ScreenStreamer

Launch ScreenStreamer

Introduction

ScreenStreamer is a tool for transmitting your screen as a video over the Internet. As the screen is transmitted as an RTP stream, this can be recorded using tools that are used to record other RTP streams, such as Arena, another output of the memetic project.

ScreenStreamer is written using Java, and can therefore be run on a variety of platforms. It makes use of the Java Media Framework. This makes it easy to implement new codecs in future versions.

ScreenStreamer can be started from the command line, used as an Access Grid service, or launched via the web using Java Web Start.

Once you are transmitting your screen, users will be able to receive your transmission by either running ScreenStreamer in the same venue as you, or by connecting to your machine using a web browser.

Known Issues

• The H.261 code is very processor intensive. Workaround: Use JPEG as the transmitting format.
• The Screen capture and send code is very processor intensive. Workaround: Ensure that no other processor intenstive code is running on the system.
• Some browsers prompt you to open a php file instead of launching the application. Workaround: Select to open this file with the Java Web Start application (usually javaws or javaws.exe in your java installation directory).
• Sometimes, the receiving computer cannot alter the size of the displayed window. Workaround: Restarting the software eventually alleviates this problem.
• The software does not always work when sending from multi-monitor machines. Workaround: Send from a single monitor machine.
