Specifying an exact start time makes playback startup slower, which is not always what we want. We should add tolerance parameters (like for seeks) to let applications decide whether they want playback startup to be precise (at the expense of startup time) or it the startup position can be less precise (improving startup time).
There is only one specific requirement which needs to be taken into account: No matter the precision, starting playback within a segment must ensure that the initial playback position stays within the segment. The tolerance must therefore be adjusted depending on the initial target position within a segment.
Some unit tests need to be written as well to cover these specific cases.
