| Hi Pro Apps Team:
I'm combining a series of core image CIImages together in a CIContext using Open GL. Everything is vertically flipped. This doesn't happen using the same piece of code with my own CIContext in Open GL in a stand alone application. Therefore, it's not the code, but something specific to FCP.
Are you guys doing anything special to the Open GL context that makes it get flipped in FCP. Also, multiple calls to CIContext drawImage seem to not display the alpha channel properly. The Alpha channel in the second call doesn't composite with the first drawImage call. Can I change the Open GL context settings without messing everything up in Final Cut?
[_contextToUse drawImage:videoFrameImage inRect:imageRect fromRect:fromRect];
fromRect = [overlayVideoImage extent]; //fromRect = imageRect;
[_contextToUse drawImage:overlayVideoImage inRect:imageRect fromRect:fromRect];
