[PD] VLC 2.1.x and Gem

[Csaba Láng]

Hi Etienne,
I am not sure if I understood well your problem, but I have a strange
behaving in Gem too with VLC plugin. I have 2 identical IP cams on a local
network, and while the first cam streams video smoothly or almost smoothly,
the other cam shows a one second stream max or less, than stops at the last
frame and never goes on.
Already tried many computers with ubuntu 14.04.2 and looks the same. While
in a browser or VLC i can see the stream, in Gem with videovlc plugin it
stops.

Here are some error reports from the terminal, maybe it is interesting for
you:

MultiFramedRTPSource::doGetNextFrame1(): The total received frame size
exceeds the client's buffer size (100000).  80761 bytes of trailing data
will be dropped!
../../../include/vlc_xlib.h:46:vlc_xlib_init: Xlib not initialized for
threads.
This process is probably using LibVLC incorrectly.
Pass "--no-xlib" to libvlc_new() to fix this.
