[vlc] Some problem with livedotcom mux/demux

Wed May 19 10:44:45 CEST 2004

Hi vlc list,

Before all i would like thanks all developers for this very great piece of 
software.

I am currently using vlc-0.7.2-test3 on gentoo box. And i have the following 
problem.

I try to do this. 
On server side i run this

 vlc -vvv /home/philippe/stream/Geant/VTS_ 01_01.VOB --sout 
#rtp{dst=233.10.51.251,port=1234,sdp=http://mcast-server.belnet.be:8080/test.sd
p} --loop --ttl 255 --mtu=1400

And on the client side i get these error message .

This result on strange visualization issue where it seem that there is some 
time discontinuity.

When i take the same file but send it with the following command line 

/usr/bin/vlc -vv --intf 
dummy /home/philippe/stream/Geant/VTS_01_1.VOB /home/philippe/stream/Geant/VTS_01_2.VOB 
--sout rtp://23
3.10.51.252 --ttl 255 --loop --sout-standard-mux=ts --sout-keep

I don't have any discontinuity and don't have any strange visual effect. The 
stream is "fluid".

I have also noted that i  have this problem with VOB file but not with mp4 
file.

How i can resolved this ?  any help are welcome.

Thanks 

Philippe.
