I open this issue to exchange invidious experience / not to say I have zero experience :-)

In the SearXNG default setup we have ..

• My experience is, that a timeout of 5 sec is not need, I got fast response >1sec on my instance.
• Do you recommend different base_url .. is your recommendation related to the continent where the instance is hosted or to the location where the majority of your users are from?

Do you redirect (replace hostname / further see) youtube links to invidious?

Do you miss any feature in our invidious engine or do you have suggestion for improvements?

Here are my /etc/searxng/settings.yml settings (EDIT no longer needed, already added to the sources 10c9b97):

  - name: invidious
    engine: invidious
    # Instances will be selected randomly, see https://api.invidious.io/ for
    # instances that are stable (good uptime) and close to you.
    base_url:
      - https://invidious.snopyta.org
      - https://vid.puffyan.us
      - https://invidious.kavin.rocks
      - https://invidio.xamh.de
      - https://inv.riverside.rocks
    shortcut: iv
    timeout: 3.0
    disabled: true

The instances are used randomly, but all results (incl. youtube) are redirected to an instance in DE where the majority of my users is located:

hostname_replace:

  # youtube --> Invidious

  '(.*\.)?youtube\.com$': 'invidio.xamh.de'
