Maybe something like this (https://chrome.google.com/webstore/detail/h264ify/aleakchihdccplidncghkekgioiakgal?hl=de) might work as a workaround?

I'm having the same problem on Linux Mint 19 (Ubuntu based) and previously 18.3. I have this output on the JS console: http://i.imgur.com/sfI4a17.png

Thanks for the report Malte. I've just tested this with Falkon 3.1.0 on openSUSE and I can't replicate the issue. Videos play when loaded.

Can you please test and confirm if this issue is still occurring or if this bug report can be marked as resolved. I've set the bug status to "needsinfo" pending your response, please change back to "reported" or "resolved" when you respond, thanks.

Comment 6 Malte 2020-11-22 14:09:17 UTC

Looks like it works now. I'm not sure about the flatpak version, but the repo version in debian testing plays perfectly. 

No vaapi/hwdec, but as far as I know it is experimental (at best) even in Chrome. It does use a lot of OpenGL :-)
