Function Documentation

makeHwVideoBuffer()

std::unique_ptr< QHwVideoBuffer > makeHwVideoBuffer	(	GstSample *	sample,
		const GstVideoInfo &	info,
		QVideoFrameFormat	format,
		const HwVideoBufferContext &	context,
		HwVideoBufferPath &	matchedPath,
		HwResolvedPathCache *	cache = nullptr
	)

Selects the zero-copy QHwVideoBuffer for a GstSample; returns nullptr when no GPU path matches (CPU memcpy fallback).
