In Raspberry Pi board if we want to run camera preview we have to give the below command with time. And we can increase the time as per our requirement so preview will run continuously till the time complete.
"raspistill -t 2000"
I am implementing the camera driver support in Android for Raspberry Pi. Now camera preview is running and it is running only few seconds. Please let me know how to increase the time and how to run continuous preview through MMAL code.
