There's been reports of dropped frames that are not counted and correctly reported by getStats(). If a HW decoder is used and the system is provoked by stressing the system, I've been able to reproduce this problem. It turns out that we've missed frames that are dropped because there is no callback to the Decoded() function. This CL restructures the code so that dropped frames are counted even in cases where there's no corresponding callback for some frames.
