For memory represenation each component is allocated 16 bits each. Thus each pixel occupies 32bit. Y210: For each component, valid data occupies MSB 10 bits. LSB 6 bits are filled with zeroes. Y212: For each component, valid data occupies MSB 12 bits. LSB 4 bits are filled with zeroes. Y216: For each component valid data occupies 16 bits, doesn't require any padding bits. First 16 bits stores the Y value and the next 16 bits stores one of the chroma samples alternatively. The first luma sample will be accompanied by first U sample and second luma sample is accompanied by the first V sample. The following pixel formats are packed format that follows 4:4:4 chroma sampling. Channels are arranged in the order UYVA in increasing memory order. Y410: Each color component occupies 10 bits and X component takes 2 bits, thus each pixel occupies 32 bits. Y412: Each color component is 16 bits where valid data occupies MSB 12 bits. LSB 4 bits are filled with zeroes. Thus, each pixel occupies 64 bits. Y416: Each color component occupies 16 bits for valid data, doesn't require any padding bits. Thus, each pixel occupies 64 bits.
