dvdnav_describe_title_chapters crashes
Hello everyone, We seem to have a bit of an issue with dvdnav_describe_title_chapters. This function is the biggest crash of VLC, by quite a bit (followed by a crash in dvdnav_menu_call -> play_Cell, but that is a different story). Which is a bit odd, since DVD is probably not the biggest use of VLC... So far, we do not have a complete backtrace (because our last build did not have all debug symbols for dvdnav), but we will. In the meantime, we were wondering if anyone else was seeing such a high level of crashes in this function or are we the only ones seeing those? We use the latest release of dvdnav, aka 4.2.0, unpatched. Best regards, -- Jean-Baptiste Kempf http://www.jbkempf.com/ - +33 672 704 734 Sent from my Electronic Device

Any idea which dvd's?
Abolutely not. Those are EIP and register traces sent by VLC at crash-time. I guess Erik's branch would help, though... Best regards, -- Jean-Baptiste Kempf http://www.jbkempf.com/ - +33 672 704 734 Sent from my Electronic Device

Quoting http://lists.mplayerhq.hu/pipermail/dvdnav-discuss/2012-July/001726.html: | With some of those copies I can trigger at least four different | crashes in libdvdnav 4.2.0's dvdnav_describe_title_chapters(), | that aren't triggered when ripping with zero padding which lets | VLC rejects the disc right away. The last part isn't actually correct, though, at least one of them can be triggered with the original DVD. All the issues are fixed in Erik's repository and I haven't seen any additional crashes in dvdnav_describe_title_chapters() so far. Fabian
