[Ffmpeg-user] how do i convert wmv3 codec?

[tamal]

Hi All,

I'm using following command to convert a wmv file to mp4. This wmv file is in wmv3 format. Does ffmpeg support wmv3? i did rebuild ffmpeg from cvs but wmv3 simply not working. Do I need to do anything else to allow to convert wmv3 to mp4/flv?

Any help will be highly appreciated.

Thanks.

You can either use MEncoder and binary codecs to convert the WMV3 or
follow the tedious instructions on this page to get FFmpeg to understand
WMV3:
