PyDaF stands for Python Data Flows. It is an experimental Python package that implements data-driven processing pipelines, which revolve around two major elements: data units, which encapsulate a type, a set of tags and actual data, and processors (fragments of code that get executed whenever the job's current data pool contains data units matching the processor's input specification).
SQL Tagger reads the tags of audio files from a directory, loads them into a temporary SQLite database, accepts SQL queries to modify this database, then saves any changes back to the audio files. It's useful for performing complex updates that would be difficult or tedious with conventional taggers. It's a complement to conventional taggers, not a replacement.
MythRip is a GUI for exporting recordings from MythTV. It offers a full-featured, re-orderable, multi-threaded encoding queue, support for x264 video and two-pass encoding, encoder presets, the ability to delete recordings from MythTV, the ability to preview recordings from MythTV, template-based output filenames, and more. MythRip is a GUI alternative to nuvexport. It requires mencoder to encode and mplayer to preview videos.
