VideoBuffer Class

Defined in: VideoBuffer:41
Module: EaselJS

When an HTML video seeks, including when looping, there is an indeterminate period before a new frame is available. This can result in the video blinking or flashing when it is drawn to a canvas. The VideoBuffer class resolves this issue by drawing each frame to an off-screen canvas and preserving the prior frame during a seek.

var myBuffer = new createjs.VideoBuffer(myVideo);
var myBitmap = new Bitmap(myBuffer);
