Hi, all
My project have 2 LCD output. Refer to the "chains_lvdsVipDualCam_DualDisplay" usecase I write a configuration here.
Void chains_vipMultiCamEncodeAdasDualDisplay_SetDisplayLinkPrms (
DisplayLink_CreateParams *pDpi1Prm,
DisplayLink_CreateParams *pDpi2Prm,
UInt32 width, UInt32 height)

}
Then I use "dss_clockdumps.sh" script to dump the clock. I find that the LCD2 clock overlay LCD1, and LCD1 clock is 0Hz.

Is there any problem with my configuration? Please help me to check it.
