I am trying to capture a screen shot on the ipad while the camera is on. My code looks exactly like the AVCaptureFrames from the Xamarin MonoTouch sample:

enter image description here

For some reason, though, I keep getting an Invalid Handler Exception. I have looked at other questions similar to mine, such as:

CGBitmapContext in MonoTouch throws invalid handle exception and "Invalid Handle" Create CGBitmapContext

But their solutions aren't solving my similar problem. My issue doesn't stem from a sending in null or because my memory is too large. I'm not sending in a null value and I checked my memory usage through the xcode allocations instrument and my memory usage doesn't explode; it only adds 400KB at the most.

  • Could you please replace the image with the actual source code ? also can you edit your question to add the exact exception text/stacktrace this gets you ? thanks – poupou Dec 19 '12 at 14:43
