Enum VideoAccelerationType 

#[repr(i32)]
pub enum VideoAccelerationType {
    VIDEO_ACCELERATION_NONE = 0,
    VIDEO_ACCELERATION_ANY = 1,
    VIDEO_ACCELERATION_D3D11 = 2,
    VIDEO_ACCELERATION_VAAPI = 3,

}

Video Acceleration type

Used as value in CAP_PROP_HW_ACCELERATION and VIDEOWRITER_PROP_HW_ACCELERATION

Note: In case of FFmpeg backend, it translated to enum AVHWDeviceType (https://github.com/FFmpeg/FFmpeg/blob/master/libavutil/hwcontext.h)

Variants

VIDEO_ACCELERATION_NONE = 0

Do not require any specific H/W acceleration, prefer software processing. Reading of this value means that special H/W accelerated handling is not added or not detected by OpenCV.

VIDEO_ACCELERATION_ANY = 1

Prefer to use H/W acceleration. If no one supported, then fallback to software processing.

Note: H/W acceleration may require special configuration of used environment.

Note: Results in encoding scenario may differ between software and hardware accelerated encoders.

VIDEO_ACCELERATION_D3D11 = 2

DirectX 11

VIDEO_ACCELERATION_VAAPI = 3

VAAPI

VIDEO_ACCELERATION_MFX = 4

libmfx (Intel MediaSDK/oneVPL)

Trait Implementations

impl Clone for VideoAccelerationType

fn clone(&self) -> VideoAccelerationType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for VideoAccelerationType

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

Formats the value using the given formatter.

impl From<VideoAccelerationType> for i32

fn from(v: VideoAccelerationType) -> Self

Converts to this type from the input type.

impl PartialEq for VideoAccelerationType

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

impl TryFrom<i32> for VideoAccelerationType

type Error = Error

The type returned in the event of a conversion error.

fn try_from(value: i32) -> Result<Self, Self::Error>

Performs the conversion.

impl Copy for VideoAccelerationType
