ffmpeg is not working on ubuntu 9.10

Hello,
I have been trying to convert a flv file to mp3 for over a week now using ffmpeg, but until now I could not get it to work

here is how the command runs

Code:

I thought it would be the lame codec but I made sure that it was installed

I have mplayer, w32codecs, vlc player, dragon player and some conversion software that I downloaded from syanptic

What can I do to make ffmpeg convert my files again?

Thank you.

PS: mplayer is not working well and usually displays errors so vlc is my default player.

Code:

mplayer -dumpaudio Kassas\ Season\ 2\ -\ Episode\ 10.flv && mv stream.dump kassas_10.mp3

or

Code:

ffmpeg -i Kassas\ Season\ 2\ -\ Episode\ 10.flv -f mp3 -vn -acodec copy kassas_10.mp3

Thank you ciotog,
I tried the ffmpeg command and it worked, but only out of curiosity why did the simple ffmpeg -i command did not work?

It used to work before on 9.04

It would appear to me that originally "mp3" was the default output audio type, but this was changed to 0x0 which doesn't appear to be anything in particular. Or perhaps before ffmpeg used to use the same codec as the input file, but now requires you to specify the output format.

It might be that ffmpeg was altered, or it was packaged differently by the Ubuntu package maintainer. Hard for me to say, as I'm not really involved with either

AGazzaz · 11-15-2009, 12:44 PM

what shall I change in the command if I want to convert a rm file?
