Xvid (formerly XviD) is an open source MPEG-4 video codec, implementing MPEG-4 Simple Profile, Advanced Simple Profile, and Advanced Video Coding standards. It is written in C with assembler optimizations for quality and speed (including MMX, SSE, and 3Dnow! code for i386 and AltiVec for PowerPC), and is especially optimized towards offline, multi-pass compression for storage and archival purposes.
SoX is the Swiss Army knife of sound processing tools: it can convert sound files between many different file formats and audio devices, and can apply many sound effects and transformations, as well as doing basic analysis and providing input to more capable analysis and plotting tools.
docx2txt is a tool that attempts to generate equivalent text files from Microsoft .docx documents, preserving some formatting and document information (which MS text conversion drops) along with appropriate character conversions for a good (ASCII) text experience. It is a platform independent solution consisting of (core) Perl and (wrapper) Unix/Windows shell scripts and a configuration file to control the output text appearance to fair extent. It can very conveniently be used to build a Web based docx document conversion service. Some Makefiles and Windows batch files are provided for easy installation of the scripts. With unzippers like CakeCmd that can deal with corrupt Zip archives, this tool can extract text from corrupt docx documents in many cases, where MS word processor fails to even open them.
MARF is a general cross-platform framework with a collection of algorithms for audio (voice, speech, and sound) and natural language text analysis and recognition, along with sample applications (identification, NLP, etc.) of its use. MARF can run distributed over the network (CORBA, Java RMI, and Java XML-RPC Web Services) and may act as a library in applications or be used as a source for learning and extension.
flac2mp3 is a Perl script to convert FLAC files to MP3 format. It will process an entire directory tree and put the MP3 files in a similar structure. Tags are converted where possible. It will only process a file if the flac file is newer than the MP3 file or if the tags have changed. If just the tags have changed then just the tags are processed, i.e. the file does not have to be transcoded again. flac2mp3 comes bundled with all the non-standard Perl modules required to run. It has been tested on Fedora Core 4 with Perl v5.8.6 and on Windows XP with ActiveState Perl v5.8.7.
WebVCR+ is a Web frontend to record your TV shows from, which has a TV Guide-like interface. You can record your shows to many different formats, and convert them during the idle time your computer isn't recording. You can also add favorites and manage your video library through the Web interface. Listings can be specified in XMLTV format, or grabbed from advalvas/eurotv. You can also easily add different commandline video recorders.
