Play a specified video using EMGUCV

Use Capture to load a video.
Use the Getcaptureproperty function to get the various properties of this video.
Then use Application.idle to continuously display the frame in the video (showing a frame, the program enters the idle, continues to load the next frame)
Because there are too many frames in the video, the. NET garbage collection mechanism will not catch up, use Gc.collect (), to force garbage collection, you can reduce the memory consumption of the program from 700MB to about 100MB
