usage: video-streamer [-h] [-c CONFIG_FILE_PATH] [-tu TANGO_URI] [-hs HOST] [-p PORT] [-q QUALITY] [-s SIZE] [-of OUTPUT_FORMAT] [-id HASH] [-d]

mxcube-web Backend server command line utility.

options:
  -h, --help            show this help message and exit
  -c CONFIG_FILE_PATH, --config CONFIG_FILE_PATH
                        Configuration file path
  -tu TANGO_URI, --tango-uri TANGO_URI
                        Tango device URI
  -hs HOST, --host HOST
                        Host name to listen on for incomming client connections defualt (0.0.0.0)
  -p PORT, --port PORT  Port
  -q QUALITY, --quality QUALITY
                        Compresion rate/quality
  -s SIZE, --size SIZE  size
  -of OUTPUT_FORMAT, --output-format OUTPUT_FORMAT
                        output format, MPEG1 or MJPEG1
  -id HASH, --id HASH   Sream id
  -d, --debug           Debug true or false

There is the possibility to use a configuration file instead of command line arguments. All command line arguments except debug are ignored if a config file is used. The configuration file also makes it possible to configure several sources while the command line only allows configuration of a single source.

Example command line (for testing):

video-streamer -d -of MPEG1 -tu test

Example configuration file (config.json):

The configuration file format is JSON. A test image is used when the input_uri is set to "test". The example below creates one MPEG1 stream and one MJPEG stream from the test image. There is a defualt test/demo UI to see the video stream on http://localhost:[port]/ui. In example below case:

MPEG1: http://localhost:8000/ui

MJPEG: http://localhost:8001/ui

video-streamer -c config.json

config.json:
{
    "sources": {
        "0.0.0.0:8000": {
            "input_uri": "test",
            "quality": 4,
            "format": "MPEG1"
        },
        "0.0.0.0:8000": {
