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>
2011-04-26Add AVX FFT implementation.Vitor Sessak
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>
2010-12-13Return the amount of input data actually used in the qdm2 decoder,Reimar Döffinger
allows playback of files where multiple qdm2 packets have been merged. Originally committed as revision 25943 to svn://svn.ffmpeg.org/ffmpeg/trunk

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

2010-04-20Remove explicit filename from Doxygen @file commands.Diego Biurrun
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

2009-04-07Implement avcodec_decode_video2(), _audio3() and _subtitle2() which takes anThilo Borgmann
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.
