2. Add Recording source code
   RecordingProperties properties = new RecordingProperties.Builder() .outputMode(Recording.OutputMode.INDIVIDUAL) .hasAudio(false) .hasVideo(true) .ignoreFailedStreams(true) .resolution("1920x1080").build(); OV.startRecording(this.session.getSessionId(), properties);

INDIVIDUAL recordings of RTSP IP cameras is working fine. Try this:

Run OpenVidu with recording mode enabled:

docker run -p 4443:4443 --rm -e OPENVIDU_RECORDING=true -e OPENVIDU_RECORDING_PATH=/opt/openvidu/recordings -v /var/run/docker.sock:/var/run/docker.sock -v /opt/openvidu/recordings:/opt/openvidu/recordings openvidu/openvidu-dev:2.27.0

Clone openvidu-ipcameras tutorial:

git clone https://github.com/OpenVidu/openvidu-tutorials.git -b v2.27.0
cd openvidu-tutorials/openvidu-ipcameras

Modify the openvidu-ipcameras tutorial adding these lines to MyRestController.java file just before line 144:

RecordingProperties properties = new RecordingProperties.Builder().outputMode(Recording.OutputMode.INDIVIDUAL).hasAudio(false).hasVideo(true).ignoreFailedStreams(true).resolution("1920x1080").build();
OV.startRecording(this.session.getSessionId(), properties);

Run the openvidu-ipcameras tutorial:

mvn package exec:java

Go to https://localhost:8080/ and subscribe to the IP cameras. After they are visible in the browser, the recording will start. You can stop the Recording or close the Session with REST API. You will find at path /opt/openvidu/recordings/ the ZIP file of the INDIVIDUAL recording with the 3 webm files of the 3 IP cameras of the app.
