上的ProcessStartInfo ffmpeg的C＃asp.net帮助(ffmpeg c# as

我写的代码使用的ffmpeg转换的文件在C＃asp.net。 当执行它显示的错误为“文件名，目录名或卷标语法不正确”，但我的路径是正确的。 那么究竟是什么解决办法吗？

ProcessStartInfo info = new ProcessStartInfo("e:\ffmpeg\bin\ffmpeg.exe", "-i cars1.flv -same_quant intermediate1.mpg");

process.Start();

我尝试另一种方式，如下图所示。 但是，这也不会工作。

ProcessStartInfo info = new ProcessStartInfo("ffmpeg.exe", "-i cars1.flv -same_quant intermediate1.mpg");

请帮我与示例代码在C＃中asp.net一个视频文件格式转换为另一种使用的ffmpeg。 提前致谢。

Answer 1:

The backslashes (\) in your path are considered to start escape sequences. To prevent this, either use double backslashes (\\), or prefix the string with @.

ProcessStartInfo info = new ProcessStartInfo("e:\\ffmpeg\\bin\\ffmpeg.exe", 
                         "-i cars1.flv -same_quant intermediate1.mpg");

Or:

ProcessStartInfo info = new ProcessStartInfo(@"e:\ffmpeg\bin\ffmpeg.exe", 
                         "-i cars1.flv -same_quant intermediate1.mpg");

    string apppath = Request.PhysicalApplicationPath; 

    string outf = Server.MapPath(".");

    string fileargs = "-i" + " " + "\"C:/file.mp4 \"" + " " + "\"C:/files/test.flv \"";

    Process myProcess = new Process();

    myProcess.StartInfo.FileName = Server.MapPath(".")+"//ffmpeg.exe";

    myProcess.StartInfo.Arguments = fileargs;

    myProcess.StartInfo.UseShellExecute = false;

    myProcess.StartInfo.CreateNoWindow = false;

    myProcess.StartInfo.RedirectStandardOutput = false;

    myProcess.Start();

    myProcess.WaitForExit(50 * 1000);

你需要在你的路径反斜杠见下文我这是怎么创建使用ffmpeg.exe视频

        string sConverterPath = @"C:\ffmpeg.exe";
        string sConverterArguments = @" -i ";
        sConverterArguments += "\"" + sAVIFile + "\"";
        sConverterArguments += " -s " + iVideoWidth.ToString() + "x" + iVideoHeight.ToString() + " ";
        sConverterArguments += " -b " + iVideoBitRate.ToString() + "k -ab " + iAudioBitRate.ToString() + "k -ac 1 -ar 44100 -r 24 -absf remove_extra ";
        sConverterArguments += "\"" + sOutputFile + "\"";


        Process oProcess = new Process();
        oProcess.StartInfo.UseShellExecute = true;
        oProcess.StartInfo.Arguments = sConverterArguments;
        oProcess.StartInfo.FileName = sConverterPath;
