Problem capturing VP9

  • Hi everybody,


    I don't know if this is a bug or supported at all but

    capturing VP9 encoded videos via the internal grabber does not work.


    The led visualization live-video screen shows the LibreElec logo but not the playing video.


    The log repeats:


    Playing the same video H264 encoded does work propaply.


    Best regards

    VP9/H265 is usually decoded on the hardware side or not 'normally' in the graphics memory so that the framebuffer grabber gets an image.

  • Hi pclin,


    thanks for explanation!

    Although I would now like to ask the nooby question why it not could simply be copied in the graphics memory? :saint:

    Afaik there is only "normal" RAM and no special GPU Memory on the Pi?

    Best regards
