hachoir-metadata extracts metadata from multimedia files: music, picture, video, but also archives. It supports most common file formats: * Archives: bzip2, gzip, zip, tar * Audio: MPEG audio ("MP3"), WAV, Sun/NeXT audio, Ogg/Vorbis (OGG), MIDI, AIFF, AIFC, Real audio (RA) * Image: BMP, CUR, EMF, ICO, GIF, JPEG, PCX, PNG, TGA, TIFF, WMF, XCF * Video: ASF format (WMV video), AVI, Matroska (MKV), Quicktime (MOV), Ogg/Theora, Real media (RM) . It tries to give the more informations as possible. For some file formats, it gives really more informations then libextractor for example. RIFF parser is really good for example, it can extract creation date, software used to generate the file, etc. But hachoir-metadata can not guess informations. The most complex operation is just to compute duration of a music using frame size and file size. . hachoir-metadata has three modes: * classic mode: extract metadata, you can use --level=LEVEL to limit quantity of information to display (and not to extract) * --type: show on one line the file format and most important informations * --mime: just display file MIME type . The command 'hachoir-metadata --mime' works like 'file --mime', and 'hachoir-metadata --type' like 'file'. But today file command supports more file formats then hachoir-metadata.
