[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);

}

/*本来做好了几个按钮可以让用户自己选择上网方式，但是实在太丑了就取消了，可以自行添加

Modem_btn.onPress = function() {

updateBandwidth(1);

}

DSL_btn.onPress = function() {

updateBandwidth(2);

}

LAN_btn.onPress = function() {

updateBandwidth(3);

}

my_nc.onStatus = function (thisObj:Object)

{

//trace (thisObj.code);

if (thisObj.code == "NetConnection.Connect.Success")

{

RecordStop ("空闲中");

}

else

{

trace ("错误:服务器未启动或URI输入错误.");

function Record ()

my_ns.publish (videoName, "record");

}

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 );

}

};

};
