Reducing one second delay on rtsp h264 stream from IP camera

[chars]

Hello all.

I am using the OpenFrameworks (which is a cpp wrapper)  ofxGStreamer addon
<https://github.com/arturoc/ofxGStreamer>   to receive and display an rtsp
h264 IP security camera stream. I am trying to get it to be as close to realtime as possible. The
IP camera is wired to a router which is wired into my laptop, at a very
short distance, so I can't blame the connection or distance. I can use some
software on my windows machine called iSpy which has a latency/delay of a
matter of a few hundred milliseconds, while my OF app has a delay of 1
second.

The pipeline is:
rtspsrc
location=rtsp://admin:@192.168.8.192:554/live;stream=0;drop-on-latency=true;
latency=0 ! queue2 max-size-buffers=2 ! decodebin ! videoconvert !
videoscale ! appsink name=ofappsink enable-last-sample=0 caps="video/x-raw,
format=GRAY8, width=341, height=251"

Please let me know if there is something obvious I should try, this is my first time using Gstreamer, I am happy I was able to get it down from 3 second latency to 1 second but I've been stuck here for a while
now. I don't care about quality or artifacts, just that it is close to
realtime as possible. I believe that because it is RTSP I as the client make
requests to how it is being streamed so I can't blame how the camera is
sending the stream.

Thanks for reading, and comments or suggestions are greatly appreciated.

Hello again,
The strange thing is that reducing the bitrate or resolution doesnt have an
effect on the latency at all. I tried using gst-launch-1.0 and
gst-inspect-1.0 to get a better insight on how to speed up this pipeline but
to no avail, I just need to work with the actual pipeline in my app because
those can't really simulate it accurately. I am completely new at this, and
have been working at it for weeks (I can go on with what I tried but I don't
want this post to be too long), I can't seem to get a lower
latency/processing speed.
this is my pipeline at the moment

rtspsrc
location=rtsp://admin:@192.168.8.192:554/live0.264;stream=0;user=system;pass=system;
width=192, height=108,framerate=15/1 gop-size=1 bitrate=20
drop-on-latency=true  latency=0 ! queue2 max-size-buffers=0 ! decodebin !
videoscale ! videoconvert ! appsink name=ofappsink enable-last-sample=0
caps="video/x-raw, format=RGB, width=192, height=108"

How can I make it so that reducing resolution will speed up processing? It's
the same if its 1920x1080 or 192x108. Thank you for reading, any insights
are appreciated!

I have found that the camera is streaming multiple streams, one for fast
connection, one for recording and one for phones. I was using the one for
recording, I can change streams by changing the end of the url to live1.264
instead of live0.264.

But this doesnt have effect on the latency! Is it because I am on OSX?

rtspsrc location=rtsp://admin:admin@192.168.8.102:554/live2.264;
drop-on-latency=true latency=0 ! decodebin ! videoconvert ! videoscale !
appsink name=ofappsink enable-last-sample=0 caps="video/x-raw, format=GRAY8,
width=256, height=256"
