wiak -

Install Package

  • sudo apt update
  • sudo apt install libva-dev vainfo ffmpeg mediainfo
  • sudo vainfo | grep EncSlice will show what hardware encoders are supported

Improving performance, might end up being slower (but with less cpu usage) depending on hardware

  • -async_depth 1
  • -hwaccel vaapi (decode in hardware, lowers cpu usage)

H.264/AVC Hardware Encoding using VAAPI on Radeon Vega or later
crf 24, audio copy
ffmpeg -vaapi_device /dev/dri/renderD128 -i n1.mkv -vf 'format=nv12,hwupload' -c:v h264_vaapi -qp 24 -c:a copy avc-crf24.mp4

5Mbps, audio copy

ffmpeg -vaapi_device /dev/dri/renderD128 -i n1.mkv -vf 'format=nv12,hwupload' -c:v h264_vaapi -b:v 5M -c:a copy avc_5M.mp4

H.265/HEVC Hardware Encoding using VAAPI on Radeon Vega or later
