Nice touch.

Does encoding/decoding work on -next sans interconnect support ? I think 
we discussed on IRC it does but I'll ask again just to confirm.

(We have no use-case for encoding.)
Decoding works, of course.
I would not submit a broken feature :)

(vp9 2560x1440 59.940fps) decodes at x2  (122s for 240s)
(vp9  854x480  29.970fps) decodes at x15 ( 16s for 240s)

I find the performance quite decent.
Though I would have expected a larger performance ratio:
2560x1440 59.940fps = 221 Mpixel/s
 854x480  29.970fps =  12 Mpixel/s

If 1440p decodes at x2, 480p should decode at x30 ?
Or maybe the bottleneck is elsewhere :)
