SwsComps SwsOp::comps

Metadata about the operation's input/output components.

For SWS_OP_READ, this is informative; and lets the optimizer know additional information about the value range and/or pixel data to expect. The default value of {0} is safe to pass in the case that no additional information is known.

For every other operation, this metadata is discarded and regenerated automatically by ff_sws_op_list_update_comps().

Note that backends may rely on the presence and accuracy of this metadata for all operations, during ff_sws_ops_compile().
