[vlc-devel] 回复： Re: What's the value of clock refecen frequency aftercalling es_out_Control?

Hi:
    Thanks for your answer.
    Then comes a new question: 
     What the global VLC clock is?And where can I find its related code in the source tree?

In that piece of code, i_pcr is expressed in microseconds, and converted to
90kHz to make a valid MPEG Program Clock. Most likely i_pcr comes from the
global VLC clock, which is a 1MHz wall clock.
