Hi, i was wondering if there is a way to capture images from a webcam with juce?
I have some Mac code that works with Juce, but it’s very early stages…
Suport for capture devices is very platform specific.
In Windows i don’t think there is another way then using DirectShow.
So Juce would be dependant of DirectShow, and i don’t think that Jules wants this.
I found a simple and easy library that works fine for us.
You don’t even have to install the DirectX Sdk, you can link directy to this library.
wow, this is just what I was looking for, much appreciated. Do you have any sample code to show juce integration, are u able to show the video stream inside the juce app? How do u convert the captured frames to juce image format?(Is it fast?) Cheers gekkie100!
i had no problems at all getting it to run in a Juce based app.
You can get a pointer to the pixels of a newly captured frame and just copy it directly into a Juce Image.
Something along these lines, capturedPixels would be the pointer to the captured frame.
Image frameImage(Image::RGB, captureWidth, captureHeight, false); uint8* framePixelData; int lineStride, pixelStride; framePixelData = frameImage.lockPixelDataReadWrite(0, 0, frameImage.getWidth(), frameImage.getHeight(), lineStride, pixelStride); memcpy(framePixelData, capturedPixels, width*height*3); framePixelData = 0;
works nicely, thanks again!
