This pixel format is current used in the rockchip platform. I think any model
higher than rk322x would support this pixel format. Xilinx may support
it but I am not sure.

More than a year ago, I post the patch Add pixel formats for 10/16 bits
YUV video to the mail list, it has been update to version 8, but they
are not merged yet. So I decide to submit these independent patches,
I hope that they would be reviewed and merged in a short time.

I have added a patch to Gstreamer and it is merged now.
Any future information can be found on the bugzilla of the Gstreamer:
https://bugzilla.gnome.org/show_bug.cgi?id=795462

I have verified this patch on the rk3288, with the following command:
gst-launch-1.0  filesrc location=conv_3840_2160.nv12_10le40 ! \
 rawvideoparse format=81 width=3840 height=2160 ! imagefreeze ! kmssink

Also you can find video sample video on above page, but you may need to
set the plane offset and stride when you are using the other files.
