"""

Python part of radio playout (pypo)
|
||
|
|
|
||
|
|
This function acts as a gateway between liquidsoap and the obp-api.
|
||
|
|
Mainliy used to tell the plattform what pypo/LS 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 pythin 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 obp via api to tell about
|
||
|
