[Help] wmv to flv with ffmpeg

[Nightslk]

I am trying to convert flv to wmv, and avi to wmv with ffmpeg is not working, always appears this error:

ffmpeg -i video.wmv -ab 128 -ar 88100 -b 800 -r 25 -qscale 5 -s 480x360 -f flv video.flv

Unknown input or output format: wmv

Someone could give me a hand and tell me why is not working here, I'm using the ffmpeg version 0.5.

I can tell what's wrong with the command line but your source seems to have no audio and a uncommon frame rate so it's still dubious if it will work.

ffmpeg -i video.wmv -ab 128k -ar 44100 -b 800k -r 25 -qscale 5 -s 480x360 -f flv -y video.flv

You need to add a "k" to the given bitrates and -ar 88100 sample frequency is not valid (make it 44100).

Thank you, but now it convert the wmv, but gives an error message saying that can not encode audio, but I think it will work right here.

Thanks for the help friend ...
