    Cependant, il est possible et facile d’autoriser les visiteurs à avoir accès à ces documents et ce sous différentes formes.
    Tout cela se passe dans la page de configuration du squelette. Il vous faut aller dans l’espace d’administration du canal, et choisir dans la navigation (...)

  • Who can tell me the difference and relation between ffmpeg, libav, and avconv

    25 septembre 2014, par why

    when I run ffmpeg on Ubuntu, it shows :

    $ ffmpeg 
    
ffmpeg version v0.8, Copyright (c) 2000-2011 the Libav developers
    
  built on Feb 28 2012 13:27:36 with gcc 4.6.1
    
This program is not developed anymore and is only provided for compatibility. Use avconv instead (see Changelog for the list of incompatible changes).

    or it shows (depending on Ubuntu version) :

    $ ffmpeg
    
ffmpeg version 0.8.5-6:0.8.5-0ubuntu0.12.10.1, Copyright (c) 2000-2012 the Libav developers
    
  built on Jan 24 2013 14:49:20 with gcc 4.7.2
    
*** THIS PROGRAM IS DEPRECATED ***
    
This program is only provided for compatibility and will be removed in a future release. Please use avconv instead.

    I found avconv on http://libav.org, I am just perplexed by them

  • FFmpeg AVI to MP4 preserves sound, but not images [migrated]

    21 février 2013, par user1711384

    Working with FFmpeg at a conversion (any file to MP4 (H.264/AAC)) :

    ffmpeg -y -i testdatei.avi -i logo.jpg -filter_complex overlay=15:15,scale=-1:720 -c:v libx264 -profile:v baseline -preset medium -b:v 880k -g 10 -pass 1 -an -f mp4 -movflags faststart /dev/null
    
ffmpeg -y -i testdatei.avi -i logo.jpg -filter_complex overlay=15:15,scale=-1:720 -c:v libx264 -profile:v baseline -preset medium -b:v 880k -g 10 -pass 2 -c:a libfdk_aac -b:a 128k -movflags faststart xxx.mp4 2>&1

    With MPEG and WMV file it's working. With two different AVIs it didn't work. Logfiles from path 1 aren't generated and output 1 is empty, output 2 of course generates an error.

    After removing -profile:v baseline in both commands, the video file is successfully generated, but it's not possible to play it in JW Player (sound yes, but no image).

    This is the result of the first command :
