Brave-browser: Purchased content from youtube doesn't prompt to install Widevine (Amazon too)

[bbondy]

Description

A user from Twitter reports that purchased content doesn't prompt to install Widevine.

Widevine currently only prompts to install based on URL pattern:

https://github.com/brave/brave-core/blob/a57dc16dba02ea52adcca39a5189533e15168752/common/shield_exceptions.cc#L127
But we don't want to prompt for all of youtube.com for Widevine.

So we'd need a content script or some kind of network filter or other detection mechanism.

If Widevine is already installed, it does play.

Steps to Reproduce

I haven't tried these steps yet, but I think they would be:

1. Go to in a new profile https://www.youtube.com/watch?v=RQn-Pqvnzc8
2. Purchase it

Actual result:

Video doesn't play

Expected result:

It prompts to install Widevine in the URL bar. Clicking the prompt should make the video play.

Reproduces how often:

Always, as long as Widevine is not installed.

Brave version (brave://version info)

Reproducible on current release:

• Does it reproduce on brave-browser dev/beta builds? Yes

Website problems only:

• Does the issue resolve itself when disabling Brave Shields? No
• Is the issue reproducible on the latest version of Chrome? No

There is also an issue on Spotify & Amazon.de where users don't get prompt for Widevine to play prime videos, but works on primevideo.com
