Am I correct that the following command line is sufficient 
to trigger the OOM?
$ ffmpeg -f video4linux2 -r 2 -s 1280x720 -i /dev/video0
(What about different values for -r ?)

If yes, you could add a few av_logs to find out where 
exactly it goes OOM but I would expect the problem is 
not FFmpeg-related.

Please do not top-post here, it is considered rude,
