NV21 is the same but with weaved V and U values. The 12 in NV12 refers to 12 bits per pixel. NV12 has a half width and half height chroma channel, and therefore is a 420 subsampling. NV16 is 16 bits per pixel, with half width and full height. aka 422. NV24 is 24 bits per pixel with full sized chroma channel. aka 444. When the image format is planar the bytesperline value applies to the first plane and is divided by the same factor as the width field for the other planes. For example the Cb and Cr planes of a YUV 4:2:0 image have half as many padding bytes following each line as the Y plane.

Attached are a script and output file showing my system's failure to pass 3G and 12G video through using NV16 (4:2:2). You will see where I have commented out where NV12 (4:2:0) "works". What am I doing wrong? Wrong format specification to xmedia-ctl? Incorrect format specification in the capabilities filter? Any guidance is appreciated.
From our 10-bit input processing (see: SDI Video to 10 Bit H265 MPEG) you will want to change to video format NV16_10LE32 (from NV12), in addition to the revised xmedia-ctl configuration of the input. This was apparently unavailable in the 2018.3 release.
Since VPU output format is YUV, to show the image to display, need to convert the format to RGB and resize. This demo use G2D to do the conversion. Make sure gpu-viv-bin-mx6q is built into your rootfs. About more information of G2D, please refer to i.MX_6_G2D API.pdf. In ltib, extract GPU lib by $ ./ltib -m prep -p gpu-viv-bin-mx6q . 3.

The Y plane is followed immediately by an array of unsigned char values that contains packed U (Cb) and V (Cr) samples. When the combined U-V array is addressed as an array of little-endian WORD values, the LSBs contain the U values, and the MSBs contain the V values.
