Using libcamera

We have this new utility since Bullseye (buster 2022). While taking the pictures for timelapses goes through libcamera-still, you can also use other commands, e.g. Videostreaming libcamera-vid -t 0 --width 1920 --height 1080 --codec h264 --inline --listen -o tcp://0.0.0.0:8888 and vlc tcp/h264://192.168.2.138:8888/ to manually adjust the objective, so you get sharp images (or libcamera-vid -t 0 --width 4056 --height 3040 --codec mjpeg --framerate 10 --inline --listen -o tcp://0.0.0.0:8888 and vlc tcp/mjpeg://192.168.2.150:8888/).

I've failed to use this to make captures with more than 370 frames on my RaspberryPi 3 (it just crashes without a stack), so now we are back to scheduling each frame ourselves again. Also, I tried both packages node-libcamera and libcamera (which is a bit smaller), but we might aswell have full control about the spawned process without using additional dependencies

Dependencies

On Debian (Bullseye), install nodejs (with Node Version Manager) and ffmpeg

Test libcamera-still commands, if necessary edit the dtoverlay setting, e.g.

sudo nano /boot/firmware/config.txt

sudo apt-get update
sudo apt-get install ffmpeg -y
curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.40.0/install.sh | bash
nvm install --lts
npm i -g pm2 tsx

I don't know if there is a copyright on it, I just liked the loading animation a lot.
