A bit of software to display a video wall using MPV. This package is primarily intended for displaying rtsp streams from IP cameras.
This is the main branch of the video wall.
This software mainly controls a video wall made of MPV instances. There are three interfaces that control how the MPV instances run:
- MQTT PIR input (haldor compatible)
- MQTT control
- UDP control
There are two modes in which the wall is controlled:
- automatic
- manual
The MQTT event looks for an int not equal to zero on the configured event to trigger the screen.
In automatic mode, a motion event triggers the system to stay on for a period of time.
In manual mode, on and off is controlled by messaging through either MQTT or UDP.
This section provides a short overview of how the messages for decoding look.
A tuple-looking message is received: (<message>,<hmac>)
The <message> is data in JSON and utf-8. The <hmac> is base64.
The root element of the JSON message is a dictionary of keys and values. At the moment, there are three keys in the message that are important:
- restart
- auto
- force
A restart hoolean value of true signals to the program that the splitter needs to restart each MPV instance.
An auto boolean value controls whether the monitor should automatically control screen on / off and playing from the motion sensor.
A force boolean value controls whether the monitor is on / off. Receiving a valid force message will disable automatic mode.
This is a list of non-default python packages that may need to be downloaded for this software to work:
- python-mpv
- python-xlib
- paho-mqtt
- dataclasses-json
Modify startup applications in xfce to include this python script either with or without a terminal emulator attached.
An example configuration file will be provided.
