c1679d0f2c Added planar RLE chroma subsampling. 2020-01-14 14:06:43 +01:00
Armin Novak
6fd9525823 Implemented chroma subsampling for planar non RLE 
Planar frames that are not RLE encoded can now be decoded if
chroma subsampling is enabled. Partly fixes #5822

5f0943f0fe primitives: add openCL support 
This patch adds the basic infrastructure to have openCL acceleration.
For now only YUV2RGB is implemented but other operations could be
implemented.
The primitives have been massively reworked so that we have an autodetect
mode that will pick the best implementation automatically by performing a
benchmark.

1112e2fffb codec: Set alpha channel to FF if not used (#5431) 
* Formatting

* codec: Set alpha channel to FF if not used

This PR initializes the alpha channel to FF. Before the alpha channel
contained uninitialized memory potentially causing problems when the
image data was used by an alpha channel aware frontend.

41cc2b63cb Move from libavresample to libswresample 
- The libavresample as part of FFmpeg was declared as deprecated in
    favor of libswresample on Dec 25 2017 in commit "lavr: deprecate the
    entire library"
    (c29038f304
    ;
    c29038f304).
    As major Linux distributions (RPM, DEB and Archlinux) provide now
    FFmpeg and libswresample as its part use the libswresample instead of
    libavresample.

bedc1ac4c6 Use libavcodec's VA-API decoding. 
Leverages libavcodec's hw decode support to provide VA-API based
hardware decoding. Depends on the local build of ffmpeg having hardware
VA-API support compiled in and the appropriate libva drivers and
libraries installed.

Provide support for older versions of libavcodec 
My method was to find the LIBAVUTIL_VERSION_* at the commit where the
updated AV_ prefixed constants became available, add one "micro" version
to it, then if it's not at least that version, provide the unprefixed
constant. It just so happens that the same commit introduced all
the AV_* constants.

Fix future ffmpeg support 
The AV_ prefixed constants have been available since
ffmpeg@def97856de6021965db86c25a732d78689bd6bb0 (2015-07-07), or version
2.8.

The non-prefixed constants are set to be removed in the next ffmpeg
release, and were removed in
ffmpeg@302554835e39b79b977ed60c9afe81b44590dfef (2016-12-05).
