Creating a Multimedia Extension for Tcl Using the Java Media Framework

Abstract
As multimedia capable computers become cheaper and more pervasive in
the consumer and corporate markets, and as the availability of digital
information increases, the need for low-cost, cross-platform multimedia
applications will steadily rise. However, because Tcl lacks native support
for continuous media streams, such as audio, video, and animation, it is
not well suited for this emerging application domain. At the same time,
Java now provides a set of class libraries, called the Java Media Framework
(JMF), which provides the multimedia support that Tcl lacks. With the recently
introduced integration of Tcl and Java, Java can now be used to provide
the cross-platform multimedia support required by Tcl; whereas Tcl can
be used to provide the easy-to-use programming environment required for
building multimedia applications. In this paper, we introduce a Tcl extension
that provides a high-level scripting interface to the Java Media Framework.
In addition, we will highlight some interesting problems in the current
Tcl/Java package as well as suggest some potential solutions. This paper
will benefit Tcl programmers who would like to learn more about using Tcl
to build multimedia applications, integrating Tcl and Java, or the multimedia
support provided by the JMF.
