Gst-launch-1.0 don't work on jetson nano in Terminal

Hi guys,
I installed the gstreamer libs and dependencies according to Nvidia Gstream Documet, but when I use decoding example like this, I get error. why this error happed?

gst-launch-1.0 filesrc location=<filename.mp4> ! qtdemux name=demux
demux.video_0 ! queue ! h264parse ! omxh264dec ! nveglglessink -e


jnano@jnano-desktop:~$ gst-launch-1.0 filesrc location=1.mp4 ! qtdemux name=demux demux.video_0 ! queue ! h265parse ! omxh265dec ! nvoverlaysink -e

but when I use such way I get correct results:

gst_str = ('rtspsrc location={rtsp} latency=300 ! '
                   'rtph264depay ! h264parse ! omxh264dec ! '

                   'video/x-raw(memory:NVMM), '
                   'format=(string)BGRx ! videoconvert ! '
                   'appsink ')

Hi,
It seems to be version mismatch in the packages. Please install Jetpack4.3 through SDKmanager and try again.
