I have another copy of Tor browser on my PC and it plays SkillShare videos just fine.

But the one on VPS can't play giving an error:

"The video is bad or in a format that can't be played in your browser" media_err_decode

What can be causing the issue?

Everyone's help is greatly appreciated!


  • It probably doesn't have the correct video codecs (codices?) available to decode it. You might need to install gstreamer plugins or whatever the system happens to use.

  • Thanks for your reply. However I have installed Gstreamer, VLC and K-Lite Code Pack on the VPS machine but the videos on SkillShare still don't play. I'm getting the same error code and after I click the OK button the loading wheel just keeps on spinning. What can be different between Tor browser installed on my home PC and Tor installed on VPS? I have checked and the settings are the same. Both are the fresh installations. Thanks. Aug 29, 2016 at 21:36
  • It could be that it's a non-free encoding method that can't be redistributed without a license. .e.g H.264
