I compiled and want to share with you my VideoLAN Media Player Special Edition:
This version include the amr_nb and amr_wb audio codecs that you don't find in the Official VideoLAN Media Player because this codecs have a non-free license.
I compile the contrib, especially ffmepeg with this support for Windows using Mingw and MacOSX using Xcode.
With this packages you can encode, decode videos and make an Streaming Server for mobile devices and 3G VideoCalls.
My last version of VLC 1.0 branch will be 1.0.4-stable.
Note: VideoLAN has announced the VLC 1.1 Branch in your git. They change the git tree and the contrib package, however they don't include the amr or openamr support. I will try to upgrade my own contrib package to this version and pubish here.
The relase can downloaded here: VLC 1.1.3 with amr_nb
