Patches for intel svt components will be different at each
component release, so they better be versioned.
This commit updates intel-svt-av1 patch from version 0.5.0
to 0.6.0.
libaom 1.0.0 was released and now upstream ffmpeg is accepting
to compile with this stable version, which was not possible with
libaom 0.1.0.
This will remove the dependency on a -git package, which is good
and desirable when possible.
opencl: opencl-icd-loader was replaced by ocl-icd. Although ocl-icd
currently provides opencl-icd-loader, let's use the newer
approach by depending directly on ocl-icd.
opengl: it seems that the best approach for depending on libGL is
to use libgl instead of mesa. Currently it is provided by
libglvnd package (or by nvidia-340xx-utils for legacy
nvidia users).
At the time of ffmpeg 4.0 release, the latest version of vmaf was
1.3.1. At that time, ffmpeg 4.0 needed vmaf git master to compile.
Now vmaf 1.3.4 was released and ffmpeg builds fine with it.
Since intel-media-sdk is needed not only for building with
Intel QSV support but also for Intel QSV to work during runtime, it
makes sense to stay in depends as a needed component. Forgot to do
it in previous commit. Another option instead of placing it only in
depends would be to place it in makedepends + optdepends because
ffmpeg runs without intel-media-sdk installed (libmfx.a is a static
dispatcher library that calls other sdk components at runtime).
Currently I'm sticking with the depends-only solution.
intel-media-sdk, the open source version of
intel-media-server-studio, has now reached an acceptable stable
release that can be used here to provide libmfx.
This brings 2 important results:
1) The experimental state can be removed from the Intel QSV
support, since intel-media-sdk also provides libmfxhw64
and plugins for hardware accelerated decode and encode.
2) Finally we can get rid of the unsecure rpath in ffmpeg
binaries!
intel-media-sdk is now a makedepend, instead of an optdepend
as previously. If fact, I should have switched it to
intel-media-server-studio in optdepends some time ago when
it has changed to the open source version, but I letted this
way while waiting for an acceptable stable release of, which
taked a while to happen.
Users should remove the libmfx{-git} package and stay only with
intel-media-sdk{-git} package, since the former is the complete
solution with the dispatcher library (libmfx.a), libmfxhw64 and
plugins.
Note1:
------
For the proper use of Intel QSV in ffmpeg the user must set the
vaapi/libva driver to 'iHD' through the 'LIBVA_DRIVER_NAME'
environment variable. The 'iHD' vaapi/libva driver is provided by
intel-media-driver{-git} package, which at the current time is
already a dependency of intel-media-sdk{-git} package. Setting
the vaapi/libva driver to 'iHD' can be done, for example, by
uncommenting the proper line in '/etc/profile.d/intel-media.sh'.
Note2:
------
intel-media-sdk is currently at a pre-release state. This can
lead to bugs when using Intel QSV.
Note3:
------
Not all Intel platforms are supported by intel-media-sdk. At the
current time, it claims to support only 5th and 6th Generation
Intel® Core™ processors (Broadwell and Skylake). For details,
please see the MediaSDK and media-driver documentation:
- https://github.com/Intel-Media-SDK/MediaSDK/
- https://github.com/intel/media-driver/
Note4:
------
Intel QSV is available in x86_64 systems only.

--------------------
- depends: moved 'libbs2b' and 'sndio' from the AUR section to
the official repositories section, since they are now at the
[community] official repository.
