Description

I can't find anywhere to add captions to the Mux Player i'm using in React, I have a .vtt file hosted externally but I cannot find anywhere in the docs to load a .vtt file into Mux Player to show the captions.

Reduced test case

No response

Steps to reproduce

Use Mux Player React with an external .vtt file, but there are no docs that show how to successfully load external captions into Mux Player React

Current Behavior

At this present moment after searching through everything, Mux Player doesn't load .vtt files externally or cannot find any documentations on this which means that the current behavior is the same.

Expected Behavior

Mux Player should be able to show captions externally whether .vtt, srt etc from an external source from a CI, CMS, S3 etc.

Errors

No response

What version of the package are you using?

1.14.2

@pateljoel with Mux-hosted videos the captions file that you have should be sent to Mux according to this guide

When you do this, Mux will process the file and deliver the captions with the HLS video.

Does that help?

[pateljoel]

@dylanjha No I don't believe this helps, my .vtt file and my MP4 videos are external and use a different workflow.

Would it be possible to add the ability for vtt / srt files to be read externally into the Mux Player?

@pateljoel ahh I see. Is this a Mux MP4, or an MP4 hosted somewhere else?

The issue is that Mux Player is meant for playing videos that are hosted by Mux over HLS. If you're using an .mp4 video that might technically work, but it's not a use case that we officially test or make sure we have support for.

For creating players for non-Mux content you can build out the same kind of custom player with Media Chrome (this is how we build Mux Player), with that you'd be able to use the <video> element with children <track> elements.

We may have better support for non-Mux hosted videos in the future, but right now Mux Player is focused on Mux-hosted HLS video delivery.
