How do I want to add rtsp 2 sources?

Gst.init()

main_loop = GLib.MainLoop()
thread = Thread(target=main_loop.run)
thread.start()

pipeline = Gst.parse_launch("rtspsrc protocols=tcp  location=rtsp://admin:XXXX@10.117.129.XX ! rtph264depay ! h264parse ! nvv4l2decoder ! m.sink_0 nvstreammux name=m width=1920 height=1080  batch-size=1 live-source=1 batched-push-timeout= 40000 ! nvinfer config-file-path= dsnvanalytics_pgie_config.txt ! nvvideoconvert  ! nvdsosd ! nvegltransform ! nveglglessink")
pipeline.set_state(Gst.State.PLAYING)

try:
    while True:
        sleep(0.1)
except KeyboardInterrupt:
    pass

pipeline.set_state(Gst.State.NULL)
main_loop.quit()

Here have multiple source pipeline sample:

Thank you very much

Can the results be shown separately?
It is now merged into a single window.

How do I assign name(src) to all 3 sources?

for


nvanalytics = pipeline.get_by_name('nvanalytics')

nvanalytics_src_pad=nvanalytics.get_static_pad("src")
if not nvanalytics_src_pad:
    sys.stderr.write(" Unable to get src pad \n")
else:
    nvanalytics_src_pad.add_probe(Gst.PadProbeType.BUFFER, nvanalytics_src_pad_buffer_probe, 0)

nvstreamdemux can separate video source.

How do I assign a name (src) to all 3 sources as one?

for get_static_pad(“src”)


nvanalytics = pipeline.get_by_name('nvanalytics')

nvanalytics_src_pad=nvanalytics.get_static_pad("src")
if not nvanalytics_src_pad:
    sys.stderr.write(" Unable to get src pad \n")
else:
    nvanalytics_src_pad.add_probe(Gst.PadProbeType.BUFFER, nvanalytics_src_pad_buffer_probe, 0)

Suppose need assign different name.
