Brad,  You might have seen this from an earlier post, but I covered
some of these options here:

For streaming there are a couple solutions:
1) Flash Video:

2) VLC

Hope that helps.  By the way, I've used the Flash Video way, but a
couple problems: 1) the results seems to have a gamma problem (too
dark) that I don't know how to correct in ffmpeg, and 2) You need a
seperate process to transcode to .flv format.
