 +==== Extract Audio from Video and recombine ====
 +(help by Robin Gareus @lau-ml)
 +
 +=== with ffmpeg ===
 +
 +<code>
 +
 +#extract audio
 +ffmpeg -i orig_video.wmv audio_out.wav
 +
 +#replace audio
 +ffmpeg \
 + -i orig_video.wmv \
 + -i new_audio.wav \
 + -vcodec copy \
 + -map 0.0 -map 1.0 \
 + new_video.wmv
 +
 +</code>
 +
 +
 +<code>
 +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
 +Audio.
 +
 +</code>
 +
 +
 +BTW. Ardour3 with videotimeline patch can do all this for you.
 +import,extract,re-encode using ffmpeg.
 +
 +
 +
 +>> Thanks. It is 0:0 and 0:1 and -b:a=192k I found, but I have some sync problems after recombining tho. Any other ideas?
 +
 +My gut feeling is to blame ffmpeg's WMV muxer (it may not be able to mux
 +a bit-exact copy of the original video with your new soundtrack).
 +
 +<code>
 +
 +Try using '-sameq' instead of '-vcodec copy' (re-encode the video with
 +same quality rather than a bit-exact copy - this often solves muxing
 +issues but will cause a small loss of either video quality or increased
 +bandwidth).
 +
 +</code>
 +
 +and also try a different output format eg. 'new_video.avi' or '..mov'
 +instead of 'new_video.wmv'.
 +
 +<code>
 +
 +you may need both, this should work:
 + 'ffmpeg -i vid.wmv -i aud.wav -sameq -map 0.0 -map 1.0 output.avi'
 +
 +</code>
