Currently obmc-ikvm gets a steady stream of JPG images, frame by
frame, from V4L2. Have you considered extending it a bit so that it
would be capable of simply saving the current frame to disk, without
any conversion/transformation, just dump an array of bytes to a file?
What would be the advantage of establishing a local VNC session with
this additional software compared to the straightforward JPG to file
writing?
