Added linux support for amf encoder through vulkan.
To use h.264(AMD VCE) encoder on linux amdgru-pro version 19.20+ and
amf-amdgpu-pro package(amdgru-pro contains, but does not install
automatically) are required.
This driver can be installed using amdgpu-pro-install script in
official amd driver archive.
Initialization of amf encoder occurs in this order:
1) trying to initialize through dx11(only windows)
2) trying to initialize through dx9(only windows)
3) trying to initialize through vulkan
Only Vulkan initialization available on linux.
- Intel QSV-accelerated MJPEG decoding
- Intel QSV-accelerated VP9 decoding
- support for TrueHD in mp4
+- Supoort AMD AMF encoder on Linux (via Vulkan)
version 4.2:

-FFmpeg can use the AMD Advanced Media Framework library under Windows
-for accelerated H.264 and HEVC encoding on hardware with Video Coding Engine (VCE).

@url{https://github.com/GPUOpen-LibrariesAndSDKs/AMF.git}.
Create an @code{AMF/} directory in the system include path.
Copy the contents of @code{AMF/amf/public/include/} into that directory.
Then configure FFmpeg with @code{--enable-amf}.

@section AviSynth
FFmpeg can read AviSynth scripts as input. To enable support, pass
static int amf_init_context(AVCodecContext *avctx)
{

+ AMFContext1 *context1 = NULL;
AMF_RESULT res;
av_unused int ret;

av_log(avctx, AV_LOG_VERBOSE, "AMF initialisation succeeded via D3D9.\n");
