DM385 MJPEG crop issue - Is startY work?

Sung-IL

Dear Team,

When my customer tried to crop height of input image in the MJPEG encoder, they see the mismatched color image as attached and it looks the crop was not applied to UV field. Could you please check this on your side and let me know the solution?

my customer is using IPNC RDK SW v3.8.0 and using JPEG encoder integrating in IPNC RDK SW v3.8.0, and their settings for crop are as below.

~~~~~~~~~

pChObj->algObj.algDynamicParams.startX = 0

pChObj->algObj.algDynamicParams.startY = 60

pChObj->algObj.algDynamicParams.inputWidth= 640

pChObj->algObj.algDynamicParams.inputHeight = 360

inputBufDesc->imageRegion.topLeft.x = 0

inputBufDesc->imageRegion.topLeft.y = 60

inputBufDesc->imageRegion.bottomRight.x = 640

inputBufDesc->imageRegion.bottomRight.y = 420

inputBufDesc->activeFrameRegion.topLeft.x = 0

inputBufDesc->activeFrameRegion.topLeft.y = 60

inputBufDesc->activeFrameRegion.bottomRight.x = 640

inputBufDesc->activeFrameRegion.bottomRight.y = 420

Thanks and Best Regards,

SI.

Hi Sung-IL,

We have verified with provided configuration on our standalone test application and did not observe any chroma patches for jpeg image.

1.which codec release version is used in your RDK?

2.I am suspecting UV buffer pointer updation might be not proper.

Could you please check inputBufDesc.planeDesc[1].buf for UV buffer ?

Thanks Harris,

The MJPEG encoder version is 'REL.500.V.MJPEG.E.IVAHD.01.00.15.01' in IPNC RDK v3.8.0.

As for the UV buffer pointer, I think UV buffer pointer was not move to right position accoding to startY value.

There is no issue when startY is '0', but this issue occurred when startY is not '0'.

Either when startY is '0' or not '0', UV pointer should point same position, right?

Is it possible to attach your result images?(original and after cropping).

Thanks and Best Regards,

SI.
