[Live-devel] RTP/H264 low latency streaming + source change

[Stéphane SARAGAGLIA]

Hi all,

I am using Live555 libraries to stream H264 video provided by a frame 
grabber, via RTP (not RTSP).
I use VLC and VLC activeX as a RTP/H264 client.

Sometimes, I need to change the camera used by the framegrabber, so I 
close the RTP sink, the framer, the source, and I open them again with 
the new video. Doing that, (even with the same video parameters), the 
client often hang (but not every time), and sometimes go on playing 
again but with a big delay.
How can I prevent the client from freezing the video or display the 
video with delay ? Sending some missing frames ? Special trick to warn 
client ?
My main objective is LOW latency, some image skips are not a problem.

Any advice ?
(client cannot send data to server, so no rtcp)

Regards
