[MEncoder-users] convert audio file to flv

[周国强]

It's simple to convert an audio file to flv via ffmpeg:
ffmpeg -i input.mp3  -acodec libmp3lame  -f flv  -ac 1 -ar 44100  -ab
64k  -y out.flv

I try to use mencoder to convert the audio:
mencoder input.mp3 -oac mp3lame -ovc raw -vf noformat -o out.flv

But it tells me "Video stream is mandatory".

Thanks for the answers.
