Add playback restriction example to JWT documentation

[apettenati]

Yes, thank you! I have this working, I just thought I'd recommend adding an example as well.

We recently refreshed the guide for doing signed playback URLs (w/ optional playback restrictions): https://docs.mux.com/guides/secure-video-playback

Closing because this is not a specific issue related to the node SDK

Hi @apettenati, thanks for bringing this up! I hope you figured it out, and we can definitely add more documentation.

As of right now we have one example here with the node SDK if you click the "node" tab

Short answer is you pass in playback_restriction_id: in with the extra params

const { JWT } = require('@mux/mux-node');

JWT.sign(playbackId, {
  params: { playback_restriction_id: YOUR_PLAYBACK_RESTRICTION_ID },
})

let me know if that helps!

how do you create the playback restriction?
when do you create the signed playback id?
how do you insert it to you mux-player?
how do you know the signed playback id is expired and you need to create a new one?
this is so confusing

[rubenheymans]

ok so I can create the playback restriction using postman (is there a ui option coming?)

I create the signed playback id everytime I load the video asset but this makes loading the asset slower

Insert it into mux-player like this:
[attr.playback-id]="file.playbackId"
[attr.playback-token]="signedUrls.playback"
[attr.thumbnail-token]="signedUrls.thumbnail"
[attr.storyboard-token]="signedUrls.storyboard"

How do you know the signed playback id is expired and you need to create a new one?
Can't find any info about this?

@rubenheymans you'll want to set the expiration to a timeframe longer than the length of the video, with some buffer because a user might pause and come back later, scrub, etc.

If the token is expired the player will throw a 403 error and you can catch that, make an API request to get refreshed tokens.
