How to set swMs to crop the picture?

Strachey

Hi,

I use sclr to crop the picture successfully by setting the varialbe pDrvChPrm->srcCropCfg->cropStartX、pDrvChPrm->srcCropCfg->cropStartY、pDrvChPrm->srcCropCfg->cropWidth and pDrvChPrm->srcCropCfg->cropHeight in the function SclrLink_drvCreateFvidObj. I used the chain is

ipcBitsOutHost -> ipcBitsInVideo -> dec -> ipcOutVideo -> ipcInVpss -> sclr -> display[0]

And the result is

Now I want to use swMs instead of sclr to crop the picture.And I want to use the chain is

ipcBitsOutHost -> ipcBitsInVideo -> dec -> ipcOutVideo -> ipcInVpss -> select -> swMs[0] -> display[0]

-> swMs[1] -> display[1]

I set the variable pDrvChPrm->deiCropCfg in the function SwMsLink_drvCreateDeiDrv and pDrvChPrm->srcCropCfg in the function SwMsLink_drvCreateScDrv, but nothing affect at all.

Could you tell me how to use swMs to crop the picture, please?

Thank you!

Best regards!

You can use SYSTEM_SW_MS_LINK_CMD_SET_CROP_PARAM link control cmd to set SwMs crop params. The corresponding MCFW API is Vdis_SetCropParam.

Don't make changes inside SwMs link

Hi,Badri

How I can use the link of SYSTEM_SW_MS_LINK_CMD_SET_CROP_PARAM for cropping?

The structs of SwMsLink_WinInfo,SwMsLink_LayoutWinInfo, SwMsLink_CreateParams.

I know that, SWMS link can use SwMsLink_CreateParams&SwMsLink_CreateParams for layout displaying ,.

But ,I want to use SwMsLink_WinInfo for cropping one winId ,then ,use the cropping area for displaying.

How can I do that?

BR!

Badri：

In addition,in Links_demos:

define:

SwMsLink_LayoutPrm *layoutInfo;
SwMsLink_LayoutWinInfo *winInfo;

winInfo = &layoutInfo->winInfo[winId];

winInfo->width = SystemUtils_align((outWidth*2)/5, widthAlign);
winInfo->height = SystemUtils_align(outHeight/2, heightAlign);
winInfo->startX = winInfo->width*col;
winInfo->startY = winInfo->height*row;
winInfo->bypass = TRUE;
winInfo->channelNum = winId;

If I want to use SwMsLink_WinInfo for cropping ,then layout and display,what should I do to use ?

Parameter of SYSTEM_SW_MS_LINK_CMD_SET_CROP_PARAM is SwMsLink_WinInfo as documented in the link API guide. Refer example usage in

/dvr_rdk/demos/mcfw_api_demos/mcfw_demo/demo_display.c

Vdis_SetCropParam API call

Badri:

I'm sorry to tell you I have no idea how I can use the function of SwMsLink_WinInfo for cropping .

I want to use the links of capture(1080P) ----->swms(cropping(start:(160,160),area(1280,720)) and scaler(1080p))---->display(1080p) for displaying .

Can you help me to achieve it ,and provide for the demo coding?

Thank you very much !
