Failed to encode to Icecast2. #3019

Describe the bug
If I try to encode to the Icecast2 server, I get the following error message:

At ./trans.liq, line 13, char 186-192:
output.icecast(%mp3.cbr(bitrate=320,samplerate=44100,id3v2=true,stereo=true,internal_quality=0),host="172.20.0.9",port=2040,mount="/trans.mp3",user="source",password="test",icy_metadata="true",mksafe(s))

Error 5: this value has type
  string
but it should be a subtype of the type of the value at /usr/share/liquidsoap-lang/libs/icecast.liq, line 48, char 19-62
  [_]

To Reproduce

#!/usr/bin/liquidsoap
s=input.http("http://stream.dancewave.online:8080/dance.ogg")
s=source.on_metadata(s,print)
settings.init.allow_root.set(true)
settings.log.file.path.set("streamtranscoder.log")
settings.log.level.set(6)
settings.init.daemon.pidfile.set(true)
settings.init.daemon.pidfile.path.set("streamtranscoder.pid")
settings.log.stdout.set(true)
output.icecast(%mp3.cbr(bitrate=320,samplerate=44100,id3v2=true,stereo=true,internal_quality=0),host="172.20.0.9",port=2040,mount="/trans.mp3",user="source",password="test",icy_metadata="true",mksafe(s))

Expected behavior
The stream in the script should be encoded to another Icecast2 server.

Version details

OS: Debian 12 (bookworm)
Version Liquidsoap 2.2.0+git@2a3bf62

Install method
Nightly .deb package

The same script works fine with Debian 11 + Liquidsoap 2.2.0+git@471bd7c.

Hi @DroidU,
The output.icecast function signature changed in cd541d4.
https://www.liquidsoap.info/doc-dev/migrating.html#icecast-and-shoutcast-outputs

I think this will work

output.icecast(
  %mp3.cbr(
    bitrate=320,
    samplerate=44100,
    id3v2=true,
    stereo=true,
    internal_quality=0
  ),
  mksafe(s),
  host="172.20.0.9",
  port=2040,
  mount="/trans.mp3",
  user="source",
  password="test",
  send_icy_metadata=true
)

Thanks @vitoyucepi ! Also, you shouldn't need to specify send_icy_metadata!

Thank you, it works fine now.
But only if the source stream is mp3. If ogg, then song title is empty.

I just tried it with an external encoder, but it didn't work.
In the config, mp2enc is used to encode to mp1 to a very old target device.

#!/usr/bin/liquidsoap
s=input.http("http://stream.dancewave.online:8080/dance.ogg")
s=source.on_metadata(s,print)
settings.init.allow_root.set(true)
settings.log.file.path.set("streamtranscoder.log")
settings.log.level.set(6)
settings.init.daemon.pidfile.set(true)
settings.init.daemon.pidfile.path.set("streamtranscoder.pid")
settings.log.stdout.set(true)
output.icecast(
  %external(
    channels=2,
    samplerate=44100,
    header=true,
    restart_on_crash=true,
    process="mp2enc -v 0 -R 44100,2,16 -r 44100 -b 384 -l 1 -o -"
  ),
  format="audio/mpeg",
  host="172.20.0.9",
  port=2040,
  mount="/trans.mp3",
  user="source",
  password="test",
  send_icy_metadata=true,
  mksafe(s)
)

Cannot stop it with CTRL+C. It can only be killed.
If I use another external encoder, the same problem occurs.

Hi @DroidU,

There's a problem with the external encoder in the 2.1 and 2.2 branches.
Check #3020.

Rolling back to 2.0.7 will solve your problem partially, until it's fixed in the current versions.
