Hello community.
Who I am? An idiot trying to do things too complicated when I am sure
there is an easier way. I do have linux/raspberry/bash/python
experience but I am no expert on any of them.
What do I have? Raspberry Pi Zero WH, Raspbian 10 Buster, Raspberry
Camera 2.1, Raspberry HDMI Touchscreen (USB connected, not GPIO), Of
course SD and all appropriated cables.
What do I want to do? I want to activate the screen when motion
detects movement on the camera. I am not interested in recording, or
webstream.
How do I want to do it? First, I wanted to activate the camera via
"python3 camera.startpreview()" But obviously I can't import in python
the camera instructions. So I created a very simple script;
import picamera
import time
camera=picamera.PiCamera()
camera.start_preview()
time.sleep (60)
And that is when I learned about the ENOSP error. Basically two
processes can not access the camera at the same time (motion and
python).
And this is where I am stucked. Unfortunately I can?t find anyone on
the internet who did and documented this.
SO now I have 2 options;
First, from motion.conf close the camera and then call the python
script that turns on the camera in the screen. CONS; The screen
backlight would be on all the time (though I am sure this has an easy
workaround)
Second, have motion send a constant stream from the camera to the
screen and activate/deactivate the backlight with "vcgencmd
display_power 1/0" on event start/stop.
Third, make a very complicated setup where motion starts streaming the
video in case of an event and a second process always listening and
showing that stream if available. CONS; It's way over my capabilities.
Thank you very much for your support

Could you not record video as usual but then just
stream or play the video file when it arrives maybe
using inotifywait -m or similar to trigger this?
The delete the file once played if you like.
CE.

I think the answer you are looking for is the video_pipe option. The
following documentation provides additional details.
