Hachoir metadata 1.0

Hachoir metadata can extract metadata from archives (bzip2, gzip, zip, tar), audio (MPEG audio/MP3, WAV, Sun/NeXT audio, Ogg/Vorbis, MIDI, AIFF, AIFC, Real Audio), images (BMP, CUR, EMF, ICO, GIF, JPEG, PCX, PNG, TGA, TIFF, WMF, XCF), and video (ASF/WMV, AVI, Matroska, Quicktime, Ogg/Theora, Real Media).
It supports invalid or truncated files and Unicode text. It can remove duplicate values. Hachoir metadata project can also filter metadata according to priority.
Main features:
- Support invalid / truncated files
- Unicode compliant (charset ISO-8859-XX, UTF-8, UTF-16), convert string to your terminal charset
- Remove duplicate values (and if a string is a substring of another, just keep the longest one)
- Set priority to value, so its possible to filter metadata (option --level)
- Only depends on hachoir-parser (and not on libmatroska, libmpeg2, libvorbis, etc.)
Enhancements:
- This release reads the number of channels, bit rate, and sample rate, and computes the compression rate of Real Audio.
- It reads user comments of JPEG pictures.
- It computes the frame rate of Windows ANI.
- It normalizes language for ID3 and MKV.
- OLE2 and FLV extractors are now fault tolerant.
