sws_lut3d_test_fmt()

bool sws_lut3d_test_fmt	(	enum AVPixelFormat	fmt,

Test to see if a given format is supported by the 3DLUT input/output code.

sws_lut3d_pick_pixfmt()

enum AVPixelFormat sws_lut3d_pick_pixfmt	(	SwsFormat	fmt,
		int	output
	)

Pick the best compatible pixfmt for a given SwsFormat.

sws_lut3d_generate()

int sws_lut3d_generate	(	SwsLut3D *	lut3d,
		enum AVPixelFormat	fmt_in,
		enum AVPixelFormat	fmt_out,
		const SwsColorMap *	map
	)

Recalculate the (static) 3DLUT state with new settings.

This will recompute everything. To only update per-frame tone mapping state, instead call sws_lut3d_update().

Returns 0 or a negative error code.

sws_lut3d_update()

void sws_lut3d_update	(	SwsLut3D *	lut3d,
		const SwsColor *	new_src
	)

Update the tone mapping state.

This will only use per-frame metadata. The static metadata is ignored.

sws_lut3d_apply()

void sws_lut3d_apply	(	const SwsLut3D *	lut3d,
		const uint8_t *	in,
		int	in_stride,
		uint8_t *	out,
		int	out_stride,
		int	w,
		int	h
	)

Applies a color transformation to a plane.

The format must match the format provided during sws_lut3d_update().
