:-) yep that one! And the driver source, while constructed out of gpl
software, was never released. And thus still closed software. Illegal,
gpl violating, but closed. Their attempt to rectify was to create a
open source stub driver and a closed source userspace part, consisting
of obfuscated FFMPEG code. 
Luc Verhagen, et al. explained and barked loudly at Allwinner on what
they had to do to rectify. But I guess the IP owner of cedarx is not
AllWinner. And their vendor, the IP owner, the original infringer, did
not give them permission to rectify properly. Or something else.

sunxi-vdpau is open source but it is a hack. An unsafe one! 
sunxi-cedrus is not ready for primetime last time I checked. V4L is
slow to accept the needed changes.
