[Cin] weird svt-av1 / libdav1d interaction

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)
