When I use media-ctl the pipeline gets configured properly. I can 
generate graphs before and after and see the pipeline change. However, 
my system hangs when I attempt to use yavta. I've also tried outputting 
to video4.

Does anybody know how I can capture images from the camera? From 
previous posts it appears that I'm not the first to go through this process.
