  7. High level libraries • Telepathy and Farsight for VoIP and Videoconf • Rygel or Coherence for UpnP/DLNA support • Gnonlin for video editing support • Gst-RTSP-server for advanced RTSP services

  8. Playbin2 • Autoplugger • Encoded output • Improved HD support • Improved streaming support • Congestion support, on-disk buffering • Decodebin2 • Faster, more versatile, better memory usage

  9. RTP Support • Playbin2 with full RTSP support • RTP stack popular (Axis, Tandberg) • Windows Media, Real Media, MPEG, Ogg • gst-rtsp-server

  10. Intelligent Download Buffer • Visual feedback of download progress • Intelligent pausing if network can not keep up • Quicktime/YouTube style • On-disk buffering

  11. Collabora Multimedia • Unlike a lot of open source projects, Gstreamer has well established professional support • World Leading experts on GStreamer

  12. OpenMax Support • GStreamer Integration with OpenMax IL • Bellagio/ST 100% supported • ... easy path to native GStreamer support

  13. OpenGL support • gst-plugins-gl module • OpenGL based video output (xvimagesink replacement) • OpenGL ES 2.x support • Enable video processing on the GPU in a GStreamer pipeline • Any OpenGL video filters

  14. DVB Support • DVB-T, DVB-S, DVB-C, ATSC tested and confirmed working • Deinterlacing, MHEG, scanning still to be done

  17. Farsight2 and Telepathy • Integrated VOIP and videoconferencing toolkit • SIP, Gtalk and others • Many to many • Collaboration

  18. Various New Plugins • New core and base release with improved support for interlaced media • New high quality deinterlacer • New fast tag reading system • Camerabin • Quicktime, MP4 and 3GPP muxer • MXF demuxer and muxer

  19. GStreamer and Mobile Platforms • LiMo • Access • GPE • Maemo • OpenMoko • Moblin

  20. Gstreamer and Android • Establish easy to build setup for putting Gstreamer on Android • Optional integration of Gst-OpenMax • Write java gluecode to link Gstreamer with existing Java multimedia APIs in a transparent manner • Propose and write new Java APIs to expose all new features available through GStreamer

  21. Editing • Collabora putting a lot of effort into Gstreamer editing functionality • Central core is the GNonLin set of editing plugins • Synergy between embedded and desktop due to Pitivi

  22. Editing Embedded • Support basic features like cutting/trimming, adding/removing audio, simple text based introductions/credits • Possibility to use some OpenGL based effects and transitions • More editing features available for more high end devices • Collabora to provide higher level helper library
