Enum opencv::videoio::VideoAccelerationType

#[repr(C)]
pub enum VideoAccelerationType {
    VIDEO_ACCELERATION_NONE,
    VIDEO_ACCELERATION_ANY,
    VIDEO_ACCELERATION_D3D11,
    VIDEO_ACCELERATION_VAAPI,
    VIDEO_ACCELERATION_MFX,
}

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

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

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

DirectX 11

VIDEO_ACCELERATION_VAAPI

VAAPI

VIDEO_ACCELERATION_MFX

libmfx (Intel MediaSDK/oneVPL)
