  • How do I prevent Quality loss in the beginning of a video ?

    25 mars 2012, par Adam Ingmansson

    My company transcodes videos sent in by users (recorder by our own screenrecording software)

    I use FFMpeg to do the work using this command :

     /ffmpeg/ffmpeg -i in.mov -vcodec libx264 -fpre /ffmpeg/ffpresets/libx264-slower.ffpreset   -y out.flv

    The purpose is to prepare the video for viewing in browser.

    The problem is that the first 10, or so, seconds the quality is really poor.

    What can cause this ? and how can i fix it ?

  • 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
