 It seems that packaging a TRUEHD/MLP stream into a mp4 container isn't
 supported by any currently available software - despite the capabilities
 of the MP4 container.

 References:
 http://mp4ra.org/#/codecs - see codec mlpa - (clearly states support for
 Dolby MLP)
 https://developer.dolby.com/globalassets/technology/dolby-
 truehd/dolbytruehdbitstreamswithintheisobasemediafileformat.pdf -
 describes the storage of Dolby® TrueHD (MLP) audio bitstreams in a file
 format compliant with the ISO base media file format
 https://en.wikipedia.org/wiki/Comparison_of_video_container_formats - see
 audio coding formats support - also clearly states support for TRUEHD in
 mp4.
