flash - 有人遇到这个错误吗？ RTMP 流媒体视频提前 3-4 秒结束？

Question

我过去曾为使用他们的 LimeLight 服务器流式传输视频的客户创建了一个播放器，之前没有遇到过问题，但是对于使用不同 LimeLight 服务器的新客户，视频似乎也以 3-4 秒结束早。

我在 3 个截然不同的视频上测试过的痕迹:

metadata duration = 32        // 32 secs long, ends at 27
Stop [27.350 seconds] = 4.65 

metadata duration = 17        // 17 secs long, ends at 12
Stop [12.852 seconds] = 4.148

metadata duration = 258       // 258 secs long, ends at 255
Stop [255.861 seconds]

在视频播放器中，我检查了 NetStream.Play.Stop，然后在其中放置了一个“重置”类型的函数。然而，由于这个奇怪的错误，这个函数触发得太早了。 有没有人以前见过这个？

private function netStatusHandler(event:NetStatusEvent):void 
    {
        trace("connected is: " + nc.connected );

        switch (event.info.code) 
        {
            case "NetConnection.Connect.Success":
                trace("Connected");
                connectStream();
                break;

            case "NetStream.Play.Start":
                trace("********** Start [" + ns.time.toFixed(3) + " seconds]");
            break;

            case "NetStream.Play.Stop":
                trace("‹ ----------- Playback has stopped. ----------- ›");
                trace("Stop [" + ns.time.toFixed(3) + " seconds]");
                if (nsBuffering){ removeChild(bufferAni); }
                nsBuffering = false;
                videoStatus = "NotPlaying";
                resetVideo(); //<- Video ends so go back to start
                // ^ This triggers too early
            break;
        }
    }

我看到的唯一解决方法是保存我从元数据持续时间获得的初始数字，并运行一个计时器来不断检查当前 ns.time 何时匹配元数据，然后运行我的重置函数。

我找到了解决方案!

我必须先在网络流命中 play.stop 时进行检查，然后在缓冲区为空时调用我的重置函数...

网站上的代码是AS2，但我把它转换成了AS3:

.

private function netStatusHandler(event:NetStatusEvent):void 
    {
        trace("connected is: " + nc.connected );

        switch (event.info.code) 
        {
            case "NetConnection.Connect.Success":
                trace("Connected");
                connectStream();
                break;

            case "NetStream.Buffer.Empty":
                trace("‹ ----------- Buffer is Empty! ----------- ›");
                if (nsBuffering){ removeChild(bufferAni); }
                nsBuffering = false;

                if (videoFinished) // < Now I can run my reset
                {
                    resetVideo();
                    videoFinished = false;
                }

            break;

            case "NetStream.Buffer.Full":
                trace("‹ ----------- Buffer is FULL! ----------- ›");
                if (nsBuffering){ removeChild(bufferAni); }
                nsBuffering = false;
            break;

            case "NetStream.Buffer.Flush":
                trace("Data has finished streaming, remaining buffer will be emptied.");
                videoStatus = "NotPlaying";
            break;

            case "NetStream.Play.Stop":
                trace("‹ ----------- Playback has stopped. ----------- ›");

                videoFinished = true; // < This first
            break;
        }
    }
