Check whether sfeMovie could rely on Zeranoe builds

[Ceylo]

Investigate on whether Zeranoe builds could be used on Windows ( http://ffmpeg.zeranoe.com/builds/ ):

• it must provide both the .lib and .dll for a specific FFmpeg release

[bluekirby0]

Shared import libraries are provided in the "dev" packages, and the associated DLLs are provided in the "shared" packages. Both packages are provided for any revision he provides.

The only problem is these are all GPL3 builds so unless you make a special request of Zeranoe they will be unusuable for anyone wishing for the leniency of the LGPL license for use with their own code. He appears to be charging for custom builds now.

Last time I check Zeranoe builds I didn't pay attention to the licence but it looks like things changed :)
He doesn't stay whether he charges for custom builds but it may indeed be the case.

So if we consider GPL3 only builds, this still does have the advantage for the user not to have to install MinGW and build FFmpeg, if the project if only personal or under GPL. Considering this, I don't know if it's interesting enough to support...

To users that could be interested in the result of this task: are the currently downloadable files enough for you?

These downloads contain only either free decoders or all the decoders that do not depend on external libraries. Zeranoe would add support for decoders that rely on external libraries, and would be more up-to-date with latest FFmpeg release. Are these worth the change?
