---help---
DO NOT ENABLE THIS OPTION UNLESS YOU KNOW WHAT YOU'RE DOING.
This option enables the Request API for the Media controller and V4L2
interfaces. It is currently needed by a few stateless codec drivers.
There is currently no intention to provide API or ABI stability for
this new API as of yet.

# Video4Linux support
