The v210 format is a packed YUV 4:2:2 (UYVY) format with 10 bits per component.
Data is stored in blocks of 32 bit values in little-endian.
Each such block contains 3 components, one each in bits 0 - 9, 10 - 19 and 20 - 29, the remaining two bits are unused.
Since UYVY consists of 4 components that represent two pixels, which of those bits correspond to which component makes a pattern that repeats every 4 32-bit blocks:
block 1, bits 0 - 9: U0+1 block 1, bits 10 - 19: Y0 block 1, bits 20 - 29: V0+1 block 2, bits 0 - 9: Y1 block 2, bits 10 - 19: U2+3 block 2, bits 20 - 29: Y2 block 3, bits 0 - 9: V2+3 block 3, bits 10 - 19: Y3 block 3, bits 20 - 29: U4+5 block 4, bits 0 - 9: Y4 block 4, bits 10 - 19: V4+5 block 4, bits 20 - 29: Y5
In addition the start of each line is aligned to a multiple of 128 bytes, where unused blocks are padded with 0.
Unused parts of a partial (i.e. last) block do not seem to contain any specific value.
