    20 juin 2017, par jimmy

    I have a video with 00:01:41.46 play time,and transcode it perfect with ffmpeg-2.1.1,but when I upgrade FFmpeg version to 3.3.2 and compile it with the same compile option and same transcode option as 2.1.1 version used, I got a video with 00:03:21.82 long, I played that video to see what was added after 1:41.46, and find that it just repeat the video from the beginning with no audio, I find out no idea to this issue, it seems to be a bug that FFmpeg introducing, anyone help me !

    here is the log that I had transcoded with ffmpeg 3.3.2 :

    ffmpeg -i natural.mp4 -c:v libx264 -c:a copy output.mp4

  • 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
