* swr: limit buffer size for discarding.Michael Niedermayer2013-01-13
| | | | | | | This prevents insane memory usage in case of insane input values. Untested due to lack of a testcase that causes such insane allocation Signed-off-by: Michael Niedermayer <michaelni@gmx.at>

* lswr: Improve default resampler's default parametersAlexander Strasser2013-01-04
| | | | | | | | | | | | | | 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>

* swr: set default channel count options to 0.Clément Bœsch2012-11-19
| | | | | | 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().

* lswr: channel_map requires input conversion.Nicolas George2012-07-17
| | | | | | | | 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.
