--- Comment #1 from Konstantinos Margaritis <konstantinos at vectorcamp.gr> ---
Ok, Similarly to VP9, as VP8 is implemented in the same libvpx library, an
SVP64 version of of the VP8 DCT 4x4 has been completed in commit 

https://git.libre-soc.org/?p=openpower-isa.git;a=commit;h=343853a711ca2dded15f8a713370a61454f2627f

Implementation method was similar to VP9 ticket:
