      Note

      • The browsers implement security policies for Web Real-Time Communication (WebRTC). Make sure that an HTTPS certificate is configured for the streaming domain of your RTS stream. 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 of 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.
