How does one know in the user space which part of the video buffer contains jpeg data and which part is yuv? Does the data contain some kind of header, or how is this done currently? I'd be much in favour or using a separate channel ID as Guennadi asked; that way you could quite probably save one memory copy as well. But if the hardware already exists and behaves badly there's usually not much you can do about it.
