Rob Sykes	41049d07f2	swr: add a lowpass default so that each Resampler can have its own default. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	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

Andrew Wason	e9b1d5ae5e	fix swr_convert buffering of packed audio swr_convert is not properly buffering packed input audio when the output is not large enough, and when resampling is not actually needed (same samplerate and no SWR_FLAG_RESAMPLE). buf_set() is only handling the first channel and leaving the others as-is. Sample program to reproduce the problem is here https://gist.github.com/2431768 Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Michael Niedermayer	44239bd9f2	swr: add a swr_flags AVOption Using swr_flags instead of plain flags will avoid conflicts that arise with plain flags and multiple libs (which all have AVOption flags) Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
