  • FFmpeg Android Video cropping speed and perfomance [duplicate]

    5 octobre 2016, par kishore jethava

    This question already has an answer here :

    FFmpeg 15 seconds video takes 15 seconds to crop.
    How can we reduce this cropping time with command or some other tricks ?

    I have refereed this question but didn’t helped.

    Here is code

    final FFmpeg ffmpeg = FFmpeg.getInstance(getActivity());
    
        try {
    
            ffmpeg.loadBinary(new LoadBinaryResponseHandler() {
    

    
                @Override
    
                public void onStart() {}
    
                @Override
    
                public void onFailure() {}
    
                @Override
    
                public void onSuccess() {
    
                    Log.i(TAG, "FFMPEG Success ");
    
                    try {
    

    
                        /*Logic for cropping the original video to a square video depending of the                                           orientation of the original video*/
    

    
                        //Command for cropping square video
    
                        String[] cmd = {"-i", "path/source.mp4", "-vf", "scale=720:ih*720/iw, crop="720:720:0:0, "-preset","ultrafast","-strict","experimental","-vcodec","libx264","-preset","ultrafast","path/destination.mp4"};
    
                        // Execute cropping of video
    
                        ffmpeg.execute(cmd, new ExecuteBinaryResponseHandler() {
    

    
                            @Override
    
                            public void onStart() {
    

    
                            }
    

    
                            @Override
    
                            public void onProgress(String message) {
    
                                Log.i("Square", "progress : " +message);
    
                            }
    

    
                            @Override
    
                            public void onFailure(String message) {
    
                                Log.i("Square", "total fail : " + message);
    
                            }
    
                            @Override
    
                            public void onSuccess(String message) {
    
                                Log.i("Square", "Cropped video created.");
    

    
                            }
    
                            @Override
    
                            public void onFinish() {
    
                            }
    
                        });
    
                    } catch (FFmpegCommandAlreadyRunningException e) {
    
                        // Handle if FFmpeg is already running
    
                    }

    wtv : Speed up wtv index creation

    The index creation is O(N^2) with number of entries (typically thousands).
    
On a Pi this can take more than 60 seconds to execute for a recording of a few hours.
    

    By replacing with an O(N) loop, this takes virtually zero time

    16 septembre 2016, par user2455079

    Need to speed up video with MLT.
    I can do it with ffmpeg :

    -filter:v "setpts=0.5*PTS"

    But what about MLT ?
