how many mS delay?

It would be nice to utilise local motion detection on camera, using the hardware motion detection facilities of the chip.

If motion is detected (or stops), we could then call an external script for signalling to external systems.

As an alternative, one thought I had would be to output at a low framerate if no motion is detected, and increase to a high framerate if motion is detected. This has the benefit of being able to plug straight in to a Motion setup, while reducing CPU/GPU load on the Motion machine when no motion is detected by the camera.

Thoughts?

I succeeded in getting Makefile, but there were some errors

I just saw that you used c++11. Are you sure that's making it into your compile options? Check the generated makefile and watch the executed commands to be certain.

Can you please write compilation steps for linux? When I run ./configure it gives No package 'dbus-c++-1' found error.

Hello!
I created a build with live-streamer using a Buildroot for hi3518v200. The system starts ok (file system jffs2), but I can't start the live-streamer as before.
The command:
live-streamer -vsrc "isp0:sensor=imx222|videv0|vichn0|vpgrp0|vpchn0" -venc "vpchn0|vechn0:encoding=H264,resolution=720P,framerate=25" -stream 0:vechn0

gives the following result:

VideoSource isp0:sensor=imx222|videv0|vichn0|vpgrp0|vpchn0 not found
VideoEncoder vpchn0|vechn0:encoding=H264,resolution=720P,framerate=25 not found

What am I doing wrong?
