Function Documentation

makeHwVideoBuffer()

std::unique_ptr< QHwVideoBuffer > makeHwVideoBuffer	(	GstSample *	sample,
		const GstVideoInfo &	info,
		QVideoFrameFormat	format,
		bool	gpuEnabled,
		void *	eglDisplay,
		void *	ahbEglDisplay,
		HwVideoBufferPath &	matchedPath
	)

Factory that selects the appropriate zero-copy QHwVideoBuffer for a GstSample.

Returns nullptr if no compiled GPU path matches the buffer's memory type, in which case the caller should fall back to the CPU memcpy path. gpuEnabled must be true for any GPU path to be attempted.
