I’m trying to connect a camera via USB, it detects /dev/video51
/dev/video52
/dev/media6

But, once I follow the Hardware Encoding steps from the documentation I get the attached error.

Post a console log of your issue below:

Hello @3l3k10, Welcome to the community!

Does the encoder show similar clock errors with the other video device (/dev/video52) as well ?

Could you provide more details of your USB Camera as well ?

Regards.

Hello @Electr1 thanks for your welcome.

This is what I get when I try /dev/video52 it doesn’t seem to recognize it as a video node.

The reference of the camera is the following: Allinko 550 FULL HD 1080P, link: https://www.amazon.com/Allinko-Microphone-Compatible-Windows-Webcams/dp/B07MBPK3WY/ref=cm_cr_arp_d_product_top?ie=UTF8

I tried the same camera with VIM4, and it worked correctly, with the following command.

gst-launch-1.0 -v v4l2src device=/dev/video0 io-mode=mmap ! video/x-raw,format=YUY2,width=1920,height=1080 ! queue ! amljpegenc ! avimux ! filesink location=videos.avi & sleep 300; pkill -f “gst-launch-1.0”

I can play the recorded video successfully. I had the intention of testing the same camera with the Edge2, to see which SBCs work better on

greetings

@3l3k10 perhaps you need to change your arguments when using the Edge2, if your webcam only support raw output instead of jpeg out you need to use image/x-raw, format=YUY2 instead of image/jpeg.
