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

[Guddla Rupesh]

What does uvd, vce, freesync mean in general.

I think vce means video codec engine.

Freesync from AMD is equivalent to Intel quicksync.

I hope that all the above are integrated into AMF.

Is my assumption true. How to enable freesync, vce or uvd and compile
ffmpeg.
