V3S USB Camera

I started using V3S with implement USB camera on it.
I used Yokto to make the linux image and I added usb video class and ffmpeg to it.
after some weeks at last I get the video.
Because I wanted to have a smooth video I could not get better resoloution of 320x240 from camera. on higher qualities, I has delay in video.

video (LCD Resoloution: 480x272 - but input resoloution from camera is 320x240)

after that, I designed a PCB for it and I used 54 pin FPC connector for 3.5 inch LCD.

But after assemble the hardware, the colors on picture was not correct. It is like a burned picture!
I'm sure that my board has not problem (because I made a 54-to-40 pin converter and I still have a good output on 4.3inch LCD!)

I'm still working on it. but I could not get the problem!

@alizx
这种情况，看起来可能 R/G/B 上面有一两根线断路或者短路了。

Thanks for your reply.
I check the hardware. there is no issue there. in addition, I tested 4.3 inch LCD (I designed a simple 54-to-40 pin converter) and there was no issue!

@哇酷小二
a) I get a snapshot with v3s from usb camera and I checked it on my pc. it's ok
b) I show an image on this LCD but it is not ok. it's like output of usb cam.
