I am trying to transcode an m4v file from iTunes so I can play it on Windows or XBox. I am running ffmpeg from Windows. Is there some -vcodec I need to specify or something I need to install? Here's the command I'm running and the error I'm getting.

Where did this video come from? The 'drmi' and 'drms' codec tags make me think if might be encrypted / DRM-protected. – Multimedia Mike – 2014-02-08T17:54:57.427
Ah. Makes sense. Came from my Apple TV. I wanted it on my XBox too. Is there a practical way to decrypt it? – None – 2014-02-08T22:37:47.027
