Enum Subsampling
#[repr(i32)]pub enum Subsampling {
Unknown = 0,
S444 = 1,
S422 = 2,
S420 = 3,
S440 = 4,
S411 = 5,
S410 = 6,
}
Expand description
UV subsampling is also specified in the enum value names using J:a:b notation (e.g. 4:2:0 is 1/2 horizontal and 1/2 vertical resolution for U and V). If alpha is present it is not sub- sampled. Note that Subsampling values other than k444 are only valid with PlaneConfig values that have U and V in different planes than Y (and A, if present).
