How to trim the video with start & end time in android programmatically?

Question

I want to trim the local video based on start and end time in android programmatically ,I tried below attached few links but haven't worked for me.Please let me know any working libraries or sample code to overcome this?

Refereed links:

1. Android sdk cut/trim video file
2. How to trim the video using FFMPEG library in android?
3. https://superuser.com/questions/377343/cut-part-from-video-file-from-start-position-to-end-position-with-ffmpeg

Thanks in advance!

Answer 1

Use FFMPEG library to solve your problem. Thanks for writingminds to make ffmpeg simple for android 1. implementation 'com.writingminds:FFmpegAndroid:0.3.2'

2. initialize ffmpeg

   private void setUpFFmpeg() {
   ffmpeg = FFmpeg.getInstance(context);
   
   
   try {
       ffmpeg.loadBinary(new LoadBinaryResponseHandler() {
   
           @Override
           public void onStart() {
               Log.d("Event ", "onStart");
           }
   
           @Override
           public void onFailure() {
               Log.d("Event ", "onFailure");
           }
   
           @Override
           public void onSuccess() {
               Log.d("Event ", "onSuccess");
           }
   
           @Override
           public void onFinish() {
               Log.d("Event ", "onFinish");
   
           }
       });
   } catch (FFmpegNotSupportedException e) {
       // Handle if FFmpeg is not supported by device
   }
   }
   

3. use FFMPEG command like @Mahesh Keshvala posted above. Good work @Mahesh

4. then execFFmpegBinary(complexCommand); will be like this

   private void execFFmpegBinary(String[] command){
         try {
   
       ffmpeg.execute(commands, new ExecuteBinaryResponseHandler() {
   
           @Override
           public void onStart() {
               Log.d("Event ", "onStart");
           }
   
           @Override
           public void onProgress(String message) {
               Log.e("Event ", "onProgress - " + message);
   
           }
   
           @Override
           public void onFailure(String message) {
               Log.e("Event ", "onFailure - " + message);
   
           }
   
           @Override
           public void onSuccess(String message) {
               Log.e("Event ", "onSuccess - " + message);
   
           }
   
           @Override
           public void onFinish() {
               Log.e("Event ", "onFinish");
   
           }
       });
   } catch (FFmpegCommandAlreadyRunningException e) {
       // Handle if FFmpeg is already running
    }
   }
   

try command for cut video

String[] complexCommand = {"-ss", "" + startMs / 1000, "-y", "-i", inputFileAbsolutePath, "-t", "" + (endMs - startMs) / 1000, "-s", "320x240", "-r", "15", "-vcodec", "mpeg4", "-b:v", "2097152", "-b:a", "48000", "-ac", "2", "-ar", "22050", outputFileAbsolutePath};

Answer 2

Here is the solution using FFMPEG library use below function to trim or cut the video, may this will work for you:

private void executeCutVideoCommand(int startMs, int endMs) {
    File moviesDir = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_MOVIES
    );

    String filePrefix = "cut_video";
    String fileExtn = ".mp4";
    String yourRealPath = getPath(VideoEffectActivity.this, selectedVideoUri);
    File dest = new File(moviesDir, filePrefix + fileExtn);
    int fileNo = 0;
    while (dest.exists()) {
        fileNo++;
        dest = new File(moviesDir, filePrefix + fileNo + fileExtn);
    }

    Log.d(TAG, "startTrim: src: " + yourRealPath);
    Log.d(TAG, "startTrim: dest: " + dest.getAbsolutePath());
    Log.d(TAG, "startTrim: startMs: " + startMs);
    Log.d(TAG, "startTrim: endMs: " + endMs);
    filePath = dest.getAbsolutePath();
    //String[] complexCommand = {"-i", yourRealPath, "-ss", "" + startMs / 1000, "-t", "" + endMs / 1000, dest.getAbsolutePath()};
    String[] complexCommand = {"-ss", "" + startMs / 1000, "-y", "-i", yourRealPath, "-t", "" + (endMs - startMs) / 1000, "-vcodec", "mpeg4", "-b:v", "2097152", "-b:a", "48000", "-ac", "2", "-ar", "22050", filePath};

    execFFmpegBinary(complexCommand);

}


 private void execFFmpegBinary(final String[] command) {
    try {
        ffmpeg.execute(command, new ExecuteBinaryResponseHandler() {
            @Override
            public void onFailure(String s) {
                Log.d(TAG, "FAILED with output : " + s);
            }

            @Override
            public void onSuccess(String s) {
                Log.d(TAG, "SUCCESS with output : " + s);
               //You have to create a class of Preview Activity
               //If you don't have please remove below Intent code
                    Intent intent = new Intent(VideoEffectActivity.this, PreviewActivity.class);
                    intent.putExtra(FILEPATH, filePath);
                    startActivity(intent);
            }

            @Override
            public void onProgress(String s) {
                    progressDialog.setMessage("progress : " + s);
                Log.d(TAG, "progress : " + s);
            }

            @Override
            public void onStart() {
                Log.d(TAG, "Started command : ffmpeg " + command);
                progressDialog.setMessage("Processing...");
                progressDialog.show();
            }

            @Override
            public void onFinish() {
                Log.d(TAG, "Finished command : ffmpeg " + command);
               progressDialog.dismiss();
            }
        });
    } catch (FFmpegCommandAlreadyRunningException e) {
        // do nothing for now
    }
}
