Generating a Movie File from a List of (JPEG) Images [Custom DataSource]

Problem

Starting from a list of compressed JPEG image files, we'll generate a video-only QuickTime movie of the still images.

Solution

A custom PullBufferDataSource is designed to read compressed JPEG data from a list of JPEG still image files. For each file read, a Buffer object is created and the compressed data is set on the Buffer object.

The custom PullBufferDataSource is then used to create a Processor. The Processor's output is set to generate QuickTime data. The output DataSource of the Processor is then hooked up to a file DataSink to save the bits to a movie file.
