versions of the compute_antialias function, fixes invalid array indexing, and eliminates a dead copy of csa_table. Signed-off-by: Mans Rullgard <mans@mansr.com>
* dct32: Add AVX implementation of 32-point DCTVitor Sessak2011-05-21

* mpegaudio: clean up #includesMans Rullgard2011-05-20
| | | | Signed-off-by: Mans Rullgard <mans@mansr.com>
* mpegaudio: move some struct definitions from mpegaudio.hMans Rullgard2011-05-19
| | | | | | | These structs are only used in mpegaudiodec.c, so move them there and remove no longer needed #include lines from mpegaudio.h. Signed-off-by: Mans Rullgard <mans@mansr.com>
* Move some mpegaudio functions to new mpegaudiodsp subsystemMans Rullgard2011-05-19
| | | | | | | | This separation allows these functions to be used in a cleaner fashion from other codecs (e.g. qdm2) and simplifies creating optimised versions of them. Signed-off-by: Mans Rullgard <mans@mansr.com>
* mpegaudio: sanitise compute_antialias_* namesMans Rullgard2011-05-18
| | | | | | | This makes the compute_antialias functions use the same naming convention as everything else. Signed-off-by: Mans Rullgard <mans@mansr.com>
* mpegaudio: add _fixed suffix to some namesMans Rullgard2011-05-17
| | | | | | | | This adds a _fixed suffix to the fixed-point versions of things with both float and fixed-point variants. This makes it more consistent with other dual-implementation things, e.g. fft. Signed-off-by: Mans Rullgard <mans@mansr.com>
* dct: build dct32 as separate object filesMans Rullgard2011-05-17
| | | | | | | This builds the float and fixed-point versions of dct32 separately instead of #including the file in dct.c and mpegaudiodec.c. Signed-off-by: Mans Rullgard <mans@mansr.com>
* mpegaudio: move OUT_FMT macro to mpegaudiodec.cMans Rullgard2011-05-16
| | | | Signed-off-by: Mans Rullgard <mans@mansr.com>
* mpegaudio: remove OUT_MIN/MAX macrosMans Rullgard2011-05-16
| | | | | | | | These macros are no longer needed after the s32 output was removed. Change the relevant code to use av_clip_int16() instead of using explicit limits. Signed-off-by: Mans Rullgard <mans@mansr.com>
* mpegaudiodec: group #includes more sanelyMans Rullgard2011-05-09
| | | | Signed-off-by: Mans Rullgard <mans@mansr.com>
* mpegaudio: remove #if 0 blocksMans Rullgard2011-05-09
| | | | Signed-off-by: Mans Rullgard <mans@mansr.com>
* mpegaudio: remove CONFIG_MPEGAUDIO_HP optionMans Rullgard2011-05-09
| | | | | | | 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>
* lavc: add missing audioconvert includesAnton Khirnov2011-04-02

* Replace FFmpeg with Libav in licence headersMans Rullgard2011-03-19

* Set channel_layout for mpegaudioKieran Kunhya2011-02-05
| | | | Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>
* Remove a few if (p) av_free(p) formsClément Bœsch2011-02-03
| | | | Signed-off-by: Mans Rullgard <mans@mansr.com>
* Replace dprintf with av_dlogLuca Barbato2011-01-29
| | | | dprintf clashes with POSIX.1-2008
* Add ff_ prefix to data symbols of encoders, decoders, hwaccel, parsers, bsf.Diego Elio Pettenò2011-01-26
| | | | | | | None of these symbols should be accessed directly, so declare them as hidden. Signed-off-by: Mans Rullgard <mans@mansr.com>
* Move ID3v1 skip from decoder to demuxerClément Bœsch2011-01-22
| | | | Signed-off-by: Janne Grunau <janne-ffmpeg@jannau.net>
* Handle ID3v1 tag while decoding mp[123] framesClément Bœsch2011-01-10
| | | | | | patch by Clément Bœsch (ubitux at gmail) Originally committed as revision 26297 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Show correct bitrate for VBR MP3 files.Alexander Kojevnikov2010-07-27
| | | | | | Patch by Alexander Kojevnikov, alexander kojevnikov com Originally committed as revision 24539 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Move ff_dct_init(context) out of if(one time init)Michael Niedermayer2010-07-07
| | | | | | fixes calling a null pointer in issue658 Originally committed as revision 24081 to svn://svn.ffmpeg.org/ffmpeg/trunk
* mpegaudio: move compute_antialias_float() to mpegaudiodec_float.cMåns Rullgård2010-07-01
| | | | | | | | | 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
* mpegaudio: call ff_mpegaudiodec_init_mmx() only from float decoderMåns Rullgård2010-07-01
| | | | | | | | | | | | 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
