Struct opencv::gapi::MediaFrame

pub struct MediaFrame { /* private fields */ }

\addtogroup gapi_data_structures

Extra G-API data structures used to pass input/output data to the graph for processing. /

cv::MediaFrame class represents an image/media frame obtained from an external source.

cv::MediaFrame represents image data as specified in cv::MediaFormat. cv::MediaFrame is designed to be a thin wrapper over some external memory of buffer; the class itself provides an uniform interface over such types of memory. cv::MediaFrame wraps data from a camera driver or from a media codec and provides an abstraction layer over this memory to G-API. MediaFrame defines a compact interface to access and manage the underlying data; the implementation is fully defined by the associated Adapter (which is usually user-defined).

Implementations

impl MediaFrame

pub fn default() -> Result<MediaFrame>

Constructs an empty MediaFrame

The constructed object has no any data associated with it.

Trait Implementations

impl Boxed for MediaFrame

unsafe fn from_raw(ptr: *mut c_void) -> Self

Wrap the specified raw pointer

fn into_raw(self) -> *mut c_void

Return an the underlying raw pointer while consuming this wrapper.

fn as_raw(&self) -> *const c_void

Return the underlying raw pointer.

fn as_raw_mut(&mut self) -> *mut c_void

Return the underlying mutable raw pointer

impl Drop for MediaFrame

fn drop(&mut self)

Executes the destructor for this type.

impl MediaFrameTrait for MediaFrame

fn as_raw_mut_MediaFrame(&mut self) -> *mut c_void

impl MediaFrameTraitConst for MediaFrame

fn as_raw_MediaFrame(&self) -> *const c_void

fn desc(&self) -> Result<GFrameDesc>

Returns a media frame descriptor – the information about the media format, dimensions, etc.

fn blob_params(&self) -> Result<any>

@private – exclude from the OpenCV documentation for now.
