 So I work with '''avresample''':
 1. Get auto matrix from avresample - ''avresample_build_matrix()''.
 2. Analyzing and modifying the matrix.
 3. Using matrix - ''avresample_set_matrix()''.

 I would like also to work with '''swresample''', but I found only
 ''avresample_set_matrix()'' function, but did not find
 ''swr_build_matrix()''. :(

 Swresample generates a matrix using ''swri_rematrix_init()'' function. I
 want the function to access the resulting matrix.
