[FFmpeg-devel] [PATCH] 8 channel layout fix for Vorbis decoder

The attached patch implements sane channel layout behaviour for 7 and 8
channel Vorbis files.

The Vorbis specification [1] says that the layout for greater than six
channels is left up to the application.  I think the most sensible and
consistent layout for 7 and 8 channels is their 5 and 6 channel
counterparts with back left/right channels appended.
