 * Each stream can have multiple video and audio tracks, encoded with any codec (including H264, H265, VP8, VP9, MPEG2, MP3, AAC, Opus, PCM)
 * Serve multiple streams at once in separate paths
 * Encrypt streams with TLS (RTSPS)
+* Publish legacy RTMP streams
 * Pull and serve streams from other RTSP or RTMP servers, always or on-demand (RTSP proxy)
 * Authenticate readers and publishers separately
 * Redirect to other RTSP servers (load balancing)
