Youtube h.264 (MP4) hardware acceleration not working..

  • Hey,
    I have a laptop with:
    Intel GMA 4500MHD
    Core 2 Duo @ 2.93GHz (Penryn)
    4GB DDR2 RAM

    Opera version 38 (latest) with h264ify extension

    Now, I have been trying to get hardware acceleration to work on YouTube videos but it hasn't worked for me... Accelerating a local video works on MPC-HC (the video is a downloaded YouTube video with the same exact format and codec - MPEG 4). Furthermore, H.264 (MP4) YouTube acceleration has been working on Mozilla Firefox 47 and I didn't have to force it to work.

    Graphics Feature Status
    Canvas: Hardware accelerated
    Flash: Hardware accelerated
    Flash Stage3D: Hardware accelerated
    Flash Stage3D Baseline profile: Hardware accelerated
    Compositing: Hardware accelerated
    Multiple Raster Threads: Disabled
    Native GpuMemoryBuffers: Software only. Hardware acceleration disabled
    Rasterization: Software only. Hardware acceleration disabled
    Video Decode: Hardware accelerated
    Video Encode: Hardware accelerated
    WebGL: Hardware accelerated

    Supported features from opera://gpu

    video_decoder WMFVideoDecoder --- From opera://media-internals
    Supports Hardware H264 Decoding Yes --- According to Firefox
    GPU Accelerated Windows 1/1 Direct3D 11 (OMTC) --- According to Firefox

    Could there be a way to force enable Direct3D 11 on Opera since I have the disable_d3d11 flag?

    I really like Opera and I don't wish to drop it over this issue but can someone please help me? ^-^


  • What is your OS?

    Chrome or Vivaldi use hardware acceleration for the same videos?

  • have you tried installing a separate codec pack as MPC-HC comes with it's own built in hence why it probably works Opera only uses codecs available on the system

  • I use Windows 7 Home Premium Service Pack 1 64-bit (Build 7601)
    I have tried H264 video on YouTube on both Chrome and Vivaldi (tried the 64-bit version of Vivaldi aswell).
    Both Chrome and Vivaldi were the latest versions..
    Firefox still works without a problem and my CPU usage is noticably lower since there is video acceleration.


  • So both Chrome and Vivaldi behave the same as Opera? If so then it's a Chromium issue.

  • Oh, there's no way to get around it then?

    I don't know.

  • Oh okay, I guess I'll try new versions of Opera when they come out in hope of it working. Is there any way to open a bug report to Chromium maybe?

    For sure. Probably there is one already.
