Hi Todd.
FWIW, I have a LSBackgroundOnly application that uses QTKit. Instead of
NSApplicationMain(), I do [[NSApplication sharedApplication] run].
Perhaps that's not exactly what you want, but pretty close. It does suggest you
might be able to get away with, say, running the run loop man

I don't know anything about QTKit. I think I'll try not saying anything about
it.

Xcode 4 Unleashed: Don't bring you
Probably a naive question, but can I use QTKit (or is there a better library?)
to capture images (or videos) inside a UNIX helper application?
I've never tried using Cocoa (and related) objects outside a regular Cocoa
application with a GUI, NSApplicationMain(), etc. Is this gene
track into the "video only" movie ?
I'm really new to Cocoa and QTKit...
Thanks.

Hello,
I create my movie this way:
QTMovie* qtMovie = [[QTMovie alloc] initToWritableFile: path error:
&nserror];
NSDictionary* attributes = [NSDictionary dictionaryWithObjectsAndKeys:

Thanks :)
I really should not code at the end of an 16 hour day, it seems to make me
blind….

I'm using QTMovieView, and it plays fine. But I can't see how I can get called
when it finishes. I expected to see some sort of delegate protocol, or failing
that a property I could observe, but neither of these things app

This makes me think that you're not talking to the object that you think you
are... ;-)
NSZombieEnabled has been useful when tracking down similar cases in the past.
Good luck!

I keep getting an exception from QTKit when quickly moving through a playlist
of songs. Here is the console log and the portion of my code where the
exception is thrown. I am using garbage collection on Snow Leopard.

Thanks in advance,

Matthew,
I believe that the zoom button being referred to by this method is the zoom
button on the QuickTime VR movie Controller. Is the movie being displayed in
your QTMovieView linear or a VR movie?
If your movie is linear, then you can scale it using one of the following:
- use a layer-bac
I'm using a QTMovieView in my project and a user would like be able to zoom in.
Looking at the API there seems to be a
setZoomButtonsVisible: selector, but it doesn't seem to work on my set up. Does
this only work if they have bought QT Pro? I'm on the latest snow leopard, and
I notice it says

If you're not using QuickTime for a specific purpose, try just using NSSound.
