gen2-rtsp-streaming appears to be broken on macOS 13.1 with M1

[artificiel]

hello! trying the gen2-rtsp-streaming does this:

gen2-rtsp-streaming % python3 main.py
Available devices:
[0] 18443010B1A3BD0800 [X_LINK_UNBOOTED]
Setup finished, RTSP stream available under "rtsp://localhost:8554/preview"

all seems good; then when starting a stream in another terminal:

Traceback (most recent call last):
  File "(...)depthai-experiments/gen2-rtsp-streaming/main.py", line 35, in do_create_element
    return Gst.parse_launch(self.launch_string)
gi.repository.GLib.Error: gst_parse_error: no element "appsrc" (1)

note that in addition to the brew gstreamer things I needed a pip install gobject PyGObject, and that the M1 brew adjustment referenced in https://stackoverflow.com/q/64882584 are no longer needed.

FYI output in the ffplay terminal (confirms the server is not working):

Hi @artificiel ,
Looks a bit like version problem. Are versions of all libraries correct (math to the required ones)? Might be an issue because it's on M1 and some lib doesn't support this platform.
Thanks, Erik
