I am encountering an issue with the J721EXCPXEVM module.
After changing the NUM_CAPT_CHANNELS constant from 4 to 3 in app_srv_camera, a segmentation fault occurs in the app_run_graph function.
This issue arises when I attempt to execute the graph, and it prevents the application from running as expected.
Could you please provide guidance on how to resolve this problem?

Hi,

May I know the need for this? The SRV application would require 4 cameras to the GPU to stitch and get a surround view output

Thank you for your response.
I also reviewed the Vision Apps User Guide, and it appears that the TIVX Kernels for SRV are intended to use four cameras.
Just to confirm, is my understanding correct that the number of cameras in the TI SRV application is fixed at four and cannot be changed?

Hi.

The SRV application has always been tested with 4 cameras.

So the change to make it support 3 cameras would require more changes of the GPU as well as the application.
