v4l2

Hi,

I use the v4l2 api for video capture and image applying image processing algo' on each frame.

I wish to be able to suspend the video capture. I see that there are 2 options for ioctling (new verb, its gonna catch) the stream. VIDIOC_STREAMON, VIDIOC_STREAMOFF will start and stop the stream.

Is there a way to suspend \ resume it? Is this even necessary, or can I just use the start and stop controls with no extra processing time spent on creating the stream all over again ?

Thank you for your time,

Itamar
