But if I go to html5test.com the support wont be available (hence, no youtube streams).
As well I can not install chromium-codecs-ffmpeg (or vivaldi-codecs-ffmpeg, as how it is called now) since this conflicts with the .so file that I mentioned above.
After some years? Is there a workaround available? I found that Mixcloud is not working and must see, YT stream won’t work too. That makes Opera unuseable for me…
There seems to be an option in the opera package that allows you to include proprietary codecs from vivaldi-ffmpeg-codecs, which includes H.264 support. To enable it, you need to override opera:
You don’t actually have to explicitly install vivaldi-ffmpeg-codecs as that will be pulled in as a dependency for opera. Also, overriding opera will still install opera for you, it’s just that you’re including the proprietary codecs with it.
