TURN relay in python - nice transmitter

[Skorpeo Skorpeo]

Hello,

Thank you for the quick response!  I spent more time this morning and got a
little further and I had also tried that but it didn't work:/

When I do stream.set_transmitter_ht('nice', {'relay-info':
[relay_structure]}) I get error:

gi.repository.GLib.Error: fs-error: Invalid type of argument relay-info for
transmitter nice (100)

I confirm that this is what I am passing in:
{'relay-info': [<Gst.Structure object at 0x111fb5b80 (GstStructure at
0x7f9d58741bd0)>]}

I was able to get the function to accept the following:

{'relay-info': GLib.PtrArray()}
{'relay-info': GObject.Value(GLib.PtrArray)}

both of which are meaningless because I haven't figured out a way of
putting values in there.

{'relay-info': relay_structure} also doesn't work

I also tried various things like:

value = GObject.Value(GLib.PtrArray)
value.set_value([relay_structure]) #also doesn't work

value = GObject.Value(GLib.PtrArray)
value.set_instance([relay_structure]) #also doesn't work

I also tried other things none of which got me to the promised land.

It seems I have to somehow instantiate a GLib.PtrArray in python but there
appears to be no facility for that and the function doesn't seem to accept
a python list as equivalent?

Your input is greatly appreciated
Many thanks
