<br>
I'm using camerabin to grab stills from a webcam showing a video stream.<br>
I've set the image-capture-width and height properties to give a larger<br>
image than the video stream size, however they're being ignored and the<br>
jpegs being created (from the capture-start signal) are the same size as the<br>
video.<br>
<br>
Am I missing something I need to do to get different sized images? The size<br>
I'm requesting is supported by the webcam...<br>
<br>
Thanks!<br>
Justin<br>
