You can use ffmpeg crop filter to "cut" part of the video and save it to a file. The following example saves the bottom right quarter of the input image (taken from the link):

ffmpeg -i input.avi -vf crop=in_w/2:in_h/2:in_w/2:in_h/2 output.avi

See doc/examples/filtering.c for an example of how to do it in C.
