Video rolling during start on IMX6Q Sabre AI board

Hi,

 

I see a video roll for some time (average 2 rolls before the roll finally stops) everytime (It happens on reset, after a power cycle and otherwise)  I try to play an analog video input via gst-launch.

Given at the end is the log of gst-launch when i try to play the analog video input.

Moreover it displays the following warning.

imx-ipuv3 imx-ipuv3.0: IPU Warning - IPU_INT_STAT_5 = 0x00000001 which is the new frame received before EOF interrupt.

 

I had tried making use of the unit_tests/mxc_v4l2_tvin.out program too, with the following command.

./mxc_v4l2_tvin.out -ow 1920 -oh 1080 -ol 10 -ot 20 -f YUYV

Result is the same.

 

I am using a display with resolution of 1920*1080.

 

I had found some links mentioning about the change in the active_top value from 13 to 3 in the mxc_v4l2_capture.c file.

But that too didnt help.

 

I am out of ideas now.

Any help is appreciated.

 

Platform details:

Board   : imx6q sabre ai

kernel version  : 3.0.35

TV chipset  : ADV7180
