Hi,
I am currently looking into the vcsm lib to display buffers with minimal copy overhead. I tried to combine VCSM buffers with Dispmanx without luck. Now I am wondering, if this is even possible. And if so, how?
Using the mailbox is not an option due to its limitations (requires full access to /dev/mem). MMAL seem to have a lot of overhead for such a simple task.
What I am basically looking for is the hello_dispmanx example without the "vc_dispmanx_resource_write_data" call (vars->image already a VC buffer).
