StreamCast Installation and Overview

StreamCast allows you to overlay captions onto any application that does not have native captioning support. StreamCast uses a direct feed from StreamText.Net. Simply install StreamCast and position the caption window where you want to display the captions. The window will automatically remain overlain onto your screen and is not affected when you change slides. See the example below.

Currently, there are two Windows versions. will have support for Mac OS and Linux coming very soon. Once installed just click CTRL+s in the StreamCast window. The controls will open, allowing you to configure everything from colors to spacing. 

The new Windows version (recommended) has the controls in the upper left corner. You also need to open the controls to move the window. To move the window, click and hold the Move arrow as you move the window. 

Below are two screenshots, one showing the control cog and the other showing the control window after you click on the cog.

  3. Adjust font size, colors and spacing. Once you have entered all the details, just click the Save Settings button at the bottom of this setup page. The StreamCast window will then appear with your new settings. Once installed it will also remember your last settings so you don’t have to reenter them. (See the settings form below.)
