int	width_align
int	width_pad
int	plane_copy [4]
	Map of planes which are directly copied from the pass input.

Detailed Description

Represents an output buffer for a filter pass.

During filter graph construction, these merely hold the metadata. Allocation of the underlying storage is deferred until after all filter passes are settled.

plane_copy

int SwsPassBuffer::plane_copy[4]

Map of planes which are directly copied from the pass input.

These may be promoted from a memcpy to a refcopy.

Each entry maps the output index to the corresponding input plane index, or -1 for no copythrough.
