Record webcam + sound system

[sebfer]

Hello, I din't find the answer on the forum. Hope i searched enough...

I would like to record the webcam or Ip cam and in the same time the system sound instead of microphone. I didn't found if it is possible. Please, if anyone can help.

The case is simple, my daughter is a dancer and I would like to simply record her while dancing with the music she is dancing on (played from internet, mp3, ... whatever on the laptop) . And sure, the system sound will be better quality than microphone!

Thanks
