Design doc/Spec

https://wicg.github.io/mediasession/#dom-mediasessionaction-skipad

Summary

Show a “Skip Ad” button in Picture-in-Picture window that websites can be notified when user interact with.

Motivation

Video advertisement model usually consist of pre-roll ads. Content providers often provide the ability to skip the ad after a few seconds. The Picture-in-Picture window being not interactive, users watching a video in Picture-in-Picture can’t do this today. This feature will allow websites to offer this experience also in the Picture-in-Picture window. This is one of the most common feature requests around Picture-in-Picture.

Risks

Interoperability and Compatibility

Safari has shipped a vendor-prefixed API for Picture-in-Picture and we’re working with them on the integration of the Media Session in Picture-in-Picture.

Edge: Public support

Firefox: No signals

Safari: Public support

Web / Framework developers: Positive

Activation

Web developers will be able to simply set/unset a media session action handler for “Skip Ad” to control the visibility of the button in the Picture-in-Picture window.
Developer documentation will cover this feature as we did before at https://developers.google.com/web/updates/2017/02/media-session.

Goals for experimentation

• Gather feedback about the shape of the API

• Validate that the API provides sufficient functionality for content providers using it to deliver user value. This will be measured by:

• content providers that join the origin trial and choose to share their feedback

• watch time that occurs in Picture in Picture mode

Experimental timeline

• Starts around M73 Beta release, 2019-02-07

• Expires when M74 Stable is cut, around 2019-04-16

Any risks when the experiment finishes?

No significant risks - content providers will feature detect and fall back to their current behavior when we disable the origin trial.

Ongoing technical constraints

None

Will this feature be supported on all six Blink platforms (Windows, Mac, Linux, Chrome OS, Android, and Android WebView)?

The feature will be supported on all platforms that currently support the Picture-in-Picture API.

After more thoughts, we'd like to extend the original trial to expire when M75 Stable is cut, instead of M74 Stable cut.

Note that the origin trial didn't start yet.

Still LGTM

Hi team, 

This feature was initially proposed and implemented 4 years ago but remained disabled due to a lack of practical use cases. Given our team's (chromeOS UI team) plan to use this SkipAd action in our upcoming project, we are now resending this intent email for LGTMs. Please let me know if you have any questions :]

Anticipated spec changes

Open questions about a feature may be a source of future web compat or interop issues. Please list open issues (e.g. links to known github issues in the project for the feature specification) whose resolution may introduce web compat/interop risk (e.g., changing to naming or structure of the API in a non-backward-compatible way).

Unfortunately it doesn't show up in the API Owner UI/ToDo list and I can't directly see how to make it appear. jrobbins, is there anything strange with this one? It is very old so it might be different from anything done the last couple of years.

Are you looking to ship this feature or just experiment? If you're looking to ship please send a new email with a corrected subject and contents, and request API owners review on chromestatus.com.

[Jiaming Cheng]

Hi Chris,

We are looking to ship this feature to Stable. We have reused an existing chromestatus (https://chromestatus.com/feature/4749278882824192?gate=4775000754618368) and updated almost every section, including filling all the "Prepare to Ship" section. This email was automatically generated by the "API Owners Review" step in that section after each individual section was approved. I have quoted the previous email thread in this email for additional context. 

If you have any further questions or concerns, please let us know.

Thanks,

Jiaming

Ok. Please then start a new thread (or reply with a change of subject) to "Intent to ship: Skip Ad in Picture-in-Picture window"

Hey folks,

A few questions from today's API OWNERS:

• Are you investigating a generic action button type, the way we've added one for Notifications?
• If you have investigated that, would this feature be better as a custom user/developer action?
• Have you asked the TAG about consistency w/ Notification Actions for this design? and, most importantly...
• Has there been developer feedback that supports this, either from OT or from community feedback more generally?

Best,

Alex

Hey Alex,

Thanks for your feedback! I have talked with the previous owner (fbeaufort@) of this feature. Please see our answers below inline.

• Are you investigating a generic action button type, the way we've added one for Notifications?
• If you have investigated that, would this feature be better as a custom user/developer action?

The skipAd media session action is not related to Notifications at all. It is a common media action like play, pause, next, previous, skip, etc.  

See historical PR that was approved by Media Session folks: https://github.com/w3c/mediasession/pull/203#issuecomment-432529816

• Have you asked the TAG about consistency w/ Notification Actions for this design? and, most importantly...

The TAG folks have not started talking about this yet at https://github.com/w3ctag/design-reviews/issues/957

• Has there been developer feedback that supports this, either from OT or from community feedback more generally?

Our team (ChromeOS) and the Youtube team are recently planning to integrate this feature in our upcoming project, so that's why we are now proposing to enable it.

Let me know if you have any other questions :]

Best,
Jiaming

Hi Jiaming,

This feature has previously come across my radar as it appears in MDN to be implemented by both Firefox and Safari already:

https://developer.mozilla.org/en-US/docs/Web/API/MediaSession/setActionHandler#browser_compatibility

Is this accurate, is it in fact already implemented in Firefox and Safari?

Best regards,

Philip

From what I can see in https://bugs.webkit.org/show_bug.cgi?id=217797, WebKit implements SkipAd.

Firefox also implements it according to https://bugzilla.mozilla.org/show_bug.cgi?id=1582569

[Jiaming Cheng]

Thanks François for the info! 

Hi Philip, please let us know if you have any other questions or concerns :]

In that case we shouldn't have filed positions and a TAG review..
