TDA4VM: File based input multicam

Tool/software:

I am working with the app_multi_cam application from the Processor SDK RTOS 11.00 on the J721E EVM.

I have applied the multi_cam_file_input.patchand copied the multi_cam_file folder from multi_cam_file_test_data.zip to the following location on the EVM:

/opt/vision_apps/test_data/multi_cam_file/ 

I have a few clarifications regarding the configuration:

1. Should I enable test_mode = 1  inside the config file, or should it be passed as a command-line   argument?
   ./vx_app_multi_cam.out --cfg app_multi_cam_config.cfg   --test
2. Do I need to mention the input file path   (/opt/vision_apps/test_data/multi_cam_file/)   explicitly in the config file, or is it hardcoded in program?
3. Below is the config file I’m using. Can you please confirm   if it’s correct for running file-based input?
