<DIV><FONT face=Arial size=2>A version of this message was originally sent to
the list on March 11, but generated no response. I really need some
assistance...please?</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Greetings,</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I have installed VLC 0.7.0 (downloaded from
videolan.org a couple of days ago) on two Via C3 systems running Fedora Core
1. The two systems are connected together through a 100Mbs ethernet hub
with no other systems connected.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>On the system designated "server", there is a video
camera connected through a v4l-compatible (bt878) card. Audio input is
through the mic input and/or the Line input (two different
microphones).</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>The command: "vlc
v4l:/dev/video0:norm=ntsc:channel=1" works as expected...video is displayed on
the local screen.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Next I wanted to send the video stream to the
second (client) system.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I executed the command: "vlc -vvv
v4l:/dev/video0:channel=1:norm=ntsc --sout udp://192.168.0.2" on the server
system (based on the VLC HowTo)</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>The command: "vlc -vvv udp:" was then executed on
the client system.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Unfortunately, the server vlc system does not seem
to be able to send anything to the client vlc system. The -vvv outputs of
both systems are attached.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>On the server side, I note that the /dev/video0
device is reported as busy. I know of nothing else that would be using the
video resources at that time. The server messages also indicate some
problems with the packetizer. I have no idea what would cause that or how
to cure it.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>The -vvv output on the server side begins like
this:</FONT></DIV>
