• Conversion does not end using ffmpeg on Android device

  3 février 2016, par Belhaver

  I am trying to make an application with usage of ffmpeg-android-java https://github.com/WritingMinds/ffmpeg-android-java and i have a problem. File conversion just does not end.

  Here is code which i am using :

  try {
  
      // code...
  
          String commandStr = "-y -i /storage/emulated/0/input.mp4 -strict experimental -s " + fileWidth + "x" + fileHeight + " -vcodec libx264 -r 30 /storage/emulated/0/output.mp4";
  
  
  
          ffmpeg.execute(commandStr, new ExecuteBinaryResponseHandler() {
  
              @Override
  
              public void onSuccess(String message) {
  
                  Log.d("FFMPEG success", "");
  
                  // code...
  
              }
  
  
  
              @Override
  
              public void onFailure(String message) {
  
  
  
                  Log.d("FFMPEG failure: ", message);
  
                  // code...
  
              }
  
  
  
              @Override
  
              public void onProgress(String message) {
  
                  Log.d("FFMPEG process: ", message);
  
              }
  
  
  
              @Override
  
              public void onFinish() {
  
                  Log.d("FFMPEG done", "");
  
              }
  
          });
  
      } catch (Throwable e) {
  
          e.printStackTrace();
  
      }

  Here is the output process :

• Installing GPAC's player - Errors

  25 janvier 2016, par VirMarGu

  I am working with Ubuntu 14.04 LTS 64 bits.
  I am trying to compile and install GPAC’s player (Osmo) in its latest version.

  I had an installed version, but I have tried to compile one new and finally, the previous one doesn’t already work fine.

  I have made the following steps :

  1. sudo apt-get install git
  
  
  
  2. git clone https://github.com/gpac/gpac.git
  
  
  
  3. sudo apt-get install subversion make pkg-config g++ zlib1g-dev libfreetype6-dev libjpeg62-dev libpng12-dev libopenjpeg-dev

  dvb-apps libavcodec-extra libavdevice-dev libmozjs185-dev
  
  
  
  4. cd gpac
  
  
  
  5. ./configure

  The output of the previous execution is :

• Convert PNGs to webm video with transparency

  20 septembre 2016, par sebastian

  I would like to use avconv to convert a series of PNG images to a WebM video, preserving transparency.

  I understand that the pixel format used in the output video must support transparency. So I tried :

  $ avconv -framerate 25 -f image2 -i frames/%03d.png -pix_fmt yuva420p output.webm

  Unfortunately, avconv complains :

  Incompatible pixel format 'yuva420p' for codec 'libvpx-vp9', auto-selecting format 'yuv420p'
