Edit M4V Video Metadata

So far my google-fu has failed me, so I'm hoping someone here can help:

How can I programmatically modify video metadata (specifically in my case, m4v video files)?

I'm most familiar with Ruby and C#, but I can be fairly language agnostic on this -- that is, if there's a specific language that is good at开发者_如何学运维 modifying file metadata, I have no problems spending the required time to learn it well enough to accomplish what I'm trying to do.

This question is pretty similar to:

View/edit ID3 data for MP3 files

I have searched for the library so you dont have to:

Even tho it has linux on its name it is for mono, so it should compile fine in Visual Studio :)

Hope it helps.

Consider asking http://www.ffmpeg.org/contact.html in #ffmpeg

I don't think they use ID3 tags.
