I have the same issue as mentioned in this post.
Also, it has been noticed that after disconnecting the call, jibri keep recording the blank page e.g. if the recording starts for a session of 20 secs, the recorded file will be of 30-40 sec in which the last extra secs are blank and avatar is displaying(no video) in the background. so it makes double the size of the actual session. But not a big issue when we have TBs of disks.
But the big issue arises when jibri failed to stop the recording and doesn’t allow to restart, or shutdown the VM. When I forcefully stopped and closed the VM machine, and later checked the sie, it was merely 48 bytes but it occupied 2.5GB space. I don’t know where the raw has been saved and from where to delete it.
