TVP5150 streaming issue

Other Parts Discussed in Thread: TVP5150, TVP5150AM1

Hi,


We are using ti-ezsdk_dm816x-evm_5_05_02_00 and Linux 2.6.37 software and

We are using our customized DM8168 board with TVP5150 decoder chip for video capture.

When we run saLoopBack application, the video is successfully streamed from the TVP5150 decoder chip, but we are seeing some interlaced lines on the display during the motion, not observed in the static area.


Please help us to know what could be the reason for the lines and how could we resolve it.

Regards,

Geetha
