Hello, Thanks for the tip about source.on_end. I've been reading the documentation a lot over the last few days and still missed that.
I'm trying to just use that function to skip the currently playing track when it triggers, but I can't seem to get the syntax down. Would you mind having a look? audio = playlist(prefix="annotate:liq_cue_in=\"120.\":",prefetch=4,loop=true,mode="randomize", "/home/liquidsoap/Audio") audio = cue_cut(cue_in_metadata="liq_cue_in", audio) audio = source.on_end(id="audio",delay=120.,source.skip(audio)) I realize that if this were to work, it may not cut at exactly two minutes, but it should be close enough, and would save me having to store the duration of all of my audio in order to query it for each track.
