Quick & Easy: Hardware Encoding with VAAPI on Radeon under Ubuntu 23.10 feat FFMPEG

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
crf 24, audio copy

ffmpeg -vaapi_device /dev/dri/renderD128 -i n1.mkv -vf 'format=nv12,hwupload' -c:v hevc_vaapi -qp 24 -c:a copy hevc-crf24.mp4

5mbps, audio copy

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

crf 24, 10-bit, audio copy

ffmpeg -vaapi_device /dev/dri/renderD128 -i n1.mkv -vf 'format=p010,hwupload' -c:v hevc_vaapi -qp 24 -profile:v 2 -c:a copy hevc-main10-crf24.mp4
