Hi,
In gstreamer frameworks, there is mechanism of doing synchronization according to frame timestamps. when comparing to TX2/Xavier, Jetson Nano is with less GPU power and if nvinfer plugin takes more time in processing frames, it may block and triggers the warning messages:
WARNING from sink_sub_bin_sink1: A lot of buffers are being dropped.
Debug info: gstbasesink.c(2902): gst_base_sink_is_too_late (): /GstPipeline:pipeline/GstBin:processing_bin_0/GstBin:sink_bin/GstBin:sink_sub_bin1/GstEglGlesSink:sink_sub_bin_sink1:
There may be a timestamping problem, or this computer is too slow.

We would suggest disable the mechanism on Jetson Nano. There is a similar post:

‘qos’ is also a mechanism in gstreamer. Please check
