How can Emby detect end credits from embedded MKV chapters like it detects intro/episode markers?

[AngelSing 50]

Hi,

I’m trying to understand how Emby uses embedded MKV chapters to show the Skip Intro button and whether there is a similar way to trigger the end credits / next episode button from MKV chapter names.

I have an anime episode with embedded MKV chapters created/visible in MKVToolNix. The original chapter structure is:

Prologue       00:00:00
Opening        00:01:02
Episode        00:02:31
Credits Start  00:22:14
Credits End    00:23:43

 

When I import this episode into Emby and refresh metadata, Emby correctly shows the Skip Intro button at the Opening chapter time. When I click the button, it jumps to the Episode chapter time.

 

 

 

 

 

 

 

 

 

 

 

In the Emby chapters tab, I can also see the normal MKV chapters: Prologue, Opening, Episode, Credits Start, and Credits End.

 

 

 

 

 

 

 

 

When I check the same episode in the Chapter API plugin, I can see that Emby/Chapter API has created or detected special intro markers:

Iniciar intro    Type: IntroStart   00:01:01.691
Finalizar intro  Type: IntroEnd     00:02:31.243

The normal MKV chapters still appear as type Chapter.

 

 

 

 

 

 

 

This confirms that Emby is somehow able to use the embedded MKV chapter structure to create or detect the intro skip markers. What I cannot get working is the end credits button.

I tried renaming the final chapters in the MKV in several ways:

Credits Start
CreditsStart
Credits End
End

But Emby still keeps them as normal Chapter entries and does not create a CreditsStart / StartCredit marker. The end credits / next episode button does not appear at 00:22:14, which is where the credits actually start.

In Chapter API, I can see that CreditsStart is a valid type in the dropdown.

My question is:

Is there a specific MKV chapter name, format, marker type, or metadata structure that Emby recognizes to automatically create a real CreditsStart / StartCredit marker from embedded MKV chapters?

What I want is this:

Embedded MKV chapter:
Credits Start  00:22:14

to be recognized automatically by Emby as:

CreditsStart / StartCredit marker at 00:22:14

without manually editing every episode one by one in Chapter API.

I know Chapter API can add CreditsStart manually, but I have many episodes and I don’t want to manually edit each episode. I’m looking for a way to make Emby recognize the credits start from the MKV chapters during metadata refresh or chapter scan.

Is this currently possible?

If not, is there any server setting, naming convention, scheduled task, plugin, or supported workflow that can automatically convert embedded MKV chapters like Credits Start into real Emby CreditsStart markers?

Thanks.

I'm working on a feature to have EmbyCredit read the embedded timestamps and import them to Emby so they will work.
That should do pretty much what you are asking for, if i understand your question correctly.

I can't promise when it will be done as i'm taking a vacation from most computer stuff here in the summer but, the code is nearly there.

No, it doesn't. That's not how intro detection works.

It scans through the audio of each episode, and looks for a short section that is identical on every episode. This gets marked as the intro. MKV chapter markers are irrelevant to the process; it will work regardless of what the chapter is named or even if there is no chapter marker at all.

This plugin claims to do the same with end credits, though I've never used it:
