[PATCH 0/1] opusenc support for WavPack input
This patch to opus-tools adds optional support to WavPack
lossless format as input to opusenc.
Like support to FLAC, it depends on an external library,
libwavpack, and may be disabled on configure.

Channels ordering bug
...ront left
1: front right
2: front center
3: LFE
4: rear left
5: rear right
(source: http://www.microsoft.com/whdc/device/audio/multichaud.mspx#E4C )
Now, in oggenc/audio.c, I see that the permutation array is used that way in
wav_ieee_read:
buffer[j][i] = buf[i*f->channels + f->channel_permute[j]];
To accommodate the specified orders, the permutation array should therefore
be:
0, 2, 1, 4, 5, 3
But wav_permute_matrix defines it as "0,2,1,5,3,4".
The same incorrect array is also present in oggdec.c.
I hope this problem can be fixed.
