  Error : unable to open display

  


  


  I tried running the code from a line, and from a file. but it always gives my the same error. I don't know what is causing it but I hope someone can help.

  


• how to send the input data to FFMPEG from a C# program

  18 octobre 2020, par jstuardo

  I need to send a binary stream to FFMPEG so that it sends to an RTMP server.

  


  I did it in a nodejs script using socket.io library and in Linux. It works perfectly.

  


  I need to do the same, but in a Windows Forms application using C#.

  


  This is how I run the ffmpeg.exe application :

  


          _currentProcess = new Process();
        _currentProcess.StartInfo.FileName = _ffmpegExe;
        _currentProcess.StartInfo.Arguments = BuildOptions(framesPerSecond, audioBitRate, audioEncoding, rtmpServer);
        _currentProcess.StartInfo.UseShellExecute = false;
        _currentProcess.StartInfo.CreateNoWindow = true;
        _currentProcess.StartInfo.RedirectStandardInput = true;
        _currentProcess.StartInfo.RedirectStandardError = true;
        _currentProcess.ErrorDataReceived += CurrentProcess_ErrorDataReceived;
        _currentProcess.Start();
        _currentProcess.BeginErrorReadLine();


  


  BuildOptions method is defined this way :

  


      private string BuildOptions(int framesPerSecond, int audioBitRate, string audioEncoding, string rtmpServer)
    {
        string options;
        if (framesPerSecond == 1)
        {
            options = $"-i - -c:v libx264 -preset ultrafast -tune zerolatency -r 1 -g 2 -keyint_min 2 -x264opts keyint=2 -crf 25 -pix_fmt yuv420p -profile:v baseline -level 3 -c:a aac -b:a {audioEncoding} -ar {audioBitRate}-f flv {rtmpServer}";
        }
        else if (framesPerSecond == 15)
        {
            options = $"-i - -c:v libx264 -preset ultrafast -tune zerolatency max_muxing_queue_size 1000 -bufsize 5000 -r 15 -g 30 -keyint_min 30 -x264opts keyint=30 -crf 25 -pix_fmt yuv420p -profile:v baseline -level 3 -c:a aac -b:a {audioEncoding} -ar {audioBitRate} -f flv {rtmpServer}";
        }
        else
        {
            options = $"-i - -c:v libx264 -preset ultrafast -tune zerolatency -c:a aac -ar {audioBitRate} -b:a {audioEncoding} -bufsize 5000 -f flv {rtmpServer}";
        }

        return options;
    }


  


  I am sending the data to the standard input this way :

  


      public void EncodeAndSend(byte[] data)
    {
        if (_currentProcess != null)
        {
            var streamWriter = _currentProcess.StandardInput;
            streamWriter.Write(Encoding.GetEncoding("ISO-8859-1").GetChars(data));
        }
    }


  


  And finally, this method is for receiving the standard error which receives the result from ffmpeg.exe :

  


      private void CurrentProcess_ErrorDataReceived(object sender, DataReceivedEventArgs e)
    {
        Console.WriteLine(e.Data);
    }


  


  When I run the application, this is shown in the console :

pipe:: Invalid data found when processing input


  


  If I change the EncodeAndSend method to be :

  


      public void EncodeAndSend(byte[] data)
    {
        if (_currentProcess != null)
        {
            var streamWriter = _currentProcess.StandardInput;
            streamWriter.Write(data);
        }
    }


  


  pipe:: Invalid data found when processing input error is not produced, but no more outputs are shown so it seems it is not working.

  


  What is wrong with this ? how can I send the data to the FFMPEG process ?

  


  Finally, I tell you that the binary stream comes from the camera by mean of MediaRecorder in a web page (the same used for my program in nodejs server, so that it is not the issue here)

  


• Attempting to compile FFmpeg 4.2.3 statically for Windows 10 (x86_64), but binaries asks for missing DLLs

  29 mai 2020, par Expectator

  I am using Msys MinGW (x86_64) and pulled a snapshot of the latest major release of FFmpeg off of their website. Here is my ./configure options. I plan to use the binaries on both the computer that I compiled it on, and other Windows computers that I own.

  



  ./configure --enable-libaom --enable-avisynth --enable-chromaprint --enable-libdav1d --enable-libdavs2 --enable-libgme --enable-libmfx --enable-libkvazaar --enable-libmp3lame --enable-libilbc --enable-libvpx --enable-libmodplug --enable-version3 --enable-nonfree --enable-libopencore-amrnb --enable-libopencore-amrwb --enable-libvo-amrwbenc --enable-libfdk-aac --enable-libopenh264 --enable-libopenjpeg --enable-nvenc --enable-nvdec --enable-cuda --enable-cuvid --enable-libtwolame --enable-vapoursynth --enable-libwavpack --enable-libx264 --enable-libx265 --enable-libxavs --enable-libxavs2 --enable-gpl --enable-static --disable-shared


  



  Output of configure script (pastebin)

  



  Output of uname -a (in Msys)

  



  MINGW64_NT-10.0-18362 <scrubbed> 3.1.4-340.x86_64 2020-05-22 08:28 UTC x86_64 Msys&#xA;</scrubbed>

  



  The issue that I'm facing is that despite passing the options --enable-static and --disable-shared, the executables generated still require libchromaprint.dll, libfdk-aac-2.dll, and libgme.dll to run. What I expected was that FFmpeg would execute independently of any DLL files since I passed those options to ./configure.
