Luckily I do not need audio. Just video.

My need is that I have to separate the images into files when some event
occurs. Or, that was going to be my approach. Perhaps I could just break
them by time and use the GOP marker to determine exactly which frame the
break will occur in. Then I just record the file and offset to the most
recently seen GOP when the event occurs. How CPU intensive is it to
locate buffers that have a GOP header?
