Looks like didn’t receive any validate data from the sensor.  
Maybe need to probe the signal and sensor power sequency.

when the situation occur ，just stop the v4l2 commad ,and execute the cmd again ，it could get the video data；

For this I would suspect it could be the sensor power on sequency problem or the THS\_Settle timing problem.  
Please confirm the timing by MIPI spec.
