How to convert wmv to mp4?
Suggest ffmpeg tweaks for converting from WMV to FLV?
I've installed ffmpeg
through MacPorts using the following Terminal command:
$ sudo port install ffmpeg
After this is done I can use ffmpeg to convert videos, which works well for the non-WMV video files I've tried:
$ ffmpeg file1.mov file2.mpg
However, when I try the same command with a WMV file, I get an error:
$ ffmpeg file1.mov file2.mpg

WindowsMedia.wmv: Unknown format
This leads me to think that there must be some missing codec in the Mac port of ffmpeg or some option I've neglected to enable. I must admit that I am not an ffmpeg guru and really I don't know what prevents me from converting the WMV file this way. From what I've read the ffmpeg project is supposed to support WMV files.
Any help is appreciated.
Thanks!
