Dpixfmt-m420.rst16 Format with ½ horizontal and vertical chroma resolution, also known as
23 M420 is a YUV format with ½ horizontal and vertical chroma subsampling
24 (YUV 4:2:0). Pixels are organized as interleaved luma and chroma planes.
25 Two lines of luma data are followed by one line of chroma data.
27 The luma plane has one byte per pixel. The chroma plane contains
