i.MX6DL CSI0 BT656 with FCB-EX2400P scrolling

[iemdey]

Hi,

I am using the FCB-EX2400P's digital output(equivalent to ITU-R BT656) as the imx6dl CSI0 input source.

FCB-EX2400P's settings are all as it's default.

The kernel version is 4.1.15-2.0.1.

My capture command is: gst-launch-1.0 -e imxv4l2src ! imxvideoconvert_ipu ! imxv4l2sink

I can capture frame, but the video is scrolling. See VID_20170329_223945.mp4.

I have tried increase the VSC，but nothing diffrent.  It seems the VSC have no effect.

Is the vsync in BT656 not correct?

Thanks for the Help

Hi deng

please check sect.7.3.8 Recording the TV-in source attached Linux Guide,

it was tested with adv7180. So one can check if FCB-EX2400P provides deinterface

signal and if syncs are true ITU-R BT656.

Best regards
igor
