Detailed Description
A singleton manager class for playing videos.
A vector of images with enclosing image and easy2D tableaux is cached so that computed overlays such as Harris corners can be played back quickly. The cache option can be turned off if one is going to just play the video and not apply image segmentation processing to the frames.
A demo of overlaying points on the video is provide by ::easy2D_demo to get rid of the points, reload the video
It is planned to extend the class to handle multiple panes (grid locations) so that different (or the same) videos can be playing simultaneously in different zoom states as well as pause states. This extension will the state variables to be changed to vectors as well as having multiple caches.. etc.
Known problems:
- quiting while the video is paused can cause a seg fault since the movie gets deleted before the loop quits
- There is a continuous gl error stream from vgui_adaptor. Something to do with "setting draw buffer to back"
