hi, 

I use 2 ipu's csi interface connect dual cmos to mem(yuv420), the data flow like this:

cmos0->csi0->ipu0->mem,

cmos1->csi1->ipu1->mem,

ipu0->lcd,

now I can use mxc_v4l_overlay.out to display dual cmos on lcd simultaneously, when capture 1 frame I can get correct yuv420 data but on lcd will black at the moment,

so I want to use vdic on ipu1 to combine cmos0 and cmos1 data from mem and display combined image on lcd, capture image use mem buffer, but I did't find demo in imx-tests (vdic combine 2 data from mem, up and down mode, left and right mode).

 

Sorry for my bad english,THX!

 

PS:bsp is linux+qt 3.10.53, cmos is ov5640(parallel)
