Video showing the problem
I re-encoded the video with this 2-pass method (executing two commands one
after the other:
ffmpeg -i LO-bug-105271-supporting-video-v2.webm -c:v libvpx-vp9 -pass 1 -b:v
200K -threads 1 -speed 4 -tile-columns 0 -frame-parallel 0 -g 9999 -aq-mode 0
-an -f webm /dev/null
ffmpeg -i LO-bug-105271-supporting-video-v2.webm -c:v libvpx-vp9 -pass 2 -b:v
200K -threads 1 -speed 0 -tile-columns 0 -frame-parallel 0 -auto-alt-ref 1
-lag-in-frames 25 -g 9999 -aq-mode 0 -c:a libopus -b:a 64k -f webm
