Details: The "map" may be different depending on the .wmv file.
run `ffprobe` to see which is the video-track in the .wmv file
usually this is "0.0".
Stream #0.0: Video:...
Stream #0.1: Audio: ..
and "1.0" corresponds to the 2nd input file - your new audio.
You may want to add "-acodec wmav2" and "-ar 128k" options for 128kbit/s
Windows Media Audio 2 or whatever audio-codec/quality your want. `ffmpeg
-codecs | grep "EA"` gives you a list of available codecs for Encoding
BTW. Ardour3 with videotimeline patch can do all this for you.
import,extract,re-encode using ffmpeg.
