For those interested, that problem was due to a problem with the Widevine DRM plugin, which is used by e.g. Netflix and Amazon Prime to protect their content, but not by YouTube.

I can watch fullscreen in both of them with no issues.

I can now stream netflix and prime video but I am still having the problem that the film cuts in half and then switches sides in fullscreen. Anyone else have this problem? I can't attach a screenshot because as soon as you press any keys it goes back to normal for about 5 seconds.

@avl

Thank you to all involved in helping to resolve this video playback issue..

The latest
Opera
Version: 64.0.3417.61

is now streaming Netflix, and Amazon Prime videos and doing well with other videos I had issues with even before the 64.* update.

Also, I was making the mistake of not exiting and restarting Opera after running the terminal command:

defaults write com.operasoftware.Opera OPDisableAutoUpdate true

or

defaults write com.operasoftware.Opera OPDisableAutoUpdate false

So that was fun to learn as well. 🙂

I also just exited so the update can be turned on again. Thank you and for the updates!

We're aware of the issue and it'll be fixed in the next update to Opera.

For people struggling with automatic update, it's much easier to disable it like this (and easy to revert later too):

Open Terminal.app and write

defaults write com.operasoftware.Opera OPDisableAutoUpdate true

Would you or anybody be able to post the command to reverse the above command you just posted?

I prefer Opera to Safari, Chrome and Firefox. I upgraded to Catalina a week ago, and have had numerous issues. I can watch videos in some sites but not all, Youtube is fine, however some sites say, HTML5 video not found. I've checked the same site on other browsers and the videos play fine. I'd prefer to stick to Opera for my needs. I downloaded the latest version of Firefox and it keeps freezing up. I prefer not to call to call Geek Squad to fix a few of the these issues. So if anyone knows of a fix or a suggestion, I'd much appreciate the help. Thank you.

I deleted Opera 64, downloaded and installed 63.0.3368.94 from the FTP index and let it update to 63.0.3368.107 - Before launching Opera again I used the the terminal commands you suggested, and that's it... I get the message "An error occurred while checking for updates" when checking "About Opera" in the menu, but it stays put in that version. Netflix and Prime Video now work fine. ☺ Thanks!!

The shell command to disable autoupdate didn't work. Deleting the autoupdate from inside the Opera.app would cause a file is corrupt error.

What did work was using terminal to zero out the update files after downloading and installing the Opera.app.

echo "" > /Applications/Opera.app/Contents/MacOS/opera_autoupdate
echo "" > /Applications/Opera.app/Contents/MacOS/opera_updateinstaller
echo "" > /Applications/Opera.app/Contents/Versions/63.0.3368.107/Opera\ Framework.framework/Versions/A/Helpers/opera_autoupdate

You will need to change 63.0.3368.107 to the version of Opera you wish to run, but disable the autoupdate.

Hope this helps.

By enabling "Use FFmpegDemuxer to demux all media files" in "opera:flags", the problem was solved for me. Maybe it works also for Tumblr.
It doesn't solve the Netflix problem.

Nasty, embarrassing regression. If you look at other threads on Opera for Mac forum - there are more issues with video playback on Catalina. I guess someone forgot to extend test matrix with new OS, even though it was in beta for quite a while.
Shame on you, Opera. Hopefully we'll see a fix soon.

If I quit, and run terminal command again, it still tries... As soon as I reconnect, Opera gets the update... My guess is that it is a combination: Opera 64 does not work well with Netflix and Prime Video, and MacOS Catalina is preventing me from disabling Opera auto update...
