So far, I'm just letting it be a driver-specific extension. I haven't looked at the extensions in detail yet. On their system, they're mainly just using V4L2 ioctls (plus extensions) to route the video streams around the hardware in the box. No read(), no mmap(), no select(). I am not, in principle, against incorporating STB overlay-type functions into the API, but these devices tend to each have unique architectures and internal routing and display-combining options. Hard to standardize. Bill.
