vivaldi does not stream webcam video

  • Hi there,

    I am using vivaldi 1.14.1036.3 (Offizieller Build) (32-Bit) on Windows 10 (1709).

    I have some strange issues, that vivaldi does not stream the video of my connected webcam (logitech c920) at flash based websites.
    Mostly the video will just stay blank, only sound is working through the mic of the same camera.

    Vivaldi itself and the flash plugin did ask for webcam and mic access, which I did allow. If I check the settings on this particular sites, flash, camera, microphone is allowed.

    Other apps like skype or google chrome, firefox (Accessing the same site) just do work fine.

    I did some tests at this site:

    Hope it is okay to post it here.

    Appreciate your help and tips.

  • Hi,

    yes gwen, I enabled everything as it is described in this article.

    Tested it with another logitech webcam too, problem still exists.

    uninstalled the cam, the cam software, vivaldi and installed the 1.13 version from the website, but it did not work aswell.

    Same cam and version of vivaldi browser works on windows 7 64 bit system.

    I will try the bug report. Thanks.

    Depends which streaming format and video codec is used by the cam.
    On your working Windows 7 did you install special codecs packs?
    On not-working Windows 10. Is this Windows 10 N?

  • I need to apologize.

    I found the problem. My Antivirus Software Bitdefender was the problem. It quietly blocked webcam access for vivaldi, without notify me.

    Disabling this feature did resolve the issue.

    Sorry for wasting your time. Thumbs up for putting much effort in helping people here.

    @uhavefun Thanks for feedback.
    Unfortunately some AV software do "secure" too much.
