I'm getting a message, that it cannot resample 6 channels into 2 channel audio. This is the command i'm using to convert into h.264+aac:
avconv -i /var/movies/Some.movie.2010.BDRip.XviD.AC3.-HQ-ViDEO.avi -strict experimental -acodec aac -ac 2 -ab 128k -ar 44100 -y -c:v libx264 -qscale 1 -s 640x480 -g 25 -r 25 /path/to
Exact message:
Resampling output channel count must be 1 or 2 for mono input; 1, 2 or 6 for stereo input; or N for N channel input.
Can not resample 6 channels @ 48000 Hz to 2 channels @ 44100 Hz
I have tried so many configurations, have tired experimenting.
Any video guru out there? Some tip would be awesome.
Thanks.
Here is avconv info:

The error message indicates "or N for N channel input.", which suggests that if you have 6 input channels, you can only resample to 6 output channels. Maybe you need a different operation to downsample? – Darth Android – 2013-05-20T15:53:08.880
What options do i have in this situation? – Somebody – 2013-05-20T16:07:56.520
This suggests that downmixing in this fashion should work, all else being equal. Possibly a dumb question, but: have you tried first downsampling from 48KHz to 44.1KHz, and then downmixing to stereo from there? – Aaron Miller – 2013-05-20T16:55:38.097
