I have Axis IP cam which produces mjpeg, from my pc i grab the wideo with wget into fifo, encoding it and cutting in parts with ffmpeg. Using parts of the video in pd. It works. problem comes when you need uninterrupted stream. Emptying buffer crashes installation. There are IP cams that produce mpeg4, 3gp (Vivotek), mp4, or other formats, but you would have to receive stream in pd and stream it from there again i guess.

ola,
let's see, does your ip cam delivers you a stream in the form of http://ip:port/something.someformat ?? where someformat = mp4, mpg, ogg ?
in that case, you can use that solution :
in a shell script :
rm /tmp/pipe
mknod /tmp/pipe p
mencoder -nosound -ovc raw -of rawvideo -vf format=rgb24,crop=320:240
http://ip:port/something.someformat -o /tmp/pipe
in pd :
pdp_rawin /tmp/pipe bitmap/rgb/320x240
suerte, sevy
