篇首语：读过一本好书，像交了一个益友。本文由小常识网(cha138.com)小编为大家整理，主要介绍了知识大全上传视频并将各种视频文件转换成.flv格式相关的知识，希望对你有一定的参考价值。

　　首先我们部署一下文件夹在工程的目录下新建几个文件夹如下图

　　UpFiles文件夹是要保存你上传的文件 PlayFiles文件夹是用于你转换后保存的文件（用于网上播放）ImgFile文件夹是保存截取视频文件的图片然后那两个mencoder和ffmpeg文件夹是视频转换工具此视频转换也可叫做mencoder+ffmpeg视频转换首先在配置文件中给这些文件夹进行路径的配置如下 CODE:<appSettings><! 工具文件夹 ><add key= ffmpeg value= ffmpeg/ffmpeg exe /><add key= mencoder value= mencoder/mencoder exe /><add key= mplayer value= mencoder/mplayer exe /><! 上传文件的路径 ><add key= upfile value= UpFiles /><! 上专文件图片路径 ><add key= imgfile value= ImgFile /><! 上传文件图片大小 ><add key= CatchFlvImgSize value= x /><add key= widthSize value= /><add key= heightSize value= /><! 转换后文件路径 ><add key= playfile value= PlayFiles /></appSettings>

　　在上传 ASPX页面中

　　CODE:标题 <asp:TextBox ID= txtTitle runat= server Width= px ></asp:TextBox><asp:RequiredFieldValidator ID= RequiredFieldValidator runat= server ControlToValidate= txtTitle ErrorMessage= 标题不为空 ></asp:RequiredFieldValidator><br /><asp:FileUpload ID= FileUpload runat= server Width= px /><asp:Button ID= btnUpload runat= server OnClick= btnUpload_Click Text= 上传视频 Width= px />文件类型<span >( asf| flv| avi| mpg| gp| mov| wmv| rm| rmvb)</span><asp:RegularExpressionValidator ID= imagePathValidator runat= server ErrorMessage= 文件类型不正确 ValidationGroup= vgValidation Display= Dynamic ValidationExpression= ^[a zA Z]:(\\\\ +)( asf| flv| avi| mpg| gp| mov| wmv| rm| rmvb)$ ControlToValidate= FileUpload ></asp:RegularExpressionValidator><asp:RequiredFieldValidator ID= RequiredFieldValidator runat= server ControlToValidate= FileUpload ErrorMessage= 文件不为空 ></asp:RequiredFieldValidator></div><div ></div><div>上传列表 </div>

　　程序工作的原理是视频先上传上去然后跟着就是开始转换所以在CS 文件中有这里为了方便我是用sqlDatasource数据控件做数据的操作

　　CODE:using System;using System Data;using System Configuration;using System Web;using System Web Security;using System Web UI;using System Web UI WebControls;using System Web UI WebControls WebParts;using System Web UI HtmlControls;public partial class _Default : System Web UI Page // 扩展名定义string[] strArrFfmpeg = new string[] asf avi mpg gp mov ;string[] strArrMencoder = new string[] wmv rm rmvb ;protected void Page_Load(object sender EventArgs e)//protected void btnUpload_Click(object sender EventArgs e)string upFileName = ;if (this FileUpload HasFile)string fileName = PublicMethod GetFileName(this FileUpload FileName);// GetFileName();if ((string)Session[ file ] == fileName)return;upFileName = Server MapPath(PublicMethod upFile + fileName);this FileUpload SaveAs(upFileName);string saveName = DateTime Now ToString( yyyyMMddHHmmssffff ) ;string playFile = Server MapPath(PublicMethod playFile + saveName);string imgFile = Server MapPath(PublicMethod imgFile + saveName);//System IO File Copy(Server MapPath(PublicMethod playFile + jpg ) Server MapPath(PublicMethod imgFile+ aa jpg ));PublicMethod pm = new PublicMethod();string m_strExtension = PublicMethod GetExtension(this FileUpload PostedFile FileName) ToLower();if (m_strExtension == flv )//直接拷贝到播放文件夹下System IO File Copy(upFileName playFile+ flv );pm CatchImg(upFileName imgFile);string Extension = CheckExtension(m_strExtension);if (Extension == ffmpeg )　　pm ChangeFilePhy(upFileName playFile imgFile);else if (Extension == mencoder )pm MChangeFilePhy(upFileName playFile imgFile);InsertData(this txtTitle Text fileName saveName);Session[ file ] = fileName;//private string CheckExtension(string extension)string m_strReturn = ;foreach (string var in this strArrFfmpeg)if (var == extension)m_strReturn = ffmpeg ; break;if (m_strReturn == )foreach (string var in strArrMencoder)if (var == extension)m_strReturn = mencoder ; break;return m_strReturn;

　　#region 插入数

　　据到数据库中
