Hello,
I'm on guix system with the latest `qutebrowser' from the official
channel. While reading this [site] I realize that embedded mp4 files do
not play well. Turning on qb again from the terminal allowed me to see
the complaints. I believe this could be related issues to OP, so decided
to post it here.
