Colorspace (color model/pixel format). Only subset of them is supported.

From libavformat/yuv4mpegenc.c:

yuv4mpeg can only handle yuv444p, yuv422p, yuv420p, yuv411p and gray8 pixel formats. And using ‘strict -1’ also yuv444p9, yuv422p9, yuv420p9, yuv444p10, yuv422p10, yuv420p10, yuv444p12, yuv422p12, yuv420p12, yuv444p14, yuv422p14, yuv420p14, yuv444p16, yuv422p16, yuv420p16, gray9, gray10, gray12 and gray16 pixel formats.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Cmono

Cmono12

Grayscale only, 12-bit.

C420
