◆ hw_frames_ref

AVBufferRef* SwsGraph::hw_frames_ref

Definition at line 140 of file graph.h.

◆ plane_copy

int SwsGraph::plane_copy[4]

Map of planes which directly copied from the input.

These may be promoted from a memcpy to a refcopy. This requires special handling by the caller.

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