  1. the difference is only source part. you can use this FAQ to dump the two pipelines. you can use gst-launch command-line to simulate the application. please refer to this pipeline.
gst-launch-1.0 rtspsrc latency=100 location=rtsp://admin:aIlab1234@192.168.1.101/h264/ch1/main/av_stream ! rtph264depay ! queue ! nvv4l2decoder !  mux.sink_0 nvstreammux name=mux batch-size=1 width=1280 height=720 ! nvinfer ! fakesink.
  1. please simplify the pipeline to narrow down this issue. for example,
    please check if “rtspsource+fakesink” pipeline still run into the issue.
  2. if “rtspsource+fakesink” pipeline still run into the issue, there is only one NV plugin nvv4l2decoder in rtspsource, to narrow down this issue, please check if using software decoder still run into the same issue. please refer to the following cmd:
gst-launch-1.0 filesrc  location=/opt/nvidia/deepstream/deepstream/samples/streams/sample_720p.h264 ! h264parse ! avdec_h264 ! fakesink
