These are still not working on Opera 45. This is on Ubuntu 15.10, so I have to start up another web browser to view these things.
Same problem here... I've installed Opera just yesterday and started having problems with it on the same day... Please support!
Same problem here! Running Ubuntu 16.04LTS and just installed Opera 45.0.2552.635 and many Yahoo vids won't play. It either says can't play video or you get this message: "There was a problem playing this protected content. (Error Code: 3336)
Your browser does not support protected content playback. Please reload the page in another browser. We'd recommend trying Mozilla Firefox ( www.mozilla.org/en-US )"
When will Opera fix this chronic Problem?
Either I. The same problems running Netrunner 17.01. I like Opera, but in this way i'll change for firefox.
sudo apt-get install ubuntu-restricted-extras
Opera's poor html5 support is to blame for your problem.
Either install what freddyavatar suggested, or chromium-codecs-ffmpeg and chromium-codecs-ffmpeg-extra, in case you do not want the extra bloat of gstreamer and flash that ubuntu-restricted-extras installs.
Same here i have problems com facebook videos.
When it is fixed maybe I'll go back to Opera but woth it's current state and support I have to go back to FF
