bug(YouTube): Autoplay fails when Sponsorblock skips to end of video

[0-Kirby-0]

Bug description

When a Sponsorblock segment stretches to the end of a video, and that segment is skipped, Autoplay does not correctly trigger to play the next video.

Applies whether the segment is manually or automatically skipped.
Applies to both playlists and non-playlist autoplay.

Steps to reproduce:

1. Set Sponsorblock settings to allow skipping of relevant segment types, Endcards and Promos being particularly common.
2. Activate Autoplay and/or open a playlist
3. Play a video with a Sponsorblock segment stretching to the end.
   (For testing, large commercial YouTube channels are a good place to look, for abundant and aggressive segmenting, as well as consistent skippable filler)
4. Skip said segment.

Solution

Bodge suggestion:
Add a special case when a segment's end time is identical with the end time of a video, and reduce the segment's end time by a fraction of a second before skipping. This should let the final frame(s) play normally, meaning autoplay should trigger normally.

A proper solution would likely involve manually triggering the next video on that special case, I have no knowledge about this.

There already is a fix that adjusts the segment end time if it runs over the actual video length.

Try repatching and exclude Disable suggested video end screen and exclude Always repeat

If that does not fix it, then repatch with only SponsorBlock and GmsCore Support

Requested Playlist
First video ends with a self-promotion.

Issue applies to any and all videos and playlists fitting the criteria explained above, so I assumed reproduction would be trivial.
Issue has further persisted over multiple different pre-builts, as well as into ReX, so if the bug doesn't materialise on your end, something's afoot.

[LisoUseInAIKyrios]

I cannot reproduce on my end. When using either autoskip or manual skip, the playlist continues to the next video after the skip.

Try using a different YouTube account and/or try incognito mode. Maybe it's an unrelated a/b test that is interfering.

If anyone else can reproduce this and is savy with building locally, they can try adjusting the end segment skip logic here, and try increasing the 250 to a larger value and maybe that will fix it.

Problem persists with alternate account and incognito mode.

Also: The bug only appeared after the watch history changes, and me updating/replacing my Rev client, autoplay worked as intended prior to that.
I hadn't updated Rev in months, so the breaking change doesn't have to have been recent.

I'll give this a couple days and pray that someone else can reproduce, I really don't wanna have to set myself up for app dev over this.

Thank you!

With no repro, I decided I don't care enough to try to patch this myself, the effort would be completely disproportionate since I'm not set up for it and I don't know anything about the Rev and YT codebases or the languages used.

Thank you for your help.
