[Live-devel] Can this be done reasonably?

[Neil Alexander]

Hello All,

I hesitate to ask, but here goes:

I have attempted to use the QuickTime Streaming API without success. I 
was able to go a certain distance, but unfortunately, all the 
requirements could not be met. Here are those requirements:

1) Base platform to send from is Mac OSX 10.3+
2) I would like to send RTSP compliant feeds.
3) > 1 simultaneous feed (multiple .sdp files)
4) I need to overlay information on each video feed (frame count, 
clock, whatever)
5) Full control over camera frame rate and resolution.

With QuickTime Broadcast API, I could do all except #4. Unfortunately 
this requirement is not negotiable.

Using the RTP components within QuickTime appear possible, but quite 
involved.

I am just beginning to look at Live.com's stuff. Several things are not 
clear.

OS-X support seems to be secondary.
How the heck do I view a stream from the samples? All are command lines 
and don't appear to have any gui attached.
Are there any Xcode/Project Builder projects? Coming from the GUI 
world, doing command line building is somewhat alien (though I'm 
willing to try).
Does the requirements list above seem reasonable to do from Live?
Is it necessary or easier to use the Darwin injector stuff, or can I 
avoid using the QTSS?

Any help on this decision would be appreciated. I've burned a lot of 
time on QuickTime, and I am quite frustrated at the lack of 
documentation and help. The QTSS list is pretty much dead, and no 
responses to my queries - or most other people's queries, either.

Thanks!
