First, I am using IP cams
Second, vid_control_params does not have anything to do with the webserver
interface only camera fine tuning for picture/video
Normally localhost:8080 shows all cameras in a video matrix block
The autofocus function I want is when motion is detected on one of the cameras,
that camera?s video goes full screen
End of motion event, back to 8080
Playing with a bunch of ideas but still not sure what I can do after I hack
this out.
Can I publish the changes on my site?
Does the GNU allow me to do this?
Does the Original Author have to okay the changes?

There is already a config called "vid_control_params" that controls USB V4L
cameras. If your camera supports turing autofocus on/off - just use
vid_control_params

I wanted to add another Flag called Autofocus=true/false
It would ?full screen? the camera that detects motion.
A function that would seem to be a no brainer in any surveillance system.
First time dealing with GNU not sure what I can do
Thanks for any information

It sounds like you would be wise to choose a different name for your
control that didn't sound so much like a different, existing control
facility. I think you confused Tosiara for one :)

Sounds like a nice idea. What does it do if more than one camera sees
motion at the same time? (Which I expect is quite common if cameras
have overlapping fields of view)

Yes, you can make whatever changes you want on your own system.

No. They only have to approve if you want your changes to be
incorporated back into the base product.

You can achieve something similar using the
script option 'on_event_start'
to run a script that uses ffplay to display the camera
output and then stop it with 'on_event_end'.
'not elegant but it works ;o)
