Hi Nicolas,

Thanks for responding... I only tried the avidemux as it was suggested
in the previous post.

I do realize the difference between AVI and wmv. :)


However, I wish to use the fluwmvdec and decode/convert this file. I
am trying to learn how all this pipe stuff works,

thought I had a good example that I found, tried it and its not working.

Would greatly appreciated the correct pipeline to convert the wmv to ogv.

Thanks,


Jerry
