在线转化视频问题 请大家帮忙看下错在什么地方,好象ffmpeg.exe 就没起作用.

public void ConvertVideo(string str)
{
Process p = new Process();//建立外部调用线程
p.StartInfo.FileName = @"E:\2008Erp\BBS\FLV\ffmpeg.exe";//要调用外部程序的绝对路径
p.StartInfo.Arguments = str;//参数(这里就是FFMPEG的参数了)
p.StartInfo.UseShellExecute = false;//不使用操作系统外壳程序启动线程(一定为FALSE,详细的请看MSDN)
p.StartInfo.RedirectStandardError = true;//把外部程序错误输出写到StandardError流中(这个一定要注意,FFMPEG的所有输出信息,都为错误输出流,用StandardOutput是捕获不到任何消息的...
p.StartInfo.CreateNoWindow = false;//不创建进程窗口
p.Start();//启动线程
p.WaitForExit();//等待完成
p.StandardError.ReadToEnd();//开始同步读取
p.Close();//关闭进程
p.Dispose();//释放资源
}
protected void Button1_Click(object sender, EventArgs e)
{
string Mapname = DateTime.Now.ToString().Replace(" ", "").Replace("-", "").Replace(":", "");
string str1 = FileUpload1.PostedFile.FileName.ToString();
string name = System.IO.Path.GetExtension(str1);
FileUpload1.PostedFile.SaveAs(Server.MapPath("FLV/vidio/" + Mapname + "" + name + ""));
string str2 = System.Web.HttpContext.Current.Server.MapPath("Flv/vidio/");
ConvertVideo("-i " + str1 + " -ab 56 -ar 22050 -b 500 -r 15 -s 320x240 " + str2 + "\\" + Mapname + ".flv");
Response.Write(" <script>alert('转换成功!'); </script>");
}


E:\2008Erp 这是我项目的存放地方

来几个行家啊...

[fox1025701]

自己顶一下..

[fox1025701]

自己给自己定起来,怎么就没人来呢

创建进程窗口看是否启用

Server.MapPath获取ffmpeg.exe地址

[fox1025701]

高手都被这么低碉啊...会被埋没的
