after a lot of reading i think i know how to do this, but thought i'd check in here first before buying parts since it's my first time trying it.
i want to set up a streaming webcam. high framerate is more important than resolution or video quality. the webcam does need to be a composite video source, rather than using a USB or firewire webcam, so capture is part of the project.
i've been trying to use the vloopback module to get video4linux applications like xawtv, kdetv, webcam, etc. to recognize it, but haven't had much luck. i install and modprobe the module, i get a /dev/video0 and /dev/video1 device, but kdetv (for instance) complains that it can't capture from videoloopback 0.
so: my guess is that firewire is not the way to go, and i should get a capture card. looking at video4linux resources, it looks like i should get the hauppauge winTV 250 or 350 .. ?
then, my theory is to either (a) continue the same approach, of saving jpegs, just smaller and faster ones now... or (b) to use vlc as a streaming server. if i do that, is it possible to make the stream viewable in a plugin in a webpage, not just in the vlc client? preferably in a way that would let people using mac and windows see it too
