Its not a dispute its just constructive argument, everyone is entitled to license how they like, Jonah thanks for showing its possible to do multicam in CCV.

how is your hardware handling 4 or 8 USB cameras?

we’re getting some bottle necks somewhere with 4 on our system, but we’re not using CCV.

or is real-time tracking not a concern for your application?

I don’t know what you mean, I didn’t use USB cameras for multicam project.

well, that’s one way to solve the problem

Great Job!

thanks for reply, We have modified the source code. As we know ,there are a lot of bugs in tbeta, we have spent much time and energy on this.Next I will use one computer to control 8-cams.

Looks like nice work. If there are bugs in ‘tbeta’, would it be possible to get a list so we can fix them?

Hello all,
I try to use PS3Eye with DirectShow.
And now it run.
But I can’t set the resolution. It always 640*480.
Can any one help me ?
My C++ DirectShow code here:

VIDEO_STREAM_CONFIG_CAPS caps;
pSC->GetNumberOfCapabilities(&iCount, &iSize);
// default capture: 320 * 240 resolution, 30f/s
VidFormat vit={ 320, 240 , 30};

for (ind = 0; ind < iCount; ind++) {
pSC->GetStreamCaps(ind, &pmt, (BYTE *)&caps);
if (caps.InputSize.cx == vit.width && caps.InputSize.cy == vit.height) {
// Set the capturing frame rate
VIDEOINFOHEADER *pvi = (VIDEOINFOHEADER *)pmt->pbFormat;
pvi->AvgTimePerFrame = (LONGLONG)(10000000 / vit.framerate);
JIF(pSC->SetFormat(pmt));
DeleteMediaType(pmt);
break; // found default setup, quit the loop
}

DeleteMediaType(pmt);

}

Thanks

Hello all,
I’ve use Directshow to capture multi cameras (4 cameras). And It runs good.
Next things to do is mapping each frame to rectangle.
Then merge them into a frame. Then process this frame like use 1 camera.

4 cameras (320*240) ==>> 1 camera (640*480)

GOOD JOB, I will develop multi cameras in the futrue, too!

Interesting thread guys Nice work with multi-cam in CCV too by the way!

After two months of efforts, we have made it.

Ohhh jonah great work! really looking forward to seeing a quick video

mmmmm, ripples in hands only to the left side..........; non bloobs in ccv................ mmmmmmmmmm ............ suspect!

Pretty interesting job Jonah, as Christian said, we would love to see a video of it. Sad to hear we are not going to see the code you modified though.

One thing, please, at least let the community know which bugs have you found so they can be solved on future releases.
