Excellent!
- 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-libs... ),
benchmarking ltj with tjbench
Is there any optimization (or indeed implementation) work being done here by anyone in the MMWG itself (i.e. excluding Tom)?
Tom willingly jumped on this work when we didn't have anyone else and has done a great job. Mans has been advising as needed. I see no need to take it away from Tom just because he isnt officially in the MMWG.
- 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
That's correct -- even if Snowball lacks an IOMMU for the hardware codecs, it should be able to use CMA to get access to a contiguous area and the dma-buf API should work for it. Who is working on this?
Jesse and I are discussing who does what, but from the mmwg I would like Benjamin to work on this, probably with someone else from his team.
- Testing dts decoder with gst-ffmpeg on panda and i.mx53 (mkv + dts 6ch)
Nice -- what are the results looking like?
Please feel free to ask any questions or let me know if you believe that something is missing
Can you get the requirement laundry list polished up a little bit and sent to the TSC for feedback if any topics there look worth pursuing further into requirements?
There are only 3 left from the list that are bounded enough to consider: 1) Compressed data api into ALSA - driver specific kernel work and ALSA/ASoC plumbing, prob not a good fit for mmwg yet 2) ALSA port of ST-E drivers - also prob not a good fit for mmwg, already proposed as a possible requirement for the new STG team in that mail thread 3) End to end audio tests for integration - new proposal by Alexander, blueprints are already created, investigation underway, but I can write up a papyrs page for it if we need to take it in front of the TSC
