• FFMPEG "Could find no file with path" and "No such file or directory"

  4 mai 2020, par bmw_58

  I try to convert a sequence of pictures to video file. 
But I get from ffmpeg the response, that no such file or directory

  



  Does someone have a solution for it ?

  



  My command line :

  



  ffmpeg -r 1/5 -start_number 0 -i "C:\Users\USER\Desktop\Pictures\%3d.png" -c:v libx264 -r 30 -pix_fmt yuv420p C:\Users\USER\Desktop\Pictures\out.mp4


  



  The error :

  



          C:\Users\USER>ffmpeg -r 1/5 -start_number 0 -i "C:\Users\USER\Desktop\Pictures\%3d.png" -c:v libx264 -r 30 -pix_fmt yuv420p C:\Users\USER\Desktop\Pictures\out.mp4

            // Generate a unique file name based on the current date and time
            string fileName = DateTime.Now.ToString("Screen_yyyyMMdd_HHmmss") + ".mp4";

            // Set the output file path
            string outputFile = Path.Combine(outputFolder, fileName);

            // FFmpeg command to record the whole screen
            string ffmpegCommand = $"-f gdigrab -framerate 24 -i desktop -preset ultrafast -pix_fmt yuv420p \"{outputFile}\"";

            StartFFmpeg(ffmpegCommand);
        }


  


  the method startffmpeg

  


  private void StartFFmpeg(string command)
        {
            // Send the FFmpeg command to the process for execution
            ffmpegProcess.StandardInput.WriteLine(command);
            ffmpegProcess.StandardInput.Flush();
        }


  


  but when running the application pressing the button to record after some seconds i click the form red X on the top right to close it but it's not saving the mp4 output file. not sure if it's even recording at all.

  


• shell scripting no such file or directory

  15 mars 2018, par Toto Tata

  I wrote a shell script that calls the ffmpeg tool but when I run it, it says No such file or directory yet it does !

  Here is my script :

  #!/bin/bash
  
  
  
  MAIN_DIR="/media/sf_data/pipeline"
  
  
  
  FFMPEG_DIR="/media/sf_data/livraison_transcripts/ffmpeg-git-20180208-64bit-static"
  
  
  
  for file in MAIN_DIR/audio_mp3/*.mp3;
  
  do
  
      cp -p file FFMPEG_DIR;
  
  done
  
  
  
  for file in FFMPEG_DIR/*.mp3;
  
  do
  
      ./ffmpeg -i ${file%.mp3}.ogg
  
      sox $file -t raw --channels=1 --bits=16 --rate=16000 --encoding=signed-
  
  integer --endian=little ${file%.ogg}.raw;
  
  done
  
  
  
  for file in FFMPEG_DIR/*.raw;
  
  do
  
      cp -p file MAIN_DIR/pipeline/audio_raw/;
  
  done

  and here is the debug response :

  cp: cannot stat ‘file’: No such file or directory
  
  ./essai.sh: line 14: ./ffmpeg: No such file or directory
  
  sox FAIL formats: can't open input file `FFMPEG_DIR/*.mp3': No such file or 
  
  directory
  
  cp: cannot stat ‘file’: No such file or directory

  FYI I’m running CentOS7 on VirtualBox

  Thank you
