TDA2PXEVM: Camera Format Support in Vision SDK

Shantanu Joshi

Part Number: TDA2PXEVM

Hello All

1. We have 3 LVDS camera models below with different output formats:

We need to know whether Vision SDK provided camera capture link support above frame format capture. Which link shall be used for this purpose?

Camera model 1: Parallel 8-bit YCbCr data (uyvy)

Camera model 2: RAW/YUV422

Camera model 3: YUV422 8BITS (PoC LVDS)

2. We need to do frame format conversion as below. Does VPE support these conversions?

Camera model 1: Parallel 8-bit YCbCr data (uyvy) -> YUV422I YUYV

Camera model 2: RAW/YUV422 -> YUV422I YUYV

Camera model 3: YUV422 8BITS (PoC LVDS) -> YUV422I YUYV

Inputs, Suggestions would be of great help.

Regards

Shantanu,

Few questions,

1, what is RAW format? is it bayer data?

2, what is YUV422 8BITS (PoC LVDS) format?

Hello Brijesh,

Which RAW format is used is not clear so far.

Below information on sensors used in these cameras:

Camera model 1: Parallel 8-bit YCbCr data (uyvy) (Sony ISX 019)

Camera model 2: RAW/YUV422 (Omnivision OV10640)

Camera model 3: YUV422 8BITS (PoC LVDS) (Sony ISX 016)

Shantanu,

For RAW data, you need to use ISP to get it converted into viewable format.

All of these formats can be captured.

But only YUV420/422 format can be processed in VPE.

Hi Shantanu,

You could use Iss capture to capture over CSI interface and VIP capture to capture over parallel interface.

What is SP format? If it is YUV420SP, yes, VPE can support YUV422 to YUV420 format.

Hello Brijesh,

Is it possible to extend the VPE Link to support below formats

SYSTEM_DF_YUV422I_YVYU

SYSTEM_DF_YUV422I_VYUY

SYSTEM_DF_YUV422SP_VU

SYSTEM_DF_YUV422P

and if Yes, then how shall I add the support, will it be added by adding cases for above formats in vpeLink_drvCommon.c.

Shantanu,

Driver support all but last formats, so link can also support.

Do you mean full planar format by 422P? that's not supported.

Hello Brijesh

From Above I understand that apart from YUV422P all other formats are supported and can add support for that in VPE link and driver as well.

I am closing the the thread. Thank you so much for the response provided.

Shantanu
