Deepstream pipeline

i have the below function code ,

    uridecodebin_c = "uridecodebin_%u" %index
    print("Creating uridecodebin \n ")
    uridecodebin = Gst.ElementFactory.make("uridecodebin", uridecodebin_c)

    splitmuxsink_c = "splitmuxsink_%u" %index
    print("Creating splitmuxsink \n ")
    splitmuxsink = Gst.ElementFactory.make("splitmuxsink", splitmuxsink_c)

    
    # splitmuxsink = Gst.ElementFactory.make('splitmuxsink')
    # pipeline.add(uridecodebin)
    pipeline.add(splitmuxsink)

    #splitmux change
    uridecodebin.set_property('uri', input_url)

    splitmuxsink.set_property('muxer', Gst.ElementFactory.make('matroskamux'))
    splitmuxsink.set_property('location', output_dir + '/' + 'segment_%09d.mkv')
    # splitmuxsink.set_property('max-size-time', 10000000000) #10s segments
    splitmuxsink.set_property('max-size-time', 10000000000) #10s segments


Gst.Bin.add(nbin, queue, nvvidconv_pre, nvosd, nvvidconv, caps, encoder, tee, uridecodebin,  splitmuxsink, encoder0, rtppay, sink)
    #link

    queue.link(nvvidconv_pre)
    nvvidconv_pre.link(nvosd)
    nvosd.link(nvvidconv)
    nvvidconv.link(caps)
    caps.link(encoder)

   

   

    caps.link(tee)
    tee.link(encoder0)
    encoder0.link(uridecodebin)

    #ghostpad
    pad = queue.get_static_pad("sink")

    ghost_pad = Gst.GhostPad.new("sink", pad)

    nbin.add_pad(ghost_pad)

    return nbin

i get the below error

i am able to run removing “uridecodebin”, “splitmuxsink” from bin as below

but i am not able to see the saved video which is done through tee link

Do you see the issue with your code or NV released sample?
