Does anyone know whether the (any?) media framework provides container
support or does a related codec handle both the container AND audio/video
streams? I ask because I am worried that having tables on the Media Support
page with entries like:

File format:  MP4 [MP4V/AAC]
Video plays?: YES

... is tending toward simplification, particularly in relation to container
formats. Unless the audio/video stream encoding in a particular
AVI/MPEG/MP4/MKV/etc is known it is difficult to tell if a container format
is going to play or not. Some container formats support quite a few
different stream encodings (one per stream per file).

If the media framework version (e.g., DirectShow included with XP/Vista/7/8)
also affects this, then the picture becomes very complicated very quickly
(with Apple less so b/c they just seem to drop support for old stuff ;-).
Dropping old gstreamer versions is also proving difficult due to a desire to
support a wide variety of GNU/Linux versions:


Presumably this affects what containers and stream encodings are supported?
Happy to hear what others have to say and whether or not I have gone barking

Best wishes, Owen.
