Can you  create these as kClockless type tests? We're starting to get too many
of these and they take #media_duration in real-time to complete.

[vignesh, 2016/01/06 00:07:49]

I have marked these two as kClockless. Would you like me to change the other
BasicPlayback_VP{8,9}_* tests as well?

[DaleCurtis, 2016/01/06 00:16:48]

Sure, if they all still pass.
