[Linux-Biella] convertire file .flv in .mpg o.avi

[Emanuele Scopel]

Alura dovrei convertire i seguenti file, io uso ffmpeg con questo comando:
# ffmpeg -i /home/emanuele/beryl1.flv -ab 56 -ar 22050 -b 500 -s 
320x240   /home/emanuele/beryl1.mpg
ma il cornuto mi ritorna: 

emanuele a emanuele-desktop:~$ 
ffmpeg -i /home/emanuele/beryl1.flv /home/emanuele/beryl1.mpg

Seems stream 0 codec frame rate differs from container frame rate: 1000.00 
(1000/1) -> 25.00 (25/1)
Input #0, flv, from '/home/emanuele/beryl1.flv':
  Duration: 00:04:03.8, start: 0.000000, bitrate: N/A
  Stream #0.0: Video: flv, yuv420p, 320x240, 25.00 fps(r)
  Stream #0.1: Audio: 0x0000
File '/home/emanuele/beryl1.mpg' already exists. Overwrite ? [y/N] y
Output #0, mpeg, to '/home/emanuele/beryl1.mpg':
  Stream #0.0: Video: mpeg1video, yuv420p, 320x240, q=2-31, 200 kb/s, 25.00 
fps(c)
  Stream #0.1: Audio: mp2, 64 kb/s
Stream mapping:
  Stream #0.0 -> #0.0
  Stream #0.1 -> #0.1
[mp2 @ 0xb7e8aac8]Sampling rate 0 is not allowed in mp2
Error while opening codec for output stream #0.1 - maybe incorrect parameters 
such as bit_rate, rate, width or height

Ho googlato ma non ho trovato soluzione. Premetto che non conosco pochissimo 
ffmpeg.

Ciao
