Expand description

Copies src into dst as I4xx (YUV tri-planar).

This function does not change the data layout beyond removing any padding in the source, i.e. both src and dst are 3-planar YUV buffers.

strides and offsets give the stride and starting position of each plane in src. In dst each plane will be put sequentially one after the other.

sub_h and sub_v enable horizontal and vertical sub-sampling, respectively. E.g, if both sub_h and sub_v are true the data will be 4:2:0, if only sub_v is true then it will be 4:2:2, and if both are false then we have 4:4:4.
