input-selector pixelation when changing active-pad on RTSP stream

I am trying to switch between 2 RTSP input sources and push it to another
rtsp stream as an output. When performing encoding-decoding things work well
but I found it unnecessary as it was using lots of processing. Hence, I am
trying to just switch between the payloads from the inputs but as soon as
active-pad is changed there is a pixelation in the screen for a second and
then the stream is good.
I'm coding in python and this is my pipeline:
*PIPELINE = """
rtspsrc location=rtsp://10.64.0.5:554/stream0 is-live=true latency=0 !
rtspsrc location=rtsp://10.64.0.5:554/stream1 is-live=true latency=0 !
input-selector name=selector ! rtph265depay ! rtph265pay name=pay0 pt=96
I'm using GstRtspServer as my rtsp server. When playing the stream with
ffplay as soon as I trigger the active-pad change I see this error msg in
red in the console : "Could not find ref with POC 61"
Here is my call to change active pad:
* def on_switch(self):
active_pad = self.selector.get_property("active-pad")
if active_pad.get_name() == "sink_0":
new_pad = self.selector.get_static_pad("sink_1")
new_pad = self.selector.get_static_pad("sink_0")
print("switching from %s to %s" % (active_pad.get_name(),
