 Specific blurays are now coming with sound tracks with encoded with Dolby
 Atmos support encoded as TrueHD tracks.
 This includes, among others, Transfomers 4, Teenage Mutant Ninja Turtles
 (2014), the one that I personally care about: Roger Waters The Wall
 (2015).

 The current TrueHD bitstreaming and decoding cannot handle these extra
 extensions, and will have no sound on the TrueHD track.

 I have found the appropriate patches that were put into FFmpeg to support
 this, and I have tested with my systems.  Both bitstreaming to a TrueHD
 receiver, and SW decoding of the TrueHD seem to work.
 I have NOT tested with an Atmos capable receiver, but a Kodi thread seems
 to indicate that it should work [''once you ignore the trolls'']

 This problem should not be experienced in master, as the lastest FFmpeg
 resync should have caught this. I have not tested master at all.

 I have the fixes merged into my git tree:
