Segmentation fault

[Lukasz]

Hi

I am trying to multicast DVB but Segmentation fault occurs.

I am using that command line:
vlc -vvv dvb:// :dvb-adapter=0 :dvb-frequency=498000000 :dvb-srate=27500000 :dvb-caching=300 :dvb-device=0 :dvb-inversion=2 :dvb-probe :no-dvb-budget-mode :dvb-satno=0 :dvb-voltage=13 :no-dvb-high-voltage :dvb-tone=-1 :dvb-fec=9 :dvb-lnb-lof1=0 :dvb-lnb-lof2=0 :dvb-lnb-slof=0 :dvb-modulation=64 :dvb-code-rate-hp=2 :dvb-code-rate-lp=1 :dvb-bandwidth=8 :dvb-guard=8 :dvb-transmission=8 :dvb-hierarchy=-1 --sout '#duplicate{dst= standard{access=udp,mux=ts,url=239.252.90.1,sap,name="TestStream"}}'

after that I have

Segmentation fault


I use gdb and the backtrace is

Previous frame inner to this frame (corrupt stack?)


Does anybody has a idea what is happening??Help me, please.

Thank you in advance

could you compile VLC with --enable-debug ? (this would make the backtrace info usable)
