No.Rosegarden or other Audio/Video Editing software are not going to Use Phonon.Phonon is NOT Designed for them.Its Designed to support Basic functionalities that __ALL__ of its Engines support.For example Playing and Pausing Audio is supported by all engines.but more advanced things which are needed for Editing are not implemented in all engines.
every video/audio editing application (Usually) uses One Engine.
sorry if im wrong.Im just a user and i know these by reading mailing lists/talks...

As a musician I use all the applications like Rosegarden, Ardour, ... directly with jackd, no need for Phonon. But therefore I have to connect the jackd deamon via Alsa to my prefered sound device.
Now I would be realy glad if KDE via Phonon could make use of jackd. If not, I would have to connect KDE to a different sound device because the one used by jackd is already blocked. Right?

Hey Germel,

Hopefully somebody will implement a jackd backend for phonon. However the linux kernel has something called dmix which basically allows multiple 'apps' to open the sound device, so it won't be blocked.

There can not be such a thing as a jackd backend for Phonon. A Phonon backend does decoding of arbitrary media formats and in addition to audio playback also does video.

What is needed are jackd output plugins for the libs that are used by the backends. Those outputs are, AFAIK, already available for GStreamer and Xine.
