The specification defines "Mappings [...] for [MPEGDASH], [ISOBMFF], [MPEG2TS],
[OGGSKELETON] and [WebM]. " Those standards are partially overlapping. For
instance an MPEG-DASH manifest may be used to describe a streaming session made
of ISOBMFF files or MPEG-2 TS files. Unfortunately, some information in the
DASH Manifest may be redundant (or contradictory) with the information in the
container file, for example the language. The specification should indicate how
to resolve those conflicts. Ideally, the container file information should
prevail, unless it's missing information; so that the playback of a file from a
manifest or directly in the video element produce the same result.
