I'm currently not sure if the current handling not better and we need to update the documentation. The Idea was that you can add ffmpeg sensors/camera and it will test that on startup, that makes the startup slower but for "normal" users it make the config save. If the user is sure that he doesn't need this, he can disable it on component global config with:

ffmpeg:
  run_test: false

Now, both work and not. If you disable it global, the platform settings don't work. That makes it a bit weird. Why are the old settings not working for you?

My specific use case is that I have multiple ffmpeg-based entities, where some inputs are always available and others which turn on/off. The ones that can turn on/off are sometimes not providing feeds when HA is started and it fails to create the entities. On the other hand, I'd like it to validate the inputs which I expect to always be available.

Perhaps the docs (in the components) could reflect that a global override can be set in the ffmpeg platform, but otherwise it will obey the per-component configs?

I've taken your suggestion and gone all-in on configuring tests on the individual components and removed the global run_test config at the platform level. This gives more control and I think is generally easier to understand. Updated docs to reflect this in the linked doc PR.

@pvizeli can you comment on the latest change? I’ll need to fix the tests but want to confirm the new direction is agreeable first.

Closing in favor of #18131.
