I have a m4v video generated by iMovie. I want to use ffmpeg to generate a widely viewable video on Windows. I cannot assume that the viewer will have VLC (or any other sophisticated viewer). It needs to be viewed by what is a default installation of Windows 7.
How do I do this? I tried ffmpeg -i video.m4v video.avi
, and that did not directly work for my users. They say they get audio, but no video.
1When you say "widely viewable video" do you mean in a codec that Windows natively supports? My understanding is that if the m4v file doesn't have DRM (which yours won't) then you can rename it to
.mp4
and it'll play happily on many platforms. – Richard – 2013-12-02T10:59:48.100
