    I have the developers version of ffmpeg lib and include files in with my shared ffmpeg file. How do I get it to work ?

    I have included -lmingw32-libarchive and -lsdlmain to avoid winmain16 error, should I do something else ? How to avoid deprecated error ?

  • Concatenating video using FFMPEG wrapper class [duplicate]

    21 décembre 2017, par alan samuel

    This question already has an answer here :

    I am trying to concatenate video using NReco.VideoConverter wrapper class made for FFMPEG.

    I have three video files with the same frame rate and same frame size.

    Here is what I have done.

            string toconcatfile = @"C:\Users\Alan\Desktop\Black.mp4";
    
        string output1 = @"C:\Users\Alan\Desktop\output1.mp4";
    
        string output2 = @"C:\Users\Alan\Desktop\output2.mp4";
    
        string finaloutput = @"C:\Users\Alan\Desktop\finaloutput.mp4";

    All the three videos have a frame rate of 25 and Video frame size yet it fails when I add in toconcatfile to the final conversion method.

    It works when its just output1 and output2 meaning there must be a different setting in toconcatfile.

    Here is what I have tried.

            FFMpegConverter fFMpeg = new FFMpegConverter();
    

    

    
        //Slices first video
    
        ConvertSettings settings = new ConvertSettings
    
        {
    
            VideoFrameRate = 25,
    
            VideoFrameSize = FrameSize.hd480,
    
            MaxDuration = startcut,
    
            AudioSampleRate = 44100
    

    
        };
    

    
        //Slices second video
    
        ConvertSettings settings2 = new ConvertSettings
    
        {
    
            VideoFrameRate = 25,
    
            VideoFrameSize = FrameSize.hd480,
    
            Seek = endcut,
    
            AudioSampleRate = 44100
    

    
        };
    
        //Copies framerate and size from the previous video to the concatenation video
    
        ConvertSettings settings3 = new ConvertSettings
    
        {
    
            VideoFrameRate = 25,
    
            VideoFrameSize = FrameSize.hd480,
    
            MaxDuration = 4,
    
            AppendSilentAudioStream = true,
    
            AudioSampleRate = 44100
    

    
        };
    

    

    
  string newblack = @"C:\Users\Alan\Desktop\newblack.mp4";
    

    
        //Slice method called
    
        fFMpeg.ConvertMedia(pathtofile, Format.mp4, output1, Format.mp4, settings);
    
        fFMpeg.ConvertMedia(pathtofile, Format.mp4, output2, Format.mp4, settings2);
    
        fFMpeg.ConvertMedia(toconcatfile, Format.mp4, newblack, Format.mp4, settings3);
    

    
        String[] inputfiles = new String[2];
    
        inputfiles[0] = output1;
    
        inputfiles[1] = newblack;
    
        //inputfiles[1] = output2;
    

    

    
        ConcatSettings concatSettings = new ConcatSettings
    
        {
    
            //CustomOutputArgs = output1+" "+ toconcatfile+ " "+output2+ " -filter_complex \"[0:v:0][0:a:0][1:v:0][1:a:0][2:v:0][2:a:0]concat=n=3:v=1:a=1[outv][outa]\" -map \"[outv]\" - map \"[outa]\""
    
        };
    

    
        fFMpeg.ConcatMedia(inputfiles, finaloutput, Format.mp4, concatSettings);

    Can anyone help ?

    Edit : I get the exception message - "Invalid argument (exit code : 1)",
