/* It's prudent to also have a brief discussion about the CVTimeStamp.
|
||||
CVTimeStamp has five properties. Three of the five are very useful
|
||||
for keeping track of the current time, calculating delta time, the
|
||||
frame number, and the number of frames per second. The utility of
|
||||
each property is not terribly obvious from just reading the names
|
||||
or the descriptions in the Developer dcumentation and has been a
|
||||
mystery to many a developer. Thankfully, CaptainRedmuff on
|
||||
StackOverflow asked a question that provided the equation that
|
||||
calculates frames per second. From that equation, we can
|
||||
extrapolate the value of each field.
|
||||
|
||||
@hostTime = current time in Units of the "root". Yeah, I don't know.
|
||||
The key to this field is to understand that it is in nanoseconds
|
||||
(e.g. 1/1_000_000_000 of a second) not units. To convert it to
|
||||
seconds divide by 1_000_000_000. Dividing by videoRefreshPeriod
|
||||
and videoTimeScale in a calculation for frames per second yields
|
||||
the appropriate number of frames. This works as a result of
|
||||
proportionality--dividing seconds by seconds. Note that dividing
|
||||
by videoTimeScale to get the time in seconds does not work like it
|
||||
does for videoTime.
|
||||
|
||||
framesPerSecond:
|
||||
(videoTime / videoRefreshPeriod) / (videoTime / videoTimeScale) = 59
|
||||
and
|
||||
(hostTime / videoRefreshPeriod) / (hostTime / videoTimeScale) = 59
|
||||
but
|
||||
hostTime * videoTimeScale ≠ seconds, but Units = seconds * (Units / seconds) = Units
|
||||
|
||||
@rateScalar = ratio of "rate of device in CVTimeStamp/unitOfTime" to
|
||||
the "Nominal Rate". I think the "Nominal Rate" is
|
||||
videoRefreshPeriod, but unfortunately, the documentation doesn't
|
||||
just say videoRefreshPeriod is the Nominal rate and then define
|
||||
what that means. Regardless, because this is a ratio, and the fact
|
||||
that we know the value of one of the parts (e.g. Units/frame), we
|
||||
then know that the "rate of the device" is frame/Units (the units of
|
||||
measure need to cancel out for the ratio to be a ratio). This
|
||||
makes sense in that rateScalar's definition tells us the rate is
|
||||
"measured by timeStamps". Since there is a frame for every
|
||||
timeStamp, the rate of the device equals CVTimeStamp/Unit or
|
||||
frame/Unit. Thus,
|
||||
|
||||
rateScalar = frame/Units : Units/frame
|
||||
|
||||
@videoTime = the time the frame was created since computer started up.
|
||||
If you turn your computer off and then turn it back on, this timer
|
||||
returns to zero. The timer is paused when you put your computer to
|
||||
sleep. This value is in Units not seconds. To get the number of
|
||||
seconds this value represents, you have to apply videoTimeScale.
|
||||
|
||||
@videoRefreshPeriod = the number of Units per frame (i.e. Units/frame)
|
||||
This is useful in calculating the frame number or frames per second.
|
||||
The documentation calls this the "nominal update period" and I am
|
||||
pretty sure that is quivalent to the aforementioned "nominal rate".
|
||||
Unfortunately, the documetation mixes naming conventions and this
|
||||
inconsistency creates confusion.
|
||||
|
||||
frame = videoTime / videoRefreshPeriod
|
||||
|
||||
@videoTimeScale = Units/second, used to convert videoTime into seconds
|
||||
and may also be used with videoRefreshPeriod to calculate the expected
|
||||
framesPerSecond. I say expected, because videoTimeScale and
|
||||
videoRefreshPeriod don't change while videoTime does change. Thus,
|
||||
to calculate fps in the case of system slow down, one would need to
|
||||
use videoTime with videoTimeScale to calculate the actual fps value.
|
||||
|
||||
seconds = videoTime / videoTimeScale
|
||||
|
||||
framesPerSecondConstant = videoTimeScale / videoRefreshPeriod (this value does not change if their is system slowdown)
|
||||

||||
