Hi guys,
I installed ffmpeg on mac os x a couple weeks ago, and it was working
great, then about a week ago, for no apparent reason, it began spitting out
mp4's with no video, but with the correct duration and audio intact. I have
since then tried multiple scripts in terminal, reinstalled ffmpeg, and even
installed it on another machine to have the same results.
I know this is probably a user-error but I would really like to get this
resolved! This is the most recent script in terminal that failed.
