Re: v4l2 vs omx for camera

In the reference architecture in ppt, we can directly wait for the RSZ interrupt, if we configure the hardware pipe. It was my mis-understanding as each of those hardware blocks can deliver interrupts too. In that way ARM needs to just work at finished frame, like forward it to the display or codec engine etc. V4L2 can be easily used for such hardware architecture.

But if a ISP chooses to do the above work in a seperate (dsp)processor, can we still use V4L2? OMX seems better in such environment. Let me know if there is any other alternative.
