Detailed Description

video-timline controller and display

The video-timeline can be displayed in a canvas-group. Given a filename it queries the video-server about file-information and creates VideoImageFrame as neccesary (which query the server for image-data).

This class contains the algorithm to position the single frames on the timeline according to current-zoom level and video-file attributes. see update_video_timeline()

The VideoTimeLine class includes functionality to launch a video-monitor corresponding to its currently diplayed file.
