• ffmpeg library rotates video after compression Android

  14 septembre 2016, par Leo Wiki

  I’m using ffmpeg library for video file compression in my Android project.

  To implement ffmpeg I refereed this link. Compression is working fine but after compression process this library rotating my video 90 degree which I don’t want to be happen. I googled a lot but yet not reach to solution which can tell me how to stop rotating the video. For video compression I’m using the following command—

  ffmpeg -y -i /sdcard/videokit/in.mp4 -strict experimental -vf transpose=1 -s 160x120 -r 30 -aspect 4:3 -ab 48000 -ac 2 -ar 22050 -b 2097k /sdcard/videokit/out.mp4

  Please let me know if I can provide more information to you.

  Thank you.

• Android ffmpeg library use

  26 août 2016, par m.skolimowski

  I’m pretty new to use of ffmpeg library. I used this http://writingminds.github.io/ffmpeg-android-java/ to add library to my android studio project. It works well when I run the command -version or -devices
  However when I try any command with -i beginning like for example -i video.avi I get the error :

  Am I doing something wrong ? ANybody have idea why basic command like "-i" doesnt work ?

• Video compressed using ffmpeg-android-java library, does not play on Web browsers

  27 juin 2016, par Jay Donga

  I am capturing video using default camera in Android and compressing it using ffmpeg-android-java library.

  After successful compression, video is playing in MXPlayer app, but fails to play in Web browsers like Google Chrome, Firefox.

  What can be the reason ?

  I have shared my compression logic. What changes can I make here so it can play on browsers ?

  String[] str=new String[]{"-y" ,"-i",sourceFilename,"-strict","experimental","-s", "160x120","-r","25", "-vcodec", "mpeg4", "-b", "150k", "-ab","48000", "-ac", "2", "-ar", "22050", destinationFilename};
  
  
  
  try{
  
              FFmpeg ffmpeg = FFmpeg.getInstance(getActivity());
  
              ffmpeg.execute(str, new ExecuteBinaryResponseHandler() {
  
  
  
                  @Override
  
                  public void onStart() {}
  
  
  
                  @Override
  
                  public void onProgress(String message) {
  
                      Log.e("onProgress",message);
  
                  }
  
  
  
                  @Override
  
                  public void onFailure(String message) {
  
                      Log.e("onFailure",message);
  
                  }
  
  
  
                  @Override
  
                  public void onSuccess(String message) {
  
                      Log.e("onSuccess",message);
  
                  }
  
  
  
                  @Override
  
                  public void onFinish() {}
  
              });
  
          }  catch (FFmpegCommandAlreadyRunningException e) {
  
              e.printStackTrace();
  
          }
