All things related to multicast

[Frank Fulchiero <>]

Having figured out enough about the run and shoot hardware to stay  
out of trouble most of the time, I want to test considerable  
configurations of software-based live multicasting.

Right now, using Wirecast on a Mac Mini, with QTSS on an XServe.

The current test matrix is:

1. Using Wirecast as encoder and multicast server, MPEG4 simple  
profile video, AAC audio, the current test

In VLC, open network, HTTP> http://136.244.12.62/mc/mini1.sdp

in QT Player, File Open URL, same as above or
http://136.244.12.62/mc/mini1.mov

2. Using Wirecast as encoder and multicast server, H264 video, AAC audio

3. Using Wirecast as encoder, unicasting to QTSS which reflects to  
multicast, MPEG4 simple profile video, AAC audio

4. Using Wirecast as encoder, unicasting to QTSS which reflects to  
multicast, H264 video, AAC audio

I will be using lower bandwidth streams, 500-600 kbps, as I am more  
interested in network connectivity and format/platform compatibility  
than visual quality, which will come along later.

Clients to be tested are VLC on both Mac and PC, and QT Player on  
both Mac and PC. Though Wirecast can encode several live streams at  
once, I think I will stick to one at a time initially, to minimize  
variables.

I don't want to make a complete nuisance of myself, and also belong  
to the QTSS Apple list, and the wg-rc Research Channel Working Group.
This wg-multicast groups is probably the most experienced with  
multicast technology, and probably should not suffer my upcoming  
simple test requests (which can always be ignored).

Anyone have any ideas as to how I can be the least intrusive? What  
list is most appropriate for requests?
I will not be in a hurry for test feedback,  a 24 hr turnaround is  
fine and everyone gets weekends off.

Appreciate any ideas. Thanks,
