Summary of the bug:
How to reproduce:
{{{
% ffmpeg -i input -c:v libvpx-vp9 -profile:v 0 -level 2.1 -vf scale=640:-2
output
ffmpeg version N-91941-gf3b430e0e4 Copyright (c) 2000-2018 the FFmpeg
developers
built with gcc 7 (Debian 7.3.0-5)
...
}}}
The VPCodecConfigurationRecord in the output file contains a level of
0x21. It should be 21 instead. See https://www.webmproject.org/vp9/mp4/.
I am working on the fix.
