No kidding. I tested with
--cpu-used=8 --tile-columns=4 expecting acceptable speed and awful quality.
The opposite turned out to be true. The speed is still slow. And the quality wasn't bad. It wasn't very good either, but still beets a tuned x265-slower profile with the specific sample I tested (1Mbps / 1080p / 30fps).
Code:
aomenc -o t.webm t.y4m -t 4 --target-bitrate=256 --enable-qm=1 \
--aq-mode=1 --film-grain-test=1 --cpu-used=8 --tile-columns=4
Code:
ffmpeg -i t.y4m -c hevc -crf 38 -preset slower -x265-params \
sao=0:deblock=-2,-2:psy-rdoq=5:qcomp=.75:ipratio=1.25:pbratio=1.18 t.mkv
The quality of
--film-grain-test=1 is impressive. Better than no test, but
--film-grain-test=2 adds too much grain.
On the decoding side. ffav1 should be available soon-ish.
