Part Number: AM62A7

SDK Ver: 10_00_00

I modify tests/app_tiovx_linux_decode_display_test.c and try to capture and display my sensor video. The block diagram is as follows.

The main function is as follows

There is no error when I delete the VISS node.I wonder how to solve this porblem.

The two links above both indicate the same error, and I have also verified that the URL is correct.

Hello,

It's probably related to the VISS node's configuration, but I am unsure what it is specifically - the error message does not tell me enough to estimate why graph-verification failed

You have correctly called the tiovx_viss_init_cfg function -- internally, this sets many default values. I would recommend checking to ensure anything your sensor might need is appropriately overwritten.

https://github.com/TexasInstruments/edgeai-tiovx-apps/blob/be30c7ac2fa65df43aec2c10df3d7c9a98d414e8/modules/src/tiovx_viss_module.c#L225

Please also try running with the logging executable, /opt/vx_app_arm_remote_log.out running in the background. This may show a few additional error messages.

I'd also recommend defining TIOVX_APPS_DEBUG -- this should also add more verbosity
