[Carl Eugen Hoyos]

ffmpeg | branch: master | Carl Eugen Hoyos <cehoyos at ag.or.at> | Fri May 13 00:22:05 2011 +0200| [0aac0403c54eb7f47d5d707e1368e52763043a69] | committer: Carl Eugen Hoyos

Map mlp surround channels to FFmpeg rear channels.

This allows more 3rd party applications to correctly read
the resulting wav files.
