- # geb666: original bsc.py, based on work by Giacomo Bordiga
- # jmdsdf: version 2 adds extra ID3 and EXIF tag support
- # jmdsdf: added better error handling for ID3 tags, added mp3 length support, distinguished
- # between exif image size and true image size
- # SabreWolfy: set consistent hh:mm:ss format, fixed bug with no ID3 information
- # throwing an unhandled exception
- # jmdsdf: fixed closing file handles with mpinfo (thanks gueba)
- # jmdsdf: fixed closing file handles when there's an exception (thanks Pitxyoki)
- # jmdsdf: added video parsing (work based on enbeto, thanks!)
- # jmdsdf: added FLAC audio parsing through kaa.metadata (thanks for the idea l-x-l)
- # jmdsdf: added trackno, added mkv file support (thanks ENigma885)
- # jmdsdf: added date/album for flac/video (thanks eldon.t)
- # jmdsdf: added wav file support thru pyexiv2
- # jmdsdf: added sample rate file support thru mutagen and kaa (thanks for the idea N'ko)
- # jmdsdf: fix with tracknumber for FLAC, thanks l-x-l
- # draxus: support for pdf files
