/** @file timings.hpp
|
|
** How to define a timing specification or constraint.
|
|
** A timing spec is used to anchor an data stream with relation to a time axis or frame grid.
|
|
** There are two kinds of timing specs:
|
|
** - nominal timing specifications relate to the nominal time values
|
|
** of the frames in a data stream, i.e. the "should be" time values.
|
|
** These might be values derived from a timecode or just values in
|
|
** in relation to the timeline axis, but without any connection to
|
|
** the real wall clock time
|
|
** - actual timing specifications are always connected or related to
|
|
** an external time source, typically just wall clock time. For example,
|
|
** actual timing specs dictate the constraints for real time frame
|
|
** delivery to an external output connection.
