[Bug 25092] Need a way to inform script that resolution restrictions are applied

https://www.w3.org/Bugs/Public/show_bug.cgi?id=25092

--- Comment #21 from David Dorwin <ddorwin@google.com> ---
The goal is to avoid wasting bandwidth, CPU, battery, etc. when the client is
unable to display the full resolution of the stream it is being provided. In
this specific case, this is due to policy restrictions.

Maybe there is a more general performance/bandwidth optimization issue that
should be solved in a general (non-EME-specific) way. For example, the
HTMLMediaElement or MediaSource object could have a way to optionally provide
guidance on max (and min) resolution during playback.

Such a feature might be used where high resolutions may not make sense, such as
on certain devices, while on a cell network, or while on battery (especially
when doing software decoding and/or the battery is low). Applications can
detect or imply some of these conditions (i.e. screen size, ISP) but not all of
them.
