Dear all,
I'm happy to announce the release of GNU libextractor 1.0.0.
About GNU libextractor
======================
GNU Libextractor is a simple library used to extract meta data from
files. The goal is to provide developers of file-sharing networks,
browsers or WWW-indexing bots with a universal library to obtain simple
keywords and meta data to match against queries and to show to users
instead of only relying on filenames. GNU libextractor contains the
shell command "extract" that, similar to the well-known file command,
can extract meta data from a file an print the results to stdout.
Currently, GNU libextractor supports the following file formats: HTML,
MAN, PS, DVI, OLE2 (DOC, XLS, PPT), OpenOffice (sxw), StarOffice (sdw),
FLAC, MP3 (ID3v1 and ID3v2), OGG, WAV, S3M (Scream Tracker 3), XM
(eXtended Module), IT (Impulse Tracker), NSF(E) (NES music), SID (C64
music), EXIV2, JPEG, GIF, PNG, TIFF, DEB, RPM, TAR(.GZ), LZH, LHA, RAR,
ZIP, CAB, 7-ZIP, AR, MTREE, PAX, CPIO, ISO9660, SHAR, RAW, XAR FLV,
REAL, RIFF (AVI), MPEG, QT and ASF. Also, various additional MIME types
are detected.
GNU libextractor uses helper-libraries (plugins) to perform the actual
extraction. As a result, GNU libextractor can be extended simply by
installing additional plugins. Writing robust parsers can be difficult.
GNU libextractor protects the main applications from haning or crashing
plugins by executing all plugins out-of-process.
GNU libextractor is written in C. However, a binding for Java exists.
Noteworthy improvements in 1.0.0
================================
* All plugins run out-of-process, in parallel, with full random access
to the entire input data
* Major rewrite of most plugins, now frequently using standard parser
libraries to access standard file formats
* New plugin based on GStreamer supports many multi-media formats
* Good testcase coverage of the main library and plugins
* Tested on GNU/Linux, FreeBSD, OS X and W32 systems
* API-compatible with GNU libextractor 0.6.x
Availability
============
The GNU libextractor source code is available from all GNU FTP mirrors.
The Java binding is a separate download.
