complete list of ffmpeg flags / commands
Originall From: Posted 2015-05-29 http://ubwg.net/b/full-list-of-ffmpeg-flags-and-options
This is the complete list that’s outputted by ffmpeg when running ffmpeg -h full.
usage: ffmpeg [options] [[infile options] -i infile]… {[outfile options] outfile}…
Getting help:
-h — print basic options
-h long — print more options
-h full — print all options (including all format and codec specific options, very long)
