• Ffmpeg Android add metadata to video

  7 septembre 2016, par msj

  I’m working with android video recording application. I want to add some metadata in recorded video such as Title, Author, Publisher, CoptRight.

  I use following command to edit metadata information.

  ffmpeg -i in.mp4 -metadata title="my title" 
  
               -metadata author="author" 
  
               -metadata Publisher="Publisher"
  
        out.mp4e

  But change only the Title. other meta information cant add to a video using this command.

  Is it possible to change those meta details. if yes, then how to add or change all meta data in a video.

• How to monitor a video file and get an event when it is done and ready after some processing ?

  7 avril 2015, par shivani

  In my application I have a video file which I am giving to a ffmpeg library for compression.
  The compressed file is getting generated in sdcard in the path that I have specified.
  As soon as the complete file is ready in the specified path I want to send the details of the compressed file to the server.
  I am not able to get the instance of when the video file is completely written as the compression part is done by a library attached to my code.

  setCommandComplex(complexCommand);
  
  
  
                  setOutputFilePath(outvidpath);
  
  
  
                  setProgressDialogTitle("Compression");
  
                  setProgressDialogMessage("Depending on your video size, it can take a few minutes..Please Wait..");
  
  
  
                  setNotificationIcon(R.drawable.icon);
  
                  setNotificationMessage("Process is running...");
  
                  setNotificationTitle("Compression");
  
                  setNotificationfinishedMessageTitle("Process Completed");
  
                  // setNotificationfinishedMessageDesc("Click to play demo");
  
                  setNotificationStoppedMessage("Process Failed");
  
                  runTranscoing(); // this is the method where compression is done

  How can I monitor my video file and get an event when it is done and ready after compression ?

  Please help !
