objective c - Working with QTTime in milliseconds -


i current time of qtmovieview so:

qttime time = self.movieview.movie.currenttime; 

and put smpte form

nsstring *smpte_string; int days, hour, minute, second, frame; long long result;  result = time.timevalue / time.timescale; // second frame = (time.timevalue % time.timescale) / 100;  second = result % 60;  result = result / 60; // minute minute = result % 60;  result = result / 60; // hour hour = result % 24;  days = result;  smpte_string = [nsstring stringwithformat:@"%02d:%02d:%02d:%02d", hour, minute, second, frame]; // hh:mm:ss:ff 

but don't want have end frame number. want end in milliseconds (hh:mm:ss.mil)

the following should work:

double second = (double)time.timevalue / (double)time.timescale; int result = second / 60; second -= 60 * result; int minute = result % 60; result = result / 60; int hour = result % 24; int days = result / 24;  nsstring *smpte_string = [nsstring stringwithformat:@"%02d:%02d:%06.3f", hour, minute, second]; 

the seconds computed double instead of int , printed millisecond precision using %06.3f format.

(note days = result in code not correct.)

if prefer integer arithmetic can compute milliseconds qttime time with

long long milli = (1000 * (time.timevalue % time.timescale)) / time.timescale;
