Whenever I play a video with multiple audio tracks on vlc the first audio track is played. How do I enable both tracks so that I hear both tracks playing at the same time while playing the video?

    I doubt that is possible, try running two separate instances of vlc.

Launch VLC with the following command line options:

vlc --sout-all --sout #display

All audio tracks in the file will play.

  • I found it superuseful to create a .cmd file with this - start "" "C:\Program Files (x86)\VideoLAN\VLC\vlc.exe" --sout-all --sout #display %1%.. I can now just drag audio+video files on the cmd file and they both play in sync. Idea from the link as well.

If you're running windows, the default player (windows media player) mix all tracks by default, at least on Win8. I don't like WMP and I'm still using VLC but WMP does the job when you need it.

One of the possible ways is to to run multiple instances of VLC. This page from VLC wiki details how this can be done; in a nutshell:

  • Windows: Tools > Preferences... > Interface > playlist and instances:
    • uncheck "Allow only one instance"
    • uncheck "use only one instance when started from file manager"
  • OS X:
    • paste the code below into a new AppleScript Editor script
    • save it as an application

on run
    do shell script "open -n /Applications/VLC.app"
    tell application "VLC" to activate
end run

on open theFiles
    repeat with theFile in theFiles
        do shell script "open -na /Applications/VLC.app " & quote & (POSIX path of theFile) & quote
    end repeat
    tell application "VLC" to activate
end open

  • excuse me for the word but movie maker sucks, I could demux the video file though and combine the tracks. I just want to get it playing at the same time. thanks for the answer though Feb 23 '13 at 10:59

I used James command line options to create a context menu option in windows for my Shadowplay mp4 files. Also I know this is old, but they still don't have a gui option for this for some reason. At least not that I could tell.

Windows Registry Editor Version 5.00

[HKEY_CLASSES_ROOT\VLC.mp4\shell\PlayWithVLCMixAudio]
@="Play with VLC media player with mixed audio tracks"
"Icon"="\"C:\\Program Files\\VideoLAN\\VLC\\vlc.exe\",0"
"MultiSelectModel"="Player"

[HKEY_CLASSES_ROOT\VLC.mp4\shell\PlayWithVLCMixAudio\command]
@="\"C:\\Program Files\\VideoLAN\\VLC\\vlc.exe\" --sout-all --sout #display \"%1%\" --started-from-file --no-playlist-enqueue \"%1\""
