What happens if you open a command prompt and manually type this at the prompt:
c:\ffmpeg.exe -i c:\test.mov -b 40k -r 10 -s qcif -target pal-vcd c:\test.3gp
Do you get the same error message? If yes, then '-i ...' is probably not a valid option for ffmpeg. Do you have documentation for ffmpeg? Does it say something about the '-i' option?
Can you show us the Java code that you use to execute ffmpeg?

If I launch this
from the command line it works
cmd.exe start /c c:\\ffmpeg.exe -i c:\\Surf\\text.mp4 -b 40k -r 10 -s qcif -target pal-vcd c:\\Surf\\mov.3gp & exit
If I launch it from a simple java class it works.
But if I launch it from a javaBean called from a
it doesn't work. It never exits from the execution of the command...
