• Package is installed inside docker but actual command provide exception

  1er juin 2022, par user1765862

  I'm trying to use ffmpeg core package inside .net 6 dockerized project. I install ffmpeg core inside Dockerfile, reference actual package FFMpegCore inside solution but when I try to apply any of the commands from the ffmpeg core lib I'm getting error

  


  


  An error occurred trying to start process './ffmpeg' with working
directory '/var/task'. No such file or directory

  


  


  Docker build is done with no error.

  


  Dockerfile

  


  FROM public.ecr.aws/lambda/dotnet:6 AS base
....
RUN apt-get install -y ffmpeg
....
FROM base AS final
WORKDIR /var/task
COPY --from=publish /app/publish .


  


  As per ffmpeg core docs in order to use ffmpeg I need to set its binary folder, so I add ffmpeg.config.json

  


  {
  "BinaryFolder": "/var/task",
  "TemporaryFilesFolder": "/tmp"
}


  


  Actual error is being thrown when I try to execute following command

  


  


  An error occurred trying to start process './ffmpeg' with working
directory '/var/task'. No such file or directory

  


  


  This is the place where error gets triggered

  


   using FFMpegCore;&#xA; ...&#xA; public class MyController : ControllerBase&#xA;    {&#xA;        public async Task<string> Get()&#xA;        {    &#xA;             await FFMpegArguments&#xA;                   .FromPipeInput(new StreamPipeSource(myfile))&#xA;                   .OutputToPipe(new StreamPipeSink(outputStream), options => options&#xA;                      .WithVideoCodec("vp9")&#xA;                      .ForceFormat("webm"))&#xA;                      .ProcessAsynchronously();&#xA;             ...&#xA;        }    &#xA;    }&#xA;</string>

  


  Update :
After changing BinaryFolder location to /usr/bin I'm getting following error

  


  An error occurred trying to start process '/usr/bin/ffmpeg' with working directory '/var/task'. No such file or directory


  


  Update #2
This is my complete Dockerfile

  


  FROM public.ecr.aws/lambda/dotnet:6 AS base

• Picturebox from AForge FFMPEG empty - C#/WinForms

  1er août 2017, par Jake Delson

  I’ve done a ton of research and looked at a lot of questions here but can’t seem to find anything to help me. I should preface I’m very new to C#, Windows Forms, and SO ! I’m a 1st year CompSci student coming from C++ experimenting with my own projects for the summer. I’m trying to display a series of bitmaps from a .avi using the AForge.Video.FFMPEG video file reader.

  It seems to be finding the file, getting its’ data (console prints dimensions, framerate, and codec) and creating the picturebox, but the picturebox comes up blank/empty. I get the bitmap from the frames of a .avi :

  From AForge example code here

  Then I’m trying to display it with a picture box :

  From MS example code here as well

  And here’s my code. Essentially a combination of the two :

      public class Simple : Form
  
  {
  
      Bitmap videoFrame;
  
  
  
      public Simple()
  
      {
  
          try
  
          {
  
              // create instance of video reader
  
              VideoFileReader reader = new VideoFileReader();
  
              // open video file
  
              reader.Open(@"C:\Users\User\Desktop\ScanTest3.AVI");
  
              // check some of its attributes
  
              Console.WriteLine("width:  " + reader.Width);
  
              Console.WriteLine("height: " + reader.Height);
  
              Console.WriteLine("fps:    " + reader.FrameRate);
  
              Console.WriteLine("codec:  " + reader.CodecName);
  
  
  
              PictureBox pictureBox1 = new PictureBox();
  
  
  
              // read 100 video frames out of it
  
              for (int i = 0; i < 100; i++)
  
              {
  
                  videoFrame = reader.ReadVideoFrame();
  
  
  
                  pictureBox1.SizeMode = PictureBoxSizeMode.StretchImage;
  
                  pictureBox1.ClientSize = new Size(videoFrame.Width, videoFrame.Height);
  
                  pictureBox1.Image = videoFrame;
  
  
  
                  // dispose the frame when it is no longer required
  
                  videoFrame.Dispose();
  
              }
  
  
  
              reader.Close();
  
          }
  
  
  
          catch
  
          {
  
              Console.WriteLine("Nope");
  
          }
  
  
  
      }
  
  }
  
  
  
  class MApplication
  
  {
  
      public static void Main()
  
      {
  
          Application.Run(new Simple());
  
      }
  
  }

  So that’s it pretty much. Just a blank picture box coming up, when it should have the first frame of the video, even though no exception caught (though I’m pretty confident I’m using the try/catch very poorly), and the console printing the correct data for the file :

  width:  720
  
  height: 480
  
  fps:    29
  
  codec:  dvvideo
  
  [swscaler @ 05E10060] Warning: data is not aligned! This can lead to a speedloss

  Though if anyone could tell me what that warning means, that would be great as well, but I’m mainly just lost as to why there’s no picture printing to the screen.

  Thanks !
