• permission denied. ffmpeg tries to process a file located in /data/data/

  30 octobre 2015, par user2326258

  I have such an APP that the users sends a video from the multimedia message(add a video in the message and then the video is copied to /data/data/somewhere). If the user press the video in the file, the message activity passes the video’s uri to another activity which processes the video with ffmpeg.

  I got the video’s file descriptor(fd) by :

  ContentResolver resolver = context.getContentResolver();
  
  fd = resolver.openAssetFileDescriptor(uri, "r");

  and pass fd.getFileDescriptor()to ffmpeg.
  However I got permission denied such that ffmpeg cannot open the file.

  Is there anyway to fix that ?

  Thanks a lot.

• Android - ffmpeg ignore loop after export

  1er juin 2017, par NewUser

  Good day all. I am currently using this FFMPEG library. Here is the command I am running

  String[] s = {"-i" ,mVideoUri.toString(),"-i",newBackgroundBitmap.getPath(),"-filter_complex","[1:v][0:v]scale2ref=iw:ih[ovr][base];[ovr]colorchannelmixer=aa=0.7[ovrl];[base][ovrl]overlay[v]","-map","[v]","-c:v","libx264","-preset","ultrafast",directoryToStore+"/"+lastSaved+mp};
  
  
  
  //mVideoUri.toString() is the selected video
  
  //newBackgroundBitmap.getPath() is a drawn bitmap

  mMediaPlayer also has anchor/loop control points, to ’loop’ the video.(shown in the image below)

  Everything works perfectly, the video is saved perfectly as I suspected.

  But here is where the problem comes, after I saved the video and try to use that video in ANY (even my) editing application, the starting point is messed up, it is hard to put it in words, so here is a image.video control points after export

  REMEMBER THIS ONLY HAPPENS AFTER I EXPORTED THE VIDEO

  ---

  The problem is definitely caused by ffmpeg or ffmpeg command. I have tried forcing the start and end control points ;

  private Runnable updateVideoTime = new Runnable() {
  
      public void run() {
  
  
  
          if (!Activity.this.mMediaPlayer.isPlaying()) {
  
              Activity.this.mMediaPlayer.seekTo(Activity.this.leftPosition);
  
              Activity.this.mMediaPlayer.start();
  
          }

  ---

  No matter what I try I can’t stop the ’progressBar’ from ignoring the starting loop. It could perhaps be the fact that the ffmpeg used in the library is out of date ?

  Has anyone who used ffmpeg(or this library) before dealt with this issue ?

  Any help would be appreciated.
