Designing the segmentModifier

Design the segmentModifiers portion of the destination path. The segmentModifier is optional, and if you include it, only the media file names include it.

A typical use case for this modifier is to use a data variable to create a timestamp, to prevent segments overriding each other if the channel restarts. For example, assume that you include the timestamp $t$-. Segment 00001 might have the name index-120028-00001. If the output restarts a few minutes later (which causes the segment counter to restart), the new segment 00001 will have the name index-120039-00001. The new file won't overwrite the file for the original segment 00001. Some downstream systems might prefer this behavior.
