"Stop Recording" fails. Recording works and stops when conference is empty

Hi,

After struggling a while, I managed to get jibri record my meetings. My setup is maybe a little bit unusual :

  • jitsi meet server on NixOS on public IP
  • jibri recorders as debian/buster LXD containers on my LAN (using the jitsi unstable repository)

I opened port 5222 on the jitsi meet server to my lan clients, so they are able to login as jibri.

When I start to record a meeting, it works fine, the file is created on my recorder container. But when I click on the “stop recording” button and confirm to stop the recording, I get no errors on the client side, but the recording is keeping going on.

In the logs of jicofo, I can see this :

Mar 23 13:20:47 meetnix jicofo-start[930]: SEVERE: [646] org.jitsi.jicofo.recording.jibri.JibriSession.log() Error sending stop iq: org.jivesoftware.smack.XMPPException$XMPPErrorException: XMPP error reply received from jibribrewery@internal.auth.meet.mydomain/jitsi-rec01: XMPPError: bad-request - modify

When all participants are leaving the conference, the recording is finalized with the finalize script correctly.

I googled around, and cannot find anything usefull with this error.

On the jibri recorder side (journal -xe -f -u), I get a warning which I guess is unrelated :

Mar 19 19:57:34 jitsi-rec01 launch.sh[98]: WARNING: An illegal reflective access operation has occurred

Mar 19 19:57:34 jitsi-rec01 launch.sh[98]: WARNING: All illegal access operations will be denied in a future release

And in /var/log/jitsi/jibri/log0.txt I get :

Any idea where I should look to debug it further ?
I can post my config files if it helps

Looks like you installed Jibri 9.xxx which as I understand is not really in a usable state and has not been merged to master yet. There’s a flaky failure issue that’s still being worked on. You’d do best to either use the current stable or the last 8.xxx unstable.

Jibri 9 is indeed not stable, but I don’t recognize the error. Can you attach the entire jibri log? I’m curious to see what went wrong here.

Hi, thanks, I downgraded to jibri 8 from the stable repository, and it now works with stopping the recording !

I set it before to unstable because I had other issues, and maybe I followed a tutorial saying to do so.

For the rest of the logs of jibri 9, it’s not a lot helpful as far as I see. (the messages before are all LEVEL INFO and describe successfully events).
If it’s helping, let me know which logging options I should increase.

I was happy a little bit too fast. With jibri 8 the stop action is working, but it doesn’t wait until ffmpeg finished the encoding, and kills it which lets me with a broken file :

2021-03-23 19:39:01.314 SEVERE: [70] org.jitsi.jibri.util.JibriSubprocess.ffmpeg.stop() Error trying to gracefully stop ffmpeg, destroying forcibly
2021-03-23 19:39:01.319 INFO: [70] org.jitsi.jibri.util.JibriSubprocess.ffmpeg.stop() ffmpeg exited with value 137

anything weird in the ffmpeg logs?

No, if I watch the ffmpeg.0.txt file it shows the progress of encoding, and nothing is printed as it gets killed :

in log.0.txt :

The ffmpeg always needs about 30s to finish encoding after the meetings end. not sure if there is a way to speed it up (ffmpeg process uses only around 20% cpu).
Is there a way to configure the timeout after whtat the ffmpeg process is getting killed ?

This is strange, I’ve never known this to be the case. How did you determine that? Even if that were true, I wouldn’t think that it would resist being kill'd. Can you please include more of the ffmpeg log.

What is your Java version?

I installed the standart openjdk-11.-jre-headless from debian buster :
