In line 1124: if (d <= sampleCount * sampleDelta), there is a change for an 
integer wraparound here. 

d is of type MP4Duration, which is unint64_t. The multiplication is of two 
uint32_t. 

A simple change would be to cast of the operands to MP4Duration which would 
convert both of the operands to MP4Duration before multiplication.

I am using the latest version of mp4v2.
