Enum TYuvSamplingPattern

4:2:0 sampling format. 4 luminance sample positions correspond to one chrominance sample position. The four luminance sample positions are on the corners of a square. The chrominance sample position is vertically half-way of the luminance sample positions and horizontally aligned with the left side of the square. This is the MPEG-2 and the MPEG-4 Part 2 sampling pattern.

4:2:0 sampling format. 4 luminance sample positions correspond to one chrominance sample position. The four luminance sample positions are on the corners of a square. The chrominance sample position is vertically and horizontally in the middle of the luminance sample positions. This is the MPEG-1 sampling pattern.

4:2:0 sampling format. 4 luminance sample positions correspond to one chrominance sample position. The four luminance sample positions are on the corners of a square. The chrominance sample position colocates with the top-left corner of the square. This sampling format is one of the options in Annex E of H.264 | MPEG-4 AVC.

4:2:2 sampling format. 2 luminance sample positions correspond to one chrominance sample position. The luminance sample positions reside on the same pixel row. The chrominance sample position is co-located with the left one of the luminance sample positions. This is the MPEG-2 4:2:2 sampling pattern.

4:2:2 sampling format. 2 luminance sample positions correspond to one chrominance sample position. The luminance sample positions reside on the same pixel row. The chrominance sample position is in the middle of the luminance sample positions. This is the MPEG-1 4:2:2 sampling pattern.
