Capturing analog video with imx6q and tvp5150 decoder

Question asked by dogan ugurlu on May 30, 2019

Hi Everyone

 

I am working on a project which is about capture video.

 

When the system starts(Video input enable) everything is good.  The video seems to start at top of the monitor. Everything is flawlessly but the system starts(video input disable) and then the video cable connects to the system. The video seems to start at the CUSTOM location of the monitor.  The video starts sometimes the center of the monitor, sometimes bottom of the monitor.

 

How can ı solve this problem?

 

 

Video input source:   NTSC
Video input decoder: TVP5150
Video input encoder: adv7391

Linux Kernel: 3.14.28
