Hi,

HDVPSS register setting is under NDA. You don't need HDVPSS register settings for adding TVP5147 support. You can go throughhttp://processors.wiki.ti.com/index.php/DM81xx_AM38xx_Adding_External_Decoders_to_V4L2_Capture_Driver app note on how to support TVP5147. Many people on forum have achieve this you can google it and find it relevant information.

vout0 is connected to 24bits LCD. I want to capture the VIN1 video display on the LCD. my queston is:

1. Is need to modify M3 firmware?

2. How to use QT display the VIN1 video?

Hi, Hardik.

I need your help. I have a urgent problem. We use RDK2.8 8168, and use the usecase cap-nsf-dei-display.

I set nsfPrm.bypassNsf = FALSE and TRUE, but the image in screen is same. It seems the Nsf doesn't work.

I don't know what's wrong.

Can you help me?
