Hardware accelerated decoding and offscreen rendering (QOffscreenSurface / QOpenGLFramebufferObject)



  • I am using Asus Tinkerboard with OS that have Gstreamer support for VPU.
    Working on QT app that does offscreen rendering using QOffscreenSurface / QOpenGLFramebufferObject (scene with videos).

    Would hardware accelerated decoding be utilized when doing offscreen rendering ?
    If yes, how to confirm ?
    if configurable, pls suggest how.

    Thanks



  • according to my measurements, yes offscreen rendering is using hardware acceleration (if available / configured).
