Deployment Tips

• YouTube movie URLs are not playable in the Movie Player. To play a YouTube video, you need to obtain a copy of the Flash video file. There are a number of utilities available which can do this.
• The webcam and panorama viewers only support Axis webcams. They do not work with other webcams.
• The frame rate only controls how frequently frames are displayed by the video application. The webcam and panorama viewers retrieve frames from the webcam at a fixed rate of 10 frames per second. Lowering the frame rate will not change the frame retrieval rate or reduce bandwidth utilization.
• For best performance set the preferred width and height to the same size as the video and scale the viewer using the pixelScale attribute. If you set the preferred sizes larger than the frame size, the frames will be scaled in software. This is cpu intensive and will reduce Wonderland performance.

Topics

There are three versions of the Video Player:

• a movie player
• a webcam viewer
• a panorama application for pan, tilt, zoom cameras

Movie Player

The movie player supports playback of recorded movies. For details of the supported movie formats, refer to:

• http://java.sun.com/products/java-media/jmf/2.1.1/formats.html
• http://ffmpeg.mplayerhq.hu

Quicktime (MPEG-4), Flash Video (used by YouTube) and H.264 are among the popular supported formats.

Webcam Viewer

Panorama Viewer

Installing the Video Player

There are three example property files:

1. Video-movie-wlc.xml
   This property file configures the application as a Movie Player.

2. Video-webcam-wlc.xml
   Configures the application as a Webcam Viewer.

3. Panoramic-video-wlc.xml
   This property file shows how to configure the application as a Panorama Viewer.

To install the video player, copy one of these WFS property files to the WFS directory on your Wonderland server. For example, to install the Movie Player in the default Wonderland MPK20 world, copy Video-movie-wlc.xml to lg3d-wonderland/src/worlds/default-wfs/building-wld/ConferenceRoom-wld. Note that the property file sets the position of the movie player to the far wall of the conference room.

• Video-movie-wlc.xml
  This property file gives an example of how to load the video application in movie mode in Wonderland.

• Video-movie-wlc.xml
  This property file shows how to configure the video application to display a panoramic view with an Axis 212 PTZ camera.

• webcam mode

1. The movie player supports quite a wide range of formats. It's based on the Java Media Framework, and uses the ffmeg native codec library. For more details on supported formats, refer to the following:
   • http://java.sun.com/products/java-media/jmf/2.1.1/formats.html
   • http://ffmpeg.mplayerhq.hu
2. The webcam and panorama features currently support a specific type of Axis webcam, the Axis 212 PTZ:
   • http://www.axis.com/products/cam_212/index.htm
     This is a high quality pan, tilt, zoom camera with a wide-angle 3 megapixel sensor. We'd like to broaden the webcam support in the future to include more common webcams.

Summary

Adding a Video Player to your world

The Video application is loaded into Wonderland using WFS. Sample WFS property files are provided in the wonderland-modules project on java.net:

https://wonderland-modules.dev.java.net/source/browse/wonderland-modules/trunk/src/modules/apps/2d/video/

There are two example property files:

Video-movie-wlc.xml

This property file gives an example of how to load the video application in movie mode in Wonderland.

Panoramic-Video-wlc.xml

This property file shows how to configure the video application to display a panoramic view with an Axis 212 PTZ camera. The application has two modes:

• video mode
• panorama mode

In video mode, live video is displayed full-screen in the application window. In panorama mode, a static panorama mosaic is displayed and the live video view can be moved around the panorama. As the live view is moved, it updates the area of the panorama underneath. To enable panorama mode, set the 'panoramic' property to 'true' in the WFS property file.

To install the video player, copy one of these WFS property files to the WFS directory on your Wonderland server. For example, to install the movie player in the default Wonderland MPK20 world, copy Video-movie-wlc.xml to lg3d-wonderland/src/worlds/default-wfs/building-wld/ConferenceRoom-wld. Note that the property file specifies the position of the movie player on the far wall of the conference room.

Next, edit the file and change the path to the video:

<void property="source">                     
    <string>file://movies/movie.mov</string>
</void>

Note: The file path must be accessible in the same directory on all systems where the Wonderland client will run.

On Windows systems, the path should have the following format:

     <string>file://C://movies/movie.mov</string>

The size of the video window is specified by the following properties:

<void property="preferredWidth">
    <double>1280</double> 
</void>
<void property="preferredHeight">
    <double>960</double>
</void>

These are preferred values; the video application will stretch the movie to fit the specified width and adjust the height to maintain the correct aspect ratio.

Once you've installed the file in the WFS directory, restart the Wonderland server, or use the Wonderland Manager application to reload WFS.

Deployment Tips

Things to be aware of when deploying the Video Player application.

Application Properties

The Video Player can be pre-configured by setting the following properties in the WFS property file:
