Re: [linux-audio-user] New Sound Subsystem Needed For Qt4/KDE4

Hi, 2005/7/29, Mark Constable <markc(a)renta.net>et>: You should subscribe to kde-multimedia(a)kde.org and ask the question there. The short answer is: KDE doesn't need jack or portaudio or alsa. It needs a soundsystem or even better a sound-api which it can tell "play me file XYZ", "play video YQ with the sound going through that filter and with that volume". These are things that basic alsa/jack/portaudio can't do. The obvious answer would be xine/mplayer/gstreamer/arts. The experience with aRts tells use not to focus on one soundsystem and get lost if that is not maintained anymore. Thats why the kdemultimedia-devs (Matthias Kretz, Scoot Wheeler and some more) decided to create a layer between the running soundservers and the KDE-apps. This has the advantages that the normal KDE-dev doesn't care about what system is underneath. And that KDE can change the default soundserver (or even the distributions can change the default). Gstreamer will probably be the first choice for the default server but there are also tests with NAS, NMM, xine and some more going on... Please say good-bye to the thought of jack as the soundserver for everything. Jack is for professional raw datastreams with very little latency. For the typical desktop-app/game its irrelevant how much latency there is (if its not 2 secs) but it wants to play mp3 without thinking about encoding it... And yes, I am an official kde-mm-developer, I wrote KRec and do the translation of the gui and docs into german. And I suffered with aRts from the devels view...
