A8送入yuv420sp的1080P的数据到VideoM3 进行jpeg编码后，然后在传到A8，发现图像有问题，图像是绿的，将jpeg从工具在转换到yuv420sp，用yuv工具看，发现Y分量是正确的，UV分量有问题；哪位高手帮忙看下；

link的流程如下：
A8--->IpcFramesOutLink-->videoM3(jpeg编码)->A8
建IpcFramesOutLink的代码如下，link建好后，调用IpcFramesOutLink_putFullVideoFrames 将yuv420sp的数据送入到IpcFramesOutLink：
  A8SysLinkInfo.numCh = 1;
        A8SysLinkInfo.chInfo[0].bufType = SYSTEM_BUF_TYPE_VIDFRAME;//0;
        A8SysLinkInfo.chInfo[0].codingformat = 0;
        A8SysLinkInfo.chInfo[0].dataFormat = SYSTEM_DF_YUV420SP_UV;
        A8SysLinkInfo.chInfo[0].memType = SYSTEM_MT_NONtiLEDMEM;//0;
        A8SysLinkInfo.chInfo[0].startX = 0;
        A8SysLinkInfo.chInfo[0].startY = 0;
        A8SysLinkInfo.chInfo[0].width = g_ImageWidth;  //1920
        A8SysLinkInfo.chInfo[0].height = g_ImageHeight;  //1080
        A8SysLinkInfo.chInfo[0].scanFormat = SYSTEM_SF_PROGRESSIVE;//1;
        A8SysLinkInfo.chInfo[0].pitch[0] = g_ImageWidth;
        A8SysLinkInfo.chInfo[0].pitch[1] = g_ImageWidth;
        A8SysLinkInfo.chInfo[0].pitch[2] = 0;
  
   //link1
        create_host_frameout_link(ipcFramesOutHostId, ipcFramesInVideoId, A8SysLinkInfo);
 
create_host_frameout_link函数如下： 
  
void create_host_frameout_link(UInt32 ipcFramesOutHostId,  UInt32 nextLinkId,System_LinkQueInfo  queInfo)
[
        IpcFramesOutLinkHLOS_CreateParams  ipcFramesOutHostPrm;
        MULTICH_INIT_STRUCT(IpcFramesOutLinkHLOS_CreateParams ,ipcFramesOutHostPrm);
        ipcFramesOutHostPrm.baseCreateParams.noNotifyMode = FALSE;
        ipcFramesOutHostPrm.baseCreateParams.notifyNextLink = TRUE;
        ipcFramesOutHostPrm.baseCreateParams.notifyPrevLink = FALSE;
        ipcFramesOutHostPrm.baseCreateParams.inQueParams.prevLinkId = SYSTEM_LINK_ID_INVALID;
        ipcFramesOutHostPrm.baseCreateParams.inQueParams.prevLinkQueId = 0;
        ipcFramesOutHostPrm.baseCreateParams.outQueParams[0].nextLink = nextLinkId;
  
        ipcFramesOutHostPrm.baseCreateParams.numOutQue=1;
        ipcFramesOutHostPrm.baseCreateParams.notifyProcessLink=FALSE;
        ipcFramesOutHostPrm.cbFxn = rdk_frames_out_cbfxn;
        ipcFramesOutHostPrm.cbCtx = NULL;
        gVdisModuleContext.ipcFramesOutHostId = ipcFramesOutHostId;
        ipcFramesOutHostPrm.inQueInfo = queInfo ;
        System_linkCreate(ipcFramesOutHostId, &ipcFramesOutHostPrm, sizeof(ipcFramesOutHostPrm));
]
