How to use RTSP Video with OBS - Chapter 26 - OBS Superuser Guidebook

Real Time Streaming Protocol (RTSP) is a convenient way to connect video sources to OBS because it is widely available on network connected cameras. From simple security cameras to advanced production encoders, you will likely find that most network connected video devices have the ability to produce an RTSP video feed that you can pull into OBS as a source. RTSP video sources can be connected using the “Media Source” source type. Using RTSP video requires some networking knowledge because the device you are connecting to should have a unique IP address for communication. NDI is superior to RTSP in a variety of ways. For example, NDI video sources on your network can be discovered automatically and that simplifies the process of connecting to video sources. NDI also features lower latency than RTSP in many cases which helps to reduce audio synchronization issues. Both RTSP and NDI video sources can benefit when they are synchronized with an Network Time Protocol (NTP) server. Each device that you connect with over your network should be synchronized with the same NTP time server that your computer is using. Network Time Protocol (NTP) is a networking protocol for time synchronization and IP video connections. Network-connected cameras can use this technology to synchronize multiple RTSP and NDI® video feeds. NTP servers are available all over the world and therefore video productions can choose local time servers to achieve the best performance. An NTP time server can be...
