https://blueprints.launchpad.net/linaro-multimedia-testcontent/+spec/engr-testcontent-shortversions

Essential

Create short version test contents(3-5s) for sanity test use

Short version test contents upload to samplemedia.linaro.org and also packed in samplemedia debian package

Released - package was created in https://launchpad.net/~alsuren/+archive/linaro/+packages and was requested to upload to a Linaro PPA. Also a tarball is available via the milestone page

Medium

PNG is the standard format for non-photographic images on the web. These optimisations allow faster rendering of web pages using less power

Improved decoding speed in benchmarks, exact speedup depending on source image. No regressions

Released version 1.5 of libpng (platform PPA + tarball on milestone page). Note that Ubuntu currently has version 1.2 but upstream has moved on to 1.5

Missing Headline and Acceptance, delivery will move to 2011.11. The work has started - analysis is in https://wiki.linaro.org/WorkingGroups/Middleware/Multimedia/Specs/1111/AudioIntegration/UCMPulseAudio/Analyzation

https://blueprints.launchpad.net/libjpeg-turbo/+spec/engr-mm-codec-jpeg-jcs-rgb565

Medium

libjpeg-turbo code for all architectures, now includes support for 565 encoded images

Libjpeg-turbo is able to encode and decode 565 encoded images. Android use of 565 is able to run successfully, Android specific extensions to the ABI are included, new testcases are included, existing testcases are extended, and runs faster than the Android version

Risk item - code is there, how to best generate / obtain test images less than obvious

libjpeg-turbo code for all architectures, now includes support for Android's JCS_RGBA_8888 encoded images

Libjpeg-turbo is able to encode and decode JCS_RGBA_8888 encoded images by extension of the JCS_EXT_RGBA support. Android use of JCS_RGBA_8888 is able to run successfully, Android specific extensions to the ABI are included, new testcases are included, existing testcases are extended, and runs faster than the Android version

Medium

Optimization of x264 using preload engine

User can use preload engine to improve L2 cache hit for x264

Community effort - PLE working but optimization is not obvious
