[FFmpeg-user] streaming ip camera

hi there, i've got an ip camera on my local net and want to build a live stream of its pictures. the camera provides the current picture under http://<ip>/jpg/image.jpg i wrote a bash skript that sends the camera pictures to ffserver: while true; do ffmpeg -an -i http://192.168.0.201/jpg/image.jpg http://localhost:8090/feed1.ffm; done; when i access http://localhost:8090/test1.mpg with ffplay i see a freeze image, but only if i'm lucky... most times nothing happens... why doesn't ffserver buffer the cam pics? i would be happy if someone helps me. franz
