Animated GIFs are transcoded to AVC because it is much smaller and thus also suitable for long/large animations. In addition, this commit adds support for more metadata fields such as frame rate, number of frames, file capture timestamp (unix milliseconds), media type, and software version. Support for SVG files can later be implemented in a similar way.
