求解！！！Hi3516A VPSS和VENC图像处理问题

Crop问题的代码；
VPSS_GRP_ATTR_S stGrpVpssAttr;
VPSS_CHN_ATTR_S stChnAttr;
VPSS_CROP_INFO_S stCropInfo;
HI_S32 s32Ret = HI_SUCCESS;
VPSS_GRP VpssGrp;
VPSS_CHN VpssChn
  
VpssGrp = 0；
VpssChn = 0；
     
stGrpVpssAttr.u32MaxW = 720;
stGrpVpssAttr.u32MaxH = 576;
stGrpVpssAttr.bIeEn = HI_FALSE;
stGrpVpssAttr.bDciEn = HI_FALSE;
stGrpVpssAttr.bNrEn = HI_FALSE;
stGrpVpssAttr.bHistEn = HI_FALSE;
stGrpVpssAttr.enDieMode = VPSS_DIE_MODE_NODIE;
stGrpVpssAttr.enPixFmt = PIXEL_FORMAT_YUV_SEMIPLANAR_422;
     
s32Ret = HI_MPI_VPSS_CreateGrp(VpssGrp, &stGrpVpssAttr);
if(s32Ret != HI_SUCCESS)
{
  return s32Ret;
}
     
s32Ret = HI_MPI_VPSS_GetGrpAttr(VpssGrp, &stGrpVpssAttr);
if(s32Ret != HI_SUCCESS)
{
  return s32Ret;
}
     
stGrpVpssAttr.bIeEn = HI_FALSE;
stGrpVpssAttr.bNrEn = HI_TRUE;
s32Ret = HI_MPI_VPSS_SetGrpAttr(VpssGrp, &stGrpVpssAttr);
if(s32Ret != HI_SUCCESS)
{
  return s32Ret;
}
s32Ret = HI_MPI_VPSS_GetGrpCrop(VpssGrp, &stCropInfo)；
if(s32Ret != HI_SUCCESS)
{
return s32Ret;
}
stCropInfo.bEnable = HI_TRUE;
stCropInfo.enCropCoordinate = VPSS_CROP_ABS_COOR;
stCropInfo.stCropRect.s32X = 180;
stCropInfo.stCropRect.s32Y = 252;
stCropInfo.stCropRect.u32Width = 1920;
stCropInfo.stCropRect.u32Height = 1080;
s32Ret = HI_MPI_VPSS_SetGrpCrop(VpssGrp, &stCropInfo)；
if(s32Ret != HI_SUCCESS)
{
   return s32Ret;
}
s32Ret = HI_MPI_VPSS_GetChnAttr(VpssGrp, VpssChn,&stChn
if(s32Ret != HI_SUCCESS)
{
  return s32Ret;
}
stChnAttr.bFrameEn = 0;
stChnAttr.bSpEn = HI_FALSE;
s32Ret = HI_MPI_VPSS_SetChnAttr(VpssGrp, VpssChn,&stChn
if(s32Ret != HI_SUCCESS)
{
  return s32Ret;
}
s32Ret = HI_MPI_VPSS_EnableChn(VpssGrp, VpssChn);
if(s32Ret != HI_SUCCESS)
{
  return s32Ret;
}
  
s32Ret = HI_MPI_VPSS_StartGrp (VpssGrp);
if(s32Ret != HI_SUCCESS)
{
  return s32Ret;
}

它将VPSS组的分辨率设置为720*576，但是在后面裁剪的时候，裁剪区域大小确实1920*1080.这是为什么呢？
我自己将裁剪区域改小之后就会报get venc stream time out, exit thread错误。

看上去文档自相矛盾了

文档上
HI_MPI_VPSS_SetGrpCrop()

CROP 区域的尺寸不能小于VPSS 最小尺寸要求且不能超过VPSS 最大尺寸。

对比其他文档, 个人认为这个比较靠谱

注意离线/在线模式[/quote]

使用的是离线模式

但是我的CROP区域的尺寸并没有超出这个范围，只是将Region区域改都改小了一点，就会报错。只能往大改。
