Tool/software: TI-RTOS

Hi all,

We are using the ADV7182 video decoder on DRA74xx processor through VIP and VPDMA using IPU1. We are using custom driver similar to vision sdks for accessing the VIP/VPDMA.

The frames are captured properly but the video quality captured is very low. The video decoder configuration looks Ok and we are using the recommended configuration from AnalogDevices. 

The input format is y(4:2:0) embedded sync. It is converted to y(4:2:2) before sending to display area.

Looks Odd and Even fields are also properly received . We make minor adjustment in DDR area to change the start address of odd and even field based on field_id. Kindly let us know where there could be issue regarding video quality.

*The image on the right top is the back camera output

With regards,

Jeyaseelan
