aRts short introduction Multimedia API for KDE 4 Matthias Kretz Introduction Where We’re Coming From for KDE 2 aRts was adopted as the soundserver and Media Frameworks mediaframework KDE Multimedia Efforts best available framework at that time aKademy ’04 Why KDEMM works well for a lot of people The design of KDEMM at this has a rich featureset point new API for KDE4 User Visible Features the possibilities of MCOP were never really exploited API Usage in KDE Summary Appendix

aRts Known Problems Multimedia API for KDE 4 Matthias Kretz not maintained since a considerable time Introduction Where We’re Coming From design issues Media Frameworks KDE Multimedia debugging artsd or aRts applications is hard Efforts aKademy ’04 new scheduler core made a lot of people reject aRts Why KDEMM because of its glib usage The design of KDEMM at this point using aRts in your application isn’t easy enough new API for KDE4 User Visible Features developing for the aRts core is even harder API Usage Summary not enough adoption outside of KDE Appendix whatever you’re favorite complaint is. . .

NMM Network Multimedia Middleware Multimedia API for KDE 4 Matthias Kretz clean C ++ API Introduction Where We’re Coming From Media Frameworks completely network transparent KDE Multimedia supports sharing of media resources that seems Efforts aKademy ’04 very attractive for desktop usage (example: the same Why KDEMM The design of music playing in two rooms) KDEMM at this point Michael Repplinger: “Since we are, from our side, new API for KDE4 User Visible Features very interested that NMM becomes a backend for the API Usage multimedia-part in KDE4, I will try to create a working Summary version as fast as possible.” Appendix

aKademy ’04 Multimedia API for KDE 4 Matthias Kretz The largest gathering of KDE Multimedia developers in history Introduction Where We’re Coming From We had talks about media frameworks Media Frameworks KDE Multimedia We talked about our options: Efforts aKademy ’04 Adopt one of the existing media frameworks as the 1 Why KDEMM KDE framework The design of KDEMM at this Adopt one of the existing media frameworks and 2 point write an API that is more suited to KDE developers new API for KDE4 User Visible Features (C ++ , signals/slots, Qt style API) around it API Usage If we write our own API, why not make the 3 Summary implementation of the API completely independent, Appendix thereby allowing different media frameworks to implement the API’s functionality

What is KDEMM ? Multimedia API for KDE 4 Matthias Kretz Introduction Where We’re Coming From Media Frameworks It’s a boring name I invented to have some name to KDE Multimedia Efforts call my project. I’m open for better name suggestions aKademy ’04 Why KDEMM It’s a library that is to reside in kdelibs (currently in The design of branches/work/kdemm) KDEMM at this point new API for KDE4 It’s targeted for release with KDE 4 User Visible Features API Usage Summary Appendix
