Using AMD GPU

Using CPU

ffmpeg -y -i input.mp4 -c:v libaom-av1 -strict -2 -b:v 3000K -maxrate 6000K -cpu-used 8 -pass 1 -f matroska NUL & \ ffmpeg -i input.mp4 -c:v libaom-av1 -strict -2 -b:v 3000K -maxrate 6000K -cpu-used 0 -pass 2 output_AV1.mkv
NOTE: This is extremely slow!
- This uses the libaom-av1 encoder.
NOTE: AV1 is implemented in libaom and svt-av1.
- Libaom is the reference codec, it produces smaller files than svt-av1 but it is slow.
- The svt-av1 encoder is optimized for speed and produces bigger files than libaom.
