Please provide complete information as applicable to your setup.

• Hardware Platform (Jetson Xavier AGX)
**• DeepStream Version 4.0.1
**• JetPack Version 4.2.3

**• I am getting low fps =2 while using nvv4l2h264enc with udpsink, The same pipeline while using x264enc with udpsink is giving 30 fps. Can anyone help me in finding out the problem with using nvv4l2h264enc
**• pipeline with nvv4l2h264enc:

**• pipeline with nvv4l2h264enc with fakesink also gives 30 fps

Hi,
Please set the properties in nvv4l2h264enc and try again:

  maxperf-enable      : Enable or Disable Max Performance mode
                        flags: readable, writable, changeable only in NULL or READY state
                        Boolean. Default: false

We suggest set maxperf-enable=1.

  idrinterval         : Encoding IDR Frame occurance frequency
                        flags: readable, writable, changeable only in NULL or READY state
                        Unsigned Integer. Range: 0 - 4294967295 Default: 256

We suggest set idrinterval=30.

And not sure if the linkage rtph264pay ! fpsdisplaysink is valid. Since we expect output of rtph264pay is packet-based, not frame-based. Not sure if it reports correct frame rate in this linkage, but it looks like you have seen correct result with x264enc.

Thank you DaneLLL , I have set mtu property to 65000 in rtph264pay plugin. It gives me 30fps.
