Hi,
Display init failed on DriveOs 7.2.5 for nvsipl_camera application.

Note:

If Run without ‘-d’ option, the camera pipeline is working. But we would like to stream the camera’s on display.

same camera works on DriveOs 7.0.3

Kindly share your feedback on this.

Dear @kabilarasan.karunanithi ,
It is known issue with DOS 7.2.5.
Please check Nvsipl_camera Display Initialization Fails (wfdCreateDevice failed)

HI SivaRamaKrishna,

Thanks for the update.

We are looking to stream the camera feed on the display using DriveOS 7.2.5. Are you planning to provide a patch for this issue? If so, could you please let us know the expected timeline for the fix?

In the meantime, are there any alternative solutions available to stream the camera feed on the display?

I need to check with team if any patch can be released for this issue.
We have DW camera sample which can be used to get live camera display(Camera Sample — NVIDIA DriveOS 7.2.5 Linux SDK Early Access Developer Guide). I can provide patch lib for DW camera application if it unblocks you

Hi Siva,
Could you please clarify how the nvsipl_sample application differs from nvsipl_camera?

Also, are any modifications required in nvsipl_sample to support camera drivers other than the default ones? We are using our own custom camera, so we would like to understand what changes, if any, are needed to integrate and stream from our camera.

Thanks in advance for your guidance.
