Fields

emulated_edge_mc: Option<unsafe extern "C" fn(dst: *mut u8, src: *const u8, dst_linesize: isize, src_linesize: isize, block_w: c_int, block_h: c_int, src_x: c_int, src_y: c_int, w: c_int, h: c_int)>

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

@param dst destination buffer @param dst_stride number of bytes between 2 vertically adjacent samples in destination buffer @param src source buffer @param dst_linesize number of bytes between 2 vertically adjacent samples in the destination buffer @param src_linesize number of bytes between 2 vertically adjacent samples in both the source buffer @param block_w width of block @param block_h height of block @param src_x x coordinate of the top left sample of the block in the source buffer @param src_y y coordinate of the top left sample of the block in the source buffer @param w width of the source buffer @param h height of the source buffer

prefetch: Option<unsafe extern "C" fn(buf: *mut u8, stride: isize, h: c_int)>

Prefetch memory into cache (if supported by hardware).

@param buf pointer to buffer to prefetch memory from @param stride distance between two lines of buf (in bytes) @param h number of lines to prefetch
