TDA4VM: How to Maintain the Remaining Camera Streams When One of the 4 Channel Camera Streams is Disconnected

Part Number: TDA4VM

Tool/software:

HI.

I am using the MultiCam app, and I am experiencing an issue where, when one of the four-channel camera streams is disconnected, the remaining camera streams stop as well. I would like to ensure that the remaining camera streams continue running even when one camera is detached. Additionally, I would like to inquire about how to make the stream resume when the detached camera is reconnected.

The SDK I am using is ti-processor-sdk-rtos-j721s2-evm-09_02_00_05.

Thank you.

Hi Yang,

Have you enabled error frame feature? When this feature is enabled and one or more camera is not detected, then OpenVX node will send this error in place of actual frame for these camera and application will continue running..

When camera is reconnected, you might have to reconfigure SERDES and camera to restart and streaming, this is dependent on the SERDES and camera..

Hi,

Please refer to create_error_detection_frame API in vision_apps\modules\src\app_capture_module.c file.
