      Note

      • Make sure that an HTTPS certificate is configured for the streaming domain of your RTS stream due to the Web Real-Time Communications (WebRTC) security policy of browsers. Otherwise, the stream may fail to play.

      • Web RTS SDK does not support videos that contain B-frames and audio that is encoded in the AAC format. If the video or audio in your stream does not meet this requirement, transcode the stream and use the URL of the transcoded stream as the streaming URL. For more information about transcoding, see Configure RTS transcoding.
