我最近发布了一个关于我遇到PixelType错误的问题。您可以阅读该帖子here
我认为我通过创建以下类来解决该问题。

在我的Flash客户端成功连接之后，我在服务器上调用一个名为helloXuggler（）的方法，该方法在我的主应用程序文件中看起来像这样。
public static void helloXuggler()
{
String sourceUrl = "rtsp://10.0.1.68:8554/CH001.sdp?AuthMode=Web&AuthValue=6049";
String destinationUrl = "./webapps/AEWings/streams/xuggler.flv";
//this.convertVideo = new ConvertVideo(sourceURL, destinationURL);
System.out.printf("transcode %s -> %s\n", sourceUrl, destinationUrl);
ConvertVideo converter = new ConvertVideo(sourceUrl, destinationUrl);
converter.run();
// read packets from the source file, which dispatch events to the
// writer, this will continue until
}
一切似乎进展顺利，一切都连接起来，方法被调用但是大约30秒后我得到了下面的堆栈跟踪，我不知道该怎么办。
