In order to capture live video from any of those outputs, you need to have a capturing device, or a peripheral connected to your encoding machine.You could do that via USB 3.0, IEEE 1394, Thunderbolt, HDMI or other method.If your web camera didn't come with a software disc, simply plug it in and see what happens.
Your camera records the action, but not in a format that works well for transmitting over the internet.
The software and hardware requirements for producing a live webcast of an event are the following: Most professional HD cameras have a number of outputs - HDMI, SDI, HD-SDI, etc.
Older models also have an IEEE 1394 (also known as i Link, or Fire Wire) connector.
Figure: Thunderbolt, IEEE 1394, HDMI, HD-SDI, USB 3 Here are a few devices you could use as peripherals, that could capture live video feed from your camera, and make it available to the encoding/streaming machine: After having decided how you will input a live video feed to your streaming machine, you have to pick a live encoding software.
Alternatively you could also use a hardware live encoder, but for the purpose of this post, we will review the software ones: Adobe Flash Media Live Encoder - a free live encoding software product from Adobe, currently available for MS Windows and Mac OS X.
