<p>This generates six single-segment media files, one per stream, spanning multiple
periods. There may be problems handling this type of DASH contents in some
players, although it is recommended by <a class="reference external" href="http://bit.ly/2B0HL9q">DASH IF IOP</a>.
Use the below option if your player does not like it.</p>

For DASH, multiple periods will be generated with period boundaries at the
