Identify the source of the change event (automatic, or manual upload) for video/audio components

[altryne]

• [x ] I have searched to see if a similar issue already exists.

Is your feature request related to a problem? Please describe.
Would like to be able to diffrentiate between a user initiated manual upload to a Video and an automatic value update from somewhere else

Describe the solution you'd like
Add a .upload event, that causes the .change event to have metadata for the upload.

Additional context
This is helpful as right now, I have to use 2 separate elements for uploading and for showing a result, I would like that to be 1 element

Thanks for creating the issue @altryne. Just to confirm, when you say

automatic value update from somewhere else

you mean if the Video component is being set as the output of some function, correct?

I think it would be good to extend this functionality to all of our components, actually.

Yeah. The change is fired when the user uploads some media but also when the component data is set via a predict function. There is currently no way to differentiate.

I actually think having a general change event is quite nice because many people don’t care how the data is set, they just want to know when it is but it would be good to have some way to differentiate.

(This issue was created after some discussion in discord which is why I have the additional context)

Completely agree, I think change should work all the time.

But maybe an .upload event could be fired before so that I could save a reference somehow? Not sure if I overstep with implementation suggestions.
