no ffmpeg on remote server --> no video thumbnails

[astrocusanus]

Hi,
I host my allsky website on a remote server, not on the pi. After a while of fiddeling around I managed to get the keograms and startrail image archive working properly. However, the in the timelapse video section there are no thumbnails. I realized that the reason is probably because there is no ffmpeg installed on my web server and I don't have the rights to install it.

Error message:
Failed to make thumbnail for allsky-20220610.mp4 after 2 attempts.
Last command: ffmpeg -ss 00:00:00 -i 'allsky-20220610.mp4' -filter:v scale='100:-1' -frames:v 1 './allsky-20220610.jpg'

Is there a way to make the video thumbnails on the pi and to upload them to the videos/thumbnails folder of the remote server? I suppose I would have to modify the upload.sh (and uploadForDay.sh) file?
Best wishes

@EricClaeys : Did you find the time to look into the logs I uploaded (Thread: Image flicker at dusk and dawn)?

@astrocusanus. Christof, the next version of Allsky allows creating timelapse video thumbnails on the Pi and uploading to the website' videos/thumbnails folder on the Pi and/or a remote server. In the meantime you can run the ffmpeg command manually and upload them.

I briefly looked at your logs and another person's similar logs. I'm not sure what to do, though, since nighttime uses the camera's auto exposure, not our daytime code. You can try changing the Version 0.8 Exposure option, and lowering the USB Bandwidth setting. At some point we will port out auto exposure algorithm from the RPiHQ camera to the ZWO which I hope will fix the problem.

Ok, thank you Eric. I'll do as you say and wait for the next version.
Cheers

Hi @EricClaeys ,
I'm referring to my post from 14 June 2022.
Yesterday I installed the latest allsky version. Is there now a way to have the timelapse video thumbnails created on the RPI and have them uploaded to the web server? Creating and uploading them manually is very tedious.
Best regards
Christof

Yes, set TIMELAPSE_UPLOAD_THUMBNAIL to true in config.sh.

Thank you @EricClaeys ,
I wonder why I didn't notice this option myself.
Sorry for stealing your time and thank you very much!

@EricClaeys , seems I did see it. The option was set to true. However, no time lapse thumbnail has been created last night. I don't find it in the image folder. ffmpeg is installed. Do I need TIMELAPSE-EXTRA-PARAMETERS set?

@astrocusanus The thumbnails for the Allsky Website go in the videos/thumbnails, keogram/thumbnails, and startrails/thumbnails directories on the Website. There is no "image" folder on the Website.
If you don't see the thumbnails when you go to your URL, and you don't see them in the directories above when you log into your server, than look in /var/log/allsky.log for error messages. Look a little after the night-to-day transition.
