Problem converting frame to IplImage

[saudet]

FFmpegFrameGrabber owns the Frame. You'll need to call stop() after calling convert().

And after calling cvShowImage().

Thank you for the specific answers. But I still can't get frames converted to IplImages. Here is some new code that focuses on the specific problem... I have two int control variables: doBuf and doIpl. They control whether I want to extract a video frame into a BufferedImage or an IplImage. If I set doBuf= 1; and doIpl = 0; then the code runs and correctly displays a very large full color image from the video frame. However, if I set doBuf= 0; and doIpl = 1; then the code runs but erroneously displays a fairly small monotone dark gray image that has no relation to the video. The two sections of code are NOT identical. But they are as similar as I can make them. I have no idea why one works and the other doesn't. Is there some easy fix that I'm overlooking, or do I have to use BufferedImages and give up on IplImages?

Like I said, you'll need to move stop() and close() after cvShowImage() for this to work. It could also work if you clone() the image, but still again always before calling stop() and close().

I don't know whether to say Eureka, Hallelujah, or simply Thank You. My problem was that when you said the position of close() was essential, I didn't realize you were referring to converter.close(). I understand now.
