V210

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 - 20 and 20 - 30, 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: U block 1, bits 10 - 20: Y block 1, bits 20 - 30: V block 2, bits 0 - 9: Y block 2, bits 10 - 20: U block 2, bits 20 - 30: Y block 3, bits 0 - 9: V block 3, bits 10 - 20: Y block 3, bits 20 - 30: U block 4, bits 0 - 9: Y block 4, bits 10 - 20: V block 4, bits 20 - 30: Y

In addition the start of each line is aligned to a multiple of 64 (or possible 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.
