Then play output.mp4.file:

Room multiple streams recording to one file with subsequent mixing (WCS 5.2.1012, WebSDK 2.0.190 and newer)

Since WCS build 5.2.1012 and WebSDK build 2.0.190 it is possible to record all the room streams to one file, with automatic mixing after finishing a conference. To do this, a first participant should set room record option while creating a room:

    connection.join({
        name: getRoomName(),
        record: true
    }).on(ROOM_EVENT.STATE, function(room){
        ...
    });

In thei case, all the room streams will be reocrded to one file. When the last participant leaves the room, the recording will be stopped, and the script set in the following parameter will be automatically launched

on_multiple_record_hook_script=on_multiple_record_hook.sh

The script will mix multiple streams recorded acoording to mixer settings defined in /usr/local/FlashphonerWebCallServer/conf/offline_mixer.json file, by default

{
  "hasVideo": "true",
  "hasAudio": "true",
  "mixerDisplayStreamName": true
}
