The fact that it's within ffmpeg is meaningless; by using
--enable-gpl, ffmpeg is now GPL, and you're using a GPL application
within your program.
However, it is often considered okay, because you're calling
ffmpeg.exe as a separate program, not linking to it, so the provisions
of the GPL may not apply. I think this is okay, but I'm not a lawyer,
so if you're worried about that, I suggest talking to one.
