Yes, we start a new video whenever the dimension changes. On an
uncongested network, there should be a 10 second low-resolution segment,
and then the resolution stabilises at the highest value. This was already
the case in 0.3, but we were losing the low-resolution segment (the
recording was only started at the second keyframe).
The alternative would be to use a single webm file even though the
resolution changes. This happens to work fine with mpv and vlc, but is
a violation of the Matroška format.

Firefox uses a non-standard protocol for simulcast. I've tried to
implement it (Sean has recently added support to Pion), but it doesn't
work with the version of Firefox currently in Debian, and I don't see
a good way to distinguish the good versions from the bad ones.

Noted, thanks.

Strange. Can you please compare the output of about:gpu in the two
versions of Chrome/Chromium?

Thanks, I'll have a look.
