Been making timelapses with ffmpeg since forever, such a great tool. I try to always have a cam pointed at the sky and upload a snapshot every minute. A telegram command triggers the creation of a timelapse with a similar cli command like the OP. https://www.youtube.com/watch?v=5GvaFBzOu2c

Nice! What equipment do you use to capture? And does it push to some server... running RTSP?
I use an old Android phone with a long deprecated app called MobileWebCam (still available on certain sites) I removed the battery and connected the charger directly. It uploads a picture every minute, a Node.js backend creates the timelapse with ffmpeg. Currently experimenting with a TP-Link C520 cam and a Raspberry Pi. You can point the camera to different positions using ONVIF, use ffmpeg to grab the stream and take a snapshot, then process this again on the server. Downside is the wide angle / fish eye lens and occasionally a corrupted stream snapshot.
Thank you, was looking for a cheap webcam security set up using the great near-wasted cameras on older android phones.
If you want an all sky solution, zwoastro.com ships an all sky lens with many of their small sensor planetary cameras. There's also a selection of software to handle the photos, making time-lapse, uploading etc. It came in really useful for seeing the Aurora outburst. Here's a short write up I did for my local club recently: https://m.facebook.com/story.php?id=101640086556073&story_fb...

I'm also working on a new one that uses an ASI533 Pro and a 4mm lens from a mirrorless camera to get better quality images.
