Hi! If I point VLC at

  rtsp://stream.tn.com.ar/live/tnmovil3

Or whatever live stream [0] proposes at a certain time (the browser asks for
permission to launch an external app and VLC is used) I consistently
suffer from PC hangs. Sometimes a few minutes are displayed but at some point
the PC hangs, leaving no possibility to use neither keyboard nor mouse.

I have tried running it in both KDE's Plasma 5 and fluxbox with the same
end result.

I have also tried it in two machines, both amd64 running sid, one with an ATi
video card and the other with an Intel one.

I have not tried to ssh to the machine while this happens.

As a different issue, the video quality is far from ideal, the problem
happening both on my machines and my android-based phone.

If in my phone I use something else than VLC the quality is far superior.


Kinds regards, Lisandro.

Or even Plasma 5's Dragon Player.

reassign 807604 xserver-xorg-video-radeon
thanks

The bug was not in VLC itself, so I'm reassign it.

X maintainers: the bug is the radeon driver crashing when VLC
is pointed to a specific stream, present in the original bug report.

Please do not heasitate to ask for more details as you see suitable.
I'll ad more info in a couple of minutes.
