Python part of radio playout (pypo)
|
||||
|
||||
The main functions are "fetch" (./pypo_cli.py -f) and "push" (./pypo_cli.py -p)
|
||||
|
||||
There are two layers: scheduler & daypart (fallback)
|
||||
|
||||
The daypart is a fallback-layer generated by the playlists daypart-settings
|
||||
(eg a playlist creator can say that the list is good for Monday and Tues,
|
||||
between 14:00 and 16:00). So if there is nothing in the schedule, pypo will
|
||||
still play something (instead of silence..) This layer is optional.
|
||||
It is there so that you dont have a fallback player which plays the same 100
|
||||
tracks over and over again.
|
||||
|
||||
Attention & ToDos
|
||||
- liquidsoap does not like mono files! So we have to make sure that only files with
|
||||
2 channels are fed to LiquidSoap
|
||||
(solved: current = audio_to_stereo(current) - maybe not with ultimate performance)
