Video Recording Error

[KandimallaPrat]

Hi, I just set up the node and a couple of ethoscopes. The live tracking works as expected - saving the txt and db files. However, I am unable to record videos for offline tracking. Attached is the screenshot of the issue I have been having. While the recording seems to start (I can see a live stream on the page), there is nothing listed in the Run ID - the video is not saved anywhere.

Any suggestions on how to fix this?

I could not find it now in the documentation, but in order to be able to save the videos, the service ethoscope_video_backup.service has to be started in the node: systemctl start ethoscope_video_backup.service Videos will be saved to the default path (if nothing else specified): /ethoscope_data/videos In order to help you further, please paste the status of the ethoscope_video_backup service.

Hi @KandimallaPrat - the video is working and it is saved in chunks of h264 files in a local folder in the ethoscope. The path looks something like this:

[root@ETHOSCOPE144 2020-05-06_09-53-32]# pwd 
/ethoscope_data/results/144683573e2a4c1588e1b23553a24eca/ETHOSCOPE_144/2020-05-06_09-53-32
[root@ETHOSCOPE144 2020-05-06_09-53-32]# ls -lh
total 25M

To transfer those videos to the node you would have to make sure your ethoscope_video_backup.service is running

You can check that's the case in the node administration page:

If the backup service is running, you would see the video appear on your node, as @pepelisu just wrote.

I agree that the output of the ethoscope window could be a bit more clear regarding the state of this. I have just made some changes to the UI to make it more explicit and I'll commit it soon.

Hi @pepelisu and @ggilestro, Thank you very much for the prompt clarification. 1) The ethoscope_video_backup service has been active during the recording sessions.

2) I have just updated the node. I also checked to make sure that the ethoscope_video_backup service is active in the Node Administration page.

I still run into a similar issue. The video is not saved anywhere on the Node (the node administration page shows the path as /ethoscope_data/videos).

I then checked the local folders on the ethoscope: total 0 This is the case for each recording session that I tried over the past 2 days.

Again, thank you very much for your help!

That's weird. I'll need more info to debug this. Can you post a copy of the logs for both the node and the ethoscope?

Is it possible that the ethoscope memory (SD card) is already full of video content? There is this line that is worrying me. May 08 10:27:59 ETHOSCOPE001 python3[943]: OSError: [Errno 28] No space left on device

[ggilestro]

Yes - @pepelisu is right. You are using a version of the SD image in which the ethoscope_data folder is mapped to the root partition instead of the data partition and therefore it fills up with video very quickly. I have actually fixed that earlier in May so if you burn a new image you should be alright. Sorry about that.

[KandimallaPrat]

Hi @pepelisu and @ggilestro, Thank you very much! The ethoscope log shows that the root partition is 98%full. I just assumed that everything was being saved in the mmcblk0p3 partition which is 23GB and only 2% used. I will burn the new image. Thank you very much for your help.
