VideoAccelerationType enum
@brief 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)
Values
- VIDEO_ACCELERATION_NONE → const VideoAccelerationType
-
!< 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.
const VideoAccelerationType(0) - VIDEO_ACCELERATION_ANY → const VideoAccelerationType
-
!< 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.
const VideoAccelerationType(1) - VIDEO_ACCELERATION_D3D11 → const VideoAccelerationType
-
!< DirectX 11
const VideoAccelerationType(2) - VIDEO_ACCELERATION_VAAPI → const VideoAccelerationType
-
!< VAAPI
const VideoAccelerationType(3) - VIDEO_ACCELERATION_MFX → const VideoAccelerationType
-
!< libmfx (Intel MediaSDK/oneVPL)
const VideoAccelerationType(4)
