Expand description
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
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
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
.

§
chroma_sampling: ChromaSampling
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
.
