  1. 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.

    I'm using:
    avconv version 0.8.6-4:0.8.6-0ubuntu0.12.04.1, Copyright (c) 2000-2013 the Libav developers
    built on Apr 2 2013 17:02:36 with gcc 4.6.3

  2. -> http://www.ffmpeg.org/ffmpeg-filters.html#Mixing-examples should be able to do the job,...
    (personally I use sox for downmixing -> http://forum.doom9.org/showthread.php?t=152034 and from the looks of it one can probably 'translate' the sox calls I use into ffmpeg calls)

  5. Did you use the code from the example or did you adjust it to another downmix?
