It should be ok as long as you followed Mikel's instructions after SSHing into the pi

Yeah probably. Not sure if that's available before the dtoverlay has been set please try /webcam/webrtc instead of /webcam/?action=stream

That could be a thing, can you post your crowsnest.log?
D_Jespersen (DJ_Designs)
is it meant to unly have 640x480

@d_jespersen try using ustreamer instead of camera-stream in your crowsnest.conf and revert to the old /webcam/?action=stream url. I can't see any options for camera control in the crowsnest log

I'd go back to crowsnest v3 i think
D_Jespersen (DJ_Designs)
and for how long can i do that?

for ever Well at least until something unexpected makes it not work anymore, i don't know what that would be. You'd have to update system packages for that to happen. Oh btw did you reboot the thing after installing crowsnest v4?

I had recently similar problems but with a v3 camera module. A few ideas to test: 1. Have you examined the output of libcamera-hello, to see it there are other problems? 2. Have you tried to take a pic from outside crowsnest to see if up to that point everything is ok? libcamera-still -o test.jpg 3. In my case I had to do again make install for camera-streamer alone. I can't see in your crowsnest.log that dependency being checked, i.e. I miss this line Dependency: 'camera-streamer' found in bin/camera-streamer/camera-streamer. in your log compared to mine.

Yes I’m Linux noob. Can you explain the steps I have to do.

To test 2)
cd ~/printer_data/config
libcamera-still -o test.jpg
cd ~/printer_data/config
libcamera-still -o test.jpg
That should generate a test.jpg that you can view in the mainsail machine tab. To test 3)
cd ~/crowsnest/bin/camera-streamer
make install
cd ~/crowsnest/bin/camera-streamer
make install
D_Jespersen (DJ_Designs)
gives a black screen on that test jpg
D_Jespersen (DJ_Designs)
this is test 3 it came with an error first notice after i did the reboot

I think this is just a matter of configuration in crowsnest.conf
D_Jespersen (DJ_Designs)
do i need to do this now
D_Jespersen (DJ_Designs)
tried all of those and they all give black screen except the lowest resolution

played around with resolution and found the magic number for a pi cam V2 and its 3200x1850

I've seen lately camera-streamer consuming quite a lot of system CPU. I also have a high resolution, I don't now if it's because of that, but watch out, specially if you see any klipper shutdown due to timming errors.
