Delays this large are almost always caused by buffering somewhere.  In your 
case, the buffering is probably occurring between the capture/encoding of 
the video, and your call to "popBuffer()".

That's good, because VLC's own buffering is (by default) quite low.

Actually, the "MPEG4VideoStreamFramer" object parses the MPEG-4 stream

>Is this necessary though I have a live stream?

It depends.  If your "popBuffer()" routine returns complete, discrete 
MPEG-4 video frames (one at a time), rather than arbitrary pieces of data, 
then you can use a "MPEG4VideoStreamDiscreteFramer" rather than a 
"MPEG4VideoStreamFramer".  This will reduce a small amount of latency 
(although not nearly enough to explain the 30s that you are seeing).
