Hi NXP team:
I have a problem recently.
When I plug in the USB camera,I found that the newly inserted USB camera and device node started from video2.
Now,I want to delete the device node of /dev/video0 and /dev/video1 , Let the newly inserted USB camera register from video0 . How to achieve it.
(The development board I use is imx8mq evk, Image: android_p9.0.0_1.0.0-ga_image_8mqevk)
BRs
thanks
Probably video0 and video1 are listed persistently in udev. I mean the file named like /etc/udev/rules.d/*-android.rules (here I replaced some digits with "*").
Please try to clean this file from /dev/video* items.
Hi Victor Linnik
1) In the dev directory did not have such file.
If I remove the /dev/video0 and /dev/video1 ,then plug in the USB camera,it still register from /dev/video2
How to change it. ?
2) I found that the dev / video0 and / dev / Video1 device nodes are registered because of the following code
What are these two device nodes used for? Can you help explain or have related documents introduced?
BRS
thanks
I mean udev configration file under /etc/udev/rules.d/.
