Over the years we have seen various patches by folks to enable various 
forms of 6 Channel to Stereo downsampling, non of which ever were 
implemented in the core code base for AAC (internal) processing.

While the solution to this problem can range from a simple mixing of 
channels, adjusting volumes, etc to more advanced, our goal is to find a 
solution acceptable to the ffmpeg team in any form at this point.

Many devices support AAC but in a stereo mode only vs 6 channel, etc.

We would like to offer such a bounty to get such a solution in the code 
base which will enable downsampling of AAC 5.1 to AAC stereo when 
encoding.    An example of two previous variations:


Its important that the solution be acceptable in a form which it can be 
included in the standard code base for ffmpeg so we are not having to 
patch, etc.  Using the internal AAC encoder (-strict experimental)

Depending on the solution we would place the bounty anywhere from $50-$250.

If you are interested in doing this, or do this and looking for payment, 
please email ffmpegbounty [at] bitsling.com

Not sure where best in placing this bounty, so if not on the proper 
list, please let us know as well.

Thank You
