It is not. --disable-dct refers to the 1D DCT based on the FFT. The rest of the dct options are for 8x8 2D DCTs used in video codecs. Other than being based on the same mathematical principles, they have nothing in common. -- Måns Rullgård [email protected] _______________________________________________ libav-devel mailing list [email protected] https://lists.libav.org/mailman/listinfo/libav-devel
