The latest cedarx code released by Allwinner is still non-GPL in the
important parts, and no indications that this will change any time soon.
Yes they have released much of the glue layers with GPL license, but the
actual video encoding/decoding parts is till in a binary library which
is incompatible with the GPL license terms.
For open and Linux desktop portable drivers then please take a close
look at the Cedrus open driver developed outside of Allwinner:
http://linux-sunxi.org/Cedrus
Please note that the security concerns mentioned in this project also
applies to Allwinners code as it stems from the Allwinner kernel API and
hardware capabilities, not the Cedrus code.
