This is useful for toggling a GPIO output configured before launching gst pipeline. We use this to toggle external LEDs on our camera.

Not sure if this is something worth upstreaming or a more general escape hatch would be better.

Did you try the features property ?

aravissrc features="UserOuputValue=1"

Yea I've noticed that but wasn't sure if it actually sets it during runtime as well as it uses

gst_aravis->features = ..

can try!

Sorry, I've missed this requirement. No it currently does not set features while the pipeline is running. But it should be pretty trivial to change that.

And it would be more generic than setting UserOutputValue.
