Hi,

I'm working with a v4l2 camera and want to implement some processes 
using gstreamer.
I'm using the v4l2src element to get my images and was wondering if 
there is a way to set the crop area or any plan to implement it.
Using the videocrop element is not an option. I need to set the crop 
area of video4linux in order to get higher framerate from the camera.

Moreover I have had a hard time trying to find information about the 
"extra-controls" property.
What it is exactly and how to use it?

Best Regards
