This is interesting, is the work(source) available somewhere? > but gitorious has closed down and therefore the link > https://gitorious.org/recedro/jepoc > is no longer working. > Is this proof of concept for JPEG encoding on Allwinner A10/A20 > anywhere else available? http://dl.linux-sunxi.org/users/nove/jepoc.tar.gz Until a new place is found, a tarball should suffice. But as you well are aware, this a proof of concept with the function to prove that we understand how to use this hardware. And only that. It is not recommend to use this for any other function. The correct solution is to work for a proper driver for this video engine, and then work with the upstream people to assure proper support for the (random) software. But, it is seen that majority of the hardware vendors and its users are more interested to run around binaries blob with license ambiguity issues. Than to support the work this community (linux-sunxi) is doing. And off course with this unfavorable conditions, is natural this work for an 100% free-and-open-source proper driver is not at the level of advance that we all wish it to be.
