• Evolution #2621 : ergonomie du gestionnaire de plugins

  24 octobre 2014, par b b

  Super, merci pour ces changement cedric :)

  Petite remarque, je pense qu’il serait mieux de ne pas afficher les plugins verrouillés par défaut. Même s’il ne faut qu’un clic pour les masquer, je ne pense pas qu’il soit utile de montrer tout de suite ces plugins à l’utilisateur puisqu’il ne peut pas agir sur ceux-ci.

  Autre point moins important, pensez-vous qu’il faille afficher les plugins obsolètes par défaut ? Je trouve qu’ils polluent un peu la liste affichée étant donné qu’on ne peut pas les activer.

  D’autres avis ?

• x264 library speed - Altivec vs SSE2 -

  25 février 2013, par Omer Merdan

  I have simple cheap dualcore intel-3ghz-debian and access to super-expensive powerPc7-Aix.

  And after few days of strugle, i compiled libx264 and tested it on both computers :

  1. GCC : library x264 on intel (with SSE2 capabilities) and
  2. GCC on 16 core powerPc (with altivec).

  ... and result is that cheap intel is x2 times faster ! (with altivec disabled, intel is 10x times faster)

  My question : is this normal ?
  Does all other powerPC-users have same results ? Can powerPc-altivec-optimisation of x264 library work at same speed with intel... or MMX/SSE optimisation is officially at least 2 times faster for this library ?

  I am not interested in multi-thread options. Number of cores and threads are irrelevant. Just simple one-thread x264 encoding with default "medium preset" using rawvideo as source, sse vs altivec.

  Maybe native Aix XLC compiler provide better results ? (i managed only gcc to work)

  ... mac-powerpc-users maybe know something about this.

• Getting message -> Invalid data found when processing input

  19 novembre 2012, par user1726619

  I want to use ffmpeg lib in my library.For that purpose,i have successfully compiled it.But when i try to execute any command,i am getting this message :

  Invalid data found when processing input.

  I don't know whats the reason behind it.This is the code :

  public class Videokit extends Activity {
  
      String FilePath;
  
      String OutPut;
  
      Context mycontext;
  
      Videokit vk ;
  
      static 
  
      {
  
          System.loadLibrary("videokit");
  
      }
  
  
  
      public native void run(String[] args);
  
  
  
      public void onCreate(Bundle savedInstanceState) {
  
          super.onCreate(savedInstanceState);
  
          setContentView(R.layout.main);
  
          FilePath =Environment.getExternalStorageDirectory().toString()+"/output.3gp";
  
          try {
  
              ffmpegrun();
  
          } catch (IOException e) {
  
              // TODO Auto-generated catch block
  
              e.printStackTrace();
  
          }
  
      }
  
  
  
      public String ffmpegrun() throws IOException
  
      {
  
          boolean success=false;
  
          File folder = new File(Environment.getExternalStorageDirectory().toString() + "/image-%3d.jpeg");
  
          File file = new File(FilePath);
  
          System.out.println("filepath exists at:"+file.getAbsolutePath());
  
          if (!folder.exists()) {
  
              success = folder.mkdirs();
  
  //              Toast.makeText(mycontext,"outfile.mp4 exists at"+folder.getAbsolutePath(),Toast.LENGTH_LONG).show();
  
               OutPut = folder.getAbsolutePath();
  
          }
  
          System.out.println("outfile.flv exists at:"+folder.getAbsolutePath());
  
          run(new String[]{
  
                  "ffmpeg",
  
                  "-i",
  
                  FilePath,
  
                  "-r 1", 
  
                   "-f",
  
                   "image2",
  
                   "image-%3d.jpeg"
  
          }); 
  
          return OutPut;
  
      }
  
  }

  This is the log :
