According to spec, AUD is optional. Chapter 7.4.1.2.3 is not too
complicated to implement and most often sufficient.

For complete support, 7.4.1.2.4 is required too, but more
compliated and cannot be implemented without in depth parsing of
several H.264 data structures.

As vdr-xine doesn't implement the later and seems to work for
this kind of stream (see this thread), implementing the former
should fix this issue.

Bye.
