Hi there,
I am trying to get a webcam-feed from a site onto a dx9-renderer. And, if possible, from a lot of different webcams… therefore it doesn´t simply work with html-renderer.
Well I allready consulted the forums, and since I am a beginner I am kind of overwhelmed by everything.
What I tried to do, is taking a “html-get” node --> “dynamic texture” --> quad and renderer. but it doesn´t show anything on my quad.
Anybody can please give me a hint?
Thanks a lot
I think what your are trying to do can not be done with VVVV right now. One would need some kind of “videostreaming-client-node” which doesn´t exist up to now.
The HTTP Get node isn´t capable of fetching videostreams.

ah. okay. haha. would have been too nice. thanks anyways for your answer.

hi…
I am also interesing in this field…
so there is no possibilty in the moment to capture a cam in realtime mode and manipulate it in vvvv?
is there no way to replace a texture by a realtime recorded video??? would be very sad, because this would change my whole masterwork…
I am building in the moment a infraredsensor for midi data which should finally try to manipulate the realtime video input.
@Acidnoid:
Of course you can use VideoIn (DShow9) for your connected cams .
here the point is fetching a webcam stream from the internet.
wow, thanx…
I´ am totally new to vvvv… working with it since one week…
but I will keep you updated here with my project…
its a master thesis and i am working on a little amchien.
if somebody is interested how to build a infrared sensor, i found this nice page:

very very useful
Ha!
Workaround for the webcam feed mentioned above:
get Camtasia Studio from http://www.techsmith.com
Camtasia Recorder allows streaming.
open your favourite webpage with camera livestream.
start camtasia recorder
settings:
now Camtasia Studio Video Capture Driver should show up as a device on the Driver-pin of your VideoIn (DShow9) node.
i built something similar with v4: works, but not too good: html-render --> gdi texture --> quad(with transforms) --> dx9render --> dx9 texture --> writer.
so far for one webcam-feed it works. but what i tried to do is to display various webcam-feeds (from various locations) on one renderer. and that s not possible with the method mentioned above (since you are always recording parts of the computer desktop too). hmmm…

WebcamCapture.v4p (5.2 kB)
news from the webcam front: i dont know if this is commonly known, but a lot of webcams are not streamed, but resolved in mjpeg, which is basically one jpeg after the other (correct me, if i m wrong). knowing that, it s possible fetching webcam “streams” via vvvv. YEAH!
BUT: i tried to use the html-get node doing this. it works, but i ve got problems with the reloading speed (as it would be on a regular webpage, where it looks like a movie). any ideas out there?
webcam_fetch.v4p (10.4 kB)
the problem is that you are trying to reload the image without knowing / checking if it has finished loading yet. So if it hasn´t finished, the attempt to load it will be stopped and restarted when you trigger the refresh pin.

ahhhh. very nice. it vvorks great. thanx a lot pal!
anybody got an idea why those fetched images are so low in resolution. i allready adapted backbuffer width and hight to the size the (online) image has…

i got the same question.
since this is an old post and as far as i can tell in the new version of vvvv. html renderer doesnt excist anymore.
is there a solution/workaround/node that can do this?
thanx

bjoern’s patch still works, no html renderer involved
