Comment (by Andrew-R):
https://yadi.sk/d/y_MMRKxzqbEJ1w - out-3.ivy, encoded with "-intra-period
30 -irefresh-type 2" as suggested at https://github.com/OpenVisualCloud
/SVT-AV1/issues/257
sha256sum out-3.ivy
d8b643c3e33cbc7cf02d0fa467140d42ede1ce177e7ac675d5483ba844e7e1ca
It was remuxed by ffmpeg
./ffmpeg -i ../out-3.ivy -vcodec copy -v verbose
../av1_svt_0.5_1000frames-3.web
and after this my test application (https://www.cinelerra-
gg.org/bugtracker/view.php?id=214 - see here my hack for dav1d decode)
play resulted webm correctly (even backward), and can seek without
problems.
ffplay still gives errors at seeking attempt:
