• “only position independent executables (PIE) are supported”

  3 juin 2015, par Karthikeyan

  I am using FFMPEG support library to convert bunch of images to video. It works fine on earlier version of the lollipop. But in the lollipop it generates the following error. ***error: only position independent executables (PIE) are supported.*** I know the PIE Security restrictions has been changed in lollipop, but i don’t know how to fix it.

  From my knowledge it may have two possible solutions,

  either

  we need to relocate the FFMPEG library assets to the SDCard and we have to refer them from our coding, if this is the answer what are all the steps to be followed ?

  or

  Is there any update in the FFMPEG library for android lollipop.

  If both are wrong can you provide me with the proper solution.

  Many thanks...

  Here is my code

     try {
  
              String[] ffmpegCommand = {"/data/data/com.mobvcasting.mjpegffmpeg/ffmpeg", "-r", ""+p.getPreviewFrameRate(), "-b", "1000000", "-vcodec", "mjpeg", "-i", 
  
                      Environment.getExternalStorageDirectory().getPath() + "/req_images/frame_%05d.jpg", Environment.getExternalStorageDirectory().getPath() + "/req_images/video.mov"};
  
  
  
              ffmpegProcess = new ProcessBuilder(ffmpegCommand).redirectErrorStream(true).start();            
  
  
  
              OutputStream ffmpegOutStream = ffmpegProcess.getOutputStream();
  
              BufferedReader reader = new BufferedReader(new InputStreamReader(ffmpegProcess.getInputStream()));
  
  
  
              String line;
  
  
  
              Log.v(LOGTAG,"***Starting FFMPEG***");
  
              while ((line = reader.readLine()) != null)
  
              {
  
                  Log.v(LOGTAG,"***"+line+"***");
  
              }
  
              Log.v(LOGTAG,"***Ending FFMPEG***");
  
  
  
  
  
          } catch (IOException e) {
  
              e.printStackTrace();
  
          }
  
  
  
          if (ffmpegProcess != null) {
  
              ffmpegProcess.destroy();        
  
          }

• ffmpeg mkv to mp4 including subtitles

  1er février 2017, par user3677559

  Want to convert mkv files to mp4 (h264, mp3 and subtitles). I checked the video files with ffprobe. For the output

  Stream #0:2(ger) : Subtitle : dvb_subtitle (default)

  The subtitles are included in the converted video with following ffmpeg command.

  ffmpeg -i movie.mkv -c:v libx264 -c:a libmp3lame  -b:a 320k -c:s dvd_subtitle  converted.mp4

  But for the output :

  Stream #0:3(ger) : Subtitle : subrip (default)

  The command isn’t working. There is no error message and the resulting video includes a subtitle stream, but no subtitles are showed. I tried also with the subtitle encoding mov_text and copy, but no luck. Following the output from console :
