• Android Merging two or more videos from the List to a single synchronised video

  18 août 2017, par Alok Kumar Verma

  I’ve an activity which has the certain videos inside my recyclerview. I’ve one button which takes you to the next activity which has the VideoView.
  Now the main task is to merge the videos to single synchronous video and that video file will be played in the video View.

  The mapping is like -> EditVideoActivity.java (List of Videos in recyclerview) -> Processing the video merging into one -> saving somewhere -> the merged video getting played.

  I’ve researched on several sites about this and came to know that two things are available for this, these are :

  1. FFMPEG

  2. MP4Parser

  Now I’ve followed some questions on StackOverflow about this :

  1. FFMPEG Usage getting problem in Orientation : This doesn’t serve my motive. As this guy has used some coding.
  2. Mp4Parser : They have moved their site to Github but I got 504 gateway timeout so no guidance for that.

  Developer Android has MediaCodec and I went there it was quiet complex

  I’m sending out the data in string format or i must say the video path in array format to other activity and is working fine.

  I’ve done some homework what I did is just in media player I appended the videos. But I have to merge the videos and then it has to be played inside the videoplayer.

  1. When the button is clicked it merges the videos and saves it in a storage specified

  The same videos is now played in videoplayer

  EditVideo.java from where the data is passed from the press of the button

  audioButton.setOnClickListener(new View.OnClickListener() {
  
                    @Override
  
                    public void onClick(View view) {
  
                        //the position of the video
  
                        videoPosition = selectedVideo;
  
  
  
                        if(videoPosition != null){
  
                            Intent intent = new Intent(EditVideoActivity.this, AudioActivity.class);
  
                            intent.putExtra("videoData",videoPosition);
  
                            Log.e("VIDEO_SENT_DATA=======", videoPosition);
  
                            startActivity(intent);
  
                        }else
  
                            Toast.makeText(EditVideoActivity.this,"You have not selected any video",Toast.LENGTH_LONG)
  
                                    .show();
  
                    }
  
                });

  from here the data is getting passed, I’m working on how to merge the videos with the press of the above button

  And PreviewActivity.java is the page where the videoView is there to be played (the merged files)

  I’ve done this : Appending the videos in onCreate()

  //getting the passed value from the previous activity
  
      Bundle extras = getIntent().getExtras();
  
      final ArrayList<string> videoReceived = extras.getStringArrayList("videos");
  
      Log.e("VIDEO_RECEIVED",videoReceived.toString());
  
  
  
      mVideoPlayer.setVideoPath(String.valueOf(videoReceived.get(0)));
  
      mMediaController = new MediaController(this);
  
      mMediaController.setMediaPlayer(mVideoPlayer);
  
      mVideoPlayer.setMediaController(mMediaController);
  
      mVideoPlayer.setBackgroundColor(Color.TRANSPARENT);
  
      mVideoPlayer.requestFocus();
  
      mVideoPlayer.start();
  
      Log.e("VIDEO_SIZE===",String.valueOf(videoReceived.size()));
  
      mVideoPlayer.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
  
          @Override
  
          public void onCompletion(MediaPlayer mediaPlayer) {
  
  
  
              if( currentIndex &lt; videoReceived.size()){
  
                  String uri = String.valueOf(videoReceived.get(currentIndex));
  
                  mVideoPlayer.setVideoPath(uri);
  
                  mVideoPlayer.start();
  
                  currentIndex++;
  
              }
  
          }
  
      });
  
  </string>

• Multiple files in JW Player 6 not working

  18 octobre 2013, par Dvex

  Use version 6 JW Player. I'm transforming my videos using FFMPEG to MP4, FLV and WebM.

  When the videos are intended to be played, it does not and I have the following error :

  Error playing media: 
  
  MediaError
  
  code: 4
  
  __proto__: MediaError
  
  MEDIA_ERR_ABORTED: 1
  
  MEDIA_ERR_DECODE: 3
  
  MEDIA_ERR_ENCRYPTED: 5
  
  MEDIA_ERR_NETWORK: 2
  
  MEDIA_ERR_SRC_NOT_SUPPORTED: 4
  
  constructor: function MediaError() { [native code] }
  
  __proto__: Object
  
   jwplayer.js?muokxc:4
  
  CAPTIONS([object Object]) jwplayer.js?muokxc:4
  
  CAPTIONS([object Object]) 

  In Firefox I have the error : "The file can not be decoded".
  This scenario only happens on my server. But on localhost, does not happen. The videos can be played normally.

  What is it that is happening ?

  My JS code to initialize the JW Player is :

  jwplayer('jwplayerjw-player').setup({
  
  "aspectratio":"16:9",
  
  "playlist":[{
  
  "image":"http://mydomain.com/system/files/videos/thumbnails/48/thumbnail-48_0002.png",

  {"file":"http://mydomain.com/system/files/videos/converted/48/loop_2_mp4_1381794691.mp4"},
  
  {"file":"http://mydomain.com/system/files/videos/converted/48/loop_2_webm_1381794705.webm"}]}],
