Liquidsoap supports various playlists formats. Those formats can be
and manually using
Most supported playlists format are strict, which means that
the decoder can be sure that is has found a correct playlist for that
format. Some other format, such as
m3u, however, may cause
false positive detections.
All formats are identified by their mime-type or content-type. Supported formats are the following:
audio/x-scpls: PLS format, strict
application/x-cue: CUE format, strict. This format’s usage is described below.
audio/mpegurl: M3U, non strict
Playlist files are parsed automatically when used in a
input.http operator. Each of these
two operators has specific options to specify how to pick up a track
from the playlist, e.g. pick a random track, the first one
Additionally, you can also manually parse and process a playlist
some programming magic. You can check the code source for
playlist.reloadable in our standard library for a detailed
Special case: CUE format
The CUE format originates from CD burning programs. They describe the set of tracks of a whole CD and are accompanied by a single file containing audio data for the whole CD.
This playlist format can be used in liquidsoap, using a
cue_cut operator. By default, the CUE playlist parser will
add metadata from cue-in and cue-out points for each track described in
the playlist, which you can then pass to
cue_cut to play
each track of the playlist. Something like:
You can find an example of using
cue_cut with cue sheets
here and a throughout explanation of how
seeking in liquidsoap works there.
The metadata added for cue-in and cue-out positions can be customized using the following configuration keys:
"liq_cue_in" settings.playlists.cue_in_metadata := "liq_cue_out"settings.playlists.cue_out_metadata :=
