2009-09-29WMA: fix loop unrolling in decode_exp_vlc()Måns Rullgård
The count can be a non-multiple of 4 after all. Originally committed as revision 20081 to svn://svn.ffmpeg.org/ffmpeg/trunk
2009-09-29WMA: use type punning and unroll loops in decode_exp_vlc()Måns Rullgård
GCC does stupid things if these assignments are done using floats directly, so fill the runs using integer operations instead. Also unroll the loops since the length is always a multiple of 4. Originally committed as revision 20077 to svn://svn.ffmpeg.org/ffmpeg/trunk
2009-09-29WMA: use a table instead of pow() in decode_exp_vlcMåns Rullgård
Originally committed as revision 20076 to svn://svn.ffmpeg.org/ffmpeg/trunk
2009-09-27Drop unused args from vector_fmul_add_add, simpify code, and renameMåns Rullgård
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
2009-09-26WMA: remove some unused variablesMåns Rullgård

2009-06-20Introduce WMACoef typedef for decoded coefficientsSascha Sommer

2009-06-12Move run level decode functionality to ff_wma_run_level_decodeSascha Sommer

2009-05-16Support for getting (i)MDCT output multiplied by a constant scaling factor.Siarhei Siamashka
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
2009-04-17Remove unused variable from wma_decode_block() found by CSA.Michael Niedermayer
Originally committed as revision 18568 to svn://svn.ffmpeg.org/ffmpeg/trunk
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.

2006-12-14Bug fix for crashes when SSE is used on unaligned arrays.Benjamin Larsson
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
