* WMA: use a table instead of pow() in decode_exp_vlcMåns Rullgård2009-09-29
| | | | Originally committed as revision 20076 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Drop unused args from vector_fmul_add_add, simpify code, and renameMåns Rullgård2009-09-27
| | | | | | | | | The src3 and step arguments to vector_fmul_add_add() are always zero and one, respectively. This removes these arguments from the function, simplifies the code accordingly, and renames the function to better match the new operation. Originally committed as revision 20061 to svn://svn.ffmpeg.org/ffmpeg/trunk
* WMA: remove some unused variablesMåns Rullgård2009-09-26
| | | | Originally committed as revision 20030 to svn://svn.ffmpeg.org/ffmpeg/trunk

* Introduce WMACoef typedef for decoded coefficientsSascha Sommer2009-06-20
| | | | | | | and change default type to float so that the run level decoding functionality can be shared with wmapro Originally committed as revision 19231 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Move run level decode functionality to ff_wma_run_level_decodeSascha Sommer2009-06-12
| | | | | | so that it can be reused for wmapro Originally committed as revision 19171 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Support for getting (i)MDCT output multiplied by a constant scaling factor.Siarhei Siamashka2009-05-16
| | | | | | | | Scaling (i)MDCT output has no runtime overhead and can be used to improve performance of audio codecs. All the changes are only needed in 'ff_mdct_init' function and slow down initialization a bit. Originally committed as revision 18855 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Remove unused variable from wma_decode_block() found by CSA.Michael Niedermayer2009-04-17
| | | | Originally committed as revision 18568 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Implement avcodec_decode_video2(), _audio3() and _subtitle2() which takes anThilo Borgmann2009-04-07
| | | | | | | | | | | 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. Originally committed as revision 18351 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Use full internal pathname in doxygen @file directives.Diego Biurrun2009-02-01

* Bug fix for crashes when SSE is used on unaligned arrays.Benjamin Larsson2006-12-14
| | | | | | | | | No measureable change in speed. This gave random crashes on Win32 and BeOS. The cause for this bug is that gcc doesn't align the stackframe. Linux and glibc always ensure this to be true thus this never affected Linux. Originally committed as revision 7318 to svn://svn.ffmpeg.org/ffmpeg/trunk
