buffered camera feed



Howdy List,
So I am writing some code to take a camera feed from a Mac (off an iSight)
encode to h.264 and feed it out over the network to multiple clients. I am thinking
that, design wise, I want to take an uncompressed video feed append it to an open file
that is mmaped into memory and then have something else pull each frame off the front
on the file, encode it and feed it out to the clients. However after going to the quicktime api
documentation and much else besides on developer.apple.com I am thinking this is
not really possible within the constraints of the Carbon/Quicktime API. At least not the way
I am thinking.


    1. Is this a brain damaged way to go about doing what I want to?
    2. If not what do I need to read to figure how to do it?

I realize that I could use a QTSS but I, for a number of reasons don't want to. If I had my
way I would prefer the uncompressed video/audio data to go into an in memory buffer
until it is quickly encoded and sent out but all the examples I could find on the site show
video data getting saved to a file or sent, uncompressed, to a window on a local client.
Maybe I am missed the directory with all the good examples? Thanks list.


    Fred
