OV9281 streaming

Sunim_1 · May 26, 2026, 2:26pm

I am currently working on OV9281 camera sensor and I am able to capture raw img from the sensor, however I am trying to stream camera on nvidia jetson xavier nx som using nvarguscamerasrc but seems like its not streaming. Could you please help me how come I able to stream this camera.
I am using kernel version 5.10 and also is there any camera_override.isp file for the same. If so, kindly share any link if someone has used.

Thanks…

I mean what’t the gstreamer log?

And what’s the daemon log.

journalctl -u nvargus-daemon -f

Sunim_1 · May 28, 2026, 7:12am

I am able to stream using nvarguscamerasrc but stream is slightly a pinkish tone.

OV9281 sensor is monochrome so how do I achieve monochrome gray tone.

Using mode type: gray and pixel_phase= y removes the video nodes. Only bayer with rggb or bggr works. Is that with argus architecture to forcefully mention bayer mode type.

ShaneCCC · May 28, 2026, 7:18am

Add below parameter to /var/nvidia/nvcam/settings/camera_overrides.isp

Need change the file to 664 to apply the isp overrides

Sunim_1 · May 28, 2026, 7:21am

could you please share any source of camera_overrides.isp file on nvidia forums

ShaneCCC · May 28, 2026, 7:27am

Actually it’s text file only you can create it by yourself.

Thanks

One more thing after applying your suggestion for isp tuning pinkish tone gone but still there is too much noise and no clarity in the feed so could you please suggest some more add on parameters for isp tuning using camera_overrides.isp file. It would be a great help for me to move forward.

Thanks in advance..

Noise in low-light conditions
Lack of sharpness and contrast optimization
Inconsistent grayscale reproduction for the monochrome OV9281 sensor
contrast optimization
stable exposure/gain behavior

Could you please help with:

Sorry to tell. We don’t support monochrome sensor tuning.

Sunim_1 · June 1, 2026, 6:39am

mode_type = “grey”;
pixel_phase = “y”;

Is this mode format is supported for monochrome sensor ov9281 I am using or do I need to forcefully use bayer format rg10 ?

ShaneCCC · June 1, 2026, 7:02am

Argus only support Bayer format.

For grey format you can use v4l2 app like v4l2src …
