Hi,

Can you allocate bigger output buffer as shown below?

format.height = (pObj->maxHeight + 32);

status = Utils_memFrameAlloc(&format, frames,
numBufsPerCh);

regards,

Anand

i tryed it .

now the image is good.

but why ? can you tell me ?

Hi,

The sensor may be writing some blanking data.

You can dump a frame and see how much blanking data is written.

Alternatively reduce the hike in the height and check at what point you get the proper image.

Anand

I set "vipInstConfig->vipConfig.clipBlank = TRUE;" in vpsdrv_captureVip.c , but It is no useful.

why?
