it can play both local and remote files

.pls playlist

[playlist]
numberofentries=2
Title1=File1 - archiveORg
File1=/home/andre/Documents/PZI/prototyping/blind-archive/sf-archive_frech/03actuel.ogg

File2=/home/andre/Documents/PZI/prototyping/blind-archive/sf-archive_frech/04comporte.ogg

Playing mono files

liquidsoap is set to stereo, so does not play mono files!

So what needs to be done is converting the mono into stereo Weĺl do through this .liq script:

#!/usr/bin/liquidsoap

mono_playlist = playlist("/home/andre/Documents/PZI/prototyping/blind-archive/liquidsoap/playlist-blind-remote-mono.pls")

mono_playlist_s = audio_to_stereo(mono_playlist)

out(mono_playlist_s)


Future

Make LS display metadata of the file on the stream!
