Answer 1

I'm a little confused here... do you want to upload a
pre-recorded video file, or have a live broadcast (like from a
webcam?)
If it's live broadcast, you'll want to use FMS.
If it's a prerecroded video, FMS might be a bit of expensive
overkill. You could just as easily use PHP to begin playing the
video from a given byte (see

)
