How to extract a point cloud from Kinect recorded videos (.oni files)

Question

Hi there,

When a live Kinect is connected, launching openni with roslaunch openni_launch openni.launch starts publishing point clouds at topic /camera/depth/points.

I have videos recorded from Kinect in OpenNI file format (.oni). Can I extract point clouds from these videos? Is there is away openni.launch can be executed with these videos or without live camera?

Thanks.
