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
