Raspberry Pi Camera is considered as USB webcam

yschroeder commented 4 years ago

What were you doing?

Connect a Raspberry Pi Camera (both the v1 and v2 have the problem) to the Pi running OctoPi
Change the camera_raspi_options in /boot/octopi.txt
Changes have no effect after restarting webcamd

What did you expect to happen?

Changes to camera_raspi_options change the output of mjpg_streamer in the OctoPrint UI.

What happened instead?

Camera picture was not affected by the options.

Did the same happen when running OctoPrint in safe mode?

Did not test, as this is not a problem of OctoPrint.

Version of OctoPi

0.17.0

Relevant output of `journalctl -u webcamd`

Workaround

Set camera="raspi" instead of camera="auto" in /boot/octopi.txt results in the changes to camera_raspi_options to be applied and the log of webcamd changes to the following:

Note: There was not USB webcam connected at any time to the Pi, it always uses the Raspberry Pi Camera!

wecamd seems to choose /dev/video0 when available, which is also true when using the Raspberry Pi camera. There should be a more sophisticated detection that checks if /dev/video0 is actually the Raspberry Pi camera and use that one instead of handling /dev/video0 like a USB webcam.

Are you using The Spaghetti Detective?

guysoft commented 4 years ago

@gotdsm95 Does Spaghetti Detective change anything?

yschroeder commented 4 years ago

@gotdsm95 I am not, and I also can't imagine how that would change anything.

gotdsm95 commented 4 years ago

It uses another type of streaming that can't coinside with mjpeg streamer. https://www.thespaghettidetective.com/docs/webcam-feed-is-laggy/

marcolivierroy commented 4 years ago

The camera gets recognized as a USB camera using the bcm2835-v4l2 driver. It is a normal behavior.

yschroeder commented 3 years ago

I guess #690 addresed this and this can be closed.
