Expand description

Platform-neutral metadata carried identically by CPU and hardware frames.

It says nothing of the memory behind the picture: a hardware surface may be larger than its frame (a 1080p H.264 surface is 1088 rows), by an amount each platform decides, and an importer reports the extent it samples itself.

Fields§

§pts: MediaTime

Presentation timestamp.

§dts: Option<MediaTime>

Decode timestamp when available.

§duration: Option<MediaTime>

Nominal duration when available.

§visible_rect: Rect

Visible crop.

§orientation: Orientation

How the picture is shown upright.

§sample_aspect_ratio: SampleAspectRatio

Pixel aspect ratio.

§color: Option<ColorMetadata>

Color declaration.

§chroma_location: ChromaLocation

Chroma sample position.

§bit_depth: u8

Significant component bits.

§plane_layout: NativePlaneLayout

Memory plane organization.

§device_identity: u64

GPU device identity, zero for CPU frames.

§decoder_generation: u64

Decoder or surface-pool generation.

§picture_identity: u64

Physical picture identity within the generation.
