[Live-devel] Problem streaming a live H.264 stream to VLC

[Brett Granger]

The numbers in parentheses are a measure of "how late" the picture was 
received relative to when VLC calculated it should be displayed.  I 
believe the resolution is microseconds, so 250000 is .25 seconds late. 
Seems like you might have a problem with your presentation times? 
Unfortunately, that's about as much help as I can offer...

Good luck,
