If you want to mux TrueHD into MP4, you need the latest developer version of FFmpeg, because experimental support for that was just recently added. Because it is
experimental, you also need to add "-strict -2". But, there is currently no hardware supporting this, so AppleTV will not be able to play the resulting file. For
AppleTV I recommend converting the audio stream to E-AC3 instead.
