[Live-devel] Strange sequence number

Luca,

The problem is being caused by the extremely large (in some cases, >100 
kByte) MPEG-4 video frames in your file.  (You must have the worst MPEG-4 
encoder on the planet :-)    You will have already discovered that you need 
to increase "OutPacketBuffer::maxSize" in your server application.

In your client application(s), you will need increase the kernel's socket 
receive buffer size, to properly handle these large frames (which are split 
over many RTP packets, that are sent (and thus received) in immediate 
succession).

The easiest way to do this is to change - in "MultiFramedRTPSource.cpp" - 
the line
         increaseReceiveBufferTo(env, RTPgs->socketNum(), 50*1024);
to
         increaseReceiveBufferTo(env, RTPgs->socketNum(), 200000);
