使用 Adob​​e Cirrus 的 netStream 状态事件问题

Question

基本上我会尝试总结一下。我有一堆潜在的随机字符串用于 recvStream.play("randomstring");

然后我有一个计时器每 5 秒检查一次运行事件侦听器的函数：

recvStream.addEventListener(NetStatusEvent.NET_STATUS,
    netConnectionHandler);

然后我在 switch 语句中思考我可以使用它来检查它是否是活动流，或者让它搜索另一个应该活动的流或停止计时器并让它播放。

    // i was thinking this would verify it's playing and then that's it
         case "NetStream.Play.Start" :
            trace("ITS PLAYING YOU SHOULD SEE SOMETHING");
            timer.stop();
                        break;

         // i was thinking i could use this to see if the string is nothing then the timer would run again
         case "NetStream.Buffer.Empty" :
            trace("THE BUFFER IS EMPTY KEEP LOOKING");
                        //code to look again
            break;

//I also tried NetStream.Play.StreamNotFound instead of NetStream.Buffer.Empty didn't work either

但事实并非如此。我应该使用其他东西来代替 NetStream.Buffer.Empty 吗？还是其他什么东西都在一起？

我在 Flash CS5 中使用 Actionscript 3，并且使用 Cirrus RTMFP http://labs.adobe.com/technologies/cirrus/

我不明白为什么当您附加了一个侦听器来告诉您流的状态时，您为什么要让计时器检查流：

recvStream.addEventListener(NetStatusEvent.NET_STATUS,
    netStatusHandler);

// some code

private function netStatusHandler (ev:NetStatusEvent) : void {

    if (ev.info.level == "error") {
        trace ("Something went wrong. Try again!");
        // call restart method here
        return;
    }

    switch (ev.info.code) {
        case "NetStream.Play.Start" :
            trace("IT'S PLAYING YOU SHOULD SEE SOMETHING");
            break;

        case "NetStream.Buffer.Empty" :
            trace("THE BUFFER IS NOW EMPTY.");
            break;

        // ... any other netstatus events you want to react upon.
    }
}

显然，您还应该考虑在您之前验证随机字符串的正确性调用recvStream.play() - 这比故意让NetStream失败更干净，并且不会造成网络压力。
