  • Les vidéos

    21 avril 2011, par

    Comme les documents de type "audio", Mediaspip affiche dans la mesure du possible les vidéos grâce à la balise html5 .
    Un des inconvénients de cette balise est qu’elle n’est pas reconnue correctement par certains navigateurs (Internet Explorer pour ne pas le nommer) et que chaque navigateur ne gère en natif que certains formats de vidéos.
    Son avantage principal quant à lui est de bénéficier de la prise en charge native de vidéos dans les navigateur et donc de se passer de l’utilisation de Flash et (...)

  • 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
    
                    }
    
                }
    
            });

    The final video is available here, i’m able to read it from Safari on Mac OS, but it doesn’t work on iOS using AVPlayer or Safari.

    I also tried to play it using this sample code provided by Apple, however i get the following error :
    "The decoder required for this media cannot be found"

    Any help is appreciated

    edit 1

    I’ve edit the command line, and now i’m able to play the video using AVPlayer, but there is no sound...

The most likely reason is either wrong type (e.g. a video option with no video streams) or that it is a private option of some encoder which was not actually used for any stream.
