Struct FrameHeader 

#[non_exhaustive]
pub struct FrameHeader {
    pub width: u32,
    pub height: u32,
    pub pixel_format: PixelFormat,
    pub presentation_timestamp: Option<i64>,
}

Per-frame metadata carried alongside an Arena inside a Frame. Kept minimal in round 1; round 2 will extend with stride/colorspace/HDR fields as decoders need them.

Copy so it travels through the hot path with no allocation.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

width: u32

height: u32

pixel_format: PixelFormat

presentation_timestamp: Option<i64>

Presentation timestamp in stream time-base units. None when the codec did not surface one (e.g. a still image).

Implementations

impl FrameHeader

pub fn new( width: u32, height: u32, pixel_format: PixelFormat, presentation_timestamp: Option<i64>, ) -> Self

Construct a header with all four mandatory fields set. Use functional-update syntax (FrameHeader { ..header }) to add future fields safely.
