OSMF如何獲取屏幕截圖

Question

在這樣的普通屏幕截圖中：bitmapData.draw（video，new Matrix（））; 但是如何在osmf播放器中獲取視頻對象？ 我嘗試在空白圖像中繪制mediaPlayerSprite結果

var pictureData:BitmapData = new BitmapData(width, height); 
var x:DisplayObjectTrait = _mediaPlayer.media.getTrait(org.osmf.traits.MediaTraitType.DISPLAY_OBJECT) as DisplayObjectTrait; 
var y:Video = x.displayObject as Video; 
pictureData.draw(m_container, new Matrix());  
var byteArray:ByteArray = new JPEGEncoder(80).encode(pictureData);  
var file:FileReference = new FileReference();  
file.save(byteArray, "pic.jpeg");

Answer 1

要從視頻中獲取位圖數據，請執行以下操作：

var videoDisplay:VideoDisplay = video.videoDisplay;
var videoObject:Video = videoDisplay.videoObject;
var bitmapData:BitmapData = new BitmapData(videoObject.videoWidth, videoObject.videoHeight, true, 0x000000);
