I would like to set up a video double-buffer implementation with COGL (perhaps using offscreen buffers?) to render to a Clutter texture. It would be great if I could do something along the lines of passing a reference to one buffer's backing memory to an application to fill with video data, and then when the data has been written, swap in the buffer and request the texture to be redrawn. If another approach would be better, that would be fine too. A simple example would be very illustrative for a broad class of problems I would like to solve.
Thanks very much for any help. Brian McGann
