[FFmpeg-user] AMD Ryzen 5500GT APU video processing libraries and Linux ffmpeg video encoding.

[Guddla Rupesh]

I have some problems in my Linux system installing amf using amdgpu-install.


Someone suggested as follows


to enable AMF in ffmpeg, try the follwing:


$ git clone https://github.com/GPUOpen-LibrariesAndSDKs/AMF

$ sudo mkdir -p /usr/include/AMF

$ sudo mv AMF/amf/public/include/* /usr/include/AMF

$ rm -rf AMF

$ cd /path/to/FFmpeg

$ ./configure --enable-amf ...

&& make


Can I follow this procedure.
