playback of live HDV stream

Hi,

I want to stream the video (and audio) from 3 HDV camera's to 1 (or
possibly several pc's). Today I tried a very simple "proof of concept",
using
dvgrab -f hdv - | nc -u 10.8.2.240 4090

and
then opening "vlc udp://@:4090"
or "nc -l -u -p 4090  | mplayer -"

This works, but the delay is around 3 to 5 seconds.
The primary goal of these live images would be so a "director" can
direct (with an intercom system) the camera operators. Obviously a lower
delay would be preferred.

Are there any buffers in dvgrab (when used with mpeg 2 TS from HDV) that
might cause a significant delay (and aren't strictly necessary)?
I see the -buffers option wich defaults to 100 "frames", these frames,
are it video frames, or firewire packets, or something else?


yours sincerely,

Tom Mercelis
