Unity achieve VideoPalyer controls operation of the local video

A build-based video display UI (wherein the time bar, the volume of the progress bar, and the UI may display the text corresponding to not set up)

Note: in order to achieve the mouse into a progress bar, volume and time control, you need to add the video display control RawImage BoxCollider 2D collision body and the collision body can adjust the size of the area you want triggered. 

Second, the video control script writing

Third, the use

 ① the playback device control script (Ctrl_VideosOperation.cs) added to the video display components (I am here is: Image_Videos (3))

② Create a new empty object (named: _TestVideosOperation) video operations as a test script mount object (Test_VideosOpreation.cs)

③ Test script mount operation of the video object (Test_VideosOpreation.cs) as follows:
