Ok, so I got it working somewhat. I can play the stream using VLC
(although it stops after 41 seconds for some reason). I found that
Quicktime plays back the entire stream without any problems. However,
with both players, the audio is no in sync with the video. Not sure why
this is, I'm sure there is something I am missing here. Looking at the
wireshark capture of the network stream, I can see that the timestamps
on the two streams do not match up. Does that have something to do with
it?
I have attached my test program.
Again, any help on this subject is greatly appreciated.
