    Default can I use Phonon with frame grabber

    I need to display video stream coming from the external device (Picolo frame grabber). The device comes with API and DirectShow sample. Can I use Phonon to play video in real time? I tried to subclass QIODevice, but that's hard because video input board doesn't support Read command, instead it uses callback.
    Did anyone try to use Phonon for streaming video?

    I am afraid it's not very helpful. Should I create my own MediaSource by inheriting? But I don't see which MediaSource functions I need to re-implement. Or should I design my own QIODevice? Then it's not clear how to ensure consistent frame rate.
