Agenda

  • Welcome
  • previous actions status review
  • status update on texture pixmap
  • clutter/unity archive update
  • review linaro graphics WG topics for next cycle
  • camera-bin status

Minutes

  • Split call in two parts (Alexander)
    • Split call will happen in October when more multimedia folks join the team.
  • omap gfx drivers (Ricardo)
    • Packages (including modules, drivers, libs) are ready.
    • Need to push to public PPA at minimum and multiverse at best.
    • Not tried with linaro kernel but expected to work.
  • Camera-bin (Sachin, Rob)
    • ACTION: Rob to share more info/links with Sachin for camera-bin.
  • TSC next cycle topics/items (Alexander)
    • ACTION: All to review next cycle topics/items.
    • ACTION: All to email Jess, Alexander or Alexandros with interests from the topic/item list for next cycle.
  • OpenGL rendering sinks (Sachin, Rob)
    • Sachin thinks the right way to handle this is with EGL, not with rendering sinks in each framework.
    • Rob: GL in gstreamer is akward because of the threading model.
    • EGL sink in OpenMax using EGL texture stream

      • No sample implementation or reference on this.
    • Use EGL in compositor not in application
      • Use XV + window properties to identify texture stream.
      • The compositor can the use the info to render the stream.
    • Open problems
      • Need a way to kick the compositor process to update overlay.
      • Need a way to be able to switch to using HW overlays if compositing is not needed, so that gfx hardware can be powered-off..
    • Whole issue needs more investigation, there is no precedence.
    • ACTION: Sachin to drive the investigation and discussion on video rendering with EGL.
  • clutk/mutter/unity (Jammy, Alexandros)
    • Most clutk issues have been fixed already (working with clutter 1.2).
    • Still some errors with Mesa implementation, Jammy is using Freescale's implementation.
    • Need to fix Mesa in next cycle to support missing features.
    • ACTION: Alexandros to fix mutter to work with new linaro clutter packages.
    • ACTION: Alexandros and Jammy to try out a full mutter/unity stack.
  • Xorg conference update (Alexandros)
    • Release policy changes, adopting feature freezes.
    • Non-privileged X still has issues with input handling (when running multiple servers)
    • EGL/Gallium improved on desktop. Performance still not up to par with classic drivers.
    • Mesa has an EGL extension that allows drawing accelerated 3D on the framebuffer (without X).
    • Wayland still very experimental. Integrated display server and window manager.
