Hinweise
This method performs a shallow copy of the presentation descriptor. The stream descriptors are not cloned. Therefore, use caution when modifying the presentation presentation descriptor or its stream descriptors.
If the original presentation descriptor is from a media source, do not modify the presentation descriptor unless the source is stopped. If you use the presentation descriptor to configure a media sink, do not modify the presentation descriptor after the sink is configured.
