Hmm... We have already NV12 format at media subsystem side: Documentation/media/uapi/v4l/pixfmt-nv12.rst Did we miss some patch from you? > > For extra detail, the Rockchip variant is fully packed, with no padding > bits, while the Microsoft variant uses 16bits per pixels, with 6bits > padding. It was a mistake to use P010 initially for the Rockchip > format. Yeah, P010 format seems to be a waste of bandwidth. Yet, as we're now having devices using it (via uvcdriver), it would make sense to merge the single plane format for it. I would merge the P016 too, as P010 seems to be just a degradation of it. Ayaka, Would it be possible for you to re-send the P010/P016 documentation for single plane, fixing the typo (simliar -> similar)? Let's not merge the dual plane formats, as we don't need them yet at the Kernel. Thanks, Mauro
