Generally, there are two seats in a wedding that can be broadcast live, one is a panoramic view of the fixed seat, and the other is a close-up of the sightseeing seat. Software implementation is also very troublesome and needs hardware support. If you are not afraid of trouble, you can manually adjust the LED input. Simply put, the live lines of two cameras are alternately plugged into the LED video input port, but there is a problem that the video will be disconnected between plugging and unplugging! By the way, two seats and people who plug in the line must have walkie-talkies to make the live broadcast more perfect! Wish you success!
