conflict between -A and -o

i'm trying to give auto number for the downloaded videos as well as keeping the exact name without any extra character last ne could be done by -o "%(title)s.%(ext)s"
but as you see the error there is a conflict
youtube-dl: error: using output template conflicts with using title, video ID or auto number

-A and -o can't be used together.

If you want to include an auto number in your filenames, simply include %(autonumber)s in your filename template. For instance, -o "%(autonumber)s_%(title)s.%(ext)s" may fit your needs.
