it's the most messy player around and also the least academical ;)
ffmpeg is much cleaner, but it doesn't expose how to use
PCR wrt to DTS and PTS.
To make it short: you can consider the PCR your "wallclock",
the DTS and the PTS are then timestamps when you should
begin to decode and display, respectively.
In a stream the DTS and PTS are always > PCR, thus you
have to buffer packets (PES payloads) and dispatch each packet whose
[PD]TS is <= last PCR seen to the respective decoder/player
