Youtube hardware accelerated video decoding does not work

  • When watching Youtube videos in Chrome and Vivaldi my cpu is using around one full cpu core to decode. Video decode in the taskmanager shows 0% usage.
    When watching Youtube videos in Edge and Firefox my cpu is using around 10% of one full cpu core to decode. Video decode in the taskmanager shows 23% usage.

    I have googled and looked around the forums here but all my settings and flags seems correct. Why doesn't Vivaldi use hardware video decoding?

    @ferdinand8 Your GPU may be blacklisted by Chromium.

  • @Ayespy I don't think so. It is a Pascal card with the latest drivers.

    We have already bug reports resulting in this master bug:
    VB-44138 "Problems with Nvidia GeForce GTX 1080"

  • Moderator

    @ferdinand8 Try if this override may help (yop can reset it of it does not help):

    • Open vivaldi://flags/#ignore-gpu-blacklist
    • Set to Enable
    • Restart Vivaldi

  • @Gwen-Dragon I set ignore blacklist to true and restarted. VP9 is still not accelerated.

    I have tested Brave and Opera too now.

    Browsers that support VP9 acceleration:

    • Firefox
    • Edge
    • Opera
    • Brave

    Browsers that don't support VP9 acceleration:

    • Chrome
    • Vivaldi

    VP9 acceleration has been supported on Nvidia GPU's since the GTX950.

  • @ferdinand8 this one works in Chrome and vivaldi:
