Struct Nv12Planes 

pub struct Nv12Planes {
    buf: Vec<u8>,
    start: [usize; 2],
    pub stride: [usize; 2],
    pub width: usize,
    pub height: usize,
    in_place: bool,
}

A frame’s 8-bit 4:2:0 picture as NV12, a luma plane and an interleaved chroma one, laid out as an x264 session encodes it in place (x264_param_input_layout): each plane stride bytes a row within a buffer padded and aligned as x264’s own frames are, which x264 reads without copying it and writes the padding of. Tightly packed where the build has no x264, whose OpenH264 session takes no such picture.

Fields

buf: Vec<u8>

start: [usize; 2]

stride: [usize; 2]

width: usize

height: usize

in_place: bool

Implementations

impl Nv12Planes

pub fn new(width: usize, height: usize) -> Self

Black planes for a width x height picture, both even.

pub fn planes(&self) -> (&[u8], &[u8])

The luma and chroma planes from their first pixel, stride bytes a row for the picture’s rows.

pub fn planes_mut(&mut self) -> (&mut [u8], &mut [u8])

Self::planes, to write.

pub fn id(&self) -> *const u8

The address of the first luma pixel, which names the picture to the session holding it (H264EncoderWrapper::held_input).

fn extents(&self) -> (Range<usize>, Range<usize>)
