[gst-devel] sync

[ved k. <ve...@gm...>]

hi
i would like 2 know exactly how the syncing is done.
i didn't understand some things when i went thru the basesink,baseaudiosink
files. why, in the baseaudiosink ,the gettimes func returns the the null
values for the start & end time for the buffer, whereas in the basesink it
returns the the actual values. i got a little confused when i went thru
them.so does that mean that for audio, the buffer nevers go  thru the wait
call . i would also like to know how the  xvimagesink uses  the clock
provided by the the baseaudiosink which increments the time based on the th=
e
sampling rate(samples processed). how does that clock become global
automatically?,meaning how the other elemnets in the pipeline refer to that
clock.
if the sink uses gstsystemclock (provide-clock=3Dfalse), will all the eleme=
nts
basetime be set to current system time ? i would also didn't understand the
paramaters internal & external in  gst_clock_set_calibration.
thanx
