Lib to talk to blackmagic videohubs

Does not cache the labeling or routing information from the VideoHub. Reads and parses each time. see for protocol https://documents.blackmagicdesign.com/DeveloperManuals/VideohubDeveloperInformation.pdf

Lock protocol not really implemented as yet.

** only supports v2.8 of protocol at the moment **

usage

import from bmvideohub import VideoHub

vh = VideoHub("192.168.1.24")
input_labels = vh.get_input_labels()
print(input_labels)

examples

bmd_get_config

    python bmd_get_config.py --help
    usage: bmd_get_config.py [-h] --config CONFIG --ip IP [--port PORT]

    Set VideoHub config

    options:
    -h, --help       show this help message and exit
    --config CONFIG  config file to write
    --ip IP          ip address
    --port PORT      telnet port

example read settings from videohub write json (labels and routes)
