3.2.10 RTP
The Real-time Transport Protocol (RTP) is an Internet protocol standard to manage the real-time transmission of
multimedia, such as VLC player.
The media player you want to use for remote access must support RTP transmission for this function to work
normally.
Note: When you're about to end the remote access, please press the stop button on your media player
first, and then close the program. This is to ensure the server receives the stop command, and
also help to protect the server from redundant data transmission.
