Sorry for the bad wording, I don’t know English.
SNAP Opera web browser, latest. You can’t play videos, 80% of websites don’t play videos. Videa.hu, Facebook, Twitter, Tik-tok, I only mention the more well-known ones. But the video does not work on 100 websites. Only YouTube works, but even there the video stops after a few minutes and says: This video cannot be played, the browser is not suitable.
Unfortunately, this is a familiar topic to me, the Opera browser on Linux has been working with this error for 5 years. For DEB installation, opera-ffmpeg-codec or another version of chromium-ffmpeg helped, but not always. I ask, what can be done to make Opera play the videos? Test installation Firefox, Vivaldi, even Edge works fine, but Opera does not.
