Fixes #340.

Bikeshed now requires Python 3.9; you are on 3.8.10.
If you're seeing this message in your CI run, you are
likely specifying an old OS; try ubuntu-latest.
If you're seeing this on the command line, see the docs
for instructions:
https://speced.github.io/bikeshed/#installing
Command bikeshed update failed with exit code: 1.

@tidoust, do you know what happened there?

Needed to get Python >=3.9 for Bikeshed. Also used this opportunity to bump the version of the checkout action used. Via #350 (comment)

@tidoust, do you know what happened there?

Job was using an old version of Ubuntu that ships with Python 3.8. Now using ubuntu-latest, see #351.

index.bs

  sequence&lt;ChapterInformationInit> chapterInfo = [];
 };
+
+enum MediaKind {


Can we add a section describing what these mean? "advertisement" is obvious to me, but the rest are not so obvious

I updated the enum and added some description.
Let's discuss this enum.

Does the implementation make use of these values, e.g., in a default action handler? I'm wondering if an enum is needed and we could let the web app set any value it wants, using DOMString.

Also, a web app might want to skip between chapters, so do we need similar on ChapterInformation?

kind could influence UA UI (whether displaying a skip button, for how long, skip button label customisation to Skip intro for instance...). An arbitrary DOMString might add complexity and would disallow feature detection.

do we need similar on ChapterInformation?

Right, this PR adds kind to ChapterInformation as well.

Makes sense, thanks.

This list may be a bit too specific, for example BBC might want to offer a skip to next news item, skip to next song, or whatever.

index.bs

steimelchrome · 2025-01-08T00:01:11Z

index.bs

+      typically happening at the beginning of a TV series episode and summarizing past episodes.
+    </li>
+    <li>
+      the empty string: the default value of media content, it represents any other value of a part of media content.


Seems like empty string will be used to mean both "actual content" and "unknown content". Should there be an explicit value for actual content?

Changed to other for now.

This generally lgtm just added a bikeshed comment on the MediaKind enum

marcoscaceres · 2025-01-14T22:06:37Z

index.bs

+  "opening-credits",
+  "post-credits-scene",
+  "summary",
+  ""


Maybe let's just call this "content" ? or "other".

Changed it to other, note that the default value of the dictionary kind value is also updated.

Discussed today in media WG meeting.
PR seems good with the following changes:

Rename "" to "other" inMediaKind enumeration
Add a note stating that MediaKind enumeration is experimental and can be extended.

I may also add wording about potential default handlers, (seek to next chapter if skipping a chapter or to the end if there is no chapter).

youennf · 2025-01-14T22:34:16Z

@chrisn, would the note and the renaming of "" to "other" cover your concerns? Or do you have a better idea in how to handle the case of "next song", "next news"...?

steimelchrome · 2025-01-21T19:15:58Z

index.bs

    <li>Its <a for=MediaMetadata>title</a> is the empty string.</li>
    <li>Its <a for=MediaMetadata>artist</a> is the empty string.</li>
    <li>Its <a for=MediaMetadata>album</a> is the empty string.</li>
+    <li>Its <a for=MediaMetadata>kind</a> is the empty string.</li>


Should this say the kind is "other"?

steimelchrome · 2025-01-21T19:17:03Z

index.bs

 dictionary ChapterInformationInit {
  DOMString title = "";
  double startTime = 0;
+  MediaKind kind = "";


Same question here about whether it should be "other"

chrisn · 2025-01-21T19:27:36Z

@chrisn, would the note and the renaming of "" to "other" cover your concerns?

@steimelchrome asked about "actual content" vs "unknown content" so I'm not sure I see how renaming "" to "other" addresses that. For us, there may not be a need to, and "" could be enough as a general purpose skip. But (and separately to the WG) we'd be interested to see what kind of UI treatment browsers might be planning for these skip actions.

Pull Request Overview

This PR introduces a generic skip action to replace the advertisement-specific skipad action, and adds a new MediaKind enumeration to categorize media content types. This allows for more flexible skipping behavior based on different types of media content rather than being limited to advertisements only.

Replaces the skipad action with a generic skip action
Adds a new MediaKind enumeration with values for different content types (advertisement, credits, content, etc.)
Integrates MediaKind into both MediaMetadata and ChapterInformation interfaces

Copilot · 2025-08-21T11:37:03Z

index.bs

  attribute DOMString title;
  attribute DOMString artist;
  attribute DOMString album;
+  readonly attribute MediaKind kind;


The 'kind' attribute is marked as readonly in the interface but can be set through MediaMetadataInit. This inconsistency could confuse API consumers about whether the property is mutable after construction.

Copilot · 2025-08-21T11:37:03Z

index.bs

 interface ChapterInformation {
  readonly attribute DOMString title;
  readonly attribute double startTime;
+  readonly attribute MediaKind kind;


Similar to MediaMetadata, the 'kind' attribute is readonly in ChapterInformation but can be set through ChapterInformationInit, creating potential confusion about mutability.
