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.
Linux distributions often require additional multimedia codecs to play certain types of videos. You mentioned opera-ffmpeg-codec , but there might be other codecs required as well. Double-check that you have all necessary multimedia codecs installed for your distribution.
Language, I looked it up.Linux, unfortunately there is NO language setting for Opera, I think this is stupid because it is on Windows.It uses the language of the installed system, but since it is a snap container, it is so dumbed down that it cannot determine the language localization.Solution:
Oh, classic but understandable mistake to make, as this runs outside snap confinement. We should make it clear when people launch the wrong binary, I believe there is really no indication it is not to be used.
