Iterators of frame’s pixels (YUV planes)

It’s an enum, because frames may have different pixel formats, and you get format-specific iterator in the enum

Variants

YuvPlanes8

Fields

y: RowsIter<'a, u8>

u: RowsIter<'a, u8>

v: RowsIter<'a, u8>

chroma_sampling: ChromaSampling

8-bit YUV (YCbCr, YCgCo, etc.). This is a collection of 3 iterators. Each may have a different size depending on chroma_sampling.

Consult matrix_coefficients() for meaning of these channels

Mono8(RowsIter<'a, u8>)

8-bit grayscale

YuvPlanes16

Fields

y: RowsIter<'a, [u8; 2]>

u: RowsIter<'a, [u8; 2]>

v: RowsIter<'a, [u8; 2]>

chroma_sampling: ChromaSampling

depth: Depth

10/12/16-bit color. Not subsampled. See depth field for actual range of pixels used.

It’s not u16, because it’s not guaranteed to be aligned. Use u16::from_ne_bytes() or ptr::read_unaligned.

Mono16(RowsIter<'a, [u8; 2]>, Depth)

10/12/16-bit grayscale. It’s not u16, because it’s not guaranteed to be aligned. Use u16::from_ne_bytes() or ptr::read_unaligned.
