Michael Niedermayer	6c6e4dd139	swr: check that the context for swr_convert() has been initialized Reviewed-by: ubitux Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Michael Niedermayer	a66be60888	swresample: add swr_is_initialized() Idea-from/based-on: `7e86c27b4e` Reviewed-by: ubitux Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Michael Niedermayer	f284e2a58a	swresample: factorize clear_context() out Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
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

Stefano Sabatini	904c89ac1b	lswr/swresample: convert ocl and icl options to AV_OPT_TYPE_CHANNEL_LAYOUT Improve interface flexibility. In particular makes it possible to set channel layout through symbolic names using the av_opt_set() interface.	11 years ago

Michael Niedermayer	167af704ea	swr: limit phase_shift to a less insane value. This prevents potential crashes and out of memory issues if the user manually sets such insane values. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 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

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
