How to get UYVY data from capture?

Other Parts Discussed in Thread: DM3730

Hi My ctm report that in DVSDK, the encoder requires UYVY input, but the capture gives YUYV. Currently they need to use ARM to convert the data, could you advise how to modify the data format from capture side?

Hi Eason,

It is important to describe your full pipeline because various parts of the pipeline provides various abilities for color conversions. For example the previewer has abilities for color conversions by configuration if it presents in the pipeline. Also it is important what is the type of the sensor and what color format it gives (GRGB or YUYV or .... ). In some of the sensors the color format is configurable.

Hi，

it is DVSDK , which I am not familiar. We actually dont know how the pipeline is.

Image sensor is OV2715, whch is raw output only.

Hi, Eason

As I know, you can configure the OV chip reg to switch YUYV to UYVY, I think it would be the easy way.

Thanks & Best Regards,

Stephen

OV2715 has HS/VS connected to DM3730.

Hi Eason,
The Camera ISP VPBE preview module is responsible for transforming data from a RAW image sensor into YUV422 data. You can use the preview module settings to get color conversion.
