}

A VP8 key-frame header (RFC 6386 §9). Intra/key-frame fields only — gamut codes no inter-frame state.

Fields

width: u16

Frame width in pixels (the 14-bit field of the uncompressed chunk).

height: u16

Frame height in pixels (the 14-bit field of the uncompressed chunk).

horizontal_scale: u8

Horizontal upscaling hint (2 bits; 0 = none).

vertical_scale: u8

Vertical upscaling hint (2 bits; 0 = none).

version: u8

Bitstream version (3 bits; selects loop-filter / reconstruction variants).

color_space: u8

Color space (0 = YUV per BT.601; 1 is reserved).

clamp_required: bool

Whether pixel clamping is required (the clamping_type flag).

segmentation: Segmentation

Segmentation state (§9.3).

loop_filter: LoopFilterParams

Loop-filter header (§9.4).

token_partitions: u8

Number of DCT-coefficient token partitions (1, 2, 4, or 8) (§9.5).

quant: QuantIndices

Dequantization indices (§9.6).

refresh_entropy_probs: bool

Whether token-probability updates persist past this frame (§9.11).

mb_no_skip_coeff: bool

Whether macroblocks may signal that they carry no non-zero coefficients (§9.10).

prob_skip_false: u8

Probability that a macroblock is not skipped (only meaningful if mb_no_skip_coeff) (§9.10).

Trait Implementations

impl Clone for Vp8FrameHeader

fn clone(&self) -> Vp8FrameHeader

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for Vp8FrameHeader

impl Debug for Vp8FrameHeader

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

Formats the value using the given formatter.

impl Eq for Vp8FrameHeader

impl PartialEq for Vp8FrameHeader

fn eq(&self, other: &Vp8FrameHeader) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
