问题 Does anyone knows how to install the python library pyexiv2 and/or Gexiv2 on Mac OSX, ideally on version 10.6.8 and in a virtualenv? 回答1: It's pretty simple with Homebrew package manager: brew install exiv2 pyexiv2 If you're using Macports, it also has exiv2 formulas: http://www.macports.org/ports.php?by=name&substr=exiv --Edit-- A side note: I got segfault at "import pyexiv2". It turned out I have system Python 2.7.2 and homebrew Python 2.73 intalled at the same time. The problem disappeared

Python native library to read metadata from videos?

Is there a Python library to read metadata (camera model, time created, etc ...) from video files? The Perl equivalent is "exiftool." I checked pyexiv2, but it doesn't have video support like exiftool does. Thanks. I have used hachoir-metadata succesfully: http://pypi.python.org/pypi/hachoir-metadata I have used PyExifTool , a wrapper for the command line program, exif tool.
