void(* VideoDSPContext::emulated_edge_mc) (uint8_t *buf, const uint8_t *src, ptrdiff_t linesize, int block_w, int block_h, int src_x, int src_y, int w, int h)

Copy a rectangular area of samples to a temporary buffer and replicate the border samples.

Parameters

buf	destination buffer
src	source buffer
linesize	number of bytes between 2 vertically adjacent samples in both the source and destination buffers
block_w	width of block
block_h	height of block
src_x	x coordinate of the top left sample of the block in the source buffer
src_y	y coordinate of the top left sample of the block in the source buffer
w	width of the source buffer
h	height of the source buffer
