* swscale: Set alpha to opaque for internal palettes.Justin Ruggles2014-04-12
| | | | | | | | | Fixes conversion of pal8 to rgb formats with alpha. Updated references for 2 FATE tests which previously encoded fully transparent images. Based on a patch by Baptiste Coudurier <baptiste.coudurier@gmail.com>
* swscale: fix some undefined signed left shiftsJustin Ruggles2014-04-12
| | | | Based on a patch by Michael Niedermayer <michaelni@gmx.at>

* Remove all SPARC architecture optimizationsDiego Biurrun2014-03-13
| | | | | SPARC is no longer being used in any multimedia-related fields and the VIS optimizations only represent a maintenance burden.

* avutil: Move library version related macros to version.hDiego Biurrun2013-12-26
| | | | This is a more sensible place for these macros.

|
* swscale: provide a default scaler if none is setVittorio Giovara2013-10-05
| | | | | | | | | | Lanczos for general case, sinc for upscaling, Gaussian for downscaling. According to current literature these scalers should be the best quality-wise algorithms for each case. Inspired from a patch by wm4 <nfxjfg@googlemail.com> Signed-off-by: Luca Barbato <lu_zero@gentoo.org>

* swscale: Disallow conversion to GBRP16Martin Storsjö2013-02-11
| | | | | | | | | | | | | This reverts parts of d6d5ef5534d582, that didn't work right. (The tests that were added failed on big endian, and the output looked garbled on little endian as well.) This is due to the fact that the intermediate scaling values (from e.g. hScale8To19_c or hScale16To19_c) are stored as int32_t and thus requires a separate output function, while yuv2gbrp_full_X_c only interprets it as int16_t.
