| === Motion === | | === Watch result using a browser === |
|
| |
|
| * NO! use Python web server instead
| | Using the IP of the robot (in this case, robot Coco), the robot camera image can be viewed at this address: |
| * @todo update this page
| |
|
| |
|
| A motion camera ser is installed called "motion", it can detect motion and save video-clip, if motion is detected.
| | http://10.197.218.233:7123 |
| | |
| Motion detection is the primary purpose, but being able to see what the camera sees.
| |
| | |
| === Configuration file ===
| |
| | |
| Edit the configuration file
| |
| | |
| $ sudo nano /etc/motion/motion.conf
| |
|
| |
| # File to write log messages into. If not defined, stderr and syslog are used.
| |
| log_file /home/local/.motion/motion.log
| |
| # Target directory for pictures, snapshots and movies
| |
| target_dir /home/local/Video/motion
| |
| # Video device (e.g. /dev/video0) to be used for capturing.
| |
| videodevice /dev/video0
| |
| # The port number for the live stream.
| |
| stream_port 8081
| |
| # Restrict stream connections to the localhost (if 'stream_localhost on').
| |
| stream_localhost off
| |
| # Image width in pixels.
| |
| width 640
| |
| # Image height in pixels.
| |
| height 480
| |
| # Maximum number of frames to be captured per second.
| |
| framerate 5
| |
| | |
| === run motion ===
| |
| | |
| To run the streamer, SSH to the robot and start motion
| |
| | |
| $ motion
| |
| [0:motion] [NTC] [ALL] conf_load: Processing thread 0 - config file /etc/motion/motion.conf
| |
| [0:motion] [NTC] [ALL] motion_startup: Logging to file (/home/local/.motion/motion.log)
| |
| | |
| Stop by ctrl-C
| |
| | |
| Note! Remember to stop the streamer before using the camera for other purposes.
| |
| There is an alternative if you want both:
| |
| | |
| Start a loopback feature to create a copy with the same information when the camera is opened.
| |
| Run:
| |
| sudo modprobe v4l2loopback
| |
| | |
| When /dev/video0 is opened a /dev/video1 will be created (with the data determined by the first user).
| |
| | |
| - not tested much.
| |
| | |
| === View the stream ===
| |
| | |
| To view the result, use a browser to the address of the robot and port 8081, e.g. if the robot has IP '10.197.218.248':
| |
| | |
| 10.197.218.248:8081
| |
| | |
| You should now see a stream of default 640x480 at 5 FPS as default; more options are available in /etc/motion/motion.conf.

| change the /etc/motion/motion.conf

| | |
| * not much luck; it seems not compatible with libcamera.

| |
| sudo apt install libqt5dxcb-plugin

| to try
| |
| rpicam-vid --qt-preview

| But (also) not over ssh -X login
