Videos not playing in Vivaldi


  • Vivaldi Ambassador

    Some videos play fine in Vivaldi, but most don't. They look like this:
    most videos
    There is sound but no picture. The problem is only with Vivaldi.

    Here is link to one such video.

    It's same when video is embeded or not.
    embeded

    On this particular website when I scrolled down a bit I could see background webpage through the playing video.
    alt text

    Also some videos on Twitter show only first frame (again there is sound, but picture doesn't change).

    That video plays fine for me, it is vp9 media so my first thought is that you don't have the required codecs (e.g. You may have a Windows N variant).

    If so try https://www.microsoft.com/en-us/download/details.aspx?id=48231

    Otherwise, please provide more information on your setup - which Windows you have, which version of Vivaldi (see help/about); have you installed any extensions or activated any flags/experiments?

    E.g. The strict-site-isolation flag is known to cause problems with embedded videos.

    That is really weird if that happens to you, but the video is working fine for me.

    Please tell us:
    about your Windows
    Graphics card and drivers
    Set any vivaldi://flags

    Try this:
    Open in address field chrome://flags/#disable-accelerated-video-decode
    Set to Enable
    Restart Vivaldi

    Does this help?

    The aforementioned video is now working for me too. And I haven't changed anything in settings yet.

    I use Windows 10.
    Only flag set is to save webpages to mhtml.
    I've got acceleration already as enabled.

    Here is another video with same problem for me.
    The problem appeared in Vivaldi 14 and I was hoping it will be fixed in 15.



  • @hondac That video also plays fine for me!

    I use Windows 10.
    Only flag set is to save webpages to mhtml.
    The problem appeared in Vivaldi 14 and I was hoping it will be fixed in 15.

    So we guess Home or Pro (and not Windows N)!?
    Also guess 1.15 Stable.

    Do we also have to guess

    Graphics card and drivers

    Open in address field chrome://flags/#disable-accelerated-video-decode
    Set to Enable
    Restart Vivaldi

    Did you try with it Disabled?

    If you open vivaldi://gpu

    What is shown under Graphics Feature Status (don't need to show Workarounds or Detected fields)?



  • I came to these forums because I am also having trouble playing certain videos. I have been using this browser for at least 6 months, maybe a year, and I have never been able to play videos imbedded in reddit without it crashing my broswer, such as this one. It will usually play fine if I leave it alone, but if I start to scroll around or pause/play, etc. the browser will slowly crash. Sound usually continues working but the whole browser locks up.

    @selkiekezia After a short search with reddit freeze you could have find this.

    Ther are many bug reports about reddit freeze after scrolling or playing videos.
    We are working on this bug.

    And i get such freeze with your example reddit video on current 1.16 Snapshot, too :(

    We have been working on a fix for Reddit videos and we believe we will have a fix shortly.
