RangeError — If the index is out of range.
From OSMF 2.0 upwards you can set the initialIndex through a metadata as
well, using the RESOURCE_INITIAL_INDEX key. This metadata can be added to
any media resource, such as an URLResource, and it will be used to set
the initial index when the DynamicStreamingResource is created.
For example, having resource as a URLResource you can set the initialIndex
in the following way:
resource.addMetadata(MetadataNamespaces.RESOURCE_INITIAL_INDEX, 1);
The RESOURCE_INITIAL_INDEX metadata accepts integers, and will adjust the
value to fit into the streamItems range. This means that if the specified
value is negative it will be adjusted to 0, and if it is larger than the
available streamItems, then it will be adjusted to the greatest streamItem
index.
