[FFmpeg-devel] [PATCH]Add 7.1 wide back channel layout name

[Carl Eugen Hoyos]

Hi!

Currently, typical 8 channel aac files are shown as "8 channels 
(FL+FR+FC+LFE+BL+BR+FLC+FRC)" instead of "7.1(wide)", this is a regression 
since 0.11.

Attached patch intends to fix this, please comment.

I am not completely convinced that "7.1(wide-side)" exists in the wild.
