• Crash while loading JNI Library

  23 juin 2016, par Amira Elsayed Ismail

  I am using ffmpeg4android_lib to compress video in my android application, it is working in all devices but it does not work in s6 edge and s7 edge

  my code as following :

  String inputFile = FileManager.getInstance().getRealPathFromVideoUri(context, video);
  
                      Log.i("INPUT FILE PATH", inputFile);
  
  
  
                      LoadJNI vk = new LoadJNI();
  
                      try {
  
                          String workFolder = context.getApplicationContext().getFilesDir().getAbsolutePath();
  
                          String outputFile = FileManager.getInstance().getFileFullName(ForSaleConstants.VIDEO_FOLDER,
  
                                  String.format(ForSaleConstants.VIDEO_NAME_FILE_FORMAT,
  
                                          ForSaleConstants.VIDEO_NAME_FILE_NAME_PREFIX, System.currentTimeMillis()));
  
                          String complexCommand[] = {
  
                                  "ffmpeg", "-y"
  
                                  , "-i", inputFile
  
                                  , "-strict", "experimental"
  
                                  , "-s", "320x240"
  
                                  , "-r", "25"
  
                                  , "-aspect", "4:3"
  
                                  , "-ab", "48000"
  
                                  , "-ac", "2"
  
                                  , "-vcodec", "mpeg4"
  
                                  , "-movflags", "+faststart"
  
                                  , "-ar", "22050"
  
                                  , "-b", "2097k"
  
                                  , outputFile};
  
                          vk.run(complexCommand, workFolder, context.getApplicationContext());
  
                          Log.i("OUTPUT FILE PATH", outputFile);
  
                          return outputFile;
  
                      } catch (Throwable e) {
  
                          ForSaleServerManager.getInstance().logAndroidError("Couldn't compress video file");
  
                          return null;
  
                      }

• How can I apply complex filters more than once with different parameters while avoiding "too many inputs" errors

  15 mai 2019, par Hugh Walxet

  I’m trying to apply the displace complex filter more than once in a video, at specific intervals with no proportional relationship. In each instance, I want to apply the displace filter with slightly different parameters. If I list it twice in the commands for the complex_filter, I get an error saying I have too many inputs.

  I might as well ask, separately, how I could apply the same filter with the same parameters more than once in a video, without re-iterating the same filter more than once in the command line. Put differently, how do I run a filter as specific times without writing the command several times sequentially, each with a different trigger time ?

  C:\Users\Me>ffmpeg -i c:\users\Me\desktop\house2.mp4 -i c:\users\Me\desktop\house3.mp4 -i c:users\Me\desktop\house4.mp4 -filter_complex "shuffleframes=enable='between(t,21,27)':mapping=0 9 2 1 10 5 8 6 7 4 3, shuffleframes=enable='between(t,3,7)':mapping=0 4 9 1 10 5 8 6 2 7 4 3, shuffleframes=enable='between(t,15,19)':mapping=0 6 2 1 10 5 8 3 7 4 9, [0][1][2] displace=enable='between(t,9,10)':edge=wrap, [0][1][2] displace=enable='between(t,20,21)':edge=smear" c:\users\Me\desktop\houseglitch.mp4
