[Bug 24859] Automatic Video and Audio Track Selection Based on User Preferences and Terminal Characteristics

https://www.w3.org/Bugs/Public/show_bug.cgi?id=24859

--- Comment #4 from Jon Piesing (HbbTV) <hbbtvjon@gmail.com> ---
>From what you're saying, I assume you're concerned about audio and video tracks activated based on
1. Preferences given in-band in the media files
2. User preferences set in the browser

Specifically that the language for the first of these (preferences given
in-band in the media files) can be interpreted as excluding the second.

"If the media resource indicates a particular set of audio or video tracks to
enable, then the selected audio tracks must be enabled in the element's
audioTracks object, and, of the selected video tracks, the one that is listed
first in the element's videoTracks object must be selected. All other tracks
must be disabled."

That does not refer to user preferences set in the browser and can be
interpreted as excluding enabling tracks on that basis - "All other tracks must
be disabled".

>So, nothing about user preferences will be normative in the spec.

Clear

> The spec only has to be accurate in how it reacts to audio or video tracks that have been activated/deactivated by the browser.

Yes.

> I can see how you might want to see this expressed more explicitly.

Avoiding a situation where reasonable people interpret this as being excluded
would be a start.
