  • MediaSPIP 0.1 Beta version

    25 avril 2011, par

    MediaSPIP 0.1 beta is the first version of MediaSPIP proclaimed as "usable".
    The zip file provided here only contains the sources of MediaSPIP in its standalone version.
    To get a working installation, you must manually install all-software dependencies on the server.

  • Multilang : améliorer l’interface pour les blocs multilingues

    18 février 2011, par

    Multilang est un plugin supplémentaire qui n’est pas activé par défaut lors de l’initialisation de MediaSPIP.
    Après son activation, une préconfiguration est mise en place automatiquement par MediaSPIP init permettant à la nouvelle fonctionnalité d’être automatiquement opérationnelle. Il n’est donc pas obligatoire de passer par une étape de configuration pour cela.

  • HTML5 audio and video support

    13 avril 2011, par

    MediaSPIP uses HTML5 video and audio tags to play multimedia files, taking advantage of the latest W3C innovations supported by modern browsers.
    The MediaSPIP player used has been created specifically for MediaSPIP and can be easily adapted to fit in with a specific theme.
    For older browsers the Flowplayer flash fallback is used.
    MediaSPIP allows for media playback on major mobile platforms with the above (...)

  • FFmpeg - downmixing FLAC 6.1 to AAC 5.1

    7 juillet 2014, par Martijn

    I can’t seem to figure out how to do this. I’ve been staring at these commands :
    https://trac.ffmpeg.org/wiki/AudioChannelManipulation

    But to no avail. It’s a tad above my level, sadly. Here’s the ffmpeg -i output for the video in question :

    As you can see, one of the streams is a FLAC 6.1 stream. I wanted to convert that to AAC, and I know how to do that, basically like this :

    ffmpeg -i "input.mkv" -codec:v copy -codec:a aac -strict -2 -b:a 320k -f matroska "output.mkv"

    But apparently AAC doesn’t support 6.1 audio :

    ...
    
[aac @ 03b26860] Unsupported number of channels: 7
    
Output #0, matroska, to 'd:\Movies\[Coalgirls]_Spirited_Away_(1920x1038_Blu-ray_FLAC)_[92372194].aac.mkv':
    
    Stream #0:0(jpn): Video: h264, yuv420p10le, 1920x1038 [SAR 1:1 DAR 320:173], q=2-31, 23.98 fps, 90k tbn, 1k tbc (default)
    
    Stream #0:1(jpn): Audio: aac, 0 channels, 128 kb/s (default)
    
    Metadata:
    
      encoder         : Lavc55.67.100 aac
    
    Stream #0:2(eng): Subtitle: ssa, 128 kb/s (default)
    
    Metadata:
    
      encoder         : Lavc55.67.100 ssa
    
Stream mapping:
    
  Stream #0:0 -> #0:0 (copy)
    
  Stream #0:1 -> #0:1 (flac (native) -> aac (aac))
    
  Stream #0:9 -> #0:2 (ssa (native) -> ssa (native))
    
Error while opening encoder for output stream #0:1 - maybe incorrect parameters such as bit_rate, rate, width or height

    That’s fine, so I wanted to downmix it to 5.1 and encode as AAC. But I can’t seem to work out how to. Any advice ?

  • configure : Use pkg-config for libdc1394 discovery

    22 février 2015, par Vittorio Giovara
    configure : Use pkg-config for libdc1394 discovery

    Since not all systems need the libraw1394 dependency, let pkg-config
    
provide the list of libraries actually needed.
    

    The libdc1394-2.pc file has been included since version 2 (2008-01-05),
    
so it should be safe to use.

  • Catch if the Java proccess crashed

    17 janvier 2012, par VSheyanov

    I run java process to convert video using ffmpeg.exe.

    Runtime rt = Runtime.getRuntime();
    
String cmd = FFMPEGFULLPATH + " -y -i " + '"' + mpeg4File + '"' + " -vcodec libx264 -vsync 2 " + '"' + H264file + '"';
    

    
Process pr = rt.exec(cmd);
    

    
ThreadedTranscoderIO errorHandler = new ThreadedTranscoderIO(pr.getErrorStream(), "Error Stream");
    
errorHandler.start();
    
ThreadedTranscoderIO inputHandler = new ThreadedTranscoderIO(pr.getInputStream(), "Output Stream");
    
inputHandler.start();
    

    
try {
    
      pr.waitFor();
    
} catch (InterruptedException e) {
    
      LiveApplication.logger.info("Some shit happens during convertation 2 ");
    
      throw new IOException("UseTranscoderBlocking - Run_FFMPEG - process interrupted " + e);                  
    
}

    But when the process started, sometimes especially with big files, but not always i get this windows message :

    enter image description here

    This happens only on Windows server 2008 and didn't happened on Windows 7.

    I have 2 questions :

    1. Why this process fails ?
    2. Can I catch this fail in Java, close
      this window and continue thread execution (maybe I'll restart this
      proccess).

    Thanks !
