Hello,
I want to use live555ProxyServer for retrieving one back-end RTSP stream and
sending it to multiple RTSP clients. When I have only one client (e.g. VLC), it
is working fine, but when I attach a second client to the proxy-stream,
Problem 1: I can't see the second stream (e.g. in a second VLC instance on a
different PC, although the timer in VLC is counting upwards) Problem 2: on the
first client the frame rate and image quality breaks down
Setup:
I am using this version
#define LIVEMEDIA_LIBRARY_VERSION_STRING "2017.06.04"
#define LIVEMEDIA_LIBRARY_VERSION_INT 1496534400
in proxyServer/live555ProxyServer.cpp I set in line 61
OutPacketBuffer::maxSize = 200000; // bytes
because I receive frames which are above 100000 (and I cannot change this,
however, the problem I described above also occured under the default setting
of 100000).
I started the live555ProxyServer with this command
live555ProxyServer -V rtsp://root:root@192.168.5.245:554/axis-media/media.amp
then I
1. started a VLC client
2. after a few seconds started a second VLC client and could immediately
observe the problem
3. stopped the second VLC client, the first VLC client showed a fluent
picture again
4. stopped the first VLC client
Attached are the logs generated by live555ProxyServer (IPs and credentials were
replaced).
Does somebody have an idea, how I can resolve this problem or what I am doing
wrong here?
Thanks for any help
Martin
