I suspect, I may have to do that at some point but we’ll see; the FFMPEG-VAAPI may even be community developed and nothing to do with AMD which makes the encoder situation at AMD even worse.
After 2days of playing around with OBS, I finally managed to find passable settings ithat don’t overload the encoder (I still find this odd seeing that the CPU is hardly under any kind of serious load even when gaming).
Testing an upload to YouTube now to see if the file is recognized or accepted. I had to turn down the frame rate to 10 fps and use the bilinear downscale filter in the Video options in OBS to get it stable using
- bit rate of 10000 Kbps,
- CPU usage preset of superfast,
- profile of high, and
- zerolatency Tune
These seemed to get best visual quality results for game capture which I am treating as my stress test. Figured if that works, then other video capture should be fine and I can increase bit rates and other things as needed.
