audio - Avconv: Select german stream not highest quality ...
https://stackoverflow.com/questions/15738239/avconv-select-german-stream-not-highest-quality-one
The following worked in my case (I wanted to chose a lower-resolution stereo stream that had better channel separation instead of the higher-resolution 5.1 stream that didn't merge down as well). In your case, the (ger) stream you want is "0.2", except avconv wants a colon separator, e.g. avconv -i input.m4v -map 0:2 output.mp3

avconv: remove audio stream, keep audio and video ...
https://unix.stackexchange.com/questions/202135/avconv-remove-audio-stream-keep-audio-and-video-synchronized
I would like to discard two of the audio streams, keeping only one. I tried to do so using avconv (v11.3-6): avconv -i in.avi -map 0:0 -map 0:2 -vcodec copy -acodec copy out.avi. The problem is that in the resulting file the remaining audio stream is no longer correctly synced to the video stream, though they are synced in the original.
