The OSG by default uses PixelBufferObjects for downloading video data efficiently to the GPU, all you have to do is do a osgDB::readImage(..) to get the osg::ImageStream that you than assign to a osg::Texture2D/TextureRectangle and then the OSG will do the rest for you, you will not need to worry about making things efficient, by default it'll be as efficient as you can make it ;-) See the osgmovie example for how to set things up.
