Hi, I'm seeing a segmentation fault when running transcode on fedora 10.
uname -a Linux 2.6.27.12-170.2.5.fc10.x86_64 #1 SMP Wed Jan 21 01:33:24 EST 2009 x86_64 x86_64 x86_64 GNU/Linux I was using the latest shipped binaries for fedora 10, but downloaded the latest 1.1.0 version and compiled this and tried it too. The debug content is therefore for 1.1.0 The segfault is actually occuring in selinux. Having search the web, I found this: https://bugzilla.redhat.com/show_bug.cgi?id=484595 which is very similar to the failure I'm seeing. This is the command I ran, although I tried xvid as well and saw a similar failure. transcode -H 10 -a 0 -x vob,null -i /home/jmr/dvdrip-data/battlestar-gallactica-season1-disk3/vob/012 -w 900,50 -F mpeg4 -b 128,0,2 --a52_drc_off -f 25.00 -Y 40,0,40,0 -B 36,26,8 -R 1 -y ffmpeg,null -o /dev/null transcode v1.1.0 (C) 2001-2003 Thomas Oestreich, 2003-2009 Transcode Team libdvdread: Using libdvdcss version 1.2.10 for DVD access libdvdread: Couldn't find device name. libdvdnav:DVDOpenFilePath:findDVDFile /VIDEO_TS/VIDEO_TS.IFO failed libdvdnav:DVDOpenFilePath:findDVDFile /VIDEO_TS/VIDEO_TS.BUP failed libdvdread: Can't open file VIDEO_TS.IFO. libdvdread: Using libdvdcss version 1.2.10 for DVD access libdvdread: Couldn't find device name. libdvdnav:DVDOpenFilePath:findDVDFile /VIDEO_TS/VIDEO_TS.IFO failed libdvdnav:DVDOpenFilePath:findDVDFile /VIDEO_TS/VIDEO_TS.BUP failed libdvdread: Can't open file VIDEO_TS.IFO.
