Hi,
I have developed a real-time splicing tool that can
splice real-time mpeg2TS streams.
I use VLC as a client to check the result of the
spliced stream as it is the only one that give good
feedbacks on problems. But now I am facing something
I cant really explain :
I have record a result of a splice using the "Dump
raw input" option of vlc. When I locally play the
file
using VLC, the result is perfect, no display
problem.
Nevertheless, when I send this same file on the
network via VLC on udp/multicast and when I visualise
the sent stream on VLC on another computer, theresult
isnt good at all !! VLC seams to loose frames at the
splicing point.
Let me also mention that the 2 streams are
different (different bitrate) but why would it play
perfectly from file but not when it is send on the
network ??
is vlc behavior different when dealing with files or
network ??
You can try yourself to play the enclosed file in
local and then send it via udp/multicast and see the
result.
here you can download the file :

thanks a lot for any clue and help.
