avidentify is a command line tool that extracts and prints various meta-information about media files: width, height, frame rate, video codec, audio codec, audio sample rate, audio bitrate, file format, etc. It uses ffmpeg's libavformat library to read the video files, thus MPEG, AVI, WMV, MP3, Ogg, and many other file formats are supported. avidentify is similar to MPlayer's midentify tool, but it has far fewer dependencies.
h300goodies consists of a handful of Perl and shell scripts that were written to help manage a user's music collection on an iRiver H320 or H340 digital jukebox. These scripts don't run on the player natively, but are used when the player is mounted on a local file system via a USB connector. The scripts will build M3U playlists that you define, scan your collection and build playlists based on the genre in the MP3/Ogg file ID3 tags, scan your collection for long filenames that cause problems with iRiver's database software, randomize an existing M3U playlist, and so on.
