Intel has open-sourced a vp9 encoder with claimed speeds much better
than libvp9. Has anyone used it with ffmpeg ?
The svt-vp9 README has:
ffmpeg -i [input.mp4] -nostdin -f rawvideo -pix_fmt yuv420p - |
./SvtVp9EncApp -i stdin -n [number_of_frames_to_encode] -w [width] -h
[height]
Which would give the compresssed video, but how would I remux it with
the audio ?
Which format does SvtVp9EncApp save as? raw bitstream? IVF ?
Assuming it's IVF,
ffmpeg -i file.ivf -i input.mp4 -c copy -map 0:v -map 1:a remuxed.mp4
If rawvideo,
ffmpeg -f rawvideo -c:v vp9 -i file -i input.mp4 -c copy -map 0:v
-map 1:a remuxed.mp4
