[vlc] Re: Network stream freezes after a few sec

Dermot,

You are right to ask all these questions. They may help me
figure out if I am doing something wrong.

It is a MPEG-PS file encoded at 6Mbps. It plays perfectly when
played locally.

The two PCs are connected through a 100 Mbps Ethernet hub. No other
PCs are connected to this hub.

TCP/IP is not involved in this particular setup. The network cards are
hooked up USB 2.0 and I am using a serial USB driver to pick up packets
from the network and pass them on to vlc. I have an application that
gets the packets and uses 'fwrite' to write to a pipe that feeds that 
data to vlc via stdin. I hope that makes sense.

I want to try and see if buffering a couple of seconds of data in
vlc makes things better. Is there a way to enable buffering via
the command line?

I agree. I think using the right combination of all the options
vlc has will probably solve the problem. I just to find which ones
will help.

Thanks,
