Although there exists a plethora of programs that count lines of code, I thought I would write my own. It is designed to analyse C/C++ code and ignore whitespace, // and /**/ comments (both the single and multi-line sort). It also counts the number of FIXME's one has left in their code. Other languages (eg: Javascript, assembly) that also use such commenting conventions are compatible too.

I wrote a Windows-based video analysis and processing framework to underpin the research I undertook for my undergraduate thesis.

Some of the features it boasts:

• DirectShow-based: Enables analysis and process of any video/audio format that DShow supports.
• Seeking with frame-accuracy in an MPEG-2 stream: This handy feature I implemented, when used with certain filters, enables frame-accurate seeking (which otherwise is not possible with the standard filter graph (i.e. source filter and demultiplexer).
• Input live streaming TV: I use a Terrestrial Digital Video Broadcasting card to feed Teh Detector live video, which it processes in real-time. It (obviously) also supports offline analysis of stored content.
• Extensible detector architecture: Detectors (analysis components) can be written in C++ and added at will to the framework to extend its capabilities. I implemented several detectors in a hierarchy fashion to find television commercials in a live stream.
• Automatic frame caching: The framework automatically caches video frames and optimises analysis during runtime by also caching various calculations performed on an incoming frame.
• Event store/viewer: Detectors can output 'events' that describe a detected feature in the video, which is automatically stored and managed by the framework. These events can then later be reviewed in an intuitive manner.
• Lots of others: detector timing profiler, signal strength meter, playback rate control, filter graph management, bookmarking, frame dumping, extensive keyboard shortcuts...
