Video doesn't start recording automatically after the unifi-video container restart.

[thomasjslin]

I set the video record mode as "always record", but it does not start recording automatically after the unifi-video container restart. I have to remove the unifi-video container and re-install it to make it in recording mode.

NAS: Synology DS1618+
Docker version: Docker version 18.09.8, build bfed4f5
UniFi-Video-Controller(beta version): docker pull pducharme/unifi-video-controller:beta
Note: My UVC G3 Flex, frimware: v4.22.13 can't be detected in version 4.10.11

Log from stop to start:

When updating, one would normally remove the old container. I actually run mine with the --rm option to make this more obvious. What do you mean by "reinstall"? Do you have to re-run all the unifi video setup? Or just re-run the Docker command?

[thomasjslin]

I meant reinstall is re-run the docker command. The problem would be the video won't start recording automatically if the NAS recover by UPS power. I have to re-run the docker command manually. If I don't aware the the NAS has been restart, the recording won't be start.

I have similar issues on a Linux host after reboot. I think it is something like Issue #178

I would suggest that you peek into your container (docker exec -it <container name> /bin/bash) when the failure accors and look if /var/cache/unifi-video/hls is existing.

If there is any mechanism on your platform to invoke a script at the end of the boot process you can add script which is destroying and restarting the container.

I believe I have this issue as well. When my server reboots (hard or soft) my container comes up and seemingly works 100% except for recording (I use on motion only but never records until I destroy/rebuild the container).
docker-compose down && docker-compose up -d and my video records again. Not sure why this happens.

Here is my compose file:

version: '3'

services:
  unifi-nvr:
    image: pducharme/unifi-video-controller:latest
    restart: always
    networks:
     vlan2:

      - PGID=100
    tmpfs:

You're right @thoschworks. This is undoubtedly related to issue #178 even though mine is not synology.

Turns out the problem was with my tmpfs line.

    tmpfs:
      - /var/cache/unifi-video/hls

Not sure why I had it this way but...
This caused the hls directory to be owned by root:root and ownership mask of 777 for a fresh start with docker-compose up -d. The recordings would work in this state. However if there was an abrupt end to the container and it's restart was incited by restart: always the hls directory would still be owned by root:root but would have the mask of 755 which resulted in error messages such as Mount point for /var/cache/unifi-video/hls not found in RecordingService-EmergencyShutOffCheck and recordings not occurring. I don't know why a destroy and rebuild would result in different file permission mask vs. an abrupt restart of the container.

after changing tmpfs to

 tmpfs:
      - /var/cache/unifi-video

hard and soft restarts of the container or host result in an hls directory owned by unifi-video:users or 99:100 and recording works perfectly. Cross posting to #178

[thoschworks]

Mounting the tmpfs at /var/cache/unifi-videois and was always the recommended way. Due to the Problems in Isse #178 @fryfrog added in 0a1789a a mechanism to fix the missing var/cache/unifi-video/hls. But this is only working if the tmpfs ist mounted at var/cache/unifi-video.

I have an idea, why there is a different behavior on the (first) start and the restart of a container (it is based on my analysis of the #178), but I did not had the time to make the necessary tests.
