My setup:
Macbook Pro (Mid-2012)
OSX El Capitan 10.11.2
PMS: 0.9.12.19
I can play things fine in Firefox, but nothing ever begins to play within Chrome. I can navigate around just fine, and I can select a video to play, but the video never actually begins to play, just sits there at 0:00 and never advances. If I skip ahead on the timeline to another point, the individual frame will sometimes load, but again, it will never actually move ahead and play.
Anyone else having this problem?
