• mov : Free intermediate arrays in the normal cleanup function

  13 janvier 2014, par Martin Storsjö

  mov : Free intermediate arrays in the normal cleanup function
  These arrays are normally freed at the end of mov_read_trak,
  
  but make sure they’re freed in case mov_read_trak returned
  
  early (due to errors) or in case the atoms that allocate arrays
  
  are encountered at some other point than within a trak (which
  
  we don’t have checks against).

• AsyncTask publishProgress() does not update progress ffmpeg android

  7 février 2014, par jay

  I am using ffmpeg commands for processing media files.In doInBackground() method i have started the process and every time i get the duration , time values and grabbing progress using time and duration and send progress to publishProgress(progress).When i tested on google nexus(android 4.4 kitkat) it is updating progress dialog correctly but this won't happen in below android 4.4 devices.It is updating with an eye blink of time after completion of the process.
  Here is my code :

  protected String doInBackground(String... params)  {
  
              // TODO Auto-generated method stub  
  
              try {
  
                  proc = mProcess.start();
  
              } catch (IOException e) {
  
                  // TODO Auto-generated catch block
  
                  e.printStackTrace();
  
              }
  
              processDuration(proc.getErrorStream());
  
  
  
              // Wait for process to exit
  
              int exitCode = 1; // Assume error
  
              try {
  
                  exitCode = proc.waitFor();
  
              } catch (InterruptedException e) {
  
                  Log.e(TAG, "Process interrupted!", e);
  
              }
  
              onExit(exitCode);           
  
              return null;            
  
          }
  
  
  
          private void onExit(int exitCode) {
  
              // TODO Auto-generated method stub
  
              Log.i("exit code >>>>>>>>..", ""+exitCode);
  
          }
  
  
  
          private void processDuration(InputStream errorStream) {
  
              // TODO Auto-generated method stub
  
              Scanner sc = new Scanner(errorStream);          
  
              // Find duration
  
              Pattern durPattern = Pattern.compile("(?<=Duration: )[^,]*");
  
              String dur = sc.findWithinHorizon(durPattern, 0);
  
              if (dur==null) throw new RuntimeException("Could not parse    duration.");          
  
              String[] hms = dur.split(":");
  
              try{
  
                  totalSecs= Integer.parseInt(hms[0]) * 3600 + Integer.parseInt(hms[1]) *  60 + Double.parseDouble(hms[2]);
  
                  Log.i(" progress>>>>>>>>>>>>>",""+totalSecs);
  
              }catch(NumberFormatException e){
  
  
  
              }
  
              Pattern timePattern = Pattern.compile("(?<=time=)[\\d:.]*");
  
              String match= sc.findWithinHorizon(timePattern, 0);             
  
              while (null != (match = sc.findWithinHorizon(timePattern, 0))) {
  
                  hms = match.split(":"); 
  
                  try{
  
                      processedSecs= Integer.parseInt(hms[0]) * 3600 + Integer.parseInt(hms[1]) *  60 + Double.parseDouble(hms[2]);
  
                  }catch(NumberFormatException e){
  
  
  
                  }
  
                  progress = processedSecs / totalSecs;   
  
                  final int finalProgress=(int)(progress*100);
  
                  try {
  
  
  
                      publishProgress(""+finalProgress);
