Processing frames captured in OpenCV
Sep 12th, 2009, 1:57am  
Hello all,

I'm using OpenCV (C++) to try and process video frames.
I'm using these funcions:

int               cvGrabFrame(IplImage*)
IplImage*    cvRetrieveFrame(IplImage*)

I get a huge warning not to process the returned frame, and when trying to do so I get a bug seen only in disassembly.

I need to find a way to extract those frames into (e.g.) a matrix and reconvert them into IplImage* (which frames are).
The problem is that I can't store the frames since when grabing the next frame all previous frames are gone (even if you clone them first).

In conclusion:
I need a way to store a faw (different) frames, be able to process them and to reconvert them to IplImage* so I can present them.

Thanks a lot for your help.
