Title: Re: CAClockSetCurrentTime Help
Here are the values that I am assigning to clockTime.time. I am including the console readout and the code that works to convert SMPTE to seconds.
Thanks, Chad
{
OSStatus err;
//SMPTETime smpteTime;
CAClockTime clockTime;
//CAClockSeconds seconds;
NSLog(@"SMPTE Time - %2.2hi:%2.2hi:%2.2hi:%2.2hi",(SInt16)[hhField intValue], (SInt16)[mmField intValue], (SInt16)[ssField intValue], (SInt16)[ffField intValue]);
clockTime.format = kCAClockTimeFormat_SMPTETime;
clockTime.time.smpte.mType = kSMPTETimeType30;
clockTime.time.smpte.mHours = (SInt16)[hhField intValue];
clockTime.time.smpte.mMinutes = (SInt16)[mmField intValue];
clockTime.time.smpte.mSeconds = (SInt16)[ssField intValue];
clockTime.time.smpte.mFrames = (SInt16)[ffField intValue];
clockTime.time.smpte.mSubframeDivisor = 80;
clockTime.time.smpte.mSubframes = 0;
err = CAClockSetCurrentTime(clockRef, &clockTime);
if (err != noErr) {
NSLog(@"SMPTETimeToSecond err = %d", err);
return;
}
/*
smpteTime.mType = kSMPTETimeType30;
smpteTime.mHours = (SInt16)[hhField intValue];
smpteTime.mMinutes = (SInt16)[mmField intValue];
smpteTime.mSeconds = (SInt16)[ssField intValue];
smpteTime.mFrames = (SInt16)[ffField intValue];
smpteTime.mSubframeDivisor = 80;
smpteTime.mSubframes = 0;
CAClockSMPTETimeToSeconds(clockRef, &smpteTime, &seconds);
CAClockTime secondTime;
secondTime.format = kCAClockTimeFormat_Seconds;
secondTime.time.seconds = seconds;
CAClockSetCurrentTime(clockRef, &secondTime);
