Your Server can receive video along with system and microphone audio from a remote Client with the FFmpeg driver over RTSP. To do it, follow the steps below:

1. On the Server:
   1. Open the port for receiving data from the remote Client

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

      listenrtsp://<Server IP-address>:<Port>/<RTSP-link>

      

      RTSP link may be omitted.

      
      

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. Execute the following command:

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