我在播放 red5 发布的流中录制的媒体文件时遇到问题，以下是我的代码。我可以看到创建了一个名为 out.flv 的文件，但是这个 out.flv 无法播放。

file.createNewFile();
}

System.out.printf("onStreamEvent: %s\n", notify);

String code = (String) map.get("code");
System.out.printf("<:%s\n", code);
if (StatusCodes.NS_PLAY_STREAMNOTFOUND.equals(code)) {
System.out.println("Requested stream was not found");
client.disconnect();
}
else if (StatusCodes.NS_PLAY_UNPUBLISHNOTIFY.equals(code)
|| StatusCodes.NS_PLAY_COMPLETE.equals(code)) {
System.out.println("Source has stopped publishing or play is complete");
client.disconnect();
}
}
});
client.setConnectionClosedHandler(new Runnable() {
public void run() {
if (writer != null) {
writer.close();
}
System.out.println("Source connection has been closed, proxy will be stopped");
System.exit(0);
}
});
client.setExceptionHandler(new ClientExceptionHandler() {
@Override

throwable.printStackTrace();
System.exit(1);
}
});
// connect the consumer
Map<String, Object> defParams = client.makeDefaultConnectionParams(sourceHost, sourcePort,
sourceApp);
// add pageurl and swfurl
defParams.put("pageUrl", "");
defParams.put("swfUrl", "app:/Red5-StreamRelay.swf");
// indicate for the handshake to generate swf verification data
client.setSwfVerification(true);

client.disconnect();
//proxy.stop();
}
else if ("NetConnection.Connect.Success".equals(code)) {

System.out.println("Red5ClientTest.main()");
}
else {

}
}
});
// keep sleeping main thread while the proxy runs

else {

}
我在这里可能做错了什么？
最佳答案
