Proposal for KDE media interface

[Avi]

Very good initiative!
Some comments:

- Think about integrating it with the kfile_* framework. KFile has the
ability to get some meta info from the files, like bitrate and ID3 tags.
- There are many media formats that are not based on encoded media, like
Flash, or some Real content, or Midi. A generic player using your API
should be able to play these formats also.
- The most important thing is a documentataion about how to write
plugins.

Thank you,
Avi
