Grabbing a static image

[fmarzocca]

How can I get a static image from my Argus Eco camera?

I tried with: ./neolink image <CameraName> --config=/homeAssets/neolink_config.toml --file-path=immagine

but it enters into a loop, sending BatteryInfo continuosly and the file immagine.jpeg has 0 bytes.

using neolink v. 0.5.16

That's interesting. I wasn't expecting to get battery information with that command. If anything the only kind of battery info we should get in that version would be the standard events the camera sends out (not really a loop coz it's on the event thread).

For image command to succeed the camera must support the snap command which seems to just be newer cameras

For older cameras there is the --use-stream option

[QuantumEntangledAndy]

If your camera dosent support the snap command it tends to just wait forever so i suspect that's why you think it's a loop. Try the --use-stream it starts the full video feed and uses gstreamer to dump it to file then close the feed.

then it hangs there and I have to Ctrl-C

Your missing a gstreamer plugin that can decode the h264 stream. Look into getting the av plugin set or something else that can handle h264

I'm running on a Raspberry (Debian bullseye) and I have installed all plugins you recommend....

For transcoding you also need gstreamer1.0-libav with --use-stream

It works! Thanks
