Hello All,

I want to overlay a buffer on display link for which I have created a following usecase,

""""""""""""""""

NetworkRx (A15) -> Alg_Plugin (DSP1) -> Display_Video

OverlayLink (IPU1_0) -> Display_Grpx

""""""""""""""""

OverlayLink is similar to GrpxLink of Vision SDK. But I have used data format type as "SYSTEM_DF_BGR24_888" instead of "SYSTEM_DF_BGR16_565" or "SYSTEM_DF_BGRA16_4444"

In the OverlayLink, I have ported C++ code for overlaying some data. To draw the overlay on display which Vision SDK functions shall I use as the dataformat is SYSTEM_DF_BGR24_888.

I am not able to use "Draw2D_drawPixel" function as there is not support for SYSTEM_DF_BGR24_888 format.

Is there any other function available in Vision SDK which I can use for drawing pixels of SYSTEM_DF_BGR24_888 dataformat.

Hi,

Are you removing the below assert from the code?
UTILS_assert(pPrm->grpxBufInfo.dataFormat == SYSTEM_DF_BGR16_565
||
pPrm->grpxBufInfo.dataFormat == SYSTEM_DF_BGRA16_4444
);

Hi Anuj,

Yes I have removed it and added below,

UTILS_assert(pPrm->overlayBufInfo.dataFormat == SYSTEM_DF_BGR24_888);

Hi,

I found that with overlayLink I need to use one of the below data formats only,
SYSTEM_DF_BGRA16_4444
SYSTEM_DF_BGR16_565
SYSTEM_DF_YUV422I_YUYV
SYSTEM_DF_YUV420SP_UV

So I used SYSTEM_DF_BGR16_565 data format & Draw2D_drawPixel() with some minor modifications in my code to make it work.

Abhay
