Error 8: Unsupported format: %mp3()

anoniniarz commented 6 months ago

I upgraded from 2.0.2 to 2.2.3 using opam. liquidsoap was working kinda fina (was playing music, but metadata was not working), so I decided to upgrade using opam hoping that it will fix this issue. And now I am getting error about unsupported format, no matter what format I am using (I tried with opus and vorbis, same error). Here is my config

set("log.level", 3)

playlist = playlist.safe("playlist.m3u")

output.icecast(
  %mp3(bitrate=128),  
  host = "127.0.0.1",
  port = ,
  mount = "/mount,
  password = "pasword",
  fallible=true,
  send_icy_metadata = true,
  playlist
)

What am I doing wrong? My machine is running Ubuntu 22.04

Hi @anoniniarz, I suppose you have build liquidsoap without mp3 support. Can you paste the liquidsoap --build-config?

If you're not very familiar with opam, there are some other options for ubuntu 22.04.

Install from the release artifact package. https://github.com/savonet/liquidsoap/releases/tag/v2.2.5
Use the container image. https://hub.docker.com/r/savonet/liquidsoap

Hello @vitoyucepi , thanks for fast reply! I indeed did not install mp3 support, I wam not familiar with opam and assumed that it could use libraries from system, apparently it does not and after installing them it works now. But issue with title persists. Earlier it was sending "Unknown" title to icecast, now it's just empty string. How do I fix this? I used this command to install

opam install taglib mad lame vorbis cry samplerate liquidsoap.2.3.3

do I need something else for metadata?

vitoyucepi commented 6 months ago

It would be very helpful in debugging this problem if you could share

`liquidsoap --build-config' so I can check which modules are enabled.
`opam list' to check the list of installed opam packages.

opam and assumed that it could use libraries from system

Most packages rely on system libraries, but liquidsoap uses ocaml interfaces for them. lame is one of these interfaces. By the way, why did you install liquidsoap 2.2.3 instead of 2.2.5?

By the way, why did you install liquidsoap 2.2.3 instead of 2.2.5?

At first I thought that maybe downgrade will resolve "unsupported format" issue, but since it is not the case I will upgrade to 2.2.5 later

vitoyucepi commented 6 months ago

Your problem looks strange. I just set up a new VM with Ubuntu 22.04 and I don't have this problem. Maybe there's something wrong with the playlist?

Can you check if my script works or not?

p = playlist("playlist.m3u")

p.on_metadata(print)

output.icecast(
  %mp3,
  p,
  host="127.0.0.1",
  port=8000,
  mount="/mount,
  password="password",
  fallible=true,
)

It should show metadata for each file in the process log. Like this.

[("on_air_timestamp", "1716485467.00"), ("kind", "{audio=pcm(stereo)}"), ("decoder", "mad"), ("title", "music_2"), ("filename", "/home/ubuntu/music/2.mp3"), ("temporary", "false"), ("source", "music"), ("initial_uri", "/home/ubuntu/music/2.mp3"), ("encoder", "Lavf58.76.100"), ("status", "playing"), ("on_air", "2024/05/23 17:31:07"), ("rid", "2")]

And that's all. What on earth is this? Metadata in the files seems to be correct, ezstream does not have issues with sending it to icecast

vitoyucepi commented 6 months ago

Looks good, the long line is just an image. Here's another attempt to display metadata, check that too.

p = playlist("playlist.m3u")

def custom_log(m)
  print(metadata.cover.remove(m))
end

p.on_metadata(custom_log)

output.icecast(
  %mp3,
  p,

It looks like your file has no title or something.

Can you extract tags from the file? For example, you could try ffprobe /etc/liquidsoap/media/filename1.mp3 and see if there are any tags. If there are no tags, then the behavior is correct.

By the way, do you have ffmpeg installed on your system, because you can only build liquidsoap with ffmpeg support. Like this opam install liquidsoap ffmpeg, but you don't need to do that right now.

anoniniarz commented 6 months ago

I've run one file through ffprobe, and there was no metadata for title, artist, or album. Seems like they've been lost in conversion from ogg to mp3. It was confusing because ezstream did display artist and title, but apparently it took data from filename. I will re-convert everything later. So liquidsoap cannot display filename? Some songs, for example ripped from youtube, don't have metadata and adding it would be pain in the butt. And no, I do not have ffmpeg in opam environment, but generally I do. I thought that ffmpeg is needed only if I want to re-encode
