Original GitHub issue: https://github.com/netblue30/firejail/issues/2312

I'm running Ubuntu 18.04, with mpv version mpv git-2018-07-22-45beb70 youtube-dl version 2018.11.07 and firejail version 0.9.56

When I try to watch a YouTube video via mpv, I get the following error:

But running it via /usr/bin/mpv it works fine

I followed
https://github.com/netblue30/firejail#Compile-and-install
Minus the line about apt, as I already had those packages

You still have both the package and the source version installed. In that screencast when you ran mpv, you used the package version.

Please try
/usr/local/bin/firejail mpv ...
