* Move sine windows to a separate fileMans Rullgard2011-03-20
| | | | | | | These windows do not really belong in fft/mdct files and were easily confused with the similarly named tables used by rdft. Signed-off-by: Mans Rullgard <mans@mansr.com>
* Replace FFmpeg with Libav in licence headersMans Rullgard2011-03-19
| | | | Signed-off-by: Mans Rullgard <mans@mansr.com>
* Separate format conversion DSP functions from DSPContext.Justin Ruggles2011-02-02
| | | | | | | This will be beneficial for use with the audio conversion API without requiring it to depend on all of dsputil. Signed-off-by: Mans Rullgard <mans@mansr.com>
* Replace dprintf with av_dlogLuca Barbato2011-01-29
| | | | dprintf clashes with POSIX.1-2008

* WMA: store level_table as floats, use type punning for sign flip in decodeMåns Rullgård2009-09-29
| | | | Originally committed as revision 20078 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Add two more sizes to ff_sine_windows[] and also pad it with NULLs soVitor Sessak2009-09-15
| | | | | | | | that FF_ELEMS(ff_sine_windows[x]) == 1 << x. Fix issue 1384. Originally committed as revision 19862 to svn://svn.ffmpeg.org/ffmpeg/trunk

* Simplify run level decoding:Sascha Sommer2009-06-20
| | | | | | | | | | - remove unneeded vlc code < 0 check - reorder vlc code handling so that the unlikely escape decoding part comes last - move overflow check out of the decode loop - branchless sign conversion Originally committed as revision 19234 to svn://svn.ffmpeg.org/ffmpeg/trunk
