TDA4VM：yuv422 convert node

Hi TI expert,

Are there any supported nodes for converting yuv422 to rgb565? Please help us confirm.

How do we need to implement this function?

Looking forward to reply, thank you

Regards,

Barry

Hi Barry,

Yes, you can use DSS M2M node for this purpose. DSS does support input as YUV422 interleaved and output RGB565.

There isn't any example in the SDK for this exact usecase, but node is supported, so we just need to provide input and output image with the correct format.

Brijesh

Hi Brijesh,

thank you for your reply,

We are doing:

PDK-RTOS:processor-sdk-rtos-j721e-evm-08_06_00_12

PDK-LINUX:processor-sdk-linux-08_06_00

After I used m2m node to set the data type to TIVX_DF_IMAGE_RGB565 in run_app_multi_cam.sh, the error was reported as follows:

When I add TIVX_DF_IMAGE_RGB565,graph started working.

kernels_j7/hwa/host/vx_display_m2m_host.c:

Hi Barry,

We will have to check if it is really supported in OpenVX node, even if it is not, it should be easy to add in the node, as driver already supports it. 

Rgds,

Brijesh 

Hi Brijesh,

Another thread never gets updated.

Please tell me how we should modify M2M to convert YUV422 to RGB565?

Looking forward to your reply.

Regards,

Barry

Hi Barry,

Is it possible to get the output image, not jpg, to understand the output? 

I see display m2m node does support this format, so it should work.

switch (obj_desc_img->format)
{
case (vx_df_image)TIVX_DF_IMAGE_RGB565:
format->dataFormat = FVID2_DF_BGR16_565;
format->pitch[FVID2_RGB_ADDR_IDX] = (uint32_t)obj_desc_img->imagepatch_addr[0].stride_y;
break;

Regards,

Brijesh

Hi Brijesh,

thank you for your reply.

Our goal is to display it normally on the LCD, but the display we see now is abnormal;

Because the screen is RGB565, we now want to convert the captured YUV422 into RGB565 format for output before DSI output.

When we set the output to RGB565, the resulting display changes, but is still abnormal, such as 2804.tie2e1. zip

2273.tie2e1.zip

Our addition and call to M2M is as shown in the code:

We are on SDK8.6

So can you tell me what's wrong? Thanks

Hi Barry,

The above patch looks fine to me.

After running the graph, can you please share the value at the register offset 0x04AF0020? This will tell us if the WB pipeline is configured correctly.
