title: Is it possible to use FFMPEG to generate F4V videos?
body: <p>I need to generate a script that converts videos to F4V's for use with Flash Media Server 4.5...is this possible?  I have it converting files to MP4s and then swapping the extension. This works fine, but seems like a dirty work around.  I'd prefer to use a generate a true F4V. I've heard mixed things on whether or not ffmpeg truly supports F4Vs.  Any guidance would be appreciated.  Also, is there a doc guide on what file formats are allowed by FFMPEG?</p>
