Resolve IO Encode SDK: 16-bit clrYUVp 420 gives broken image

I'm using the DaVinci Resolve IO Encode SDK (https://resolve.cafe/developers/encodeplugin/).

Requesting 16-bit clrYUVp 4:2:0 (pIOPropColorModel=clrYUVp, pIOPropHSubsampling=2, pIOPropVSubsampling=2, pIOPropBitsPerSample=16) gives a broken image. Requesting 4:2:2 seems fine.

Here's a dump of both buffers of a single image: https://drive.google.com/file/d/1Aq5lvL ... sp=sharing
The dump contains 4 files:
dump420.raw : dump of 16-bit clrYUVp 4:2:0
dump422.raw : dump of 16-bit clrYUVp 4:2:2
dump420_8.raw : data of dump420.raw with each 16-bit value converted to 8-bit (for easier viewing)
dump422_8.raw : data of dump422.raw with each 16-bit value converted to 8-bit (for easier viewing)

Attached is an image using a raw viewer. The 422 image is fine, Y plane first followed by U/V, but 420 is completely broken somehow.

Please advise.

Hi Balázs,
Did you find the source of your problem or how to work around the bug ?

The problem is with Resolve giving a broken image, I found no solution to fix that from my end. My workaround is that I simply avoid requesting 16-bit YUV 420 from Resolve.

Ouch sorry about that. Are there others pixel formats who appear to be broken according to your experience ?

I haven't encountered others, but I haven't tried them all.
Why do you ask, do you have the same issue? Can you reproduce?

I might test it at some point ! I'm interested in this export SDK too
