[FFmpeg-user] Subtitle filter and filename with quotes and spaces

[Ramit Bhalla]

Thanks James, you're a genius. It worked! I was really losing my mind
trying to figure this one out.

You're right, it's kinda stupid but that what it is, you need to escape the
\ : and ' and the those slashes need to be reescaped!

I wonder if there's are any other special characters that ffmpeg requires
to be escaped apart from \ : and '
