Trouble on running Sample on egra_multimedia_api and argus\samples on Jetson TX1 Board

After install Jetson TX1 R28.2, I just want to test built-in camera OV5693 On Nvidia TX1 board.

I see some sample on the direction egra_multimedia_api:

  1. tegra_multimedia_api\samples
  2. tegra_multimedia_api\argus\samples

I try to running the sample tegra_multimedia_api\samples\10_camera_recording on Jetson TX1, But get following error message:

Set governor to performance before enabling profiler

Are there any document on following Items?

  1. What is the function feature with tegra_multimedia_api\samples?
    2 What is the function feature with tegra_multimedia_api\argus\samples and how to build and run those sample?

I also try to run a v4l2-ctl test on Jetson TX1
• Enter the command:
v4l2-ctl --set-fmt-video=width=1920,height=1080,pixelformat=RG12 --stream-mmap -set-ctrl=sensor_mode=0 --stream-count=100 -d /dev/video0

ubuntu@tegra-ubuntu:~$ v4l2-ctl --set-fmt-video=width=1920,height=1080,pixelformat=RG12 --stream-mmap -set-ctrl=sensor_mode=0 --stream-count=100 -d /dev/video
it say: Unknown standard ‘et-ctrl=sensor_mode=0’


You have run it successfully. Please check presence of outout.h264

nvidia@tegra-ubuntu:~/tegra_multimedia_api/samples/10_camera_recording$ ls -all output.h264
-rw-rw-r-- 1 nvidia nvidia 505659 Mar 20 06:31 output.h264

And you can play it by running 00_video_decode

nvidia@tegra-ubuntu:~/tegra_multimedia_api/samples/00_video_decode$ export DISPLAY=:0
nvidia@tegra-ubuntu:~/tegra_multimedia_api/samples/00_video_decode$ ./video_decode H264 ../10_camera_recording/output.h264


Thank you for your feedback.
Are there any document on the tegra_multimedia_api\argus\samples?
Just for sample feature and build and test steps.
