Kevin,

I was thinking along the lines of your so called "hack",

how was the latency?
Was the IP Camera able to tunnel through firewalls (HTTP)
Any security features on the IP Camera?

Stefan,

Thanks for your comments, yes most IP Cameras are Jpeg streams. Some of
the higher end ones do support MPEG4 and ffmpeg supports live MPG to FLV
conversion (I have not tried and am weary of the latency).

My situation might not even work well with IP Cameras because of
firewall constraints, so I might go with a small itx computer that
starts a Flash Application on startup and sends the signal to the
appropriate server, again my fear would be that a 800Mhz - 1.5Mhz CPU
might not be enough to do the encoding. I am relatively new to the FMS
and Flash Player video streaming, is it possible to get good quality
(around 512Kb) encoded video out of a 800Mhz - 1.5Mhz CPU?
