Yes. What I meant by that remark was that there seems to be no way to access individual movie frames, which would be convenient if I have to implement a 'movie view' myself. >> Ultimately, the only approach left at this moment seems to be to create a >> movie playback view myself using Quartz?

I've given animationImages a try, and although performance is good I run into memory warnings when the array contains about 30 full screen images (1 Sec. worth). I've tried to implement my own NSView subclass -- managing memory for UIImages or CGImages more strictly -- but I've not been able to attain acceptable frame rates (yet). If drawing and memory usage can be optimized by using OpenGL directly I would be grateful for tips or examples. My app uses frame based animation, so I think Core Animation probably doesn't apply. patrick_______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
