   There is a NEED for me to find out what frames
(whether I, P or B) is transmitted or received, so if
you don't mind, can you send me the codes and some
instructions? ;)

   The protocol we've ported to is called SCTP. Some
more things I've found out:
   1. Once vlc is connected to vls, a window pops up
in vlc.
   2. Data is transmitted from vls to vlc, but nothing
is shown in the window (all black).
   3. For a video that takes the vlc about 30 sec to
play (from disk), the transmission between vls and vlc
lasts for about 3 min before vls stop sending any
data. Throughout this period, windows remain black.

   With only modifications to socket calls in the
files listed below, I don't quite understand why it
doesn't play the video.

   I've attached the log files of both the vlc and vls
with this mail. Hope that it provides some clues...
