Comment (by Timothy_Gu):

 Replying to [comment:3 ctsang]:
 > OK, we can host the exact source code on our own site but do we use the
 LGPLv3 or GPLv3 licence? I'm really not sure what the difference is for
 our purpose and we simply used the binaries from the Zeranoe site.

 The LGPL allows you to use FFmpeg in a non-GPL software (like yours),
 while GPL '''does not'''. Zeranoe builds are GPL, so you can't use Zeranoe
 builds anyway.

 > In our copyright information, we do mention the use of FFmpeg and its
 libraries but not in the exact words as described in that legal documents.
 The legal.html only refers to LGPL so what is the checklist for GPLv3? We
 will amend it as soon as we know what it is.

 Again, you are '''not allowed''' to use GPL at all, unless you are GPLing
 your program.

 The page we linked applied only for LGPL, because that is the only license
 you are allowed to use FFmpeg.
 So what you need to do:

 Option 1:
 1. Open source and GPL your application.
 2. Nothing.

 Option 2:
 1. Make a customized LGPL build.
 2. Follow the checklist on http://ffmpeg.org/legal.html
