      Info
      title Note
      The open port mustn’t be occupied. You can use the following command to check if the port is available:  Code Block netstat -ano | findstr :<Port> It is recommended to set ports higher than 10000.

      
      

   2. Add a 1 channel device and specify its address in the IP address field in the following format:

      Code Block
      listenrtsp://<Server IP address>:<Port>

      

      Info
      title Note
      The RTSP link is specified optionally. Code Block listenrtsp://<Server IP address>:<Port>/<RTSP link> For example: Code Block listenrtsp://127.0.0.1:1554/live1.sdp where 127.0.0.1—IP address of the Server; 1554—RTSP port, which mustn’t be occupied. To check if the port is available, you can use the command from step 1a; live1.sdp—RTSP link.

      
      

2. On the remote Client:
   1. Download the package of open source FFmpeg libraries from the official website.
   2. Open the command prompt, and go to the folder containing the ffmpeg.exe file.

   3. Run the following command:

      Code Block
      ffmpeg.exe -f gdigrab -video_size 640x480 -i desktop -c:v <Codec> -f rtsp -muxdelay 0.1 "listenrtsp://<Server IP address>:<Port>/<RTSP link>"

      where 
      – the Codec parameter may take accept the mpeg2video, mpeg4, h264 or hevc value;
      – the video_size 640x480 and -muxdelay 0.1 parameters may be omitted or altered.
      If necessary, you may can specify additional parameters in this command.

      title Note
      The axes of the capture area are offset from the upper left corner of the main monitor. If the additional monitor is located to the left of the main monitor, a negative value of offset_x must be used to move the capture area to the additional monitor. If the additional monitor is located above the main monitor, a negative value of offset_y must be used to move the capture area to the additional monitor.
