Question

我正试图从RTMP视频中获取视频帧。视频播放得很好，我可以在我的视频表面上看到它，但我无法抓住它到位图，位图是黑色.. :( 我需要使用 ActionScript 2 。

有什么想法吗？

这是我的代码：

import flash.media.Video;
import flash.net.*;
import flash.display.*;
import flash.geom.Rectangle;
import flash.geom.Point;
import flash.display.*;

var i = 0;
var kVIDEOW = 720;
var kVIDEOH = 576;
var vidBmpHolder:BitmapData;
var vidBmpDisplay:BitmapData;
var vidBmp = createEmptyMovieClip("bmp", 0);
var vidBmpRect:Rectangle;
var vidBmpPoint:Point;

var connection_nc:NetConnection = new NetConnection();
connection_nc.connect("rtmp://tvserver.chaneladd.tv:1935/live");
var stream:NetStream = new NetStream(connection_nc);


vidBmpHolder = new BitmapData(kVIDEOW, kVIDEOH, false, 0x000000);
vidBmpDisplay = new BitmapData(kVIDEOW, kVIDEOH, false, 0x000000);
vidBmpRect = new Rectangle(0, 0, kVIDEOW, kVIDEOH);
vidBmpPoint = new Point(0, 0);
// Create the Bitmap display object
vidBmp.attachBitmap(vidBmpDisplay,0);
vidBmp.x = 0;
vidBmp.y = 0;

if (stream) 
{
    video.my_video.attachVideo(stream);
    stream.play("437.stream");

    onEnterFrame = function ()
    {
        video.my_video.attachVideo(null);
        vidBmpHolder.draw(video);
        video.my_video.attachVideo(stream);
        vidBmp.attachBitmap(vidBmpHolder,0);
        addChild(vidBmp);
    };
}
else
{
    trace("not connected");
}

简而言之，它无法完成，因为它违反了安全限制。解释它的文件在第49页：http://wwwimages.adobe.com/www.adobe.com/content/dam/Adobe/en/devnet/flashplayer/pdfs/flash_player_10_security.pdf
