Hi,
I am trying to use the quicktime plugin with osgmovie to stream from a webcam.
My video files (.avi) are working fine but using live streams renders a blank
quad. Like what is mentioned in related posts, I have installed WinVDIG 101 and
quicktime 6.5 on a Windows Vista 64 bit machine. When queried with "--devices",
one webcam is detected and I get the following errors. Looks like a quicktime -
WinVDIG communication issue. Any help would be highly appreciated.
VDGetPreferredImageDimensions(aComponent, &pref_width, &pref_height) - ERROR
VDGetInputName(aComponent,(long)i, name) - ERROR
...
The whole of it found below.
