ffmpeg wmv to flv?

[eluser]eoinmcg[/eluser]
A shot in the dark but does your server have all the necessary codecs (i.e. for wmv) installed?

You can tell ffmpeg which codec to use

Code:

exec('ffmpeg -i '.$uploadfile.' -f flv -s 320x240 -vcodec wmv1 -acodec adpcm_ima_wav '.$new_flv.'');

Also try generating a log file to see any errors...

Code:

exec('ffmpeg -i '.$uploadfile.' -f flv -s 320x240 -pass 1 -passlogfile log-file '.$new_flv.'');

Hope this is of some help!
