WOWZA到IOS – 如何生活stream

到目前为止，我几乎开发了一个闪存空气IOS应用程序，我已经完成了50％。 我得到了所有现场stream媒体与RED5媒体服务器的工作，但当我发现iPhone摄像头正在显示90度，所以stream被发送并保存到RED5服务器也被logging90度来到死胡同。 我甚至在Stack Overflow上在线阅读了很多文章，这是一个已知的Bug。 不知道什么时候这将被修复。 我也尝试了一些ANE Air原生扩展，这将在我的Air App中工作相机旋转，这些是DiaDraw和StarlingCamera ANE，但无法在网上find任何信息教程，所以无法使其工作。

Flash的Adobe AIR的IOS代码连接到RED5服务器，并显示达到iPhone摄像头是90度：

import flash.display.DisplayObject; import flash.display.Sprite; import flash.display.StageAlign; import flash.display.StageScaleMode; import flash.events.ActivityEvent; import flash.events.MouseEvent; import flash.media.Camera; import flash.media.Video; import flash.events.NetStatusEvent; import flash.net.NetStream; import flash.net.NetConnection; var nc:NetConnection; var cam:Camera; var vid:Video; var nsOut:NetStream; 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(); } 

RED5服务器代码：

 package com; import java.lang.reflect.Array; import java.util.ArrayList; import java.util.Collection; import java.util.Hashtable; import org.red5.server.adapter.ApplicationAdapter; import org.red5.server.adapter.MultiThreadedApplicationAdapter; import org.red5.server.api.IClient; import org.red5.server.api.IConnection; import org.red5.server.api.Red5; import org.red5.server.api.scope.IScope; import org.red5.server.api.service.IPendingServiceCall; import org.red5.server.api.service.IPendingServiceCallback; import org.red5.server.api.service.IServiceCapableConnection; import org.red5.server.api.service.IServiceHandlerProvider; import org.red5.server.api.stream.IBroadcastStream; import org.red5.server.api.stream.IServerStream; import org.red5.server.api.stream.support.SimplePlayItem; import org.red5.server.api.stream.support.StreamUtils; import org.red5.server.stream.ClientBroadcastStream; import org.red5.server.stream.RecordingListener; import static java.lang.System.*; public class Application extends MultiThreadedApplicationAdapter{ //private static final Log log = LogFactory.getLog( Application.class ); private IBroadcastStream serverStream; @Override public boolean appStart(IScope scope) { if(!super.appStart(scope)) { return false; } else { super.appStart(scope); return true; } } @Override public void appStop(IScope scope) { } //User connecting/disconnecting to/from application @Override public boolean appConnect(IConnection connection, Object[] parameters) { super.appConnect(connection, parameters); //connection.getClient().setAttribute("userName", parameters[0]); return true; } @Override public void appDisconnect(IConnection connection) { super.appDisconnect(connection); } //User joining/leaving scope @Override public boolean appJoin(IClient client, IScope scope) { super.appJoin(client, scope); return true; } @Override public void appLeave(IClient client, IScope scope) { super.appLeave(client,scope); } public boolean connect(IConnection conn, IScope scope, Object[] params) { super.connect(conn, scope, params); return true; } } 

所以然后我决定本地stream，并且我在Objective-C中使用了Media和CommLib库，并且发现了这个代码，我把它粘贴到了Pastebin上，因为在粘贴的时候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 CLIENT。

http://pastebin.com/0KQvTL0b

当使用Xcode运行RTMP客户端时，该应用程序实时stream式传输，但是每隔几秒钟，audio就会出现故障，我找不到任何可以解决此问题的事情，也许我需要更改一些代码，但是我发现这个RTMP CLIENT代码在线，修改了Stream Name和RTMP Url以指向RED5服务器上的应用程序。

为什么audio不停地闪烁。 所以现在我想给WOWZA媒体服务器一个去。

到目前为止，我下载了Wowza Media Server，然后安装了Eclipse。 一旦安装了Eclipse，我就安装了我在Eclipse中安装的Wowza IDE，但确保在安装Wowza IDE之前先安装Wowza Media Server。

然后我发现一些在线的代码是在Wowza服务器上运行的服务器，新的Wowza服务器运行在浏览器中，我试图在terminal中运行这个代码，但不能运行，因为它一直说“操作无法运行“在terminal。

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RTMP客户端的Xcode项目，并发现RTMP客户端连接，但我没有得到实时stream。 只是想问我需要改变我的代码，以获得实时stream的工作？

还有我使用Adobe Air的IOS和使用RED5的经验，我应该采取这最后的路线，因为我不知道。 我已经研究了很多，真的想find知道如何从iPhone摄像头stream的无成本的方式。 我已经尝试了Adobe的IOS到RED5服务器，发现有一个已知的Bug，我已经尝试原生RED5，并发现audio故障所以是Wowza最好的赌注？

UPDATE

我在Xcode控制台中得到一个输出stream无法find，这里是输出：

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

我已经设置了UpStream名称“tester”和DownStream名称“tester”

更新

stream现在工作，我发现这个教程在线，发现我需要包括Application.xml和configuration文件。 这里是教程：

但是，就像RED5一样，Audio似乎也出现了问题，但是除了audio之外，audiostream不会被打乱。

我怎样才能解决这个问题？

这是Xcode的踪迹：

这些是audio和video格式的默认设置：默认stream媒体设置如下所示：

 Audio: codec - Nelly Mozer 16KHz, mono bitrate - 128000 Video: codec - H.263 (Sorenson) bitrate - 200000 resolution - 192x144px fps = 25 intra frame - 10 

还build议：

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

所以我不认为这是可以改变audiostream格式
