Struct aom_decode::FrameTempRef

pub struct FrameTempRef<'a>(_, _);

Frame held in decoder’s internal state. Must be dropped before the next call.

Implementations

impl FrameTempRef<'_>

pub fn rows_iter(&self) -> Result<RowsIters<'_>>

Access pixel data

Iterator over rows of image data.

The data can be grayscale (mono) or YUV (YCbCr), so the result is wrapped in an enum

pub fn chroma_sampling(&self) -> Result<ChromaSampling>

Whether image uses chroma subsampling or not

pub fn depth(&self) -> Result<Depth>

How many bits per pixel that is

pub fn color_primaries(&self) -> Option<ColorPrimaries>

What flavor of RGB color this should be converted to

pub fn transfer_characteristics(&self) -> Option<TransferCharacteristics>

That’s basically gamma correction

pub fn matrix_coefficients(&self) -> Option<MatrixCoefficients>

Flavor of YUV used for the pixels

See yuv crate for conversion to RGB.

pub fn range(&self) -> Range

Whether pixels are in 0-255 or 16-235/240 range.

pub fn chroma_sample_position(&self) -> Option<ChromaSamplePosition>

Alignment of the chroma channels

Routines in this library don’t support this detail. Also, chroma subsampling is useless in AV1, so please don’t use it.

Trait Implementations

impl Debug for FrameTempRef<'_>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
