🦟 Bug: Pass custom events to data integration

[endymion1818]

*** EDIT: Sorry this seems to be a bug, my colleague found this line of code that looks like it should update analytics when updated attributes are passed to the element ***

Is there an existing issue for this?

Which Mux Elements/Packages does this apply to? Select all that apply

mux-video

Description

Currently, we are able to pass data to Mux analytics via attributes on the element, for example:

<mux-video
    env-key="some-env-key"
    metadata-video-title="My Video"
>
</mux-video>

This tracks fine in Mux Data dashboard.

However if we later wanted to update the video title (use case is a change to the playing video, or some other metadata associated with relevant user behaviour), I don't think it's possible to update the metadata.

I've tried updating the attribute like this:

const video = parent.shadowRoot.querySelector('mux-video');
video.setAttribute('metadata-video-title', 'New Title')

❌ This doesn't work, the data sent to Mux Data still maintains the old title.

Even though it looks like there is a MutationObserver for those elements:

https://github.com/muxinc/elements/blob/1e6972805459a0bb3a18b5b5a6d0bbf32c900b17/packages/mux-player/src/video-api.ts#L178

Expected Behavior

I would like a custom event I can hook into so that I can update the metadata, something like:

const video = parentElement.shadowRoot.querySelector('mux-video');

video.dispatchEvent(
  new CustomEvent('metadata', 'New Title')
)

Or for updating the attributes to be observed by the internal mux-data integration so that updating the attributes also updates the mux data.

As an aside, I tried to write a custom integration using the HTML <video> element but it doesn't support your extended video element, instead it specifically looks for a <video> element.

Just to emphasise this is a blocker for us. We have a mux data integration for JWPlayer in prod and we need to be able to maintain the same feature set that is provided with that integration.

I really don't want to stick with JWPlayer 😭
