Overview

Since build 5.2.902 it it is possible to publish RTP stream via RTSP directly to WCS.  Both Both TCP interleaved and UDP transports are supported. This can be useful to publish H264+Opus streams from hardware or software encoder supporting RTSP. Since build 5.2.1584, H265 codec is also supported for publishing.

Codecs supported

  • H264
  • H265 (since build 5.2.1584)
  • VP8
  • AAC
  • Opus

3. Open Player application. Set stream name to "Stream" field and click "Start". The stream captured playback begins.

H265 publishing

Since build 5.2.1584, RTP stream in H265 codec may be published via RTSP

Code Block
languagebash
themeRDark
ffmpeg -re -i source.mp4 -c:v libx265 -c:a aac -b:a 160k -bsf:v hevc_mp4toannexb -keyint_min 60 -profile:v main -preset veryfast -x265-params crf=23:bframes=0 -f rtsp -rtsp_transport tcp rtsp://test1.flashphoner.com:554/test

To do this, H265 should be added to codecs supported list

Code Block
themeRDark
codecs=opus,alaw,ulaw,g729,speex16,g722,mpeg4-generic,telephone-event,h264,vp8,flv,mpv,h265

and to exclusion lists

Code Block
themeRDark
codecs_exclude_sip=mpeg4-generic,flv,mpv,h265
codecs_exclude_sip_rtmp=opus,g729,g722,mpeg4-generic,vp8,mpv,h265
codecs_exclude_sfu=alaw,ulaw,g729,speex16,g722,mpeg4-generic,telephone-event,flv,mpv,h265
Warning

H265 stream will be transcoded to H264 or VP8 to play from server!

RTSP port setup

TCP port 554 is used by default to publish RTP stream via RTSP

Code Block
themeRDark
rtsp.port=554

However, the port is privileged and is available to listen to applications launched by root only. If WCS is starting from flashphoner user (the default launch mode), the port should be changed, for example

Code Block
themeRDark
rtsp.port=5554
