I am writing a simple app that does video capture and vout playback.
Since I'm new to QT and all my mac programming experience is in Cocoa,
I'm trying to merge the two.
I have the sequence grabber done and I am able to get the capturing
vide displaying in a NSQuickDrawView. I was able to do this with
Apple's Sequence Grabber sample code.
I have used the Simple Vout sample code to implement an output. In
both cases I reference the same (subclass of) NSQuickDrawView object
and use [qdview qdPort] in the same way.
Here's the odd thing. I have two of these objects in my app. One does
is connected to my controller, the other is unconnected in IB. If I
remove either one and connect the other to my controller, the sequence
grabber will display in the right place, but the vout echo port will
display in the upper left hand corner of the screen. Not the UL of the
window, but of my monitor.
I've tried any number of things to rectify the situation, but whenever
I remove one or the other object, my vout echo port is dislocated.
Any ideas, anyone?
