Stefano Sabatini	334e2e2363	lavu,lavc,lswr: do not hardcode AV_SAMPLE_FMT_NB value when setting sample format max value The constant may change in libavutil but the library may be compiled against an older version, thus rejecting a value which is otherwise supported by the new libavutil. INT_MAX is used here to denote the max allowed value for a sample format. The opt-test code is changed to provide a valid reference example.	11 years ago

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
