• Is there any way to edit just the track data of an AVI file, like mkvpropedit does with MKV files ?

  20 juillet 2016, par hmj6jmh

  I am trying to swap the order of 2 audio tracks of an AVI file using ffmpeg.

  ffmpeg -i "infile.avi" -map 0:0 -map 0:2 -map 0:1 -c copy "outfile.avi"

  This works but the file is being re-encoded, not copied. It takes much longer than a straight copy to finish and the resulting file is larger than the original.

  Is there any way to edit just the track data of an AVI file, like mkvpropedit does with MKV files ? Command line tool preferred.

• ffmpeg extracting frames from video

  22 novembre 2017, par TheOtherguyz4kj

  I am using Writingminds FFmpeg to use FFmpeg with Android. I am currently trying to extract frames from a video.

  I would like to extract 8 frames from the video evenly distributed throughout the video. I found this tutorial here is my implementation of it.

  MediaMetadataRetriever retriever = new MediaMetadataRetriever();
  
      retriever.setDataSource(videoCroppedFile.getAbsolutePath());
  
      String time = retriever.extractMetadata(MediaMetadataRetriever.METADATA_KEY_DURATION);
  
      Long videoLength = Long.parseLong(time);
  
  
  
  
  
  final String cmd[] = {
  
  
  
              "-i",
  
              videoCroppedFile.getAbsolutePath(),
  
              "-f",
  
              "image2",
  
              "-ss",
  
              String.valueOf(videoLength.intValue() / ((8 + 1) * 10)),
  
              "-r",
  
              String.valueOf((8 + 1) / videoLength.intValue()),
  
              mediaStorageDir.getAbsolutePath() + "/%d.jpg"
  
      };

  However, when i go to the folder where the frames should be saved there isn’t anything there. Also there are no error messages.

  I feel like its a way this library takes the String parameters. I’ve been stuck on this for sometime I have tried lots of different versions of the cmd. I was hoping someone could help.

  Here is my output from ffmpeg :

  Update 2

  Here is my Android code :

        try {
  
          ffmpeg.loadBinary(new LoadBinaryResponseHandler() {
  
  
  
              @Override
  
              public void onStart() {
  
                  Log.d("videoFrames", "starting to load binary");
  
              }
  
  
  
              @Override
  
              public void onFailure() {
  
                  Log.d("videoFrames", "failed to load binary");
  
              }
  
  
  
              @Override
  
              public void onSuccess() {
  
                  Log.d("videoFrames", "loaded binary");
  
                  try {
  
                      ffmpeg.execute(cmd, new ExecuteBinaryResponseHandler() {
  
  
  
                          @Override
  
                          public void onStart() {
  
                              Log.d("videoFrames", " starting to get frames from video");
  
                              if (mediaStorageDir.isDirectory() && mediaStorageDir.list().length > 0) {
  
                                  String[] children = mediaStorageDir.list();
  
                                  for (int i = 0; i < children.length; i++) {
  
                                      new File(mediaStorageDir, children[i]).delete();
  
                                  }
  
                              }
  
                          }
  
  
  
                          @Override
  
                          public void onProgress(String message) {
  
                              Log.d("videoFrames", " progress getting frames from video");
  
                          }
  
  
  
                          @Override
  
                          public void onFailure(String message) {
  
                              Log.d("videoFrames", " failed to get frames from video");
  
                              Log.d("videoFrames", " failure reason " + message);
  
                              Log.d("videoFrames", " ----------------------------------------------- ");
  
                          }
  
  
  
                          @Override
  
                          public void onSuccess(String message) {
  
                              Log.d("videoFrames", " success getting frames from video");
  
                          }
  
  
  
                          @Override
  
                          public void onFinish() {
  
                              Log.d("videoFrames", " finished getting frames from video");
  
                          }
  
                      });
  
                  } catch (FFmpegCommandAlreadyRunningException e) {
  
                      Log.d("videoFrames", " command already running in fmpeg");
  
                      e.printStackTrace();
  
                  }
  
              }
  
  
  
              @Override
  
              public void onFinish() {}
  
          });
  
      } catch (FFmpegNotSupportedException e) {
  
          // Handle if FFmpeg is not supported by device
  
      }

  Update 3

  I fixed my code by doing :

   final String cmd[] = {
  
  
  
              "-i",
  
              videoCroppedFile.getAbsolutePath(),
  
              "-f",
  
              "image2",
  
              "-ss",
  
              String.valueOf(videoLength.floatValue() / (8.0  * 10.0)),
  
              "-r",
  
              String.valueOf(8.0 / videoLength.floatValue()),
  
              mediaStorageDir.getAbsolutePath() + "/%d.jpg"
  
      };
