DVRRDK 04.00.00.03,dm8168,display link前面可以是select link吗?

我设置display link前面是swms link就可以运行,如果前面是select link,就提示错误,无法运行:

Int32 DisplayLink_drvSetFmt(DisplayLink_Obj * pObj, FVID2_Format *pFormat)
{
    Int32 status;

    /* For the DEI Display instances, set the DEI params */
    if (DisplayLink_drvIsDeiDisplayDrv(pObj))
    {
        status = DisplayLink_drvSetDeiDispPrms(pObj, pFormat);
    }
    else
    {
        status = FVID2_setFormat(pObj->displayHndl, pFormat);
    }

    UTILS_assert(status == FVID2_SOK);
    return(status);
}

卡在assert函数。

  • Nick,

    你的select link输出是YUV422I的数据么?

    下面是select link相关e2e讨论,供参考:

  • 是的,swms输出接的merge,再连接select.

    swms--->|              |         |               | --------->hdmi display link

                     |  merge | ---->|  select |

    swms--->|              |         |              |----------->dvo2 display link
