First of all sorry if this is a duplicate question, but during my search
online i haven't found a solution.
Hello, i have a problem, my CPU is pretty slow so i wanted to try use VAAPI
encoding for rtmp streaming. (On the side note, using vaapi is kind of
counter intuitive, but that can be ju me being a newbie) Regardless of what
i try i get an error. Searching online i haven't found any information, but
here's the same error even without streaming, but direct copy paste from "
https://trac.ffmpeg.org/wiki/Hardware/VAAPI" of the middle screen capture
$ ffmpeg -vaapi_device /dev/dri/renderD128 -f x11grab -video_size 1920x1080
-i :0 -vf 'format=nv12,hwupload' -c:v h264_vaapi -qp 24 output.mp4
And this was the complete output:
