background info: with qtcapture or qtsound the Open method hangs (simply doesn't continue) when using -I dummy. as far as my research goes this is due to the fact that QTCaptureSession calls back to the main thread when calling addInput. </div>

when googling this, quicktime engineering replies that QTCaptureSession only posts notifications to the main run loop. [1]</div>

a solution from another list [2] suggests to run a run loop on the main thread otherwise the QTCaptureSession waits forever for the addInput call to complete.</div>

i'm a bit lost and want to fix this in order to work with -I dummy, so i'd be grateful for some starting points. how does -I dummy work? (what a question…) or could this be lost ground as Pierre notes in a commit that one should not expect this to run with
-I dummy [3].</div>
