Generate timelapse / startrails / keograms remotely

[melix]

Hi team,

I'm a newcomer to the AllSky community, so first let me thank you for your work! I have built an AllSky camera using a Raspberry Pi Zero 2 and I am facing the (expected) problem that generating the timelapse video takes literally hours. For example the process started around 6 am this morning, it's 12:30 now but it's still running. However, I made a little experiment: I used scp to copy all the tmp/sequence.../*.jpg files to my remote AllSky server, then basically copied the ffmpeg command that is running on the PI, but running it on the remote server instead. It took about 1m45s to generate the animation.

I would tend to think it's not unusual to have a remote server which would be more powerful than the PI. This would also have the advantage of putting less pressure on the sdcard, since on the Zero I have to use large swap value.

I was wondering if you could consider an option to do this automatically. I think I could probably use a trigger with the script module too, but I'm not sure how I could access the list of files to upload, nor if I could integrate this "smoothly" in place of the integrated module.

P.S: I theory, you could do this on any remote process server and fetch the result, then upload to the remote AllSky server, but as a first step reusing the same instance looks fine to me.

Thanks for your insights,

@melix,
Welcome to Allsky! I hope you find it as fun and rewarding as I have.

We already have a "to do" item for this in Issue #4007.
If you agree that's the same as what you've requested, please close this Discussion item.

I don't know when we'll get to this, however. We could use another programmer on the team to tackle requests like this.

Eric

Looks indeed the same, thanks! I wish I could help, but I'm not a Python dev, I'm in the Java world. Also quite busy with my own OSS projects :D
