2013-10-04cosmetics: Group .name and .long_name together in codec/format declarationsDiego Biurrun
2013-07-28qdm2: Whitespace cosmeticsLuca Barbato
2013-07-09qdm2: Conceal broken samplesLuca Barbato
Reported-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org
2013-07-09qdm2: refactor joined stereo supportLuca Barbato
qdm2 does support only two channels. Loop over the run once. Reported-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org
2013-07-08qdm2: check and reset dithering index per channelLuca Barbato
Checking per subband would have the index exceed the dithering noise table size. Reported-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org
2013-07-08qdm2: formatting cosmeticsLuca Barbato
Apply the usual style plus drop few unnecessary return at the end of void functions.

2013-02-12qdm2: decode directly to the user-provided AVFrameJustin Ruggles
2012-12-05lavc: add a wrapper for AVCodecContext.get_buffer().Anton Khirnov
It will be useful in the upcoming transition to refcounted AVFrames.
2012-11-11Include libavutil/channel_layout.h instead of libavutil/audioconvert.hJustin Ruggles
Also reorder some other #include when applicable.
2012-11-01qdm2: remove unneeded checks for channel countJustin Ruggles

2012-05-07qdm2: clip array indices returned by qdm2_get_vlc().Ronald S. Bultje
Prevents subsequent overreads when these numbers are used as indices in arrays. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org Signed-off-by: Justin Ruggles <justin.ruggles@gmail.com>
2012-04-14qdm2: fix a dubious pointer castMans Rullgard
This reworks a loop to get rid of an ugly pointer cast, fixing errors seen with the PathScale ENZO compiler. Signed-off-by: Mans Rullgard <mans@mansr.com>

Signed-off-by: Mans Rullgard <mans@mansr.com>
2012-04-12qdm2: use get_bits_left()Mans Rullgard
Signed-off-by: Mans Rullgard <mans@mansr.com>
2012-04-06cosmetics: Align codec declarationsMartin Storsjö
Also break some long lines, remove codec function placeholder comments and add spaces in sample/pixel format lists. Signed-off-by: Martin Storsjö <martin@martin.st>
2012-01-26qdm2: Check data block size for bytes to bits overflow.Alex Converse
Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org
2011-12-22Drop ALT_ prefix from BITSTREAM_READER_LE name.Diego Biurrun
The prefix is a historic remnant that probably meant "alternative". Now that the A32 bitstream reader has been dropped it makes no sense anymore.
2011-12-03Add avcodec_decode_audio4().Justin Ruggles
Deprecate avcodec_decode_audio3(). Implement audio support in avcodec_default_get_buffer(). Implement the new audio decoder API in all audio decoders.
2011-10-04qdm2: check output buffer size before decodingJustin Ruggles

2011-07-14doxygen: place empty line between brief description and detailed descriptionDiego Biurrun
Without it, Doxygen cannot separate them into different sections.
2011-06-20qdm2: Fix alignment of local array.Michael Niedermayer
Fixes ticket270 Signed-off-by: Michael Niedermayer <michaelni@gmx.at> Signed-off-by: Anton Khirnov <anton@khirnov.net>
2011-05-20qdm2: Use floating point synthesis filter.Vitor Sessak
This avoid needlessly convertion from floating point to fixed point and back. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>
2011-05-19Move some mpegaudio functions to new mpegaudiodsp subsystemMans Rullgard
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>
2011-05-17mpegaudio: add _fixed suffix to some namesMans Rullgard
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>
2011-05-17qdm2: include correct header for rdftMans Rullgard
Signed-off-by: Mans Rullgard <mans@mansr.com>

Signed-off-by: Reinhard Tartler <siretart@tauware.de>
2011-03-19fft: remove inline wrappers for function pointersMans Rullgard
This removes the rather pointless wrappers (one not even inline) for calling the fft_calc and related function pointers. Signed-off-by: Mans Rullgard <mans@mansr.com>
2011-03-19Replace FFmpeg with Libav in licence headersMans Rullgard
Signed-off-by: Mans Rullgard <mans@mansr.com>
2011-01-26Add ff_ prefix to data symbols of encoders, decoders, hwaccel, parsers, bsf.Diego Elio Pettenò
None of these symbols should be accessed directly, so declare them as hidden. Signed-off-by: Mans Rullgard <mans@mansr.com>

SampleFormat with AVSampleFormat. Originally committed as revision 25730 to svn://svn.ffmpeg.org/ffmpeg/trunk
2010-08-24Fix undefined expressions that use multiple calls to get_bits().Alex Converse
Because the order of evaluation of subexpressions is undefined, two get_bits() calls may not be part of the same expression. See also r24902. Originally committed as revision 24906 to svn://svn.ffmpeg.org/ffmpeg/trunk

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
2010-03-31Define AVMediaType enum, and use it instead of enum CodecType, whichStefano Sabatini
is deprecated and will be dropped at the next major bump. Originally committed as revision 22735 to svn://svn.ffmpeg.org/ffmpeg/trunk
