I looked at it and I am not too clear what advantages it offers us over 
subtree. One advantage I see is it keeps commits to the main code 
separate from those to the subrepo, thereby making it easier to send 
back upstream changes. However we do not have the ability to push 
changes back to FFmpeg. I think the developers may be reluctant to use a 
third-party component like this unless there are very clear advantages.

These have been in place for a long time and developers who originally 
created them have submitted them to FFmpeg a long time ago but they were 
never accepted.
