Describe the issue

Why aren't the changes done with the Control API reflected in the mediamtx.yml file? The changes are there when doing a new GET on the path {name} of the Control API again, however.

I cannot find any documentation on this. Is this by design? How can I retain changes done through the Control API?

Describe how to replicate the issue

1. POST v3/config/paths/replace/{name} (change e.g. record: true/false in body)
2. GET /v3/config/paths/get/{name}
3. Check the mediamtx.yml file. The change is not seen.

Did you attach the server logs?
