[kde-china] 回复： About the Qt Phono

[Liang Qi]

Phonon就是一个框架，可以理解为中间层

http://doc.trolltech.com/4.4/phonon-overview.html
Qt uses the Phonon multimedia framework to provide functionality for
playback of the most common multimedia formats.The media can be read
from files or streamed over a network, using a QURL to a file.

http://phonon.kde.org/cms/1020
Phonon wants to fill in the gap and provide a multimedia API for KDE
developers while at the same time giving the users more choices. With
Phonon applications don't need to develop sound engines as Phonon
provides them for free. Applications are written saying what they want
and not how they want to do it. This leaves some room for the
user/administrator to customize things.

If you need multimedia functionality in your program, Phonon is for
you. Use it from simple audio playback to full blown video playback
with audio and video effects. Use it to record an audio signal or
capture from a webcam. Use it to concentrate on your program and not
on getting the mediaframework to work for you.

至于Phonon下面是什么，完全可以自己去实现。

这个需要你自己去调研了
