WICG Media APIs

[marcoscaceres]

The following media-related APIs are in the final stages of being migrated to the newly rechartered W3C Media Working Group - the proposals have been incubating for a few years, and Media WG (co-chaired by Apple and Google), intend to formally standardize... I'm assuming that Apple's involvement means there is a moderate chance some of these APIs will be implemented in WebKit (maybe some have already?). They are all shipping in Chrome I believe. Apart from our loosely formed opinion on Picture-in-Picture (#72), I'm unsure about our plans for others:

• Media Capabilities - intent to migrate. See also Media Capabilities #184.

• Picture-in-Picture - intent to migrate. See also: Picture-in-Picture #72.

• Media Session - intent to migrate See also: Media Session API #28.

• Media Playback Quality - intent to migrate. See also Media Playback Quality #185.

• Autoplay Policy Detection - intent to migrate. See also Autoplay Policy Detection #186.

CC @padenot and @jyavenard, as members of the working group, and @mikeconley re: PiP.

If there are any concerns about them migrating or we believe some need further incubation, it would be a good time to speak up. Similarly, it would be good to express some position for these specs.

The WICG Chairs will be reviewing the intents to migrate, linked to above, over this week with the aim of migrating them by next week.

Picture in Picture: we're following the spec but don't plan to currently implement the API.
Media Capabilities: we implement and ship the spec, and we're currently implementing and intend to ship additions to the spec.
Media Session: we don't implement, but we are considering implementing and shipping in in the short to medium term. In particular, we're currently doing experiments to support this effort at the platform level.
Media Playback Quality: we implement and ship this spec, and intend to continue doing so, were it to change.
Autoplay Policy Detection: we are actively participating to the spec discussion, and plan to implement and ship the outcome of this discussion.

I'll write something to formally express our position.

@padenot, @annevk, in the intent to migrate for media playback quality, @domenic raised a concern about where standardization should happen: Media WG or WHATWG? Might be good to chime in there too.

Closing, as we now have separate issues for each.
