Public Properties Documentation

property decoder [1/2]

BarcodeDecoder * BarcodeVideoFilter::decoder;

Public Signals Documentation

signal decoderChanged

void BarcodeVideoFilter::decoderChanged;

Public Functions Documentation

function BarcodeVideoFilter

explicit BarcodeVideoFilter::BarcodeVideoFilter ()

function createFilterRunnable

QVideoFilterRunnable * BarcodeVideoFilter::createFilterRunnable () override

function decodeVideoFrame

void BarcodeVideoFilter::decodeVideoFrame (
    QVideoFrame * input
)

Handle the decoding of a video frame barcodes. The frame will be analyzed for the presence of a barcode, and if so the decoder will capture the decoded string.

function decoder [2/2]

inline BarcodeDecoder * BarcodeVideoFilter::decoder () const

Returns the barcode decoder to be used when analyzing video frames.

function isDecoding

inline bool BarcodeVideoFilter::isDecoding () const

Returns whether a video frame decoding is happening, which will dictate whether incoming video frames will be skipped or not.

function setDecoder

void BarcodeVideoFilter::setDecoder (
    BarcodeDecoder * decoder
)

Sets the decoder to be used when analyzing video frames.
