| | | | Deprecated in 07/2012.
* ppc: Restrict some Altivec implementations to Big EndianLuca Barbato2015-05-31
| | | | | In Little Endian the vec_ld/vec_st operations work as expected only for byte-vectors.

* swscale: Properly scale YUVDerek Buitenhuis2014-12-05
| | | | | | | | | | Only shift limited range luma, and always only shift chroma for upconversion. Based off a patch by Michael Niedermayer. Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com> Signed-off-by: Luca Barbato <lu_zero@gentoo.org>
* swscale: fix sign extensions in yuv planar conversionVittorio Giovara2014-10-18
| | | | | | | | | | Casting the left-most byte to unsigned avoids an undefined result of the shift by 24 if bit 7 is set. yuvPlanartouyvy_c and yuvPlanartoyuy2_c are affected. CC: libav-stable@libav.org Bug-Id: CID 732281 / CID 732282

* Postpone API-incompatible changes until the next bump.Anton Khirnov2014-08-09

* swscale: Undeprecate sws_getContext()Diego Biurrun2014-08-07
| | | | sws_getCachedContext is not a full replacement for the function.
* swscale: support AV_PIX_FMT_YA16 as inputVittorio Giovara2014-08-04
| | | | Based on a long debug session with Kostya.
* avutil: rename AV_PIX_FMT_Y400A to AV_PIX_FMT_YA8Vittorio Giovara2014-08-04
| | | | | | | 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.
* swscale: correctly pad destination buffer in rgb conversionKostya Shishkov2014-08-04
| | | | | | | 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>
* Remove all Blackfin architecture optimizationsDiego Biurrun2014-06-02
| | | | | | 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.
* build: handle library dependencies in configureJanne Grunau2014-05-13
| | | | | Instead of setting FFLIBS in each library Makefile configure exports FFLIBS-$library in config.mak.
* swscale: Fix an undefined behaviourLuca Barbato2014-05-03
| | | | | | | | 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
* 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.
* doxy: Define a group for libswscale documentationLuca Barbato2013-12-13
| | | | Uniform the style and eliminate a warning on newer doxygen version..
* swscale: x86: Consistently use lowercase function name suffixesDiego Biurrun2013-11-22
|
* 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>
