Function Documentation

ff_sws_lut3d_alloc()

SwsLut3D * ff_sws_lut3d_alloc

(

void

)

Allocates a refstruct.

Note that the LUT contents are not initialized.

ff_sws_lut3d_generate()

int ff_sws_lut3d_generate	(	SwsLut3D *	lut3d,
		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 ff_sws_lut3d_update().

Returns 0 or a negative error code.

ff_sws_lut3d_update()

void ff_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.

ff_sws_lut3d_apply_rgba64()

void ff_sws_lut3d_apply_rgba64	(	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 in RGBA64 format.
