[MEncoder-users] Correct routing of AC3 5.1 -> AAC 5.1 during encoding

[Grozdan Nikolov]

Hi,

I'd like to encode the audio of a DVD from AC3 5.1 to AAC 5.1 but I don't know 
how to set up the correct routing so I can obtain the same channels position 
in the AAC audio. When I only use the -channels 6 parameter during the 
encoding, the channels in the AAC audio do not have the same position as the 
original AC3 audio. To my understanding, I'll have to use the -af channels 
filter but I don't get it how it works and how to set up the correct routing 
so I can get the same channels position in the AAC audio. Can someone provide 
me the -af channels option that I have to use in order to achieve this?

Thanks in advance
