QTKit and DisplayLink

- QTKit

For QC, I use a DisplayLink and QCRenderers.

For that part everything works fine :-)

For QTKit, I would like to run it in different threads.

Why?

First QTKit is far more convenient than the QT C API

Then, I want to display several videos at the same time and for each, follow a playlist and load the movies in advance.

The problem is the following : I can't find a decent thread architecture to make it work.

I followed the QTKit FAQ and load my movies in the main thread (performSelectorOnMainThread)

Then I detach them and re attach them in a thread that does basic things : start/stop for the moment

I call in the thread :

if ([nextChannelMovie respondsToSelector:@selector(setIdling:)])

[nextChannelMovie setIdling:NO];

because the QTKit FAQ recommends this

But if I do it, just the first frames of the movies are rendered. Then it blocks.

If I don't, the app crashes after some seconds on QTKit idle management (which is done in the main thread)

Please note that I removed any MoviesTask call from a timer in the main thread because I found that in the QTQuartzPlayer example that calling QTVisualContextTask(qtVisualContext); after [_openGLContext flushBuffer]; seemed to be enough

Can someone help me finding how to do that idle management correctly?
