Camera Capture
Camera capture pipelines were tested with a Sony IMX219 CMOS (Raspberry Pi V2.1 camera) image sensor. The Jetson Xavier NX has the following power mode "NV Power Mode: MODE_15W_6CORE" and jetson_clocks binary was executed to set the board in maximum performance mode.
Using nvarguscamerasrc with a Sony IMX219 CMOS image sensor (Raspberry Pi V2.1 camera), the following operation modes are available:
GST_ARGUS: Available Sensor modes : GST_ARGUS: 3264 x 2464 FR = 21,000000 fps Duration = 47619048 ; Analog Gain range min 1,000000, max 10,625000; Exposure Range min 13000, max 683709000; GST_ARGUS: 3264 x 1848 FR = 28,000001 fps Duration = 35714284 ; Analog Gain range min 1,000000, max 10,625000; Exposure Range min 13000, max 683709000; GST_ARGUS: 1920 x 1080 FR = 29,999999 fps Duration = 33333334 ; Analog Gain range min 1,000000, max 10,625000; Exposure Range min 13000, max 683709000; GST_ARGUS: 1280 x 720 FR = 59,999999 fps Duration = 16666667 ; Analog Gain range min 1,000000, max 10,625000; Exposure Range min 13000, max 683709000; GST_ARGUS: 1280 x 720 FR = 120,000005 fps Duration = 8333333 ; Analog Gain range min 1,000000, max 10,625000; Exposure Range min 13000, max 683709000;

Videotestsrc display
The Jetson Xavier NX has the following power mode "NV Power Mode: MODE_15W_6CORE" and jetson_clocks binary was executed to set the board in maximum performance mode.
gst-launch-1.0 videotestsrc is-live=true ! video/x-raw, width=1920, height=1080 ! nvoverlaysink
Note: A videotestsrc pipeline to fakesink is capable to achieve at 1920x1080 resolution a maximum framerate of 97.5fps with a CPU load of 17%
