WOWZA到IOS-如何直播流

到目前为止，我几乎为IOS开发了一款Flash Air应用程序，完成了50%。我使用RED5媒体服务器获得了所有的实时流媒体，但当我发现iPhone摄像头显示90度时，我就陷入了死胡同，因此发送并保存到RED5服务器的流也被记录为90度。我在网上读了很多关于堆栈溢出的文章，说这是一个已知的Bug。不确定何时会修复此问题。我还尝试了一些可以在我的Air应用程序中实现相机旋转的ANE Air原生扩展，这些是DiaDraw和StarlingCamera ANE，但在网上找不到任何信息教程，因此无法实现

Flash Adobe Air for IOS代码，连接到RED5服务器并显示iPhone摄像头为90度：

import flash.display.DisplayObject;
import flash.display.Sprite;
import flash.display.StageAlign;
import flash.display.StageScaleMode;

 var nc:NetConnection;

 var nsIn:NetStream;




        // support autoOrients
        stage.align = StageAlign.TOP_LEFT;
        stage.scaleMode = StageScaleMode.NO_SCALE;
        cam = Camera.getCamera();
        cam.setMode(320, 300, 25); 
        cam.setQuality(0,100);
        if (!cam) 
        {
            txt.text ="No camera is installed.";
        }
        else 
        {

            nc = new NetConnection(); 
            nc.connect("rtmp://192.168.1.5/RED5Hugt");
            nc.addEventListener(NetStatusEvent.NET_STATUS,getStream);     
            nc.client = this;


            //connectCamera();
        }

    function getStream(e:NetStatusEvent):void
    {

        connectCamera();
        nsIn = new NetStream(nc); 
        nsOut = new NetStream(nc); 

        vid.attachNetStream(nsIn);
        nsIn.play("tester");

         nsOut=new NetStream(nc);
         netOut.attachAudio(mic);
         nsOut.attachCamera(cam);
         nsOut.publish("tester", "live");


    // add click event to record button
    // add event for stage video render state
    }

     function connectCamera():void 
    {
        vid             = new Video();
        vid.width       = cam.width;
        vid.height      = cam.height; 
        vid.x = 0;
        vid.y = 0;
        vid.attachCamera(cam);
        addChild(vid);    

        //stage.addEventListener(MouseEvent.CLICK, clickHandler);
    }

     function clickHandler(e:MouseEvent):void 
    {

        return;

        switch (cam.width) {
            case 160:
                cam.setMode(320, 240, 10); 
                break;
            case 320:
                cam.setMode(640, 480, 5); 
                break;
            default:
                cam.setMode(160, 120, 15); 
                break;
        } 
        removeChild(vid);           
        connectCamera();
    }

于是我决定以本机方式进行流式传输，我使用objective-c中的媒体和CommLib库找到了这段代码，我将其粘贴到了Pastebin上，因为粘贴到这里时有太多的代码需要编辑：

这是成功连接到另一台PC上运行的RED5 Java应用程序适配器的RTMP客户端

当使用Xcode运行RTMP客户端时，应用程序正在进行流媒体直播，但每隔几秒钟音频就会出现故障，我无法找到任何可以解决此问题的方法，可能我需要更改一些代码，但我在线找到了此RTMP客户端代码，并修改了流名称和RTMP Url，以指向我在RED5服务器上的应用程序

为什么音频一直有问题。所以现在我想试试WOWZA媒体服务器

到目前为止，我下载了Wowza媒体服务器，然后安装了Eclipse。安装Eclipse之后，我安装了Wowza IDE，我在Eclipse中安装了该IDE，但请确保在安装Wowza IDE之前先安装Wowza媒体服务器

然后我在网上找到了一些代码，可能是在Wowza服务器上运行的服务器，新的Wowza服务器是在浏览器中运行的，我尝试在终端上运行此代码，但无法运行，因为它在终端上一直说“操作无法运行”

这是我用于服务器的代码：

package com;

import com.wowza.wms.application.*;
import com.wowza.wms.amf.*;
import com.wowza.wms.client.*;
import com.wowza.wms.module.*;
import com.wowza.wms.request.*;
import com.wowza.wms.stream.*;
import com.wowza.wms.rtp.model.*;
import com.wowza.wms.httpstreamer.model.*;
import com.wowza.wms.httpstreamer.cupertinostreaming.httpstreamer.*;
import com.wowza.wms.httpstreamer.smoothstreaming.httpstreamer.*;

public class RED5Hugt extends ModuleBase {

public void doSomething(IClient client, RequestFunction function,
        AMFDataList params) {
    getLogger().info("doSomething");
    sendResult(client, params, "Hello Wowza");
}

public void onAppStart(IApplicationInstance appInstance) {
    String fullname = appInstance.getApplication().getName() + "/"
            + appInstance.getName();
    getLogger().info("onAppStart: " + fullname);
}

public void onAppStop(IApplicationInstance appInstance) {
    String fullname = appInstance.getApplication().getName() + "/"
            + appInstance.getName();
    getLogger().info("onAppStop: " + fullname);
}

public void onConnect(IClient client, RequestFunction function,
        AMFDataList params) {
    getLogger().info("onConnect: " + client.getClientId());
}

public void onConnectAccept(IClient client) {
    getLogger().info("onConnectAccept: " + client.getClientId());
}

public void onConnectReject(IClient client) {
    getLogger().info("onConnectReject: " + client.getClientId());
}

public void onDisconnect(IClient client) {
    getLogger().info("onDisconnect: " + client.getClientId());
}

public void onStreamCreate(IMediaStream stream) {
    getLogger().info("onStreamCreate: " + stream.getSrc());
}

public void onStreamDestroy(IMediaStream stream) {
    getLogger().info("onStreamDestroy: " + stream.getSrc());
}

}

所以现在我运行Xcode项目RTMP客户机，发现RTMP客户机确实连接了，但没有实时流。我只是想问我需要在哪里修改代码才能让流媒体直播正常工作

另外，根据我使用AdobeAIR for IOS和使用RED5的经验，我是否应该选择这最后一条路线，因为我不确定。我做了很多研究，我真的很想找到一种免费的方式来了解如何从IPhone摄像头中播放流媒体。我试过AdobeForiOS到RED5服务器，发现有一个已知的Bug，我试过RED5的原生版本，发现了音频故障，那么Wowza是最好的选择吗

更新 我在Xcode控制台中得到一个无法找到流的输出，以下是输出：

2014-07-30 13:33:06.246 RTMPStreamComeback[340:4003]  $$$$$$ <MPIMediaStreamEvent> stateChangedEvent: sender = MediaStreamPlayer, 4 = NetStream.Play.StreamNotFound

但是，就像RED5一样，音频似乎出现了故障，但除了音频，流从未中断

我怎样才能解决这个问题

这是来自Xcode的跟踪：

还建议：

Currently the library does not provide an instrument to control the stream quality. This is planned for a future release.

因此，我认为这不可能改变音频流格式

我认为问题可能在于所选的音频编解码器；如果你有能力改变一个选择，我建议尝试mp3在44100kHzThanks Mondain我现在看看

Audio:
codec - Nelly Mozer 16KHz, mono
bitrate - 128000

Video:
codec - H.263 (Sorenson)
bitrate - 200000
resolution - 192x144px
fps = 25
intra frame - 10

Currently the library does not provide an instrument to control the stream quality. This is planned for a future release.
