at first many congrats for the new vvvversion and the new site.!!!

but what i want to know:
you recommended eyesweb for image recognition purposes. my aim is doing some kind of blob analysis in eweb using a webcam as image input. the communication between eweb and vvvv via osc works fine, but what if i also need the webcam image in vvvv as video texture? for the fact that its not possible to get signals from the webcam in both applications, is there another way to solve that problem?

thx and best regards,


If you run eyesweb and VVVV on seperate machines (what most of the time is the way to go, because eyesweb eats a lot of CPU-performance) you could use simple cheap analog framegrabber cards with a Bt848 / Bt849 / Bt878 & Bt879 Chipset in both machines and a normal videocamera.
With this setup you can simply feed the videosignal into both systems without having to worry about software at all.
Other advantages of this solution are that you do not have to worry about long usb-cableruns, you are very flexible in choosing the right camera and cameralens for your project/installation and usually the framegrabbercards are much faster than webcams or firewire-cameras.

For best performance (especially in eyesweb) I made very good experiences using the universal Bt848 / Bt849 / Bt878 & Bt879 driver available at http://btwincap.sourceforge.net/ instead of the original driver supplied with the card.

good answer!

for this topic (vvvv & EyesWeb) was createt a new HowTo page. Please continue your discussion there! Many thanks!
