  • La sauvegarde automatique de canaux SPIP

    1er avril 2010, par

    Dans le cadre de la mise en place d’une plateforme ouverte, il est important pour les hébergeurs de pouvoir disposer de sauvegardes assez régulières pour parer à tout problème éventuel.
    Pour réaliser cette tâche on se base sur deux plugins SPIP : Saveauto qui permet une sauvegarde régulière de la base de donnée sous la forme d’un dump mysql (utilisable dans phpmyadmin) mes_fichiers_2 qui permet de réaliser une archive au format zip des données importantes du site (les documents, les éléments (...)

  • Streaming jpegs live to iphone app

    14 février 2012, par Raven

    Im progressing through taking the depth camera feed from my kinect and streaming it to my iphone app. I have got to stage of being able save jpegs for every frame created from the kinect depth image (30 fps) and save them to the local disk. I have than been able to convert this to mpeg with ffmpeg.

    My question is now how can I view this live on my iphone ? Basically I want to view it live on the iphone as you are seeing it coming from the kinect.

    Should I use http live streaming and use the segmenter to use apples HttpLiveStreaming functionality ? Or can I stream the raw jpeg image files up in some way as they are saved to disk and than just cycle the images on the phone as they go ?

    Im wondering how video conferencing is achieved on the iphone (facetime/skype etc) ? because I'd prefer that it wasnt played inside the video player, just want to display live content on the screen as it happens.

    Any ideas ? Thanks in advance

  • Why can’t I run the ffmpeg executable stored in /mnt/sdcard ?

    18 novembre 2024, par user2193172

    I managed to compile the ffmpeg Static build. But when I am trying to call the ffmpeg command line I get a Java IOException : No such file or Directory.

    



    My code is as follows :

    



    public void merge_video(View view){

    if(ffmpeg_file.exists()){
          Log.d(null, "ffmpeg exists");
      }else{
          Log.d(null, "Could not locate ffmpeg in the folder");
      }

      File file1 = new File("/mnt/sdcard/com.ffmpeg_test/VID_3_25_2013_12_22.mp4");
      if(file1.exists()){
          Log.d(null,"File 1 exists");
      }
      File file2 = new File("/mnt/sdcard/com.ffmpeg_test/VID_3_25_2013_12_28.mp4");
      if(file2.exists()){
          Log.d(null,"File 2 exists");
      }

      String[] ffmpegCommand = new String[5];
      ffmpegCommand[0] = "/mnt/sdcard/com.ffmpeg_test/ffmpeg";
      ffmpegCommand[1] = "-i";
      ffmpegCommand[2] = "concat:/mnt/sdcard/com.ffmpeg_test/VID_3_25_2013_12_22.mp4|/mnt/sdcard/com.ffmpeg_test/VID_3_25_2013_12_28.mp4";
      ffmpegCommand[3] = "copy";
      ffmpegCommand[4] = "/mnt/sdcard/com.ffmpeg_test/output.mp4";  

      try {
          Process ffmpegProcess = new ProcessBuilder(ffmpegCommand).redirectErrorStream(true).start();

          String line;
          BufferedReader reader = new BufferedReader(new InputStreamReader(ffmpegProcess.getInputStream()));
          Log.d(null, "*******Starting FFMPEG");

          while((line = reader.readLine())!=null){

              Log.d(null, "***"+line+"***"); 
          }
          Log.d(null,"****ending FFMPEG****");

    } catch (IOException e) {
        e.printStackTrace();
    }
  }
