Observe Live with MediaRecorder
Procedure in Short
The detailed procedure is present in the chapter MediaRecorder with The Observer XT in the MediaRecorder Reference Manual. Press F1 in MediaRecorder to open the Reference Manual.
In The Observer XT
- Choose File > Preferences > N-Linx Settings.
- Select Use N-Linx Server to connect with other applications.
- In the N-Linx Server address field, enter the computer name of the computer with N-Linx Server. If N-Linx Server is on the same computer as The Observer XT, leave the default entry Localhost.
- In the N-Linx Server port field, leave the default port 5672. Ask your system administrator for assistance if this port is used by another program. If you change the port number, enter the same number in the N-Linx connection settings in MediaRecorder. Also, create exceptions in Windows Firewall for this port on all computers with MediaRecorder, The Observer XT, and N-Linx Server. See the MediaRecorder Help for details.
- Click Test Connection. If connection with N-Linx is found, the Status will change to Connected. If not, enter the correct settings and click Test Connection again.
- Click OK.
- Choose Setup > Project Setup.
- Under Observation Source, select Live Observation. The Devices window now opens. If not, click the Devices button.
- Select the checkbox in front of MediaRecorder [version number - computer name] and click Edit Settings. This opens MediaRecorder when it is not already open.
- Click Edit Settings again. A window with the available MediaRecorder configuration files now opens. Select the configuration file you want to use and click OK. If you do not select a configuration, Current Settings.mrs will be used.
- Enter a name in the Identify Device As field. This allows you to control multiple MediaRecorders on different computers with The Observer XT.
In MediaRecorder
- Choose File > Preferences > N-Linx Settings.
- Select Allow Communication with N-Linx Server.
- In the N-Linx Server address field, leave the default value Localhost if MediaRecorder runs on the same computer as N-Linx Server. If both programs are on different computers, enter the IP address or computer name of the computer with N-Linx Server.
- In the N-Linx Server port field, leave the default port 5672. Ask your system administrator for assistance if this port is used by another program.
- When the connection with N-Linx Server is established, the Status will be Connected. Click OK.
- If MediaRecorder and The Observer XT run on different computers, select the mapped drive as the location to store the video files. For example, if you mapped the default folder C:\Users\Public Documents\Noldus\MediaRecorder\Video files as X:\, set the default video file location to X:\ and not to the original folder. The original folder is locally on the computer with MediaRecorder and cannot be accessed by The Observer XT.
Carry Out Observation
When you create a new observation, MediaRecorder opens if it is not already open. When you carry out an observation, MediaRecorder starts video recording. When you stop an observation, video recording stops. The videos are automatically linked to the observation and synchronized with the events.
Note: If MediaRecorder is not open, the MediaRecorder line in the Devices window is grayed out and the status is Disabled. MediaRecorder will be started when you create an observation.
