[转]linux下的fms2流媒体服务器搭建六部曲之六在线视频录制篇

   　视频录制的源码好像网上有很多，在此声明，我这个也是抄别人的然后改改优化了一下，有点累，不多说了，直接贴源码吧：

var server_uri:String = "rtmp://215.102.25.XX/gdrc/video";
//FMS地址;跟播放器那边设置一样

var videoName:String = "record";//录制的文件名，可以通过参数传递

var my_nc:NetConnection = new NetConnection ();
//新建一个连接对象,用来连接FMS;

my_nc.connect (server_uri);
//连接FMS;

var my_ns:NetStream = new NetStream (my_nc);
//新建流,用来捕获和播放视频;

var my_cam:Camera = Camera.get ();
video_r.attachVideo (my_cam);
//获得慑像头,并将摄像头获取的视频载入到video_r里.

//my_cam.setQuality (1024, 90);
//设置带宽和质量;

var my_mic:Microphone = Microphone.get ();
//获得MIC;

my_ns.attachVideo (my_cam);
my_ns.attachAudio (my_mic);
//将摄像头图象和MIC声音装载到流.

video_p._visible = false;
//将播放窗口设置为不可见.

//默认上网方式为adsl，这个设置需要在服务器端的main.asc添加一些代码，最后补上
updateBandwidth(2);

function updateBandwidth(b) {
 if ( b == 1 ) { //modem上网方式设置
  my_cam.setMode(160,120,2);0
  my_cam.setQuality(0, 75);
  my_cam.setKeyFrameInterval(3);
  my_mic.setRate(5);
  video_r._height = 100;
  video_r._width = 150;
 }
 else if ( b == 2 ) { //adsl上网方式设置
  my_cam.setMode(160,120,5);
  my_cam.setQuality(0, 85);
  my_cam.setKeyFrameInterval(5);
  my_mic.setRate(11);
  video_r._height = 130;
  video_r._width = 175;
 }
 else { //LAN专线上网方式设置
  my_cam.setMode(160,120,15);
  my_cam.setQuality(0, 90);
  my_cam.setKeyFrameInterval(10);
  my_mic.setRate(22);
  video_r._height = 150;
  video_r._width = 200;
 }
 my_ns.call('setBandwidth', 0, b);
}

服务器端main.asc添加后的完整内容：

load("components.asc");

application.onAppStart = function() {};
application.onConnect = function(client) {
 application.acceptConnection(client);
 client.getFileLength = function(filename) {
  var tlen = Stream.length(filename);
  return tlen;
 };
 
 Client.prototype.setBandwidth = function(bw) {
   if ( bw == 1 ) { // modem settings
  this.setBandwidthLimit( 35000/8, 22000/8 );
   }
   else if ( bw == 2 ) { // DSL settings
   this.setBandwidthLimit( 800000/8, 100000/8 );
    }
    else { // LAN settings
   this.setBandwidthLimit( 400000, 400000 );
    }
  }; 
};
