TDA4AL-Q1: How to confirm whether the 4 channels surround view is synchronized through log

Dear TI expert，

         1. How to confirm  4 channels surround view  viss receive four channel image timestamp when 4 channels surround view image sensor output format is raw ?

         2. How to confirm  4 channels surround view  ISP receive four channel image timestamp when 4 channels surround view image sensor output format is yuv ?

         Is there a log that can print the timestamp of the received image from four channels？

         Because the algorithm needs to know if the four channel images are synchronized when receiving them.  Thanks!
