Hello,

 

I am facing issue with resolution and scrolling videos with ADV7182.

CVBS Input signals are connected to Ain1(CVBS +ve) & Ain2(CVBS -ve).

I can able to see the videos in full screen without scrolling issues at resolution 320x240.

 

The videos taken with the resolution mentioned below are displayed twice in two splitted screen horizontally without scrolling issue.

640x480

720x480

 

The videos taken with the resolution mentioned below are with scrolling issue continuously and cannot see the videos clearly.

720x576

800x600 and higher..

 

I used the adv7182 scripts provided in the link "http://ez.analog.com/docs/DOC-2633".

Please correct me, whether my configuration settings are done properly as mentioned below or any other additional settings is needed in order to make it work properly?
