Excellent!

Your translation seems correct to me.  Maybe there is a problem with the wrapper GStreamer::CLOCK_TIME_NONE.  
The original definition is

#define GST_CLOCK_TIME_NONE ((GstClockTime) -1)

GstClockTime is an unsigned 64 bit integer, so this expression will overflow.  The docs say the value should 
be 18446744073709551615 (i.e., 2^64-1).  What's the value of GStreamer::CLOCK_TIME_NONE for you?  (I can't 
test right now.)
