Trying to Stream from RCA Inputs

[GregBrunton]

Hi All,

In major need of someones expertise.
My area of IT is software orientated so I am a little out of my depth here.

I am getting output from a video switcher in the form of an RCA cable. This cable contains both Audio and Video.
This cable will be feeding live footage to be streamed.
I will be streaming this footage through a laptop using software that I have.
Originally I bought an RCA to HDMI converter as I had thought that because it was originally coming from an RCA cable that a video capture device was not neccessary, I now see that is wrong.

So my question is this. How do I get this out from from RCA into my computer so that I may directly stream what is coming through the feed.
Would a simple RCA to USB converter work? Or do I need something else? If so what?

NEEDING MAJOR HELP

Thanking all

So I think this is a composite cable yellow, red and white? Since you are using a laptop, you need to have a device that accepts rca and would connect to usb like yes a usb video capture device. So the video/audio goes through the rca cables to usb in your laptop and you can either view or stream it like with windows media encoder.
