[PATCH] support 7 and 8 channel wav files as input
Now that we've selected a channel mapping for 7 and 8 channel flac, the
command-line encoder tools needs updating to accept wav files with
compatible channel maps.

[PATCH] for flac/decode.c
The commit http://git.xiph.org/?p=flac.git;a=commitdiff;h=99257e177eac96fa41a107b423080232f59ebe45
also requires some changes in write_iff_headers() function:
currently flac don't write WAVEFORMATEXTENSIBLE header if
decoder_session->channel_mask is equal to 0, 1 or 3.
After the commit 99257e17 flac should do this for channel_mask
equal to 0, 4 or 3.
The patch fixes this.
--------------------------
Also, I have a question.
Currently flac complains about 24-bit .wav files if they have
old WAVEFORMATEX header and not 'proper' WAV...

PATCH: WAVEFORMATEXTENSIBLE_CHANNEL_MASK is ignored when decoding
Currently FLAC doesn't read the contents of
WAVEFORMATEXTENSIBLE_CHANNEL_MASK tag in a decoded FLAC file and doesn't
write correct channel mask to a WAV file.
(d->channel_mask == 0 inside DecoderSession_process() function in decode.c)
The attached patch fixes this problem but I'm not sure that
it doesn't have any side effects... Also, maybe it's better to...

But this text describes only those 4 bits in frame header.
IMHO this sectoin should not describe WAVEFORMATEXTENSIBLE_CHANNEL_MASK,
it should be described somewhere in vorbis comments section.

Your proposed wording was:
0000-0111 : (number of independent channels)-1. The channel order
follows SMPTE/ITU-R recommendations. The assignments are as follows:
