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
