14, but nit/whatever

[Taylor Brandstetter, 2017/01/19 17:23:08]

It would be reasonable to have a DCHECK for "frames_rendered < frames_decoded"
though, so if this is changed it should probably be decoded=14, rendered=13.

[hbos, 2017/01/23 12:12:15]

Changed the order so that it's ..., 12, 13 (rendered), 14 (decoded).
