 https://bugzilla.mozilla.org/show_bug.cgi?id=1371247 makes me itch + that
 the exoplayer shipped is rather old. I wonder whether there were some
 security vulnerabilities fixes meanwhile (I almost bet that there were).

 Also, so it's documented. It looks like the current shipped version is
 `r2.4.0`. Exoplayer is now at `r2.9.6`.
