libjpeg-turbo

September 22

https://launchpad.net/libjpeg-turbo/+milestone/1.1.90-2011.09

Not released yet

Android release has been made: check this thread in linaro-dev. Patch also accepted upstream - new BPs created for this work to follow the stream of patches upstream (under backlog in https://launchpad.net/libjpeg-turbo/+milestone/backlog). Latest status: updated to r702, submitted into revu, feedback received, acted on FFe bug evaluated and seems to have support for ltj to be included in oneiric, fabo working on debian acceptance

UCM Audio integration

September 22

https://launchpad.net/linaro-multimedia-ucm/+milestone/2011.09

Not released yet - a release is made needs to be included in the official release

Complete implementation and testing of baseline UCM configurations for ARM reference platforms. Snowball related testing is now postponed for after 1109 as snowball ubuntu support for audio still has issues

Codec optimization

September 22

https://launchpad.net/linaro-multimedia-x264/+milestone/2011.09

Release made through the wiki: https://wiki.linaro.org/WorkingGroups/Middleware/Multimedia/Specs/1111/CodecOptimization/x264

Community optimization of x264 codec for ARM - parameters optimization: instructions given in the wiki

September 22

https://launchpad.net/linaro-multimedia-testcontent/+milestone/2011.09

Not released yet

Shortened versions of the files are prepared and uploaded to samplemedia.linaro.org (the current gstreamer tests can do everything they need with just 2-5 second samples. 45-75 second samples are more useful for benchmarking than sanity/regression testing, so the extra MBs are mostly wasted)

OpenMAX

September 22

Milestone: https://launchpad.net/linaro-multimedia-project/+milestone/2011.09, Blueprint: https://blueprints.launchpad.net/linaro-multimedia-project/+spec/engr-multimedia-openmax-survey

DONE - missing a report from Benjamin Gaignard on the event participation

Present the survey results to OpenMAX IL WG

NEON optimization

September 22

Milestone: https://launchpad.net/linaro-multimedia-project/+milestone/2011.09, Blueprint: https://blueprints.launchpad.net/linaro-multimedia-project/+spec/engr-multimedia-forum-summit

DONE

Finalize the presentations from the summit - material available through https://wiki.linaro.org/WorkingGroups/Middleware/Multimedia/Specs/1111/NEONOptimizationForum/Summit

Team Highlights

  • On 1109 progress is being made: LJT is well on its way for inclusion to Oneiric, UCM has made a release, ARM Speex is in the works. Also omapdrm (for UMM) is now available through Jesse Barker's git tree. NEON optimization Forum material is already consolidated in the wiki, OpenMAX survey has been presented to OpenMAX IL WG meeting.
  • Brainstorming over the next quarter possible threads of work (in no particular order)
    • libpng optimization
    • better video rendering integration in UI
    • Audio DTS decoding - could be tricky, involves legal aspects which need to be carefully looked at
    • Compressed data sound support (as in http://www.linuxplumbersconf.org/2011/ocw/proposals/633)

    • Realvideo on ARM (popular on countries like China) - needs optimization for eg 720p playback (VGA is ok)
