Dear developers! Probably my question is offtopic but i asked about it 
already in vlc-streaming list.
*What does it mean "late packet for udp input" and what should i do to 
get rid of it?

*Description:
On server :
vlc -vvv gagarin.avi --sout 
'#standard{access=udp,mux=ogg,dst=localhost:1234}'
On client (on the same computer)
vlc -vvv udp:@localhost:1234

On server i get such messages:
[00000327] access_output_udp private debug: late packet for udp input 
(816609)
[00000327] access_output_udp private debug: late packet for udp input 
(816724)
...........................................
[00000327] access_output_udp private debug: late packet for udp input 
(792655)

Client looks like to receive something but i don't see the movie. 
Tcpdump shows that packets are sent:
10:41:25.297811 IP localhost.localdomain.32807 > 
localhost.localdomain.1234: UDP, length 1500
10:41:25.297836 IP localhost.localdomain.32807 > 
localhost.localdomain.1234: UDP, length 1268
10:41:25.648240 IP localhost.localdomain.32807 > 
localhost.localdomain.1234: UDP, length 1500

I tried to change settings by adding something like
 --sout-udp-caching 2000    -  didn't help
 --sout-udp-group  -    didn't help
--sout-udp-raw   -  increased the size of packets to about 4000 and 
client sets MTU=6000
-sout-udp-ttl 4 -  it's clear that it has no influence in this case but 
i tried to add it too

Nothing helped!
