I am trying to use Raspberry pi as a web camera streaming server. I am following this tutorial which uses Motion tool.
When I start the motion service, it exists without giving me an error and when I go to the streaming URL(http://myrpi:8081) I get nothing there.
I tried to take a few pictures using FFmpeg and it worked.
ffmpeg -f video4linux2 -i /dev/video0 -vframes 2 test%3d.jpeg
This means my USB Web camera is working with the raspberry pi. I am attaching configuration and log file contents below. Please let me know if you need more details.
-- Thank you in advance.

- OS Version: Raspbian GNU/Linux 11 (bullseye)
