• Quickly check the integrity of video files inside a directory with ffmpeg with windows

  20 avril 2017, par Mathias Nervik

  I am checking the integrity of a lot of video files from a directory. I found this question (for Ubuntu). My question is what the code would be if I wanted to do the same on my Windows machine.

  ffmpegBin-folder: /downloads/ffmpeg/bin
  
  <br />
  
  videoSource-folder: /downloads/ffmpeg/videos
  
  <br />
  
  error-Folder: /downloads/ffmpeg/error

  When I do it with every single file instead of for the whole directory, I use the folowing code :

  bin\ffmpeg.exe -v error -i videos\fileName.mp4 -f null - >error\fileName.log 2>&1

  PS. All the videos have the ".mp4" extension, but preferably I would like to fetch all the files despite them having different extension.

• Automating Basic Video Editing [closed]

  2 février, par user29470652

  What's guys ! I am a beginner in programming.

  


  As of now, I have created a basic YouTube downloader with the help of Python, FFmpeg, yt dlp, and Flaskapp.

  


  Now, I am automating the basic video editing part ( Turn bulk video files into a basic similar edit like we have one template then we add a caption from the title of the video, then place the video in the center of the template trim out to meet the video length of the given video then saving it) with the help of FFmpeg.

  


  Has anyone already tried or built it ?? Any marketer or video editor ??

  


  I am halfway to the project

  


  Here is theenter image description here

  


  I am halfway through the project and wonder if anyone has ever done it before like any video editor or marketer ??

  


• How to change or modify pitch of audio file (music etc like .mp3 file)using FFMPEG ?

  18 octobre 2022, par syed kashifullah

  I want to change and modify pitch an .mp3 audio file using FFMPEG.
But I am unable to use FFMPEG to change or modify pitch of that sound.
what command (exact command) should be exactly use for changing pitch of an audio file ?

  


   String outPutPath = new File("/storage/emulated/0/Share it Application/Over_the_HorizonTemp.wav").getPath();
                 
                String[] strFfmpeg  = {"ffmpeg","-i" ,strInputPath,"-af", "rubberband=tempo=1.0:pitch=1.5:pitchq=quality" ,outPutPath};
                execffmpegBinary(strFfmpeg);


  


  execffmpegBinary Function :

  


  public void execffmpegBinary(String[] command) {
    Config.enableLogCallback(new LogCallback() {
        @Override
        public void apply(LogMessage message) {
            Log.e(Config.TAG, message.getText());
            Log.e("TAG", "apply: " +message.getText());
        }
    });
    Config.enableStatisticsCallback(new StatisticsCallback() {
        @Override
        public void apply(Statistics statistics) {

        }
    });

    long executionId = FFmpeg.executeAsync(command, new ExecuteCallback() {
        @Override
        public void apply(long executionId, int returnCode) {
            if (returnCode == RETURN_CODE_SUCCESS) {
                
                Log.e("1TAG", "apply:return code "+returnCode );
                Log.e("1TAG", "apply:execution Id "+executionId );
                Log.e("1TAG", "apply:execution Id "+ new FFmpegExecution(executionId,command));


            } else if (returnCode == RETURN_CODE_CANCEL) {
                Log.e("2TAG", "apply:return code "+returnCode );
                Log.e("2TAG", "apply:execution Id "+executionId );
                Log.e("2TAG", "apply:execution Id "+ new FFmpegExecution(executionId,command));

            } else {
                Log.e("3TAG", "apply: returnCode"+ returnCode);
                Log.e("3TAG", "apply:return code "+returnCode );
                Log.e("3TAG", "apply:execution Id "+executionId );
                Log.e("3TAG", "apply:execution Id "+ new FFmpegExecution(executionId,command));

            }
        }
    });
