Changing video capture size during runtime (Read 824 times)

Changing video capture size during runtime
Aug 22nd, 2005, 9:26pm  
I need to change the video size during runtime. When I set capture.width and capture.height parameters, video image gets weird and if I call Capture constructor during runtime
(camr = new Capture(this, cam, camWidth, camHeight, camFrameRate)Wink I get an error message (couldntGetRequiredComponent) and my applet crashes.

Is that impossible, or am I doing something wrong?

Do you need to change the actual amount of information being captured during runtime? Could you not to set it for maximum condition and then copy / scale it to a buffer as required?

The obvious being:

image(captureName, x, y, xsize, ysize);

I think trying to modify during runtime is a no no, could be wrong though!

But I'd guess that you'd need to somehow dispose of the current capture object before you could instantiate a new one at the very least, hence the error.
