Package: vlc Version: 2.2.1-1~deb8u1 Severity: normal Tags: patch We run VLC as a daemon to transcode an MJPEG stream from a StarDot camera and pipe it into another program. After upgrading from wheezy to jessie, VLC began to crash with SIGFPE.
Although the root cause may be elsewhere in VLC, the patch at https://patches.videolan.org/patch/10246/ resolves the problem. This report in the OpenSUSE Bugzilla is probably the same problem: https://bugzilla.opensuse.org/show_bug.cgi?id=978282 Details on my installation: VLC is invoked as follows: /usr/bin/vlc -I dummy --repeat --sout-keep --http-reconnect http://ip-redacted/nph-mjpeg.cgi --sout '#transcode{venc=x264{keyint=60,profile=baseline,level=3.0,nocabac},vcodec=x264,vb=500,scale=1,acodec=none,threads=6}:rtp{dst=127.0.0.1,port=10000,mux=ts}' --syslog Data from core dump: $ gdb /usr/bin/vlc ~/core GNU gdb (Debian 7.7.1+dfsg-5) 7.7.1 Copyright (C) 2014 Free Software Foundation, Inc.
