It's better to run the command and next look at $? for the return status.
Success status is zero, so "if zero" won't execute the "then" clause, which
I assume is what you want (run ccextractor if ffmpeg succeeds).
What is $lock used for?
Construct the filenames first into vars, then use those in a command.
(I really dislike bash scripts, btw.)
Doesn't look like any of this is related to ffmpeg, though.
