DCC Tool raw capture

Tal Postol

Hello

We are using Appro DM8127 IPNC.

We changed the flow to capture 1280x960 raw Bayer 12bit and changed stream 0 (after RZA) to output 640x480 YUV420.

When we capture raw image using DCC tool the saved image is incomplete, meaning we expect to get 1280*960*2=2457600 bytes but the saved image is 614400 bytes.

Please help.

Did you verify your RSZ register configurations. ?

Thanks for the reply,

How this register should affect the raw image.

For my understanding the raw image should be captured before the resizer, actually by ISIF.

Anyway what should I verify in this register.

Thanks.

Did you check the isif register? If they are configured to output 640x480, it will write out 614400 bytes, which is actually equal to 640x480*2.

It seems that the problem is in alg_itk_Link_tsk.c

The raw buffer allocation and transmit logic are using the "out params" which are the parameters for the resizer.
So in my case the sensor/isif params (raw) are 1280x960 and the resizer params are 640x480.

The only case that raw capture will work is if the input size (raw) and output size (YUV after resizer) are the same.
