I did just try this and VLC doesn't use PAUSE against your server at 
all, it continues the stream and buffers internally.  It looks like it 
decides whether the input is able to pause based on whether it knows the 
duration (f_npt_length) - could this be because you don't return the 
duration in the SDP, so it looks like a live stream?

  ...
  a=range:npt=0-
  ...

Because the VLC live555 module never enters true PAUSE state the 
doEventLoop() still gets called by Demux() and hence you handle the 
GET_PARAMETER responses instantly.

Proper fix to both ends soon...

Best regards
