Actually I had taken note of your previous message. However since you had
said I could use
"testMPEG1or2AudioVideoStreamer" as well as the "vobStreamer" (since the
file has no audio and is
therefore a mpeg2 program stream file), I figured it should work with the
former streamer. And in reality it did work (kind of), except it had the
problem as mentioned above.
The video would play on the client end for 1-2sec, freeze for about 2 min,
and then begin to play again.
In addition to this, I tried other genuine video elementary files using
encountered the exact same problem. I just don't have the permission to
give you access to those files.
However I figured since I am having the same problem with the above
vob/(mpeg2 ps) file, then if you could
help me find the problem with this file, I could just apply it to the other
ones and hopefully come up with
a solution. I hope you understand; I realize the easy thing for both of us
would be for me to just give you
access to the real mpeg-2 es files I'm dealing with, but I can't. So if you
can work with me here, I'd
appreciate it. Also, another important point is that when I was streaming
back to my computer in a loop,
every one of the files worked, even the above VOB file with
"testMPEG1or2AudioVideoStreamer". So I don't
believe it's the type of the file that's the problem. Give me your input
