I want to develop a online karaoke site where users can select a video

I want to develop a online karaoke site where users can select a video and start recording their voice.
Short flow chart will be like this.

Select Karaoke Video(source video) ->
New Page with Source Video and User’s Webcam and Audio ->
Click recording will start Source video and start recording user’s audio while playing source video.

When Source Video end, user’s voice and source video are combined on the server and generate a recorded karaoke song.

By the way, karaoke songs are preloaded with only background and harmony.

So everything are server side.
Anyone can advice commercial or free software for my project? Thanks

    Specification of your server OS would have been nice.
    I can recommend AviSynth. It is a command line/script driven non-linear video editing application. Quite a learning curve, but if you master it, it can do anything (concerning audio&video 😉 ) for you.
    Unfortunately, they have big problems with their site at the moment. You can find Information about it on
    http://avisynth.org/mediawiki/Main_Page
    and there are some articles on doom9.org.

    There is also good old ffmepg, which is available for some OSes and can do some things via commandline (not as powerful as AvySynth, but enough for simple muxing.

    Also VirtualDub can be scripted. I did never use it without the GUI, but should do the same thing.

    Last but not least gstreamer, very powerful, hard to hack.

    Me guess would be, you think its only simple muxing and will find out soon, that you need much more for your purpose :-). Synchronicity of A\V can quickly become a problem here.

    For linux systems also take a look at mencoder (closely tied to mplayer). There is a command line version available. As one smart guy said: THE swiss army knife for A\V-stuff.
