score::gfx::PixelFormatInfo Struct Reference

Detailed Description

Describes the pixel layout properties relevant for GPU decoding. Extracted from AVPixFmtDescriptor / codec parameters.

Public Member Functions
bool	is10bit () const noexcept

Static Public Member Functions
static PixelFormatInfo	fromAVPixelFormat (AVPixelFormat fmt)
	Build from an AVPixelFormat.
static PixelFormatInfo	fromCodecParameters (AVPixelFormat swFormat, AVPixelFormat codecparFormat, int bitsPerRawSample)

Public Attributes
int	log2ChromaW {1}
	Horizontal chroma subsampling: 0=4:4:4, 1=4:2:2/4:2:0.
int	log2ChromaH {1}
	Vertical chroma subsampling: 0=4:4:4/4:2:2, 1=4:2:0.
int	bitDepth {8}
	Per-component bit depth (8, 10, 12, 16)
int	numPlanes {2}
	Number of planes (2 for semi-planar, 3+ for planar)
bool	hasAlpha {}
	Format includes an alpha channel.

static PixelFormatInfo score::gfx::PixelFormatInfo::fromCodecParameters ( AVPixelFormat  swFormat, AVPixelFormat  codecparFormat, int  bitsPerRawSample  )

inlinestatic

Build from codec parameters, with optional sw_format override. bits_per_raw_sample from the codec is used as a hint when > 8.
