Sorry, I cannot comment on this.

Another way to see some output is to quit the already running media_server, 
and launch a new instance in a terminal. You should also see the output 
from the nodes that are loaded by the addon server, because that one is 
started by the media_server, so it's output should also be routed to the 
terminal.

AFAIK, only what is in the BeBook. I think there is a virtual function 
"WantsAutoStart()" or something. And you can specify if your node is a 
"Physical" Input/Output. That might help too.

I know media node development can be challenging, particularily because 
documentation is sparse. Your best bet is to look at the existing nodes in 
the Haiku tree. Those were either done by knowledgable people and/or are 
based on sample code from Be. So they provide the most up to date 
"documentation" you can get.
