Mauro, here's my current understanding:

The values for PTS have to be defined in terms of a 90khz clock. 

So for 30fps video, the values for PTS per frame would be:

frame_num/30 * 90000

so 0, 3000, 6000, 9000...etc

The same math is being used here for audio, but instead we have the
total audio sample count and a 48000 samples/sec


I did miss this rounding error though, I'm sorry.
