Describe the feature

I'm writing a video call server in C++ that allows video calls, and I want to save the video. How can I do that?
Note: I'm testing the program on a virtual machine ubuntu server that doesn't have a webcam.

    virtual void onCallMediaState(OnCallMediaStateParam& params)
   {
       CallInfo callInfo = getInfo();
       for (unsigned media_index = 0; media_index < callInfo.media.size(); media_index++)
       {
           if (callInfo.media[media_index].type == PJMEDIA_TYPE_AUDIO)
           {
               AudioMedia audioMedia = getAudioMedia(media_index);
               saveAudioMedia(audioMedia, media_index);
           }
           if (callInfo.media[media_index].type == PJMEDIA_TYPE_VIDEO)
           {
              // Error
               VideoMedia videoMedia = getEncodingVideoMedia(media_index);
           }
       }
   }

And I got this error:

call.cpp  .....getEncodingVideoMedia() error: no encoding slot (recvonly?) (status=70004) [../src/pjsua2/call.cpp:630]
  1. What should I do to be able to save a video call on a server that doesn't have a webcam?
  2. How can I save a video call?

You need to implement the video recorder yourself.
Check avi_player for video player implementation, now you need to do something similar for recording.
Check also wav_writer which does the same but for audio.
