	"name": "test",

}

Additional Information

Tested with Homebridge on macOS Big Sur.

For some reason the stream does not work with "encoderOptions": "-preset ultrafast -tune zerolatency", everything except the stream works with this default encoder options even the debug output looks the same just the stream never starts.
