  • How to import and use FFmpegInteropX.FFmpegUWP ?

    14 janvier, par Boris

    I am writing a WinUI3 app. I need it to play a .mkv video file using MediaPlayerElement control. Out of box, .mkv file types are not supported. So I came upon a package FFmpegInteropX.FFmpegUWP (current v5.1.100) and installed it to the solution via Visual Studio NuGet Package Manager. The installation went fine and the package is definitely part of the project :

    


    <packagereference include="FFmpegInteropX.FFmpegUWP" version="5.1.100"></packagereference>

    &#xA;

    The problem I have is that when I type using FFmpegInteropX; it is not recognized and I cannot use it. I've noticed there is also a FFmpegInteropX package (so without the ".FFmpegUWP" part) and I tried installing that one too, as I was trying to make the using statement work. However, it appears that that package is not intended for WinUI3 projects and NuGet removed it.

    &#xA;

    Now, I am clueless on how to use the FFmpegInteropX.FFmpegUWP in the project. Could anyone please explain why I might be experiencing this problem ?

  • ffmpeg.exe freezes

    17 mars 2015, par Ayhan Dorman

    I’m using Asp.Net C# Framework 4 and currently developing a video conversion application. I’m also using ffmpeg to convert from all uploaded formats to flv. I’m first converting uploaded file to mpg and after to flv due to problems I encountered while trying conversion directly to flv from mp4 sometimes. But ffmpeg freezes as soon as it’s done with conversion process to mpg file. When I run task manager and check the processes list, it just stands there using no CPU resource. When I end the ffmpeg process directly from task manager, other process take place which converts from mpg to flv and preview file (jpg) and works smoothly. Due to freezing of first process, the second process cannot start when I try to upload from my web page’s file upload form. I appreciate any response from now. Here is my code :

            string duration = "00:00:00";
    

    
        //converting video
    
        Process ffmpeg;
    
        ffmpeg = new Process();
    

    
        // convert to mpg 1st
    
        ffmpeg.StartInfo.Arguments = " -i \"" + Server.MapPath("static/user/vid/") + videolink + "\" -f mpeg -b 300k -ac 2 -ab 128k -ar 44K \"" + Server.MapPath("static/user/vid/") + mpglink + "\"";
    
        ffmpeg.StartInfo.FileName = Page.MapPath("bin/ffmpeg.exe");

        ffmpeg.BeginOutputReadLine();
    
        string error = ffmpeg.StandardError.ReadToEnd();
    
        ffmpeg.WaitForExit();
    

    
        try
    
        {
    
            duration = error.Substring(error.IndexOf("Duration: ") + 10, 8);
    
        }

        {
    
        }

        {
    
            ltrUpload.Text = "<div class="\&quot;resultbox-negative\&quot;">Problem occured during upload process. Error code: " + error + "<br />" + "</div>";
    
            return;
    
        }
    
        ffmpeg.Close();
    

    

    
        // generate preview image
