This
is an informal presentation about our exploration of two Java
programming techniques for displaying MPEG videos continuously
and frame by frame.
The first technique is an extension of public domain Java source
code for decoding and displaying MPEG video. This approach requires
a good understanding of the MPEG format. Therefore we will provide
a general overview of MPEG parsing, and random access issues,
such as the breakdown of the MPEG video into group of pictures,
and the usage of information within these segments. We will also
look at a sample MPEG decoding program.
The
second technique consists of using the Java Media Framework (JMF)
under development by Sun and Intel. We will describe the applications
of the JMF and the shortcomings of the present implementation.
We will describe how these shortcomings can be circumvented to
provide frame by frame control of MPEG videos.
