DM8127下usecase中加入swMslink拼接出2*2布局，运行后通道0显示异常，其他通道正常

各位好，

我将8127前端从sensor替换成了模拟摄像头输入，link连接方式为capturelink->deilink->nsflink->......！目标顺利完成。

接下来，我希望用马赛克link将四路画面拼接为一副画面，link连接方式为：capturelink->deilink->swmslink->nsflink->......。

但是按照上述目标，我在usecase中修改了代码，但是运行之后窗口1，2，3分别显示通道1，2，3的视频画面正常，但是窗口0显示通道0数据是异常：具体异常如下：1、画面前端有密集的黄色雪花遮挡。2、通道0的视频画面并未经过缩放，画面尺寸明显与其他通道不同。具体显示图像如附件中所示。麻烦各位帮忙分析下问题.

usecase中link连接具体代码如下所示：

//config 5158
numCaptureDevices = 1;
for(i = 0; i < numCaptureDevices; i++)
{

vidDecVideoModeArgs[i].videoIfMode = DEVICE_CAPT_VIDEO_IF_MODE_8BIT;
vidDecVideoModeArgs[i].videoDataFormat = SYSTEM_DF_YUV422P;
vidDecVideoModeArgs[i].standard = SYSTEM_STD_MUX_4CH_D1;
vidDecVideoModeArgs[i].videoCaptureMode =
DEVICE_CAPT_VIDEO_CAPTURE_MODE_MULTI_CH_PIXEL_MUX_EMBEDDED_SYNC;
vidDecVideoModeArgs[i].videoSystem =
DEVICE_VIDEO_DECODER_VIDEO_SYSTEM_AUTO_DETECT;
vidDecVideoModeArgs[i].videoCropEnable = TRUE;//FALSE;
vidDecVideoModeArgs[i].videoAutoDetectTimeout = -1;

} //added ydp
OSA_printf("\n********* ----------------Config Tvp5158---------------- ********\n\n");
Vcap_configVideoDecoder(vidDecVideoModeArgs, numCaptureDevices);//added ydp

以上是swmslink之前的配置代码，另外在马赛克link最后调用的函数Cap_swMsGetDefaultLayoutPrm是我根据ti提供的相应函数自定义的，具体内容如下：

Void Cap_swMsGetDefaultLayoutPrm(int devId, SwMsLink_CreateParams *swMsCreateArgs, Bool forceLowCostScaling)
{
SwMsLink_LayoutPrm *layoutInfo;
SwMsLink_LayoutWinInfo *winInfo;
VDIS_MOSAIC_S *mosaicParam;

if(devId>=VDIS_DEV_MAX)
devId = VDIS_DEV_HDMI;

layoutInfo = &swMsCreateArgs->layoutPrm;

/* init to known default */
memset(layoutInfo, 0, sizeof(*layoutInfo));

mosaicParam = &(gVdisModuleContext.vdisConfig.mosaicParams[devId]);

layoutInfo->onlyCh2WinMapChanged = FALSE;
layoutInfo->outputFPS = 30;
layoutInfo->numWin = 4;

winInfo = &layoutInfo->winInfo[0];
winInfo->width = 960;
winInfo->height = 540;
winInfo->startX = 0;
winInfo->startY = 0;
winInfo->channelNum = 0;
winInfo->bypass = FALSE;

winInfo = &layoutInfo->winInfo[1];
winInfo->width = 960;
winInfo->height = 540;
winInfo->startX = 960;
winInfo->startY = 0;
winInfo->channelNum = 1;
winInfo->bypass = FALSE;

winInfo = &layoutInfo->winInfo[2];
winInfo->width = 960;
winInfo->height = 540;
winInfo->startX = 0;
winInfo->startY = 540;
winInfo->channelNum = 2;
winInfo->bypass = FALSE;

winInfo = &layoutInfo->winInfo[3];
winInfo->width = 960;
winInfo->height = 540;
winInfo->startX = 960;
winInfo->startY = 540;
winInfo->channelNum = 3;
winInfo->bypass = FALSE;
