Hi,
I am trying to get the preview from the sensor in SD660. The sensor outputs Bayer format. I could see from the logs there is a buffer overflow. I get the distorted frames at the beggining and the Snapdragon camera application closes with Media server crash.(logs-1)
When i open the application again, it shows blank screen (logs-2)
Could someone suggest me how to overcome the buffer overflow.
I have enabled CSID and ispif logs.
logs-1:with distorted preview
