Note that there is absolutely no substitute for reading the license.
You would not buy a house and have somebody summarize the contract for
you, would you?  So go ahead, read the GPL (v3 in your case) and the GPL
FAQ, it should answer all your questions.

You need to provide the exact same source you used to build your FFmpeg
executable.  Putting a tarball up for download is fine with us.  You
should also note which version of FFmpeg you were using and make any
modifications available.
