  • @ulkoalex Can you check in Firefox and Edge (non-Chromium Edge) please? Check in Vivaldi too.

    Opera uses the Windows Media Foundation to play proprietary codecs. The resolution might not be supported for GPU acceleration in those cases using WMF where Chrome gets away with it because of its full ffmpeg support. Chrome might switch to software decoding for those resolutions where Opera might not be able to. Firefox, Edge, and Vivaldi might behave the same as Opera.

    It'd be interesting to see what others have in opera://gpu for the decode baseline under the Video Acceleration section. An Opera dev has higher values his machine. I know you have a GTX 1070 though.

    Checked Firefox 68.0, 69.0 (64-bit) - played all resolutions.
    Vivaldi 2.7.1628.30 (Stable channel) (64-bit) - same as opera (doesn't play above 2048w or 1088h), and same Video Acceleration Information on vivaldi://gpu page.
    Regarding non-Chromium Edge - are you sure it's available on win7? I only found Chromium-based one for win7.
    Tried Chromium Edge, 77.0.235.17 (Official build) beta (64-bit) - played everything.

    Also, do you know what should affect those Video Acceleration Information params? Like available video RAM/video driver/installed codecs/screen resolution etc

    PS nvm, found this article https://docs.microsoft.com/en-us/windows/win32/medfound/h-264-video-decoder

    Sorry about that. I forgot you had Win7.

    Not sure at the moment. Will try to find out. Since it works in other Chromium browsers (I guess you could check Brave too), and in Firefox (which is supposed to use some WMF stuff too), perhaps Opera and Vivaldi can improve things.

    • Opera 63.03368.66 (stable channel, 64-bit)

    I've been thinking about those questions, too.

    Checked Brave 0.68.132 Chromium: 76.0.3809.132 (Official Build) (64-bit) - plays all resolutions, and it has exactly the same entire brave://gpu/ page as Vivaldi, except for timestamps (and command line) 😀

    Also, found similar issue with h264 decoding here:

    https://social.msdn.microsoft.com/Forums/windowsdesktop/en-US/2b052b4e-b239-459d-9dac-a197593df7db/how-to-play-highres-h264-video-asf-in-wmp-on-windows-7

    WMF has no way of discovering that the decoder is not suitable until too late, it would be up to WMP to check the limitations of the decoder

    So in this case browser should check the video before using decoder and, as you said, switch to software decoding for resolutions unsupported by WMF.

  • @burnout426 so should I report this issue using Bug Report Wizard, or devs already informed about it?

    They're informed about it, but please file a bug so it can be analyzed, and include all the details etc. you can. Also, include a link to this forum thread for good measure. Also, after you've submitted, please post the bug number here. Thanks.

  • For Vivaldi, I submitted VB-56881 (more of an FYI) and pointed to this thread. In https://forum.vivaldi.net/topic/27450/what-is-the-status-of-vb-already-reported-bug-issue, you can ask what the status of it is. I just submitted it, so I'd wait a while before asking.

    Dev/QA that was testing just has a GTX 1050 on Win 10 and 4GB of ram actually. Max Decode resolution for him is 4096x2304 and 2304x4096.

    So, I'm thinking you need Win10 + a fairly-new and decent GPU to get the most out of things at the moment.

    I see, thanks. Yeah, need win 10 at least, as win 7 has resolution limit no matter what GPU you have:

    In Windows 7, the maximum supported resolution is 1920 × 1088 pixels for both software and DXVA decoding.

    😭

  • Just for kicks, try launching Opera with --disable-gpu or just --disable-accelerated-video-decode to see if it does some software stuff with better supported resolutions. It's a long shot, but you can try it.

    Try messing with opera://flags/#use-angle and chrome://flags/#d3d11-video-decoder too if you haven't.

  • @burnout426 hey, appears it was some kind of glitch with my system - now Opera plays all resolutions, as well as Vivaldi (Video Acceleration Information or any other params didn't change).
    I'm trying to reproduce the issue again, but for now it just started working lol (and I didn't even reboot this time)
    My apologies for taking your time, and thanks for your input on the issue. I'll write back if I have more info.
