Michael Niedermayer	9aec63af9b	swr: fix assertion failure if dither is used without the preout buffer differing from in 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

Stefano Sabatini	8bee8f778a	lswr/swresample: use AV_OPT_TYPE_SAMPLE_FMT for sample format options Improve usability and robustness.	12 years ago
Clément Bœsch	52b7823b73	swr: include stdint.h instead of inttypes.h. stdint.h is for the [u]int*_t types, which is the only thing we need for the prototypes. inttypes.h includes stdint.h and defines more thing we don't need here. Bump micro in case a user app was relying on this include for its own code.	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

Clément Bœsch	8ea8833979	swr/resample: move templating parameters to template itself. It has various benefits such as allowing some refactoring, clarifying the code in the inclusion part, and making the template understandable in standalone. This commit is based on the templating method used by Justin Ruggles for libavresample.	12 years ago
Michael Niedermayer	d53f447130	swr: move if() block into the only branch where it can be true. This should make the code a tiny tiny bit faster. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	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

Hendrik Leppkes	04bf2e7f0e	swresample: include ff_log2_tab for shared builds This is done in accordance with all other libraries, which no longer access ff_log2_tab from avutil directly for shared builds, and instead obtain their own copy. This change is required for MSVC DLL builds, as well as avoids accessing a private symbol from another library. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
