• Command of FFMPEG to make a video from Image(JPEG) + Audio(.mp3) & Share video in Whatsapp

  22 novembre 2018, par Neel Mevada

  I am trying to create a video .mp4 file from .mp3 audio & .jpeg image.

  I am able to make a video and able to play in Video Players in Android devices.

  But after creation of file when i tried to Share that Video in Whatsapp, at that time it shows a message "The file format not supported".

  I am using below FFMPEG Command :

  "-loop 1 -r 1 -i " + imageFilePath + " -i " + audioFilePath + " -c:v libx264 -crf 27 -tune stillimage -c:a copy -pix_fmt yuv420p -preset ultrafast -shortest " + pathOutputVideo(sectionName);

  And for Sharing video , i am using below Code :

    MediaScannerConnection.scanFile(ShareQuestionAudioActivity.this, new String[]{FfmpegController.pathOutputVideo(qModel.getSectionName().toUpperCase().replaceAll(" ", "_"))},
  
                  null, new MediaScannerConnection.OnScanCompletedListener() {
  
                      public void onScanCompleted(String path, Uri uri) {
  
                          Intent shareIntent = new Intent(android.content.Intent.ACTION_SEND);
  
                          shareIntent.setType("video/*");
  
                          shareIntent.putExtra(Intent.EXTRA_STREAM, Uri.parse(FfmpegController.pathOutputVideo(qModel.getSectionName().toUpperCase().replaceAll(" ", "_"))));
  
                          startActivity(Intent.createChooser(shareIntent, "Share Question"));
  
                      }
  
                  });

  From this Link I found that i need to use H264 + AAC. but still not able to share video with supported file format

• Create animation video or applying different effect on video from set of images [on hold]

  9 janvier 2016, par Mehul Dudhat

  I tried with FFmpeg but it’s not showing any effect with created video.

  I tried below command with FFmpeg lib :

  ffmpeg -f image2 -r 1/5 -i /&lt;<dir path="path">>/img/img%d.jpg -vcodec libx264 /&lt;<dir path="path">>/output_video.mp4
  
  </dir></dir>

  The image generated video :

  Is there any other library available to add effect or animation on video during the creation from set of images ?

  I would like to give this type of animation or effect :

• FFmpeg for automatic video generation from images ?

  22 janvier 2018, par Dionisis K

  I want to implement an automatic video generation from images, like facebook’s anniversary video. And I would also like to add some filters. I’ve been searching a lot and read FFmpeg’s documentation which is pretty amazing.

  In the future I want to have 10-20 "bashscripts" with different filters leading to different themes (e.g. fade-in, zoom, overlay images, left-to-right, etc..)

  So my biggest concern is having an interface which offers readable code and provides scalability. Since ffmpeg is a bashscript i searched for a wrapper

  There are wrappers in

  • https://github.com/PHP-FFMpeg/PHP-FFMpeg for php ,which doesn’t support image convertion to videos and complex filters .
  • https://github.com/fluent-ffmpeg/node-fluent-ffmpeg which looks promising but also difficult to go with complex filters
  • and https://github.com/kkroening/ffmpeg-python for python.I think that it s pretty good

  Are there any other wrappers worth to check ?
  Would you recommend something from the above ?
  Is there any pros and cons using a specific programming language for this particular case ?
  Is there anything else i should bear in mind before I make a decision ?
