关于海思3519拓展通道的属性设置的疑问

本帖最后由 wfjdemmye 于 2016-11-28 17:08 编辑

我创建了两个VO输出，然后一个绑定VPSS，一个绑定VO作为一个拓展通道。

现在我想不影响主通道的情况下，去放大拓展通道； 附代码：

创建VO双通道输出： for (i = 0; i < u32WndNum; i++) { //if(u32WndNum>2) /if(i>2) { stChnAttr.stRect.s32X = ALIGN_BACK((u32Width / u32Square) (i % u32Square), 2); stChnAttr.stRect.s32Y = ALIGN_BACK((u32Height / u32Square) (i / u32Square), 2); stChnAttr.stRect.u32Width = ALIGN_BACK(u32Width / u32Square, 2); stChnAttr.stRect.u32Height = ALIGN_BACK(u32Height / u32Square, 2); }/ if(i==0) { stChnAttr.stRect.s32X = 0; stChnAttr.stRect.s32Y = 0; stChnAttr.stRect.u32Width = 1920; stChnAttr.stRect.u32Height = 1080;

        }
        else if(i==1)
        {
            stChnAttr.stRect.s32X       = 0;
            stChnAttr.stRect.s32Y       = 0;
            stChnAttr.stRect.u32Width   = 400;
            stChnAttr.stRect.u32Height  = 200;
        }
        else if(i==2)
            {
            stChnAttr.stRect.s32X       = 800;
            stChnAttr.stRect.s32Y       = 0;
            stChnAttr.stRect.u32Width   = 500;
            stChnAttr.stRect.u32Height  = 300;

            }
        else if(i==3)
            {
            stChnAttr.stRect.s32X       = 0;
            stChnAttr.stRect.s32Y       = 500;
            stChnAttr.stRect.u32Width   = 500;
            stChnAttr.stRect.u32Height  = 300;
            }

    stChnAttr.u32Priority       = 0;
    stChnAttr.bDeflicker        = HI_FALSE;

    printf("stChnAttr.stRect.s32X:%d,u32Width:%d,u32Square:%d,i:%d\n",stChnAttr.stRect.s32X,u32Width,u32Square,i);

    s32Ret = HI_MPI_VO_SetChnAttr(VoLayer, i, &stChnAttr);//MAX 8
    if (s32Ret != HI_SUCCESS)
    {
        printf("%s(%d):failed with %#x!\n", \
               __FUNCTION__, __LINE__,  s32Ret);
        return HI_FAILURE;
    }
    s32Ret = HI_MPI_VO_EnableChn(VoLayer, i);
    if (s32Ret != HI_SUCCESS)
    {
        SAMPLE_PRT("failed with %#x!\n", s32Ret);
        return HI_FAILURE;
    }

绑定VPSS的过程差不多，就不写啦：-------------------------

显示通道VO_chn1: s32Ret = HI_MPI_VO_SetAttrBegin(0);

s32Ret = HI_MPI_VO_SetChnAttr(0, 1, &VoChnAttr);
if (HI_SUCCESS != s32Ret)
{
    printf("vo set chn  attr failed!:%x \n",s32Ret);
    return s32Ret;
}
s32Ret = HI_MPI_VO_ShowChn(0,1);
s32Ret = HI_MPI_VO_SetAttrEnd(0);
    if (HI_SUCCESS != s32Ret)
{
    printf("vo set chn %d attr failed!:%x \n",s32Ret);
    return s32Ret;
}
    return HI_SUCCESS;

隐藏通道VO_chn1: VO_CHN_ATTR_S VoChnAttr; s32Ret = HI_MPI_VO_SetAttrBegin(0); VoChnAttr.bDeflicker = HI_TRUE; VoChnAttr.u32Priority = 1; VoChnAttr.stRect.s32X = 0; VoChnAttr.stRect.s32Y = 0; VoChnAttr.stRect.u32Width = 1920; VoChnAttr.stRect.u32Height = 1080; s32Ret = HI_MPI_VO_SetChnAttr(0, 0, &VoChnAttr); if (HI_SUCCESS != s32Ret) { printf("vo set chn attr failed!:%x \n",s32Ret); return s32Ret; } s32Ret = HI_MPI_VO_ShowChn(0,0); if (s32Ret != HI_SUCCESS) { printf("vo hide channel failed!:%x\n", s32Ret); return HI_FAILURE; } s32Ret = HI_MPI_VO_HideChn(0,1); if (s32Ret != HI_SUCCESS) { printf("vo hide channel failed!:%x\n", s32Ret); return HI_FAILURE; } s32Ret = HI_MPI_VO_SetAttrEnd(0);

设置拓展通道放大： VPSS_CROP_INFO_S pstCropInfo; memset(&pstCropInfo,0,sizeof(VPSS_CROP_INFO_S)); HI_S32 rel=HI_MPI_VPSS_GetExtChnCrop(0,4, &pstCropInfo); if(rel != HI_SUCCESS) { printf("HI_MPI_VPSS_GetGrpCrop ERROR:%x\n",rel); return rel; }

//printf("pstCropInfo.bEnable is close and open it \n");
pstCropInfo.bEnable = HI_TRUE;  
pstCropInfo.stCropRect.s32X =xPos-20;
pstCropInfo.stCropRect.s32Y =yPos-10;

pstCropInfo.stCropRect.u32Width = 40;
pstCropInfo.stCropRect.u32Height = 20;

if(pstCropInfo.stCropRect.s32X<=0)pstCropInfo.stCropRect.s32X=0;
else if(1920-pstCropInfo.stCropRect.s32X<=40)pstCropInfo.stCropRect.s32X=1880;
if(pstCropInfo.stCropRect.s32Y<=0)pstCropInfo.stCropRect.s32X=0;
else if(1080-pstCropInfo.stCropRect.s32Y<=20)pstCropInfo.stCropRect.s32X=1060;

rel= HI_MPI_VPSS_SetExtChnCrop(0,4, &pstCropInfo);
if(rel != HI_SUCCESS)
{
    printf("HI_MPI_VPSS_SetGrpCrop ERROR:%x\n",rel);
    return rel;
}
return rel;

我在设置放大属性的时候遇到 HI_MPI_VPSS_SetGrpCrop ERROR:a0078003 HI_MPI_VPSS_SetGrpCrop ERROR:a0078003 HI_MPI_VPSS_SetGrpCrop ERROR:a0078003 HI_MPI_VPSS_SetGrpCrop ERROR:a0078003 HI_MPI_VPSS_SetGrpCrop ERROR:a0078003

0xA0078003 HI_ERR_VPSS_ILLEGAL_PARAM VPSS 参数设置无效

请教一下，HI_MPI_VPSS_SetExtChnCrop这个过程的设置是一个什么样的流程才能设置成功，求教一下社区的大神们。
