Bug#495274: ffmpeg (arm) stops with the error message "Could not read stream parameters"

Hi Martin !
I have seen ffmpeg working on my slug in an early version of etch and also
on my ubuntu based laptop (syntax exactly like in the bug report)
# ffmpeg -r 30 -s cif -f video4linux2 -i /dev/video0 http://localhost:8090/feed.ffm
/* ffmpeg tries to read the stream parameters from http://localhost... !
/* don't forget to start ffserver before !
/* The video source (webcam) is read from /dev/video0 and should be streamed according to the stream parameters
see here: ( it seems like the syntax for ffmpeg changed a bit, but i
tried several possibilities without success )
section: PWC: The Debian NSLU2 method
Currently I am out of time to compile the ffmpeg package myself.
Could you please try to check the syntax/reproduce the error ?
