kdu_compressed_video_source

This abstract base class defines core services of interest to applications working with compressed video content. Itself derived from kdu_compressed_source, implementations of this class may be passed to kdu_codestream::create, for the purpose of parsing and/or decompressing individual images from a compressed video source.

Kakadu's implementation of the Motion JPEG2000 file format offers an appropriately derived class ( mj2_video_source), which implements the interfaces declared here. For a much simpler implementation, or inspiration for implementing your own video source classes, you might consider the kdu_simple_video_source class.
