[PATCH] Support for Channel Mapping 253.
...DEX macro, multiplication may overflow if int is 16 bits.
One of the operands of the multiplication should be cast to opus_int32
in such cases to ensure a 32-bit multiply and avoid overflow.
4) get_multistream_decoder: align() must be applied separately to
sizeof(OpusProjectionDecoder) and st->demixing_matrix_size_in_bytes
since they may each have padding. Including the alignment padding in
demixing_matrix_size_in_bytes as in (5) avoids the second call to
align(). Similarly in opus_projection_decoder_get_size, align()
should just be applied to sizeof(OpusProjectionDecoder); in that case
the other sizes may...

Actually, I don't see what your encoder change is supposed to do. Are
there cases where demixing_matrix->rows != nb_output_streams ?
