Hi,

I am trying to capture from an adv7280-m (via MIPI-CSI2 interface) on
an imx6q board.

Here is the configuration:

media-ctl -e "adv7180 2-0020"
/dev/v4l-subdev13

media-ctl -e "ipu1_ic_prpvf capture"
/dev/video2

v4l2-ctl --device /dev/v4l-subdev13 --set-standard PAL
media-ctl -l "'adv7180 2-0020':0 -> 'imx6-mipi-csi2':0[1]"
media-ctl -l "'imx6-mipi-csi2':2 -> 'ipu1_csi1':0[1]"
media-ctl -l "'ipu1_csi1':1 -> 'ipu1_vdic':0[1]";
media-ctl -l "'ipu1_vdic':2 -> 'ipu1_ic_prp':0[1]"
media-ctl -l "'ipu1_ic_prp':2 -> 'ipu1_ic_prpvf':0[1]"
media-ctl -l "'ipu1_ic_prpvf':1 -> 'ipu1_ic_prpvf capture':0[1]"
media-ctl -V "'adv7180 2-0020':0 [fmt:UYVY2X8/720x480 field:seq-tb]"
media-ctl -V "'imx6-mipi-csi2':2 [fmt:UYVY2X8/720x480]"
media-ctl -V "'ipu1_csi1':1 [fmt:AYUV32/800x480]";
media-ctl -V "'ipu1_vdic':2 [fmt:AYUV32/800x480 field:none]"
media-ctl -V "'ipu1_ic_prp':2 [fmt:AYUV32/800x480 field:none]"
media-ctl -V "'ipu1_ic_prpvf':1 [fmt:AYUV32/800x480 field:none]"
v4l2-ctl -d2 --set-fmt-video=field=none

Then when I try to launch Gstreamer:

gst-launch-1.0 v4l2src device=/dev/video2 ! kmssink

Setting pipeline to PAUSED ...
Pipeline is live and does not need PREROLL ...

Does anyone have any ideas as to why the pipeline fails?

Thanks,
