Ok thank you you've found the clue.
I've got now a nice pix_gst2pix function working inside a beautiful pdgst library compiled against a great Gem 0.93.3 inside a fantastic PD 0.42.5...
it's seems easy but it's days racking my brains... see, you buy a mac saying you won't need to understand command lines and programming and finally you can't deal with the first unusual use of your computer, lazy man I was (am ?) ;)
great, now I reach the center of my desires :
how can I manage to display a live webcam (not mine, e.g. a random one) only knowing its url ? is it just possible ?
do I need to use e.g. VLC to get it, what about an icecast server ? I don't know much about that domain though, that's why my hopes where in that pdgst library to modify webcams with gem...
thank you again Iohannes for your support on getting this thing to work anyway !

I'm still having doubts about having installed PDGST propertly. When I open all of your tests patches pd can create all pdgst objects except dv1394src (linux ?), audio/x-raw and of course the one I would need : pix_gst2pix (and the reciprocal function).
