Question：dual cmos combined with vidc to display

[王双]

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)

hi igor,

I check the links you posted and found it only mentioned deinterlace fnuction, but don't find how to combined 2 image in mem by vdic. 

I found [37.4.11.6 Using Combining in the VDIC] in imx6qqrm.pdf,  

and want to do like this, image1 in mem(320x240, yuv420)  image2 in mem(320x240, yuv420), and use vdic to combine these 2 images to image3(320x480, yuv420) or (640x240, yuv420).

I'm not sure dose vdic can do this? Please help me to solve it.

Best regards

Hi yinxin

for such tasks would be more suitable to check combining examples on

ipu-examples release notes - v0.1 | NXP Community

hi igor,

sorry about delay reply, I check the link you posted about ipu-examples.

It seems don't contain demo about combine function, and I seed the project code on github for the newest, it likes the same one.

Would you give me a hand?

best regards
