[Ffmpeg-php-user] problem avi -> 3gp

[Nicolas G. <ni...@di...>]

Hello,
 
I try to convert .avi or .mov movie into .3gp in order to see it on
phone.
But, I have this  error :
 
./ffmpeg -i blabla.mov -s qcif -r 12 -ac 1 -ar 8000 -b 30 -ab 12
blabla.3gp
 
 
ffmpeg version CVS [.........]
Input [.........]
Output #0, 3gp, to '/blabla.3gp': 
  Stream #0.0 -> Video: h263, yuv420p, 176x144, 12.00 fps, q=2-31, 30
kb/s
  Stream #0.1 -> Audio: 0x0000x 8000 Hz, mono, 12 kb/s
Stream mapping:
  Stream #0.0 -> #0.0
  Stream #0.1 -> #0.1
[h263 @ 0x832948c]removing common factors from framerate

If somebody could help me.
 
Thanks.
