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)

If you want to clone an svn repository with git-svn but don't want it to push all the existing branches, here's what you should do.

• Clone with git-svn using the -T parameter to define your trunk path inside the svnrepo, at the same time instructing it to clone only the trunk:

  git svn clone -T trunk http://example.com/PROJECT

• If instead of cloning trunk you just want to clone a certain branch, do the same thing but change the path given to -T:

  git svn clone -T branches/somefeature http://example.com/PROJECT

To get your Home and End keys working properly on Mac OS X (Tiger and up, including Mavericks), simply open the Terminal and do this:

$ cd ~/Library
$ mkdir KeyBindings
$ cd KeyBindings
$ vi DefaultKeyBinding.dict

Put these lines in that file, including the curly braces:
