For tracks that correspond to track elements, the track's identifier is the value of the element's id attribute, if any. For in-band tracks, the track's identifier is specified by the media resource. If the media resource is in a format that supports the Media Fragments URI fragment identifier syntax, the identifier returned for a particular track must be the same identifier that would enable the track if used as the name of a track in the track dimension of such a fragment identifier. AudioTrack and VideoTrack: http://www.w3.org/TR/html5/embedded-content-0.html#dom-audiotrack-id > The AudioTrack.id and VideoTrack.id attributes must return the identifier of the track, if it has one, or the empty string otherwise. If the media resource is in a format that supports the Media Fragments URI fragment identifier syntax, the identifier returned for a particular track must be the same identifier that would enable the track if used as the name of a track in the track dimension of such a fragment identifier. The only example given is that for Ogg Skeleton, the "id" is the name: https://wiki.xiph.org/SkeletonHeaders#Name I'm planning to implement this as: * Matroska / WebM: TrackUID * MPEG-TS: PID * Ogg (without Skeleton): Stream serial number Unfortunately this needs some work on the GStreamer side to make that information available: https://bugzilla.gnome.org/show_bug.cgi?id=711522 2012680 1 pnormand 2024-02-12 06:11:38 -0800 Pull request: https://github.com/WebKit/WebKit/pull/24248 2013468 2 ews-feeder 2024-02-14 03:03:58 -0800 Committed 274623@main (cb24c51631e8): <https://commits.webkit.org/274623@main> Reviewed commits have been landed.
