How to Use Video on One Computer & Audio on Another in Ustream

Use one computer for video processing and another for audio.

Ustream is an online video service that allows people to create and transmit live broadcasts of themselves that include video and audio. Transmitting video and audio over the Web requires the allocation of computational resources on your computer, which may cause problems, such as overheating or choppy video. This is common when you are performing complex tasks on-the-fly like adding real-time effects to your broadcast. If your computer is having trouble processing and transmitting your broadcast, use one computer to process the video and another for the audio.

Things You'll Need

• Stereo mini-jack cable

Instructions

1. Connect one end of your stereo mini-jack cable to the headphones output of the computer that is processing your audio.

2. Connect the other end of the stereo mini-jack cable to the audio line-in input on the computer that is processing your video.

3. Log into your Ustream account using the computer that is processing your video. Click "Start Broadcasting". Name your broadcast. Click "Create".

4. Click "Allow" in the Adobe Flash Player Settings window that appears.

5. Select "Line-in" as the "Audio Source" in Ustream. If the audio is not transmitting to Ustream or "Line-in" is not an option, right-click (Windows) or control-click (Mac) on the Ustream window. Select "Settings" from the menu. Click the microphone icon in the Adobe Flash Player Settings window. Select "Built-in Input" under "Microphone." Click "Close".

Tips & Warnings

• Use a short stereo mini-jack cable to avoid degrading the quality of your audio. Set the "Audio Quality" in Ustream at or below 22 kilohertz to avoid slowing down your transmission.

• If your live broadcast is choppy or lagging, decrease the "Video Quality" and "Audio Quality" of your broadcast in Ustream.
