Marton Balint	741aca7936	libswresample: introduce int swr_set_compensation() instead of void swr_compensate() The new version returns AVERROR(EINVAL) is the specified paramters are invalid, and also creates the resampler if none was used so far.

Michael Niedermayer	b5875b9111	Add libswresample. Similar to libswscale this does resampling and format convertion, just for audio instead of video. changing sampling rate, sample formats, channel layouts and sample packing all in one with a very simple public interface.

Diego Biurrun	ba87f0801d	Remove explicit filename from Doxygen @file commands. 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	15 years ago
Carl Eugen Hoyos	a882cf9c21	Make av_build_filter static (and remove av_): It is not used outside resample2.c. Originally committed as revision 22118 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	2efcf29275	Stop the approximation in bessel() once it does no longer improve. This is faster. Originally committed as revision 21038 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Benoit Fouet	6d69a653d8	Move av_class to AVResampleContext instead of ReSampleContext. Fixes issue 852. Originally committed as revision 18170 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago

Diego Biurrun	bad5537e2c	Use full internal pathname in doxygen @file directives. Otherwise doxygen complains about ambiguous filenames when files exist under the same name in different subdirectories. Originally committed as revision 16912 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
