my target board is adv7180 + iMX51.


I run the mxc_v4l2_tvin to display the video .


when the video source has a short interrupt, the display start rolling for a period.

-- please ref the attached video.


The interrupt is so short, even ADV7180 cannot generate a Lost-Lock signal.

It seems that the camera interface cannot re-sync the input.


Is there any way to fix this problem ?

to detect it or force re-syncing ?
