Meeting notes:
https://wiki.linaro.org/WorkingGroups/Middleware/Multimedia/Notes/2011-09-27

Highlights:

- Working on 11.10 plans

- Decision on the multimedia content licenses is still pending - TSC to
provide guidance

- libjpeg-turbo - oneiric upload, 11.09 natty version released to
ppa:linaro-maintainers/overlay, implemented and submitted upstream
(Blueprint:
https://blueprints.launchpad.net/libjpeg-turbo/+spec/engr-mm-codec-jpeg-libstartup),
benchmarking ltj with tjbench

- Studying dma-buf scatter list feature - useless on snowball - snowball
doesn't MMU on hw IP. Could use something like sg_is_last() or
sg_is_chain() to say that there is only one piece of memory in the
scatterlist, but the idea for using scatterlist is that the API should
handle both cases - both devices that need contiguous and those that don't

- Working on the UMM testing for the Freescale i.mx5 platform

- Extracted dri2 into a separate lib for mesa (since it will be easier
to extend dri2 for video). Added omap support in libdrm... still work in
progress

- Testing dts decoder with gst-ffmpeg on panda and i.mx53 (mkv + dts 6ch)

- Working on the requirements for next quarter - discussion ongoing in
the team taking also feedback from the rest of Linaro:
  * https://linaro-public.papyrs.com/public/4157/MMWG2011-UCM-FOR-ANDROID/#
  * https://linaro-public.papyrs.com/public/4156/MMWG2011-UMM-CAMERA-DEMO/#
  * UMM - split discussed between Jesse Barker and Kurt Taylor
  * Other requirements being looked at (missing though either blueprints
or requirements in papyrs at the moment)
    + libpng optimization - blueprint in backlog
https://blueprints.launchpad.net/linaro-multimedia-project/+spec/linaro-mmwg-png

    + Better video rendering integration in UI, like X11 proposal for
wayland, extended dri2

    + Audio DTS decoding - could be tricky, involves legal aspects which
need to be carefully looked at, already done in libav?

    + Compressed data sound support (as in
http://www.linuxplumbersconf.org/2011/ocw/proposals/633)

    + Realvideo on ARM (popular in China) - needs optimization for 720p
playback, VGA is ok. Blueprint: https://blueprints.launchpad.net/linaro
multimedia-project/+spec/linaro-mmwg-realvideo

    + armv6 optimizations for vp8, and 10-bit h264 optimization, both in
libav - Blueprint:
https://blueprints.launchpad.net/linaro-multimedia-project/+spec/linaro-mmwg-libav

    + Further enhancements and optimization for LJT - Blueprint:
https://blueprints.launchpad.net/linaro-multimedia-project/+spec/engr-multimedia-codec-jpeg

    + UCM for Android - Blueprint:
https://blueprints.launchpad.net/linaro-multimedia-project/+spec/linaro-mmwg-ucm4android

    + 3D video stream

    + secure streaming (like netflix)

    + audio library optimization

    + Directfb NEON optimization - Blueprint
https://blueprints.launchpad.net/linaro-multimedia-project/+spec/engr-multimedia-directfb-neon-optimization

    + Audio testing - basic (Blueprint:
https://blueprints.launchpad.net/linaro-multimedia-project/+spec/linaro-mmwg-e2eaudiotesting-basic)
vs speech (Blueprint:
https://blueprints.launchpad.net/linaro-multimedia-project/+spec/linaro-mmwg-e2eaudiotesting-speech)


Please feel free to ask any questions or let me know if you believe that
something is missing

Best,
