Several tools are described that analyze the encoding of video streams compressed
according to the MPEG-1 standard. The relative strengths and weaknesses of each
tool are discussed, along with the problems solved in implementing them. Finally,
several statistics-gathering extensions to the Continuous Media Toolkit (CMT)
are introduced. These extensions provide a powerful, highly configurable, and
conceptually simple framework for the design of customized MPEG-1 analysis tools.
