Collections: Store reliable total duration

[doc-code-hub]

Introduction

Viewing the total duration of a content on the detail page can be very useful as information, for organizing or predicting the end.

Likewise, I think it could be convenient and useful to be able to view the total duration of a collection (eg to plan a marathon).

Suggested Enancement

Basically I would like the total RunTimeTicks of the collection to be saved, recursively obtained from all the children.

This way clients would be able to show them immediately in user-readable format.

---

I had tried to achieve this purpose client-side ( on jellyfin-web #3552 ), however it remains impossible to have a reliable total duration with all types of content ( e.g. with collection inside collection), moreover the information was deduced by the children, who were retrieved at a later time, introducing a delay.

It has been pointed out to me (by @thornbill), and I agree, that it would be much better if this information were computed and stored server-side.

• It would be much more comfortable
• It would make the information available immediately
• It would allow to always have a total effective duration, regardless of the type of content inside (also solving the problem of collection within collection or series).

In this regard, I am trying to propose an implementation on the related PR and i'm open to suggestions (on the PR please :) )

My Implementation in short

• Add UpdateRunTimeTicksToItems method in BoxSet
• Handle update of RunTimeTicks when adding/removing items from the collection
• Add a Task to update the RunTimeTicks for the collections (to handle eventual file remove and RunTimeTicks update)
