RTSP server cannot Therefore RTSP server may not be launched because TCP ports in range 0-1000 are ub=navailable privileged and unavailable to non-root users. In In this case RTSP port should be changed, for example

To adjust RTSP playback parameters, for example, to change audio or video codec, SDP setting file rtsp_server.sdp should be used. Note that this file should contain WCS server IP address.
Playing H265 without transcoding
Since build 5.2.1577 it is possible to play MPEG-TS H265 stream via RTSP. To do this, H265 codec must be set in rtsp_server.sdp file:

Streams published in H264, VP8, or MPV codecs may not be played as H265! Use this codec to play MPEG-TS H265 streams only |
Dynamic codec detection
Since build 5.2.1592 codecs are detected dynamically for RTSP playback

In this case, if a stream is published as H264, VP8 or H265, and RTSP client supports the codec, the stream will be played via RTSP without transcoding. Audio codecs are detected by the same way.
