| | | | | | | | | | 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>
* qdm2: fix a dubious pointer castMans Rullgard2012-04-131-5/+6
| | | | | | | 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>

* cosmetics: Align codec declarationsMartin Storsjö2012-04-061-8/+8
| | | | | | | 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>
* qdm2: Check data block size for bytes to bits overflow.Alex Converse2012-01-261-0/+4
| | | | | | Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org
* Drop ALT_ prefix from BITSTREAM_READER_LE name.Diego Biurrun2011-12-221-1/+1
| | | | | The prefix is a historic remnant that probably meant "alternative". Now that the A32 bitstream reader has been dropped it makes no sense anymore.
* Add avcodec_decode_audio4().Justin Ruggles2011-12-021-14/+18
| | | | | | Deprecate avcodec_decode_audio3(). Implement audio support in avcodec_default_get_buffer(). Implement the new audio decoder API in all audio decoders.

* doxygen: place empty line between brief description and detailed descriptionDiego Biurrun2011-07-141-0/+1
| | | | Without it, Doxygen cannot separate them into different sections.

* qdm2: Use floating point synthesis filter.Vitor Sessak2011-05-191-17/+12
| | | | | | This avoid needlessly convertion from floating point to fixed point and back. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>
* Move some mpegaudio functions to new mpegaudiodsp subsystemMans Rullgard2011-05-191-1/+5
| | | | | | | | 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: add _fixed suffix to some namesMans Rullgard2011-05-171-3/+3
| | | | | | | | 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>

* fft: remove inline wrappers for function pointersMans Rullgard2011-03-191-1/+1
| | | | | | | 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>

* Add ff_ prefix to data symbols of encoders, decoders, hwaccel, parsers, bsf.Diego Elio Pettenò2011-01-261-1/+1
| | | | | | | None of these symbols should be accessed directly, so declare them as hidden. Signed-off-by: Mans Rullgard <mans@mansr.com>
* Return the amount of input data actually used in the qdm2 decoder,Reimar Döffinger2010-12-131-1/+1

* Fix undefined expressions that use multiple calls to get_bits().Alex Converse2010-08-241-1/+2
| | | | | | | | | 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

* Remove explicit filename from Doxygen @file commands.Diego Biurrun2010-04-201-1/+1
| | | | | | | | 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
* Define AVMediaType enum, and use it instead of enum CodecType, whichStefano Sabatini2010-03-301-1/+1
