• Anomalie #3017 : Gestion des versions de plugins

  20 avril 2020, par b b

  RastaPopoulos ♥ a écrit :

  Mise à jour de la maquette, avec un container, trop grand mais de toute façon pour tester c’est bien de se mettre en affichage responsive et voir dans tous les cas, vu que 3.3 est semi-responsive maintenant.

  Merci, mais je pense que la maquette est encore trop large pour refléter la "réalité", 1140px pour la colonne de contenu de l’espace privé c’est possible sur un écran 32" pit-être :p

  Et surtout comme demandé avec un plugin qui encore plus de mises à jour possibles : corrective et mêmes DEUX majeures (ça peut très bien arriver). Cela dit, c’est bien que ça marche comme ça, mais avoir absolument tout ça à la fois ça n’arrivera à peu près jamais. :)

  C’est les débordements provoqués par ce type d’exception qu’il faudra qu’on arrive à bien prendre en charge, car ça fait passer un ensemble de boutons sur deux lignes cf capture ci-jointe.

• Writing Live-Multimedia-Application using OpenGL & Co. saving output to disc [closed]

  21 janvier 2013, par user1997286

  I want to write an application that does the following thing :

  • Getting Commands via ArtNET (DMX over Ethernet, a Control Protocol) for each object (called Layer)
  • each Layer could be one of the following : Live Camera Stream, Movie, Image
  • each layer could be translated, rotated or stretched
  • on each layer I can set filters (Like a Kaleidoscope Effect, Blur, Color Correction, etc.)
  • the rsulting video-stream is in the 3d-space
  • I want to display each part of the image on one Projector (in total up to 3 ones) using a TripleHead2GO (3 Projectors display a different region of my DVI-Output). Each Projecector-Image should have own Soft-Edge and Keystone parameters.
  • the resulting image will also be shown on a Preview-Screen with some Information overlay.

  I think all that should be possible with opengl and openal (for the movie audio)

  I think I'll use C++, OpenGL for Graphics, OpenAL for Audio, if needed ffmpeg for Video conversion, Ubuntu/Debian as OS.

  The software is used to do Multimedia-Shows on Concerts including Cameras & Co.

  All that should happen Live (On a FullHD output), Having i7 3770, GLX 670 and 16GB of Ram for at least 8 Layers. (4 Live-Images at once + Some Overlays like the Actors Name and some Logos)

  But now comes the question.

  Is it also Posible to do the following with that setting :

  • Writing the output Image with all the 3d translations to a Movie File (To Master a DVD later) with Audio
  • Mixing Audio from different Inputs & Files (Ambience Mics, Signal from the Sound Mixer, Playbacks from my own application) to more than one Mix (eg. one Mix for the Recording, one Mix for Live)
  • Stream that Output Complete or in Parts (e.g. the left Part of the Image) over the Network (For example, Projector 1 is near the Server, so I connect it using DVI, Projector 2+3 is connected to a Computer that receives the streams for that two projectors (with soft edge on each stream) and Screen 4 is outside the Concert Hall and shows the complete Live-Stream.
  • What GUI-Framework should I use for that ?
  • is it perhaps event performant enough to use Java for that ?
  • is it posible to use that mechanism for just rendering (eg. I have stored the cut points on Disc and saved every single camera stream to change some errors later or cut out some parts)

• java.lang.UnsatifiedLinkError : no jniavutil in java.library.path using JavaCV FFmpegFrameGrabber

  31 mars 2015, par Noah Lutz

  I’m writing a program that is using JavaCV to grab frames from a stream. Its trying to use FFmpegFrameGrabber to capture the frames but when I try to run it, I get an UnsatisfiedLinkError.

  Here is the code :

  FrameGrabber frameGrabber;
  
      try{
  
          frameGrabber = new FFmpegFrameGrabber("http://devimages.apple.com/iphone/samples/bipbop/bipbopall.m3u8");
  
          frameGrabber.start();
  
  
  
          while(true){
  
              video.addFrame(new Frame(frameGrabber.grab()));
  
              System.out.println(video.getLength());
  
          }
  
      }catch(Exception e){
  
          e.printStackTrace();
  
      }

  And here is the stack trace :

  I have both OpenCV and FFmpeg installed and I followed the instructions for the manual installation of JavaCV on their github page.

  Thanks for your help.
