Thanks for the link. I've downloaded the archive and will try building it now.

Edit: The glslangValidator built from the 3.0 archive generates too old SPIR-V files for Warp3D Nova (version 0.0.99, minimum version for Warp3D Nova is 1.0.0).

Comparing with a similar CPU based RGB to YUV420P conversion routine the CPU based one takes about 177 ms for one 1920x1080 32-bit bitmap and the shader based one takes only 2.5 ms.

A 70.8x speed improvement. Nice!

Version 0.0.99 was a draft version, and they completely changed the instruction IDs between that and 1.0.0 (plus other changes). That made supporting the old spec impractical.

Hmm then I must have used a slightly later snapshot.

I'll get back to you on that, sorry for the confusion.
