Is there a way to enable this codec support for Opera?
I installed opera via nix-env. As far as I understand, it needs ffmpeg to be available, which I see here as well:
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.
Thanks a lot in advance!
