I get a small error when i try to convert my .webm files into mp3 using ffmpeg ...

It say premission is denied ...

See my screenshot ...





I run acidrip and avidemux with out any issue's so what can be wrong ...

I run Ubuntu 12.10 ...

This is for my daughters computer, so i can teach her how to use winff and youtube to get her own mp3 files and put them into her mobile phone ...
