So, I was testing libsvt-av1 1.8.0 on aarch64

ffmpeg -i 20081103140154.m2t -s 160*120  -c:v libsvtav1 -preset:v 13 av1-1.mkv

it produces seemingly valid file, but I only can play ot with libaom decoder, not libdav1d (as packaged by termux)

~ $ mpv av1-1.mkv -vo tct --vid=1  (+) Video --vid=1 (av1 160x120 25.000fps)  (+) Audio --aid=1 (vorbis 2ch 48000Hz)                         Error while decoding frame! [ffmpeg/video] libdav1d: Error parsing frame header [ffmpeg/video] libdav1d: Error parsing OBU data

it works if I run it via libaom decoder

mpv av1-1.mkv -vo tct --vid=1 --vd=libaom-av1  (+) Video --vid=1 (av1 160x120 25.000fps)  (+) Audio --aid=1 (vorbis 2ch 48000Hz)

(no errors)

I posted small file to termux issue tracker, hopefully you can get it by right clicking on video and selecting save file.

github does not like mkv, so I re-made same file as webm.

also posted at libdav1d repo:

Without any study, I simply found that VLC did playback my SVT-AV1 webm files more clean and smoothly than the visible stuttering default Gnome videoplayer (Totem).
