Thank you for the sample!
(I wonder how the application is supposed to know which of 
the two "chan" atoms should be used, the one that says 4.0 
or the one that says LRLR? But I did not look carefully.)

FFmpeg currently does not even support reading the channel 
layout, and unfortunately, it is incompatible with the 
internal representation.

Stream-copying should be possible though, afair, I once 
posted a patch that may work.
