[Live-devel] Strange sequence number

Hi Ross,
I have tried to stream a m4v file from my pc to a virtual machine on the
same pc. 
I have sniffed the packets on the "server side" and I have noticed that
sometimes, before a packet with the Marker-bit, some packets are lost.
It does not happen before every Marker-bit packet but when it happens is
always before this kind of packet.

As I am using a virtual machine as client it would be really unusual
this loss, so I am wondering if it could be a problem of the library.

I have also tried to insert in the half (better on the same machine
where the streamer is located) an rtsp-proxy that is able to save the
packets that receives and I have compared the original file streamed
with the one created by the rtsp-proxy and the files are identical until
the first packet out of sequence and then the original contain more
data, after that the files still be identical so in somewhere these data
are lost.

I attach a file with a cut version of the sniffed log.
