Basically, do a git clone of FFmpeg:
then if you do a "git log" it will tell you all the revisions that
have been committed, so you pick one in the middle, see if it still
has the problem, if it does pick one closer, else one farther away
from the good commit, until you can find the "1 commit" that
introduced the offending behavior.  Or do you already know which
commit did it?

So you think it fixed one problem and introduced another? which commit was it?
