Unable to switch between streams using input-selector

[Eg Gloor]

Hi all,

I'm trying to switch between two streams and publish it to a RTMP server
using input-selector as follows:

from gi.repository import Gst, GObject
import time

GObject.threads_init()
Gst.init(None)

pipelinelaunch = Gst.parse_launch("""input-selector name=i
            rtspsrc location=rtsp://192.168.100.60/stream1 ! i.
            rtspsrc location=rtsp://192.168.100.61/stream1 ! i.
            i. ! rtph264depay ! h264parse ! flvmux name=mux streamable=true
! rtmpsink sync=false async=false location='rtmp://192.168.100.55/app""")


selector = pipelinelaunch.get_by_name('i')
new_pad = selector.get_static_pad('sink_1')
selector.set_property('active_pad', new_pad)
print(new_pad) # prints None

time.sleep(30)

new_pad is None and the RTMP endpoint shows no stream. Does anyone know
what might be wrong?

Thank you
