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
  libavutil     49.15. 0 / 49.15. 0
  libavcodec    52.20. 0 / 52.20. 0
  libavformat   52.31. 0 / 52.31. 0
  libavdevice   52. 1. 0 / 52. 1. 0
  libavfilter    1. 4. 0 /  1. 4. 0
  libswscale     1. 7. 1 /  1. 7. 1
  libpostproc   51. 2. 0 / 51. 2. 0
  built on Jan 15 2010 13:26:39, gcc: 4.2.1 (Apple Inc. build 5646)
  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!

I'm running 10.6.2 with the exact ffmpeg (installed using MacPorts) and I can convert wmv to mpg using ffmpeg -i file1.wmv file2.mpg. My complete output for a random WMV file I found on my Boot Camp partition is at pastebin but here's the main part:

Input #0, asf, from 'SportsMainBackground.wmv':
  Duration: 00:00:13.97, start: 3.065000, bitrate: 3135 kb/s
    Stream #0.0: Audio: wmav2, 44100 Hz, stereo, s16, 48 kb/s
    Stream #0.1: Video: wmv3, yuv420p, 720x480, 8000 kb/s, PAR 6:5 DAR 9:5, 29.97 tbr, 1k tbn, 1k tbc
File 'test.mpg' already exists. Overwrite ? [y/N] y
Output #0, mpeg, to 'test.mpg':
    Stream #0.0: Video: mpeg1video, yuv420p, 720x480 [PAR 6:5 DAR 9:5], q=2-31, 200 kb/s, 90k tbn, 29.97 tbc
    Stream #0.1: Audio: mp2, 44100 Hz, stereo, s16, 64 kb/s
Stream mapping:
  Stream #0.1 -> #0.0
  Stream #0.0 -> #0.1

EDIT
Just thought of something. What is the output of ffmpeg -formats | grep wmv? On my system, I get:

 DEVSD  wmv1            Windows Media Video 7
 DEVSD  wmv2            Windows Media Video 8
 D V    wmv3            Windows Media Video 9
