Notes from kick off session Monday:

What additional things to hack/discuss during the week


Additional or different codecs

  • discussion as prep for codec optimization plans

Tools for validation for codec profiling

  • Set of clips - test samples
  • Encoder validation - specific bit rates, etc Speed vs. "good enough" - no standard for quality
  • Perf, oprofile

Audio validation

  • also difficult to validate

Test formats

  • links to formats and boundry cases that are outside the top 10%
  • Act as aggregation of content that hit most popular user cases
  • Not plan in corner cases requiring indepth codec experience, leave that to the test format companies

Test tools/frameworks


  • Less user space focused, out of band
  • Managed by the application
  • GStreamer in caps
  • Buffer sharing - handle passing
  • Refcounting hidden from user space
  • DRI for non-android
  • Documentation session - hacking docs for UMM for User Space recomendation
    • Outline and whiteboard discussion
    • not User Space focused, so application viewpoint, Xorg driver, ect
    • Impact to existing multimedia
    • Relationship to Android - Compare and contrast with ION
    • OpenMAX tie in
    • OMAP example, reference implementation description
  • Parser?


Audio use of UMM work

  • Define the role of Linaro in Khronos/OMX and Android - are we the conduit
