"""
|
|
Python part of radio playout (pypo)
|
|
|
|
This function acts as a gateway between liquidsoap and the server API.
|
|
Mainly used to tell the platform what pypo/liquidsoap does.
|
|
|
|
Main case:
|
|
- whenever LS starts playing a new track, its on_metadata callback calls
|
|
a function in ls (notify(m)) which then calls the python script here
|
|
with the currently starting filename as parameter
|
|
- this python script takes this parameter, tries to extract the actual
|
|
media id from it, and then calls back to the API to tell about it about it.
