Thanks for your answer. The problem is that a GOP ,in
display order, never start with I frame but usually
with a B frame. So VLC receive first an I frame then
the B frame, but reorder it, right ? Can vlc lose a
bit of info ??
The thing is that I did the test, and some very little
artifact appears on the screen, few scares.
My attention is to test my splicing tool with VLC. I
use beginning and end of GOP as splicing points. But
of course I had to try with the exact same stream
first. So i only remove one GOP from the stream and
see VLC's behavior.
You can use my tool to see yourself. Of course, VLC is
so good that I tend to think the problem is in my tool
but I checked everything and I couldn't find any
My tool is build on live555.com library. You can
download my tool from here.
Just compile it and play the "testRelay" file in
testRelay work on command line as follow :
./testRelay <input_multicast_address1> <port1>
(i.e:./testRelay 188.8.131.52 4444 184.108.40.206 4444
to ask splicing, press the key "s", to stop "q"
The splicing tool is in the liveMedia directory :
Thanks so much for helping me.
I want to release a Real Time splicing tool on GPL, if
you want to help me with little thing, please email
me. I would really like having experts helping me.
