• Anomalie #2788 : Critères optionnels et passage automatique de #ENV dans les modèles

  8 juillet 2012, par jluc -

  La question est donc "comment faire un critère conditionnel qui ne prenne que les arguments passés explicitement en paramètre lors de l’appel du modèle". Vu que ceux ci sont les seuls à pouvoir être récupérés également par #ENVarg/nomdelargument, la question est "comment boucler sur l’environnement (...)

• Installing faad library for ffmpeg through Homebrew on mac OS X Lion

  14 décembre 2011, par alex

  Following up with my previous question, I decided to give Ffmpeg a try and installed it on my Mac with Homebrew.

  I am now trying to follow this tutorial and use the linked script. But can't make/install the script. I first corrected a small bug (replaced CODEC_TYPE_AUDIO, CODEC_TYPE_VIDEO and PKT_FLAG_KEY with AVMEDIA_TYPE_AUDIO, AVMEDIA_TYPE_VIDEO, and AV_PKT_FLAG_KEY respectively in live_segmenter.c). But now, when I run make in the unzipped folder, I get the following warning and error messages :

  gcc -Wall -g live_segmenter.c -o live_segmenter -lavformat -lavcodec -lavutil -lbz2 -lm -lz -lfaac -lmp3lame -lx264 -lfaad -lpthread

  ld: library not found for -lfaad
  
  collect2: ld returned 1 exit status
  
  make: *** [all] Error 1

  I also downloaded the faac/faad libraries from here. When I run make in faac, it says I have nothing to install, but I can't find out how to install faad...

  Would love any help you can offer !

• wrong ffmpeg version for xuggler

  13 décembre 2011, par kerel

  I am trying to get Xuggle working on Ubuntu.
  This is however my first time using a Unix system.

  After installing Xuggle and correcting the PATH files I tried some very simple code from tutorials at the xuggle website. But once I attempt to debug my code, it stops and eclipse says

  Suspended (exeption IllegalArgumentException)

  and refers to line 488 of MediaReader.readPacket()

  After searching possible explanations I found that my FFMPEG version was not the version Xuggle needs. When I test my FFMPEG version from command line with
  $ ffmpeg /invalid/file/ it displays --extra-version='4:0.7.2-1ubuntu1' but according to the xuggle site the --extra-version= should include the word "xuggle". Following their installation procedures does not change anything.

  I downloaded the source code from SVN, which includes a ffmpeg folder. I assume this is the ffmpeg version I need. I have no clue however what to do with this folder.

  question is : how do I get my ffmpeg version to the xuggle compatible ffmpeg version ?
