In the cover letter I mention the gstreamer names where available (this 
particular format is not in gstreamer). AMD has these in their zynqmp 
documentation 
(https://docs.amd.com/r/en-US/ug1085-zynq-ultrascale-trm/Video-Packer-Format).

XVUY2101010 is YUV444_10BPC in AMD docs.

X403 is Y444_10LE32 in gstreamer, and YV24_10BPC in AMD docs.

I'm not sure you'll have much more luck googling with those names, 
though =).
