Hello,
i am looking for a suggestion on which packages to install in order to enable ffmpeg to use hardware video decoding/encoding functions of the AMD Ryzen 7 PRO 4000 Series processor like 3750GE.
i have already installed packages that i have found suggested:
$ pacman -Q|grep -E “amd|vdp|mesa|cuda”|sort -h

So i have tried command
ffmpeg -i sourcefile -vcodec libx265 destination.mp4
which is the only one that works (at around 70fps), other codecs shows following errors:
[nvenc_hevc @ 0x55785b157e40] This encoder is deprecated, use ‘hevc_nvenc’ instead

::
My aim is to encode to H265 or H264 format using ffmpeg with minimum computing overhead/impact. I was looking for some script that would estimate available accelerators and test its performance, but can not find.
UPDATES:
- following command apparently WORKS:
ffmpeg -vaapi_device /dev/dri/renderD128 -i input.mp4 -vf 'format=nv12,hwupload' -c:v hevc_vaapi -f mp4 -rc_mode 1 -qp 25 output.mp4
source (Arch wiki); FPS is not 70, but 360 and CPU usage monitor does not show any additional CPU usage…! The question is how to tweak these parameters and how to apply it to every H265 encoding of every app on the system.
ffmpeg -help encoder=hevc_vaapi show some parameters details, rc_mode (rate control) seems not needed.
