Public Functions Documentation

function QfBarcodeVideoFilter

explicit QfBarcodeVideoFilter::QfBarcodeVideoFilter () 

---

function createFilterRunnable

QVideoFilterRunnable * QfBarcodeVideoFilter::createFilterRunnable () override

---

function decodeVideoFrame

void QfBarcodeVideoFilter::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 QfBarcodeDecoder * QfBarcodeVideoFilter::decoder () const

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

---

function isDecoding

inline bool QfBarcodeVideoFilter::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 QfBarcodeVideoFilter::setDecoder (
    QfBarcodeDecoder * decoder
) 

Sets the decoder to be used when analyzing video frames.
