Sure, but the lost packet event should be thought of as a "replacement buffer",
and then it make sense that it, just like the buffers, are redirected according
to its (assumed) payloadnumber. However, at the moment there is no
payloadnumber info on the event, only seqnum, timestamp and duration. Also,
when using the default handling in the basedepayloader, the lost-event is
translated to a newsegment, and that can't have any knowledge of
payloadnumbers.

So I guess the other option would be:
1. Add payloadnumber to the lost-event. (priv-last_pt)
2. Add a filtering on the basedepayloader, checking if the lost-event received
matches the configured pt.

What makes me a bit sceptical of this approach is that you would be sending the
lost events to all depayloaders (with the same ssrc), making them do accept or
decline. In my head this is similar to sending all buffers to all depayloaders,
making them do the job that the ptdemux is there to do.
