I have a
.wmv with the audio codec of
wmapro, which my target video player chokes on. I am generally in the process to "standardise" my collection to x264/aac (as this works fine on all my devices), but this particular file gave me big trouble. I tried this:
avconv -i input.wmv -c:v libx264 -b:v 4800k -qmin 3 -qmax 69 -ar 44100 \ -b:a 128k -c:a libvo_aacenc -ac 2 -pass 2 -y output.mp4
The first pass worked fine, but now I get the 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
And I googled all morning for this and only found "you got to downmix". I have tried
acs3_fixed and others, all get me this error.
If there is some options I got to give for this to work, I would very much like to know, as I couldn't find them and was not able to figure it out myself.
