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<'_>

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

Formats the value using the given formatter.
