Hi Prabhakar,
This looks really nice!
I'll do a full review on Friday, but in the meantime can you post the output
of 'v4l2-compliance -s' using the latest v4l2-compliance version? I've made
some commits today, so you need to do a git pull of v4l-utils.git.
I also have a small comment below:

Is this really necessary? I think vpif_buffer_init can just be removed.
Ditto for vpif_display.c.
