recording stuck at processing then disappeared?

[Przemek Jeske]

One of the recordings has been stuck with processing status for a couple of days in Greenlight ... then disappeared.

I think I found the files here:

bbb-docker/data/bigbluebutton/recording/process/presentation

I'll be verifying that those are indeed correct files (this is not my recording, I'm just helping out with it - and I'm waiting for the confirmation whether those are the correct files).

What are recommended steps in such situation? Is there a way to recover such lost recording and made them available in the regular panel?

I've started grep-ing the logs for the date and found some errors - attached filtered results.

Hi! What is the exact verion of BigBlueButton you run?

[Przemek Jeske]

docker images point to v3.0.4

[anton.g...@blindsidenetworks.com]

Hi

We've patched a few recording processing issues like https://github.com/bigbluebutton/bigbluebutton/issues/23131 in more recent BBB versions (latest is 3.0.12).

Now, I realize that the docker portion is indeed at the 3.0.4 release. Let me see what I can do about updating that...

how do I check that? And which component should I check:

bbb-docker-bbb-graphql-middleware-1
bbb-docker-bbb-graphql-server-1
bbb-docker-recordings-1
bbb-docker-bbb-web-1
bbb-docker-bbb-export-annotations-1
bbb-docker-bbb-pads-1
bbb-docker-bbb-graphql-actions-1
bbb-docker-etherpad-1
bbb-docker-greenlight-1
bbb-docker-webrtc-sfu-1
bbb-docker-apps-akka-1
bbb-docker-fsesl-akka-1
bbb-docker-bbb-webrtc-recorder-1
bbb-docker-collabora-1
bbb-docker-haproxy-1
bbb-docker-redis-1
bbb-docker-periodic-1
bbb-docker-nginx-1
bbb-docker-postgres-1
bbb-freeswitch
bbb-docker-coturn-1

It's pretty fresh install (installed like 2 weeks ago) - managed via Docker.

images point to v3.0.4

[Przemek Jeske]

Thx for info Anton. I'll keep an eye for updated images :) .

Is there a way to restart the processing? Apart from one missing recording I've just came one where the video is published (presentation format), but it is missing screen share part.

[Przemek Jeske]

Also - would love to see some manual on building / updating images for BBB. At this point BBB consists of many moving parts - thus it's trickier to start with it... And I'd love to update the setup I currently work with as there are more issues related to recording meetings. This time the recordings did not get stuck in processing / disappeared - but the processed output is missing screen share part, making it useless :(.

[Przemek Jeske]

In one of the rooms we have this problem with videos stuck at processing on a regular basis.

I"ve checked the logs. It seems the problem is similar to the one described on github that Anton linked.

```

Where is the info about the components to process stored? I wonder whether there's a way to manually tweak it so all webcams will be skipped when processing. No super value lost if there's a webcam missing - loosing entire presentation and video is far worse.
