This is not how it should be done. The coefficients should be exported so that downmixing can be done at the user level using libavresample. Alternatively, downmixing could be done in the decoder only if it is done in a way that speeds up decoding, like doing it prior to the IMDCT. -Justin _______________________________________________ libav-devel mailing list [email protected] https://lists.libav.org/mailman/listinfo/libav-devel
