    Phoronix: Another ARM Video Decoder Being Reverse-Engineered

    While the binary wall has yet to fall with ARM SoC vendors in terms of providing open-source drivers -- namely when it comes to the graphics / multimedia blocks -- there's many active community projects for reverse-engineering these ARM blocks to provide open-source support. Here's another project that's being done for cracking the video decoder on a popular Chinese ARM SoC...

    CedarX vpu doesn't decode only 1080p, it can decode Quad HD 2160p and encode 1080p at full rate in h264 high profile, this is also an interesting point for lot of developers around video solution.

      Where can you ACTUALLY buy a device with this?

      I've seen this chip/SoC show up nearly every time the Rasberry Pi is mentioned, but it never seems to be available or easily purchaseable. Does anyone have a link?

        DX has a ton of products using the A10. Tablets to usb-stick-form-factor.

          It's a little shaming, or maybe a call to arms is required, that there's no mention of the AMLogic AML8726. This SoC actually has, unfortunately unlicensed atm, Open-source Video drivers, from what I was told.

          https://github.com/Pivosgroup/buildr...yer/src/amadec

          for example. Everything is there I believe, including the, unfortunately binary only, firmware.

          So at this time, the AMLogic, besides it's mali GPU, should be 'the' oss SoC!

            We're buying A10 tablets (Android 4.0) in bulk and selling them to our clients with our custom survey software installed (custom Android launcher).
            Example;
            http://www.bigboxsave.com/sinvige-m7...tablet-pc.html

            ignore where it says "1.5 GHz". Its some fair bit of "creative" mathematics that gets them to 1.5, including (but not limited to) adding the GPU frequency to the CPU frequency.
            Also ignore the manufacturer name and model number. That tablet's REAL name is "LY-F1", and there are community android builds available for it.

            Edit: BTW: HDMI out (mini-HDMI plug) and USB host.

              Yes, I heared about manual upgrading of frequecy of tablet pc too, anyway it is wiser to go for reviewers such as below for it before buying and do not only look at the specifications. but Cheap tablet pc do saves money.
