Thank you for advice.
Concerning the webcam, I'm pretty sure that the raw video stream is already
*compressed* (USB 1.1 can't handle high datarates), but I'm not sure that it
can be handled by VLC without transcoding.. The webcam driver already
perform some transcoding -> that will eat CPU.
I'll look forward for USB Video Class compliant webcams.


I'm not feeling comfortable with VLC, but any advices are welcomes !

Any ideas ?
