Your ffmpeg seems to miss functionality, likely vp9 encoding. The --disable-libvpx is likely to blame.

See https://github.com/phw/peek/blob/master/data/flatpak/flatpak-master.json#L37 for a list of minimal configure options that are needed for ffmpeg to support all the features Peek requires.

If you don't want to use MP4 encoding you can do without libx264 and MP4 muxer, but the rest is pretty much required.

Closing this as I think that has been answered. If not please let me know.

You should compile ffmpeg with the flag vpx.
