I have a 5.1 audio track from a film where front left and front right contains music, and center contains dialogue. Playing the 5.1 track in VLC blends everything together nicely.
I'm trying to convert the 5.1 track to stereo using
ffmpeg -ac 2, however the resulting stereo mix has a much weaker volume than playing the 5.1 track natively.
-af "pan=stereo|c0=FL|c1=FR" gives the correct volume, but then there is no dialogue because the center channel is not included.
So the solution is maybe to mix left/center/right into stereo, and throw out the back end subwoofer channels? (I'm guessing here...)
So the question is: How do I make ffmpeg downmix 5.1 to stereo the same way VLC does it, with the same strong volume in the end result?
