Problem with NTSC video

Hello!

 

I'm trying to integrate the TW9910 and SABRE LITE, and have a problem with the NTSC video format. The video seems to be floating in time: for about 16 seconds it is correct, then for about 16 seconds it looks like the fields are mixed (but it is only seen on the moving elements, the background looks fine), and so on. Please check the images attached - both cases are illustrated.

 

The versions of software are: GStreamer-imx Plugins 0.11.1, Linux 3.14.38 (linux-imx6-boundary-imx_3.14.38_6qp_beta-cec). I'm using following command:

gst-launch-1.0 -v imxv4l2videosrc num-buffers=-1 device=/dev/video0 ! imxipuvideotransform ! imxipuvideosink window-width=720 window-height=480 sync=true

 

I have no idea what causes this strange effect. Could you please help me?
