anybody have working video capture on a pc and windows 7?

in Integration and Hardware • 2 years ago

Just wondering if anybody has had luck capturing video on windows 7. I'm having trouble with my webcam, and would be willing to invest in a new camera (or a kinect?) if i knew that there was some hardware setup that is working for people.

My current (not working) setup is:

windows 7 x64.

winvdig 1.1

quicktime 7.6.9

processing 1.2.1

logitech communicate stx

thanks!

i dont see a good reason why it shouldnt work.
Whats the problem? Some error messages in processing? Does your webcam work in other programs?

You're right - i didn't provide enough details! Where it seems to be dying for me is in winvdig. When I run the test app "QTCap" it spits out an error:

"0Logitech QuickCam Communicate STX-WDM : Problem connecting Video Output to Video Renderer"

I get the same error running the examples through processing. I scoured the internet for other vdig programs but the other ones that come up as recommended no longer exist (i.e. abstract planes vdig)

The webcam itself seems to work fine, I can skype with it and capture video through openframeworks, so it seems pretty isolated. I also tried a different webcam last night and got the same error message "0Logitech Orbit/Sphere: Problem connecting Video Output to Video Renderer". Though to be fair that webcam might be using the same logitech drivers.

Oh - and i should add i've done the winvdig 1.01 uninstall, reinstall, quicktime uninstall reinstall, dance a few times to no avail.

Thanks!

Can somebody help me ?
Thank you.

What you can try is use VirtualDub to capture. There is also an option in it, that lets you export directly in an other program. http://www.virtualdub.org/

thanks dariusgeo - that totally worked! But as you suggested - i had to follow the installation instructions *exactly*. Superb.

Now i just need to figure out how to convert the video feed into a opengl compatible texture. I feel like that may be a much taller order than i was originally anticipating though...

EDIT: maybe not so bad after all. opencv.pixels() seems to be plenty fast:

videoTex.putBuffer(opencv.pixels(opencv.BUFFER));

gets my video into opengl quite nicely.
