Function Documentation

◆ applyColorimetry()

void applyColorimetry	(	QVideoFrameFormat &	format,
		const GstVideoInfo &	info,
		GstCaps *	caps
	)

Set color-space/transfer/range from gst-video colorimetry + HDR (MaxCLL preferred); infers BT.601/709 from height when caps omit it.

◆ applyCropMeta()

QVideoFrameFormat applyCropMeta	(	QVideoFrameFormat	format,
		GstBuffer *	buffer
	)

Apply video crop meta to format's viewport. Pass-through when no crop meta present.

◆ applyOrientationAndTiming()

void applyOrientationAndTiming	(	QVideoFrame &	frame,
		GstBuffer *	buffer,
		int	streamOrientation
	)

Per-frame orientation (meta wins, else stream fallback) + PTS/duration timing; streamOrientation is GstVideoOrientationMethod cast to int.
