Dear all:
I have a question for croping a subimage of the source
video and scaling to some size(ex: 640x480). I have tried the example of V4L2
but still can't work. By the way, the process I use cropping I/O control
is the following:
open device -> set video format -> set norm -> set
input -> mmap -> streamon -> cropping function(VIDIOC_S_CROP)
Does anybody can help me?
