Greg, I believe I first set it up to be V4L2SRC, but an error occurred, and I read in the custom capture devices page that I should use custom producer - or that's what I understood. I cannot make the modifications now, but I will do it later and let you know what happened.
Thanks a lot! I appreciate the quick responses.
