[Ssc-dev] obscuracam update

[Nathan of Guardian]

Still debugging memory leaks on ffmpeg. This is the source of the videos
that are unable to be played. After a certain amount of time, some files
will cause ffmpeg to leak memory and crash, creating the corrupt video
files. I've gotten the latest ffmpeg code building, but the problem
persists.

We are tracking/discussing the issue here:
