Hello Spice developers and users, I'm going to apply for FOSDEM'14 Virtualization dev room with event "Media Redirection for Spice remote computing solution" (deadline is tomorrow...). The event would include a 20-minute lecture, 5-minute demo of a prototype and 10-minute Q&A session. Before I apply, I'd like to hear your comments on the proposed event (and you're the main audience of it!). I'd appreciate any comments about title, abstract, outline and the presentation drafts (http://www.spice-space.org/wiki/images/b/b9/Fosdem2014-lyakhov-v2.pdf). Hope that with your comments I can get this application better and get it accepted. Title: Media redirection for Spice remote computing solution Subtitle: Optimizing media stream processing for media players and VoIP clients in virtual desktop infrastructures Abstract: Handling of media streams is suboptimal in virtual desktop infrastructures if it is done at virtual machines. Consider two main use case: * Playback of a media stream from remote server e.g. user watches Youtube * IP telephony e.g. user makes a video call In both cases media streams are not delivered to the user's device directly but transcoded at the virtualization server. This results in increased network load, server CPU load (less VM density), quality loss of media streams. A solution for this problem, Media Redirection for Red Hat Spice remote computing system is proposed (www.spice-space.org/page/Features/MediaRedirection). Solution concept introduces following components: Media Engine and RPC-like service at user's device, Media Engine stubs and RPC-like client at Guest OS. To integrate the solution with Spice, new Spice APIs are proposed: API for establishing virtual channels and API for overlay rendering. A working Media Redirection prototype will be demonstrated using a demo audio player, Apache Thrift as RPC system, GStreamer as Media Engine. The event will be interesting for remote computing system developers and users (in particular, Red Hat Spice), RPC system developers and users, media engine developers, media player and IP telephony client developers. Note: the authors are NOT working for Red Hat, this work is being done by volunteers in their spare time. Outline: * Common media processing usecases * Red Hat Spice overview * Description of media stream processing problem in VDI * Media redirection concept description * Media redirection prototype description and demo * Feature evolution plan Discussion topics: * architecture & design considerations * new Spice APIs for virtual channels and overlay rendering * fault-tolerance practices (crash, disconnect) -- Best regards, Fedor _______________________________________________ Spice-devel mailing list Spice-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/spice-devel
