Posted - Jun 09 2015 : 02:45:37 Hi, I'm showing a preview of a webcam using DirectShow, inside a TImageEnView control.
I need to show only a portion of the image (a rectangle) What's the best efficient way to do this? Doing this in DShowNewFrame event is expensive in resource usage (as is done for every frame)
Any suggestion?
Thanks Claudio Basso

Posted - Jun 10 2015 : 00:28:04 What component do you suggest? I'm using a Logitech WebCam PRO C920 The video preview must show an image that can be cropped, rotated and zoomed. Now I am applying these settings on the DShowNewFrame event. Can another component apply these settings directly on the source?

If you need realtime video display, I think it would be too inefficient to do this with ImageEn/DirectShow
