Wo can tell me the difference and relation between ffmpeg 、libav and avconv
28 février 2012, par whywhen 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).
Hyper fast Audio and Video encoder
usage: ffmpeg [options] [[infile options] -i infile]... {[outfile options] outfile}...
Use -h to get full help or, even better, run 'man ffmpeg'I found avconv on http://libav.org, I am just perplexed by them
