2014-06-02Remove all Blackfin architecture optimizationsDiego Biurrun
Blackfin is a painful platform to work with, no test machines are available and the range of multimedia applications is dubious. Thus it only represents a maintenance burden.
2014-05-13build: handle library dependencies in configureJanne Grunau
Instead of setting FFLIBS in each library Makefile configure exports FFLIBS-$library in config.mak.
2014-05-03swscale: Fix an undefined behaviourLuca Barbato
Prevent a division by zero down the codepath. Sample-Id: 00001721-google Reported-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org
2014-04-12swscale: Set alpha to opaque for internal palettes.Justin Ruggles
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>
2014-04-12swscale: fix some undefined signed left shiftsJustin Ruggles
Based on a patch by Michael Niedermayer <michaelni@gmx.at>

2014-03-13bfin: Refactor duplicated l1_text/l1_data_B macrosDiego Biurrun
2014-03-13Remove all SPARC architecture optimizationsDiego Biurrun
SPARC is no longer being used in any multimedia-related fields and the VIS optimizations only represent a maintenance burden.

2014-01-14x86: Consistently use cpu flag detection macros in places that still miss itDiego Biurrun
2013-12-26avutil: Move library version related macros to version.hDiego Biurrun
This is a more sensible place for these macros.
2013-12-14doxy: Define a group for libswscale documentationLuca Barbato
Uniform the style and eliminate a warning on newer doxygen version..
2013-11-23swscale: x86: Consistently use lowercase function name suffixesDiego Biurrun
2013-10-05swscale: provide a default scaler if none is setVittorio Giovara
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>

2013-05-06swscale: add support for endianness only conversionJanne Grunau
Use bitfields in FormatEntry array to avoid wasting an int for each flag.
2013-05-06swscale: Use alpha from the right row in yuva2rgba_cMartin Storsjö

Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>
2013-02-11swscale: Disallow conversion to GBRP16Martin Storsjö
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.
