MP4 doesn't support these codecs. (these are in ObjectTypeIndcation list at
mp4ra, but the encapsulation is NOT defined.)
But ISO Base Media (14496-12) does.
Encapsulation of DTS in ISO Base Media is defined and the specification is
opened.
See
http://www.dts.com/~/media/4f6ee2750c81414ab0e0ea95a66992d8/9302J81100F_DTS_ISO_Spec.pdf
Encapsulation of TrueHD in ISO Base Media is defined and the specification
is closed.
PS:
MP4 and M4V are different things.
M4V is Apple-ish MP4 container format which doesn't require Object
Descriptor and BIFS for presentation.
