  • I started to notice a problem few days ago, I didn't have earlier. Some video on youtube, are showing only black screen, and audio is playing, as long as the timeline is moving. I tried login again to my account, restart the browser, clear the history, reinstall player flash, and nothing helped. So this is happening only with SOME videos, while others are just fine.

    Also, other browser, like firefox, are playing that same videos, without a problem.

    Opera is my primay browser for a years. How can I solve this?

  • @milan64586
    YouTube shouldn't be using the Flash Player now, it should be using HTML5.
    Right click on a video and see what pops up.
    Is it the Flash Player information, or HTML5 information?
    For the black videos, try turning the hardware acceleration off in Opera's settings as a first test.

  • @davehawley thanks, this hardware acceleration was causing the problem. Don't know why it wasn't cauising it before.

  • @milan64586
    Well at least that's a workaround!
    Why the hardware acceleration would be suddenly causing a problem when it wasn't before is an issue of course, but I'm sure similar things have been reported here before, so try doing a search for other reports of similar problems.

  • @milan64586 This is a bug of Opera ver.51 in the previous version all ok!
