2014-08-09Bump major versions of all libraries.Anton Khirnov
2014-08-09Postpone API-incompatible changes until the next bump.Anton Khirnov
2014-08-07swscale: Undeprecate sws_getContext()Diego Biurrun
sws_getCachedContext is not a full replacement for the function.
2014-08-04swscale: support AV_PIX_FMT_YA16 as inputVittorio Giovara
Based on a long debug session with Kostya.
2014-08-04avutil: rename AV_PIX_FMT_Y400A to AV_PIX_FMT_YA8Vittorio Giovara
The rationale is that you have a packed format in form <greyscale sample> <alpha sample> <greyscale sample> <alpha sample> and shortening greyscale to 'G' might make one thing about Greenscale instead. An alias pixel format and color space name are provided for compatibility.
2014-08-04swscale: correctly pad destination buffer in rgb conversionKostya Shishkov
Bug-Id: 772 CC: libav-stable@libav.org Found-By: Justin Ruggles <justin.ruggles@gmail.com> Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>
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>
2014-04-12swscale: fix an implementation-defined unsigned-to-signed conversionJustin Ruggles
2014-04-08swscale: support converting YVYU422 pixel formatVittorio Giovara
2014-04-02swscale: add endianness conversion for AV_PIX_FMT_BGRA64|RGBA64Janne Grunau

2014-03-13bfin: Refactor duplicated assembly-related macrosDiego Biurrun
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

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>
