Struct openh264::decoder::DecodedYUV

pub struct DecodedYUV<'a> { /* private fields */ }

Frame returned by the Decoder and provides safe data access.

Implementations

impl<'a> DecodedYUV<'a>

pub fn y_with_stride(&self) -> &'a [u8]

Returns the Y (luma) array, including padding.

You can use strides_yuv() to compute unpadded pixel positions.

pub fn u_with_stride(&self) -> &'a [u8]

Returns the U (blue projection) array, including padding.

You can use strides_yuv() to compute unpadded pixel positions.

pub fn v_with_stride(&self) -> &'a [u8]

Returns the V (red projection) array, including padding.

You can use strides_yuv() to compute unpadded pixel positions.

pub fn dimension_rgb(&self) -> (usize, usize)

Returns the unpadded, image size in pixels when using write_rgb8().

pub fn dimension_y(&self) -> (usize, usize)

Returns the unpadded Y size.

This may or may not be smaller than the image size.

pub fn dimension_u(&self) -> (usize, usize)

Returns the unpadded U size.

This is often smaller (by half) than the image size.

pub fn dimension_v(&self) -> (usize, usize)

Returns the unpadded V size.

This is often smaller (by half) than the image size.

pub fn strides_yuv(&self) -> (usize, usize, usize)

Returns strides for the (Y,U,V) arrays.

pub fn timestamp(&self) -> Timestamp

Timestamp of this frame in milliseconds(?) with respect to the video stream.

pub fn write_rgb8(&self, target: &mut [u8])

Writes the image into a byte buffer of size w*h*3.

Panics

Panics if the target image dimension don’t match the configured format.

pub fn write_rgba8(&self, target: &mut [u8])

Writes the image into a byte buffer of size w*h*4.

Panics

Panics if the target image dimension don’t match the configured format.
