Detailed Description

Module for extracting frames from DeckLink Video cards.

Reads Video frames and processes them into a OpenCV friendly format. The results are later used in the ImageImport class.

Notes

This should provide nothing more or less than the ability to control video devices, including but not limited by input source selection, initialization, format settings, and frame grab selection.

Creates a DeckLinkImport object

Member Function Documentation

int DeckLinkImport::grabFrame

(

cv::Mat *

frame

)

Instantaneously retrieves a frame from the video stream in OpenCV format.

Parameters

frame

Allocated OpenCV frame (Mat) to dump the frame data into.

Returns

Status indicating whether the operation was successful or not.

virtual Frame* DeckLinkImport::next_frame ( )

virtual

Retrieves a frame from the processing queue in OpenCV format.

Returns

A frame from the video for further usage in further computations and analysis.

Implements ImageImport.

int DeckLinkImport::startCapture

(

)

Begins capture. Creates a video stream which a frame may be grabbed from.

Returns

Status indicating whether the operation was successful or not.

int DeckLinkImport::stopCapture

(

)

Stops capture and releases the device for use by other software.

Returns

Status indicating whether the operation was successful or not.
