* 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: include stdint.h instead of inttypes.h.Clément Bœsch2012-11-20
| | | | | | | | | 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.

* 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().

* swr/resample: move templating parameters to template itself.Clément Bœsch2012-11-15
| | | | | | | | | 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.

* lswr/swresample: adopt globally consistent rules for options help messageStefano Sabatini2012-11-03

* swresample: include ff_log2_tab for shared buildsHendrik Leppkes2012-10-20
| | | | | | | | 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>
