Twitter videos not playing in 2.8.1664.35

  • Twitter shows "the media could not be played".
    I saw a post from 2016. Why is this still not fixed?

  • @SveBjorn Hello, do you have the problem with all videos on Twitter? Or just part of them? An example to share?
    Do you have extensions installed that could be the origin of the problem? (you can try with those disabled just to verify)
    Not related but you could update Vivaldi to the last version 2.8.1664.40

  • Maybe it's the usual Windows 10 N problem with no proper media codecs pack installed.
    I'm on Win7 32bit and I just played a couple of video clips posted on Twitter, no problems.

    Edit: found one channel posting "gifs" (actually mp4) that display only a circular animation as it's loading forever, but never plays
    and others on (some play, some don't)
    They all play on Kiwi browser on Android.
    VIDEO: [H264] 548x660 24bpp 16.667 fps 792.3 kbps (96.7 kbyte/s)
    I don't see any particular strange thing about it.

    Sorry to hear about your issue and thanks for reaching out. In order to help you we need some more information 🙂

    1. What is your Mac/Linux/Windows version and build?
    2. What is your Vivaldi version? (via Vivaldi menu
      Help → About and first line)
    3. Which CPU and RAM do you have?
    4. Which GPU and graphics hardware do you have?
      Are the drivers from chipset/card manufacturer up-to-date?
    5. Which is the output of vivaldi://gpu – any red or orange warnings?
      Copy the red and orange and paste here.
    6. Which audio output devices or special audio hardware do you use (f.ex. 5.1 surround or others)?
    7. Which extensions do you have installed? (via page chrome://system, row extensions and button Show...)
    8. Which security software do you have running (Firewall, antivirus, malwarekiller, etc)
    9. Which URL causes this issue?

  • Ok something is really not correct in some of those mp4 "gif" in the twitter link I posted, even firefox 69.0.2 don't play them, on both my Win7 PCs. Kiwi on Android plays them all.

  • @Gwen-Dragon I dont like this passive aggressive behavior here. 😞
    I have a Windows Pro installation 32GB ram and a Nvidia quaddro card. Professional DELL CAD mobile workstation that should be capable to render some simple website video.
    I check the proposed solutions. Thanks!

    @SveBjorn Thanks for your reply, please try one step after another to see if it solves your issue:

    • Update your NVidia drivers from NVidia page.
    • Disable all Intel GPU in BIOS.
    • Check special Hardware acceleration in NVidia settings
    • Enable Use of Hardware acceleration in internal page chrome://settings/system and restart Vivaldi
    • Enable override of GPU black list with vivaldi://flags/#ignore-gpu-blacklist, set to Enable and restart Vivaldi

  • @Ornorm Hej. Yes, all videos are not playing. No gif or other format will load.
    I am on Windows 10 with a fairly fresh install - last time after a fresh install I had no issues with twitter. And if a codec is missing - how come Firefox, Edge and Chrome are showing all content? If this is a Vivaldi settings issue I have to find out which one it is.

    they have their own decoding libraries, Vivaldi don't.

  • @iAN-CooG 4b44c09d-b392-4a9e-94b4-9f8e27cc9310-image.png

    Ok. good to know.
    I tried : vivaldi://flags/#ignore-gpu-blacklist
    and tried Override software rendering list.

    Didnt help yet.

    Attached is a screen of a typical tweet.

  • On Windows 10 N You have to install the media codec pack for your Win10 version. I hope this is the correct link

  • @iAN-CooG thanks!

    @SveBjorn Did the installation of Media Feature Pack for Windows N helped you to solve the broken video display?

  • Community Manager

    Also, I also pinged one of our dev who's specialized with media issues and he's recommending to test out with disabled hardware acceleration.
    Does that do the trick?

    Lastly if you are using any extensions, please disable them and check if it works.

    Please let us know how it goes. 🙂
