Hi

I like VLC al lot using it since ... dunno forever ...

I´d really like to make full use of the new improved media library - But i have to YES have to ... Use Winamp for Webradio (because of shoutcast to be fair) and MediaMonkey for my mp3´s

So ... Why ?

THERE IS NO STEREO TO SURROUND UPMIXER !


Nearly everybody who i know owns a at least 5.1Soundsystem ... So this is like a BASIC feature ... hello we are in 2010 ... FUTURE and such ...

You wouldnt have to reinvent the fukking wheel ...

http://sourceforge.net/projects/winampmatrixmix/files/

There is a Winampplugin i use for upmixing stereo to 5.1 its based on ac3filter - its free .. the source is there ... Plug and play ...


Sry but this is a feature that has to be in a modern media player ... dunno why this isn´t build in vlc for like 6 years or so ...

The algorithm code would be quite easy to add, but it would require some additional GUI panels since there isn't any right way to do stereo -> 5.1 upmixing (some people would want less surround and others etc.).

Well i'm willing to give it a shot, as in to write the code but i'm not very failure with the back-end.
vlc_help you state it should be easy, want to give me a heads up as to where i should look.
I'm also looking at phonon-vlc backend.

that would be good place to start.
