UNDEFINED VARIABLE CUE #4378

Hi,

I started to have a problem with cue sheets under 2.2.5 on Ubuntu 24 so disabled them; however, having now upgraded to 2.3.1, I want to start using them again. Part of my script includes:

music = cue(
    file = "/home/radio/firepit/StandardTime.mp3",
    cue = "/home/radio/firepit/StandardTime.cue"
)

I get the message 'Error 4: Undefined variable cue'.

From what I've found, this is because I do not have the cue sheet functionality installed. What I have done to try and fix this is:

opam remove liquidsoap
opam pin remove liquidsoap
opam clean
sudo apt-get update
sudo apt-get install libcue-dev
opam pin add -ny liquidsoap git+https://github.com/savonet/liquidsoap
opam install liquidsoap

However, I still get the same error and I don't see any reference to libcue-dev when I issue

opam list

Under 2.2.5 I wasn't using the cue function but thought this was an option under 2.3.1. Is this not the case, please?

How do I ensure that the libcue-dev package is compiled into liquidsoap 2.3.1?

Thanks for any help.

Hi @glenbuck1,
What's the cue()?
Could you please add the outputs of liquidsoap --build-config and opam list?

@glenbuck1 cue files are parsed as regular playlists. You should use the playlist operator and point to the cue file.

Mea culpa...I hold my hands up...I was using AI in the hopes that it would give me a better solution than I was working out for myself!

As mentioned, I was having some issues when previously using the cue sheets and parsing them with the playlist function...the ending of voice breaks between tracks was being clipped off by a couple of seconds even though crossfading was turned off and the cue sheet locations were accurate. Any ideas why this might be the case, please?

Also, my apologies for wasting your time with AI hallucinations!

No pb!

The cue file parser was entirely rewritten in 2.3.1 so, hopefully, it should work better now!

If you need more finer-grained manipulations, you can use playlist.parse.cue.full which will give you the full parsed cue file.

Hi, Vito Given Romain’s comment about AI hallucination, I shan’t send you the output of those commands and waste your time further. Thanks for your help, though.

Hi,

When running the following in my script, track 1 of the file is identified and the title displayed but none of the subsequent ones.

CueStandard="/home/radio/firepit/StandardTime.cue"
StandardTime=mksafe(normalize(playlist(CueStandard, loop=false, mode="normal")))

def disable_fades(metadata)
fades = [
("liq_fade_in", "0"),
("liq_fade_out", "0")
]
list.append(fades, metadata)
end

StandardTime = metadata.map(disable_fades, StandardTime)

This is the code I used in 2.2.5 so I'm assuming the rewrite has changed things! However, I am struggling to understand the playlist.parse.cue.full syntax and could really do with a working example to crib from!

Are there any sites with Liquidsoap examples, please...I haven't been able to find any as yet, unfortunately.

Once more, thanks for any help.

Richard Bartholomew

Thanks for the very quick fix, Romain. This has definitely fixed the problem of not displaying track titles. However, I still have the issue of portions of the file being clipped. As you can see from the below extract, the first actual track begins at 01:15:00 into the file but up until that point, there are promos being played which I have tried to allow for by inserting a Track 00. Could this be causing the problem, do you think, and, if so, how do I ensure that the first minute and 15 seconds are played? Would a copy of the full cue sheet and file help in understanding the issue? Thanks again.

You should try adding a INDEX 00 to your track. The time between INDEX 00 and INDEX 01 is what was pre-track/silence in the original audio CD burners (for which CUE was designed for).

If you add a INDEX 00 for instance before the commercial start and INDEX 01 where the track actually starts, the playlist parser should be smart enough to end the previous track at the next track's INDEX 00 and start the next track at INDEX 01.

Hi, I added an Index 00 to match Track 00 and left the Track 01 and Index 01 pair in place. This seems to have made things worse as the first minute and 15 seconds were not played and track 2 started before it should do, cutting off the end of the voice break preceding it! Any other suggestions, please?

You need something like this:

FILE "/home/radio/firepit/StandardTime.mp3" MP3
TRACK 01 AUDIO
TITLE "Moonlight Serenade"
PERFORMER "Big Bands In Hi-Fi"
REM ALBUM "Volume 1 : Let's Dance - (Disc2"
INDEX 01 00:00:00
TRACK 02 AUDIO
TITLE "The Laughs are on me from Frank Sinatra Balids"
PERFORMER "frank sinatra"
INDEX 00 xx:yy:zz <-- Timecode for commercial before track 2
INDEX 01 xx:yy:zz <-- Timecode for actual track 2 start

Hi,

Thanks for your suggestion but, unfortunately, it won't work as I do not have start times for any commercials or voice breaks.

The cue sheet is generated by a broadcasting package called StationPlaylist Studio whilst presenters are voice tracking a show. Therefore, what happens is that a song plays and then the presenter speaks and cues up the next track to play and it is this next track whose start point is placed in the cue sheet. This carries on for the length of the show being voice tracked.

What I end up with is a cue sheet with the start position of each song being played and nothing for the voice breaks.

What currently happens is that the songs/tracks start correctly but the end of the preceding voice break or commercial is clipped.

Any further suggestions gratefully received.

Richard Bartholomew
