Support for blocking videos on YouTube from individual creators

[pjmattingly]

Description

When searching on Google, Youtube video results are sometimes displayed. Youtube will follow common rules associated with URL structure to indicate content is associated with a creator. For example, if a creator were Anthropic, then the URL to its Youtube channel is: https://www.youtube.com/@anthropic-ai/videos. Then the URL for its Videos section is https://www.youtube.com/@anthropic-ai/videos. Other sections in its channel follow a similar pattern.

However, individual videos published by a channel (e.g. Anthropic) do not commonly follow this pattern; For example the video Building Anthropic | A conversation with our co-founders has a URL of https://www.youtube.com/watch?v=om2lIWXLLN4, which does not indicate that it is associated with the Anthropic channel via its URL. Thus, it becomes difficult to filter out videos from specific creators with uBlacklist. It would be very helpful to filter out specific creators on Youtube from search results.

A possible way to achieve this filtering is by parsing the HTML of the video page. References to the channel associated with the video appear in several places. For example:

Thank you for your consideration.

This kind of issue is intended to be addressed by users with SERPINFO. For example, for search results like this:

You can paste the following SERPINFO into "My SERPINFO" (Options page > SERPINFO > My SERPINFO) to extract the "channel" property. The selector may need adjustment:

name: Google (Custom)
pages:
  - name: All
    matches:
      - https://www.google.com/search?*
    results:
      - name: Videos
        root: .sHEJob
        url: a[href^="http"]
        props:
          title: .OSrXXb
          channel: .Sg4azc  # e.g. "YouTube · Anthropic"

This enables blocking by "channel":

Currently, the dialog doesn't show channel values which makes it inconvenient, so I think this needs improvement.
