We understand the motivation behind making the daemon optional.
However there are restrictions from legal perspective, which we
don't know how to get around.

A simplest video streaming data flow with MSM ISP is like this:

Sensor -> ISP Hardware pipeline -> videobuf

The procedure to set up ISP pipeline is proprietary and cannot
be open sourced. Without proper pipeline configuration, streaming
won't work. And That's why we require the daemon. 
 
Thank,
Shuzhen
