The other program needs to use video2 rather than video1.?? So steps 5/6
need to be interchanged.
5.started motion server-?? service motion? start
6.Executed my program which uses /dev/video2 device
If the other program needs audio, then you would need to use ffmpeg or
something else to feed the camera into video2 and then have both the
other program as well as motion use that device for input.

Hello, I was wondering if anything changes if you use the RaspberryPi camera
board and a pen drive with Motion on a RaspberryPi 3 B+ or would it be just
like the webcams??
Thanks,Adam.?

What do you mean? Yes, it would be similar to a webcam, but it would
have a bunch of differences, depending on which webcam you are comparing
it to.
For me, one of the main benefits of the RPi + RPi Cam are better
quality, lower cost, increased flexibility. However, that last one is
also the main disadvantage.
Please be more specific on your needs and we can hopefully provide
better advice.
Regards,
Adam
