Struct providing information about video file format. :

Fields

codec: CUDA_Codec

chroma_format: CUDA_ChromaFormat

surface_format: CUDA_SurfaceFormat

Surface format of the decoded frame.

n_bit_depth_minus8: i32

n_bit_depth_chroma_minus8: i32

ul_width: i32

Coded sequence width in pixels.

ul_height: i32

Coded sequence height in pixels.

width: i32

Width of the decoded frame returned by nextFrame(frame).

height: i32

Height of the decoded frame returned by nextFrame(frame).

ul_max_width: i32

ul_max_height: i32

display_area: Rect

ROI inside the decoded frame returned by nextFrame(frame), containing the useable video frame.

valid: bool

fps: f64

ul_num_decode_surfaces: i32

Maximum number of internal decode surfaces.

deinterlace_mode: CUDA_DeinterlaceMode

target_sz: Size

Post-processed size of the output frame.

src_roi: Rect

Region of interest decoded from video source.

target_roi: Rect

Region of interest in the output frame containing the decoded frame.

video_full_range_flag: bool

Output value indicating if the black level, luma and chroma of the source are represented using the full or limited range (AKA TV or “analogue” range) of values as defined in Annex E of the ITU-T Specification.

color_space_standard: CUDA_ColorSpaceStandard

Video Signal Description Color Primaries of the VideoReader source (section E.2.1 VUI parameters semantics of H265 spec file)

enable_histogram: bool

Flag requesting histogram output if supported. Exception will be thrown when requested but not supported.

n_counter_bit_depth: i32

Bit depth of histogram bins if histogram output is requested and supported.

n_max_histogram_bins: i32

Max number of histogram bins if histogram output is requested and supported.

Implementations

impl CUDA_FormatInfo

pub fn default() -> Result<CUDA_FormatInfo>

Trait Implementations

impl Clone for CUDA_FormatInfo

fn clone(&self) -> CUDA_FormatInfo

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for CUDA_FormatInfo

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

Formats the value using the given formatter.

impl PartialEq for CUDA_FormatInfo

fn eq(&self, other: &CUDA_FormatInfo) -> 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.
