Hi. This is the Browser affected:
8.0.8 (based on Mozilla Firefox 60.6.1esr) (64-bit)
I use an Arch Host with Virtualbox running Whonix-Workstation-XFCE and have not tried TorBrowser outside of vBox.
For testing purposes I installed vlc, some ffmpeg and gstreamer libs etc. Didn’t helped.
There are no errors shown in the browsers console.
Videoplayback fails every test listed here:

If I click to a specific position two frames are played and it stops again. No matter if embed with html5 or directly opened within the browser.
edit: Upgrading Torbrowser to 8.5a10 (based on Mozilla Firefox 60.6.1esr) (64-bit)
doesn’t change anything.
