如何在asp.net中如何在线播放各类视频文件

如何在asp.net中如何在线播放各类视频文件

一。后台拼字符串动态加载写法

前台调用代码

< html xmlns="http://www.w3.org/1999/xhtml" >

< head id="Head1" runat="server">

< /head>

< body>

< /body>

< /html>

后台调用代码

protected void Page_Load(object sender, EventArgs e)

{

this.video_content.InnerHtml = PlayMedia.Play("http://hot.tudou.com/flv/005/680/205/5680205.flv", 472,385);

}

视频播放类:

using System;

using System.Collections.Generic;

using System.Text;

namespace Common

{

public class PlayMedia

{

public PlayMedia()

{

//

// TOD 在此处添加构造函数逻辑

//

}

public static string Play(string url, int width, int height)

{

string strTmp = url.ToLower();

if (strTmp.EndsWith(".wmv") || strTmp.EndsWith(".mp3") || strTmp.EndsWith(".wma") || strTmp.EndsWith(".avi") || strTmp.EndsWith(".asf") || strTmp.EndsWith(".mpg"))

{

return wmv(url, width, height);

}

else if (strTmp.EndsWith(".mp3"))

{

return mp3(url, width, height);

}

else if (strTmp.EndsWith(".swf"))

{

return swf(url, width, height);

}

else if (strTmp.EndsWith(".flv"))

{

return flv(url, width, height);

}

else if (strTmp.EndsWith(".jpg") || strTmp.EndsWith(".gif"))

{

return img(url, width, height);

}

else if (strTmp.EndsWith(".rm"))

{

return rm(url, width, height);

}

else

{

return "视频文件数据错误";

}

}

///

/// flv格式文件播放

///

///

///

private static string flv(string url, int width, int height)

{

System.Text.StringBuilder sb = new System.Text.StringBuilder();

sb.Append("");

return sb.ToString();

}

///

/// wmv格式文件播放

///

///

///

private static string wmv(string url, int width, int height)

{

System.Text.StringBuilder sb = new System.Text.StringBuilder();

sb.Append("
\n");

return sb.ToString();

}

private static string wma(string url, int width, int height)

{

System.Text.StringBuilder sb = new System.Text.StringBuilder();

sb.Append("");

return sb.ToString();

}

///

/// avi格式文件播放

///

///

///

private static string avi(string url, int width, int height)

{

System.Text.StringBuilder sb = new System.Text.StringBuilder();

sb.Append("");

return sb.ToString();

}

private static string mpg(string url, int width, int height)

{

System.Text.StringBuilder sb = new System.Text.StringBuilder();

sb.Append("");

return sb.ToString();

}

private static string rm(string url, int width, int height)

{

System.Text.StringBuilder sb = new System.Text.StringBuilder();

sb.Append("");

return sb.ToString();

}

private static string swf(string url, int width, int height)

{

System.Text.StringBuilder sb = new System.Text.StringBuilder();

sb.Append("");

return sb.ToString();

}

private static string mp3(string url, int width, int height)

{

System.Text.StringBuilder sb = new System.Text.StringBuilder();

sb.Append("");

return sb.ToString();

}

private static string img(string url, int width, int height)

{

System.Text.StringBuilder sb = new System.Text.StringBuilder();

sb.Append("");

return sb.ToString();

}

}

}

二。前台拼字符串JS调用写法

FLV需要播放器，其它视频格式直接插入相应的代码即可。

-------------------------------------

/**

*参数说明

u - 媒体URL

w - 媒体宽度width

h - 媒体高度height

*/

//播放Mediaplayer格式的视频，包括.avi .mpg .mpeg .wmv .wma .asf .mid .mp3等

function pv_m(u, w, h){

var pv='';

pv += '';

document.write(pv);

}

//播放Realplay格式的视频，包括.rm .ram .rmvb等

function pv_r(u, w, h){

var pv='';

pv += '';

document.write(pv);

}

//播放Quicktime格式的视频，包括.mov .amr .3gp等

function pv_q(u, w, h){

var pv='';

pv += '';

document.write(pv);

}
