Recording live broadcast breaks liquidsoap #3537

netbladenl · 2023-11-15T13:35:48Z

Describe the bug
I'm using the latest rolling release of Azuracast, and when the function to record live broadcasts is on liquidsoap stops working correctly. ID3 information is not being showed correctly. And when the streamer is disconnecting most of the time the autodj of liquidsoap dont play. and if it works you can hear the last seconds of the song being played before the streamer connects instead of directly a new song.

To Reproduce
In azuracast you have to go to edit station profile -> streamers/dj's
Turn on the option "Record Live Broadcasts" connect with butt or anything else that is able to set up a shoutcast/icecast stream and disconnect after a minute. Most likely the autodj doesnt play as it should. Turning this off solves the problem but live streamers wont be recorded.

Expected behavior
When streamer disconnects the autodj should be playing, and when the streamer is connected the ID3 information should be showed instead of the song before playing when the streamer connects

Version details

OS: Ubuntu
Version 22.04.3

Hi @netbladenl,
I think the problem is in liquidsoap. I can't fix it, but I can reproduce it. It's not necessary for you to repeat the reproduction steps.

Reproduction

Start liquidsoap with the following script

s = sine(200.)

l = input.harbor("/test", port=8000)

l = metadata.map(fun(_) -> [], l)

r = fallback([l, s], track_sensitive=false)

output.file(%mp3, {"/tmp/f.mp3"}, l, fallible=true)
output.dummy(r)

It will start and output [switch:3] Switch to sine.
Stream with the ffmpeg command.
ffmpeg -hide_banner -re -f lavfi -i "sine=frequency=1000:duration=20" -b:a 128k -c:a mp3 -f mp3 icecast://source:hackme@127.0.0.1:8010/test.
After the stream is finished, liquidsoap will become unresponsive.
It will also output in a loop.
```
[output_file:2] Warning: there may be an infinite sequence of empty tracks!
```

liquidsoap: since 2.2.2

toots · 2023-11-16T15:50:54Z

Thanks so much for the detailed steps @vitoyucepi. I haven't been able to reproduce, however, either with my local dev env or using savonet/liquidsoap:v2.2.2 on docker. Could you provide more details on the reproduction steps on your end?

Thanks!

OK, here's a docker-compose setup.

compose.yaml

version: "3.8"
services:
  liquidsoap:
    image: savonet/liquidsoap:v2.2.2
    command:
      - "/tmp/test/main.liq"
    ports:
      - "127.0.0.1:8010:8000"
    logging:
      driver: "json-file"
      options:
        max-size: "1m"
        max-file: "3"
    volumes:
      - ./:/tmp/test

mail.liq

s = sine(200.)

l = input.harbor("/test", port=8000)

l = metadata.map(fun(_) -> [], l)

r = fallback([l, s], track_sensitive=false)

output.file(%mp3, {"/tmp/f.mp3"}, l, fallible=true)
output.dummy(r)

Start the compose project with the docker compose up command in the first terminal.
In the second terminal, open docker stats and look for cpu usage.
top will also work.
In the third terminal, start the stream with ffmpeg -hide_banner -re -f lavfi -i "sine=frequency=1000:duration=30" -b:a 128k -c:a mp3 -f mp3 icecast://source:hackme@127.0.0.1:8010/test.
I'm not sure if the duration of the stream makes any difference.

In the stats monitor, you'll see the following sequence of events.

While loading liquidsoap, the container will use 100% of the CPU.
That's okay.

I can reproduce now but weirdly enough, on amd64 only. The issue does not seem to pop out on arm64, that's puzzling.

SkillenUK · 2023-11-18T16:04:53Z

I'm having this same issue in 2.2.2. I just came on here to see if there was a solution, I may just roll back to 2.2.1 for now.

toots · 2023-11-20T16:43:16Z

I'll get to this as soon as possible. Thanks for y'all patience.

toots · 2023-11-25T23:56:32Z

I believe that the changes in this CI build might fix the problem: https://github.com/savonet/liquidsoap/actions/runs/6991394869 Any chance one of y'all could test them?

I was able to test and confirm that the latest commit on the fix-has-ticked-2.2.x branch does fix the issue.

Reproduction was tricky because it relied on two elements:

Source sharing, achieved via the two outputs
Partial frame fill.

Partial frame fill can depend on timing such as when the harbor gets available. By changing the duration to 20.03 (frame sizes are 0.04 by default), I was able to make the test case reproducible.

The autodj dont come back, after the streamer disconnects

Sorry to hear. How did you test it? The rolling release guide hasn't completed yet..

netbladenl · 2023-11-28T13:18:05Z

commit on the fix-has-ticked-2.2.x branch does fix the issue.

Oh I thought that the patch was already released, my bad. I've asked Buster to use the newest rolling release of liquidsoap with the Azuracast rolling release.
Maybe I'm a bit to fast.

vitoyucepi · 2023-11-28T15:13:43Z

2.2.3+git@4181a8c works fine.

toots · 2023-11-28T16:31:52Z

The build of rolling-release-v2.2.x including the fix has just finished!

netbladenl · 2023-11-29T06:50:50Z

The problem has been resolved, thanks for all of your help!
