I'm working with video in Flex. I'd like to be able to pause the video at a certain point and copy the displayed frame as an image, and save it to a database. I'm wondering if anybody knows how I might copy a single frame from a paused video? Thanks --Matt

推荐答案

假设您的视频被称为剪辑

Assuming your video is called 'clip'

var frameGrab:BitmapData = new BitmapData( clip.width, clip.height, false, 0x000000);
frameGrab.draw(clip); // < the .draw() method will copy the frame from your video.

// Add to the stage...
var frame:Bitmap = new Bitmap(frameGrab);
addChild(frame);
