[AG-TECH] How to develop a new service for AG?

Hello everyone!

I am currently in the process of writing a small service for AG which 
basically just calls a program with multicast-ip/port/ttl. Nothing to 
configure here. So basically it is like rat. Still it is not of type audio 
or video. Therefore I assumed to introduce a new capability e.g. IMAGE . 
Additionally I thought I could take the AudioService.py script as a basis 
and just modify it as the tool I want to integrate into a service behaves 
the same way as rat does.

When I thought about the port configuration of my new service, I relaized 
that ports are specified in the Venue Management tool of the VenueServer. 
The section for modifiying the ports there seem to be quite hardcoded 
without space for other services. Is that true? Do I have to extend the 
Venue Managment Tool and add a new entry for the new service which would be 
quite of much effort? Or is there a dynamic way where the Venue Managament 
Tool adapts on existing services? The same seems to apply for the 
capability. If I add a new one I have to change quite a lot of code through 
out the whole AG.

Another question is about what I have to obbey considering the 
streamsDescription creation as well as the setting of the streamDescription 
if I can influence them at all.

Thanks so far.
