Hi,

```
   I am using a triple IMX 274 suite, which claims to support 1280x540 @ 240 FPS on Jetson TX2, 28.2 L4T.

   But I have confirmed the maximized fps can only reach 80 fps. I have communicated with support enginneer from Leopard Imaging.

   They suggest me to report the bug here and ask for NVIDIA support.

   Following is the command line which I used and video file properties.

   gst-launch-1.0 -e nvcamerasrc fpsRange=240,240 intent=3 ! 'video/x-raw(memory:NVMM), width=1280, height=540, framerate=240/1, format=NV12' ! omxh264enc ! mp4mux ! filesink location=test.mp4

   Video
     Dimensions : 1280x540
     Codec : H.264 ( Contrained Baseline Profile )
     Framerate : 79 frames per second
     Bitrate : 4146 kbps

  I also tried to remove the encoder, with Ridgerun provided gstshark, it also show 

```

0:00:03.766512319 17186 0x530130 TRACE GST\_TRACER :0:: framerate, pad=(string)nvcamerasrc0\_src, fps=(uint)79;

Well, I am working on L4T R28.2. I have tried the image provided by Andrey1984. It will cause SIGSEGV, maybe it’s for 24.2.

The properties of nvcamerasrc shows it already changed to framerate; [0/1, 2147483647/1].

BTW, I can do 120FPS capture with OV camera of the evaluation board. After updating to IMX274 driver, it seems the fps is now limited to 79 FPS.

I double confirmed with Leopard Imaging, they said via v4l2, 240fps is working from driver perspetive. Here is evidance:

v4l2-ctl --set-fmt-video=width=1280,height=540 --stream-mmap --stream-count=500 -d /dev/video0  
\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\<\< 240.00 fps

hello pin.jiang,

could you please have a try to boost system performance by execute jetson\_clock

```auto
sudo ./jetson_clocks.sh

```

in addition,  
could you launch the IMX274@240-fps sensor mode and dump VI and ISP clock rate via debugfs as below, thanks

```auto
sudo -i
cat /sys/kernel/debug/bpmp/debug/clk/vi/rate
cat /sys/kernel/debug/bpmp/debug/clk/isp/rate

```

I just do what you asked.

when the system is idle ( not running the camera ) :

```
 cat /sys/kernel/debug/bpmp/debug/clk/vi/rate
 409600000

 cat /sys/kernel/debug/bpmp/debug/clk/isp/rate
 768000000

```

when the system is busy ( IMX274 running @ 240FPS ) :

```
 cat /sys/kernel/debug/bpmp/debug/clk/vi/rate
 230400000

 cat /sys/kernel/debug/bpmp/debug/clk/isp/rate
 396800000

```

hello pin.jiang,

it’s weird that clock rate become half during the sensor is running,  
please execute below commands to boost the system performance for testing.  
thanks

```auto
sudo ./jetson_clocks.sh
echo 1 > /sys/kernel/debug/bpmp/debug/clk/vi/mrq_rate_locked
echo 1 > /sys/kernel/debug/bpmp/debug/clk/isp/mrq_rate_locked

But I found the saved MP4 is still 79 FPS only. I will upload the mp4 shortly later.

Hi pin,  
Do you see 240 fps with fpsdisplaysink?

I use the script:

GST\_DEBUG=fpsdisplay:5 gst-launch-1.0 nvcamerasrc queue-size=3 sensor-id=0 fpsRange=“240 240” ! ‘video/x-raw(memory:NVMM), width=1280, height=540, framerate=240/1, format=NV12’ ! fpsdisplaysink video-sink=false sync=false async=false

… DEBUG fpsdisplay fpsdisplaysink.c:376:display\_current\_fps: Updated max-fps to 81.593611  
… DEBUG fpsdisplay fpsdisplaysink.c:376:display\_current\_fps: Updated min-fps to 81.593611

… DEBUG fpsdisplay fpsdisplaysink.c:376:display\_current\_fps: Updated min-fps to 79.182683

So saved the mp4 file, gst\_shark and fpsdisplaysink all indicate the fps is around 80. But I do achieved 120 FPS with the on-board OV camera.

Hi pin, the log shows your sensor can only achieve ~80fps. Are you able to contact Leopard to get further support?

Yes. But Simon Zhu from Leopard Imaging asked me to run below commands on Jetson Tx2:
