Alexander Strasser	ac25b31ede	lswr: Improve default resampler's default parameters After making some blind tests on a small collection of music samples for home usage. It turned out that the default cutoff was too low. The impact of filter_size was not clearly distinguishable (the results were on the edge) with the music samples but turned out to be clearly audible in some synthetic samples. Thanks to Daniel for helping out with the listening tests. Signed-off-by: Alexander Strasser <eclipse7@gmx.net>	12 years ago
Nicolas George	5f12d5ad78	lswr: improve rematrixing error message. Report channel layout/count for insufficiently determined rematrixing.	12 years ago

Stefano Sabatini	8bee8f778a	lswr/swresample: use AV_OPT_TYPE_SAMPLE_FMT for sample format options Improve usability and robustness.	12 years ago
Clément Bœsch	c02ae48271	swr: set default channel count options to 0. If not set, they will be defined using the channel layout setting, which is much more convenient when using swr_alloc() instead of swr_alloc_set_opts().	12 years ago
Paul B Mahol	1acd2f6ba7	Replace rest of libavutil/audioconvert.h with libavutil/channel_layout.h Also remove it in once case when it is not needed. Signed-off-by: Paul B Mahol <onemda@gmail.com>	12 years ago
Stefano Sabatini	6450c05ba5	lswr/swresample: adopt globally consistent rules for options help message The help text tells what the option does, not what the accepted parameter is. Thus convert strings of the kind: Bikeshed Color to set bikeshed color	12 years ago

Justin Ruggles	7e15df7551	swr: resampling: add filter type and Kaiser window beta to AVOptions	13 years ago
Nicolas George	1d903a5ee4	lswr: channel_map requires input conversion. channel_map is applied between in and postin. Without this test, if the input format is an acceptable internal format, the in->postin conversion is skipped. In the best case, it ignores channel_map, in the worst case it causes an assert failure if the number of channels is changed by the map.	13 years ago
