linux下fms2流媒體伺服器搭建之六—–線上視頻錄製篇

   　視頻錄製的源碼好像網上有很多，在此聲明，我這個也是抄別人的然後改改最佳化了一下，有點累，不多說了，直接貼源碼吧：

var server_uri:String = "rtmp://215.102.25.XX/gdrc/video";
//FMS地址;跟播放器那邊設定一樣

var videoName:String = "record";//錄製的檔案名稱，可以通過參數傳遞

var my_nc:NetConnection = new NetConnection ();
//建立一個連線物件,用來串連FMS;

my_nc.connect (server_uri);
//串連FMS;

var my_ns:NetStream = new NetStream (my_nc);
//建立流,用來捕獲和播放視頻;

var my_cam:Camera = Camera.get ();
video_r.attachVideo (my_cam);
//獲得懾像頭,並將網路攝影機擷取的視頻載入到video_r裡.

//my_cam.setQuality (1024, 90);
//設定頻寬和品質;

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

my_ns.attachVideo (my_cam);
my_ns.attachAudio (my_mic);
//將網路攝影機圖象和MIC聲音裝載到流.

video_p._visible = false;
//將播放視窗設定為不可見.

//預設上網方式為adsl，這個設定需要在伺服器端的main.asc添加一些代碼，最後補上
updateBandwidth(2);

function updateBandwidth(b) {
 if ( b == 1 ) { //modem上網方式設定
  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上網方式設定
  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專線上網方式設定
  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);
}
/*本來做好了幾個按鈕可以讓使用者自己選擇上網方式，但是實在太醜了就取消了，可以自行添加

 updateBandwidth(1);

伺服器端main.asc添加後的完整內容：

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 );
    }
  }; 
};
