Hi Anthony, It does sound like you might be over-complicating things. The OSG natively supports copying image data to textures using PixelBufferObject, all you need to do is assign an osg::PixelBufferObject to an osg::Image, then assign this osg::Image to the texture you want, and the OSG will do the rest for you. The osg::ImageStream class which subclasses from osg::Image by defaults assigns a PBO, so all the video related plugins will automatically use PBO for copy data from main member to the GPU.
