At 23:39 (in Frigate is always wrong timezone) I tried to export recordings from the last 24 hours camera and tried from 1 hour “Front” and then downloaded them.
In the export tab it took an extremely long time (even for 1 hour record) until it was available then I was able to download it as .mp4.
It is not playable in Frigate, because when I try to play it a message appears with 'No video with supported format and MIME type found' . It is also not playable via vlc.

I have tried this several times before and it has never worked.

I can't figure it out from the log.
“Garage” is my other camera. There are also the usual error messages from that one, because the WLAN connection between the camera and the WLAN repeater is probably weak (the “front” camera is wired)

Here I've tried it with 1 hour at 04:50 (in frigate prob. 03:50. Not playable in Frigate "Export" Tab and not playable in VLC after download from Export-Tab):

The logs show the export is not saved correctly. If I had to guess the export is overwhelming the Pis CPU

[NickM-27]

In this case you could fix the error by increasing the number of open files allowed

Hello Nick,
yes, I also think that this may be the reason. This is also supported by the fact that the downloaded .mp4s from the “Export” Frigate tab do not seem to be downloaded completely and are therefore not playable.

Hm, is this a HAOS setting, because I don't see how to do this in the Frigate doc?

Thanks

[albotroz]

Would this approach be correct?

1. Install the SSH & Web Terminal Add-on

If you haven't already, install the SSH & Web Terminal add-on in Home Assistant.
Go to Settings → Add-ons → Add-on Store and search for it.
2. Open the Home Assistant OS Terminal

If you have SSH access, connect to Home Assistant OS via SSH. Otherwise, use the Web Terminal from the add-on.
3. Find the Docker Container Running Frigate

Since Home Assistant OS is based on Docker, you need to find the Frigate container name. Run:

docker ps --format "{{.Names}}"

Note down the name of the Frigate container (e.g., addon_ccab4aaf_frigate).
4. Increase the Maximum Open Files for Frigate

Run the following command to increase the limit (e.g., to 65535):

docker update --ulimit nofile=65535:65535 addon_ccab4aaf_frigate

If your Frigate container has a different name, replace addon_ccab4aaf_frigate accordingly.
5. Restart Home Assistant

After making this change, restart Home Assistant to apply the settings:

ha core restart

6. Verify That the Change Took Effect

After restarting, check if the new limit is applied by running:

docker exec -it addon_ccab4aaf_frigate ulimit -n

The output should show 65535 (or whatever value you set).

[NickM-27]

did not realize you are using HA OS, I am not sure if changing that would stick after rebooting

[albotroz]

I've checked within SSH-Terminal Addon in HAOS:

docker exec -it addon_ccab4aaf_frigate-fa sh -c "ulimit -n"

1073741816

docker exec -it addon_ccab4aaf_frigate-fa sh -c "ulimit -Sn && ulimit -Hn"

1073741816
1073741816

The result actually looks ok, doesn't it?
So there is actually no de facto limit to max. allowed open files.

Just tried the export-stuff again, but for recordings of 1 minute.
That worked. Added to Frigate “Export” section and was able to play and also download and play via VLC.

Tried again with 30minutes record.
While "exporting" process in SSH-Addon Terminal:
docker stats addon_ccab4aaf_frigate-fa

CONTAINER ID   NAME                        CPU %     MEM USAGE / LIMIT   MEM %     NET I/O          BLOCK I/O    PIDS

Even 30min segment is not playable in the Frigate-Export Dashboard, nor when downloading.

5min segment is not playable in the Frigate-Export Dashboard, nor when downloading too.
So only recordings of under 5min (1min) is possible with export, play and download.
shit... apparently RPI4 is just garbage for my intended use of 3 cameras.
