Can't watch DVD

Hi I bought a new DVD, but can't watch it. Using libdvdread 4.2.0 lsdvd eats a lot of memory and gives the following messages: $ lsdvd libdvdread: Using libdvdcss version 1.2.13 for DVD access *** libdvdread: CHECK_VALUE failed in ifo_read.c:1251 *** *** for vts_ptt_srpt->title[i].ptt[j].pgn != 0 *** *** libdvdread: CHECK_VALUE failed in ifo_read.c:1980 *** *** for pgci_ut->nr_of_lus < 100 *** Please send bug report - no VTS_TMAPT ?? *** libdvdread: CHECK_VALUE failed in ifo_read.c:1251 *** *** for vts_ptt_srpt->title[i].ptt[j].pgn != 0 *** *** libdvdread: CHECK_VALUE failed in ifo_read.c:1980 *** *** for pgci_ut->nr_of_lus < 100 *** Please send bug report - no VTS_TMAPT ?? *** libdvdread: CHECK_VALUE failed in ifo_read.c:1251 *** *** for vts_ptt_srpt->title[i].ptt[j].pgn != 0 *** With a more recent version from git it doesn't use that much memory and outputs just: $ lsdvd *** libdvdread: CHECK_VALUE failed in ifo_read.c:1246 *** *** for vts_ptt_srpt->title[i].ptt[j].pgn != 0 *** *** libdvdread: CHECK_VALUE failed in ifo_read.c:1246 *** *** for vts_ptt_srpt->title[i].ptt[j].pgn != 0 *** libdvdread: Invalid IFO for title 2 (VTS_02_0.BU). Can't open ifo 2! And mplayer produces: Playing dvd://2. There are 99 titles on this DVD. There are 1 angles in this DVD title. *** libdvdread: CHECK_VALUE failed in ifo_read.c:1246 *** *** for vts_ptt_srpt->title[i].ptt[j].pgn != 0 *** *** libdvdread: CHECK_VALUE failed in ifo_read.c:1246 *** *** for vts_ptt_srpt->title[i].ptt[j].pgn != 0 *** libdvdread: Invalid IFO for title 2 (VTS_02_0.BU). Cannot open the IFO file for DVD title 2. No stream found to handle url dvd://2 I tried it on different computers, so it is not a hardware problem. Only one Window Media Player could actually play it. Any help would be appreciated. Jan

[PATCH] Initialize dvd_reader_t struct in DVDOpenImageFile
by Richard Hulme 02 Mar '14

02 Mar '14

Hi, This is a patch I found in MythTV's copy of libdvdread that seems like it could/should be upstream too. It ensures that the dvd_reader_t struct is initialized (e.g. the css_state field is currently undefined if 'have_css' is false). The patch is part of a bigger MythTV-specific change by Chris Pinkham: https://github.com/MythTV/mythtv/commit/3af3489 Richard Hulme

New release
by Timothy Gu 13 Feb '14

13 Feb '14

Hi all, It's quite some time before the last release. There are some critical security fixes in SVN now. I guess it should be time for a new release. Also, if possible, can someone back port changes in the VideoLAN's fork to the official one? Thanks. Timothy

Possible libdvdnav related crash

Hello, I was trying to play a DVD in two different apps and as soon as I pressed play both of them crashed. I reported the crash to one of the program's bug tracker and was redirected here. https://bugs.kde.org/show_bug.cgi?id=330475 libdvdnav part of the backtrace: Thread 2 (Thread 0xaceffb40 (LWP 6877)): [KCrash Handler] #7 0xb77ab424 in __kernel_vsyscall () #8 0xb5bfdaff in raise () from /lib/i386-linux-gnu/libc.so.6 #9 0xb5c01083 in abort () from /lib/i386-linux-gnu/libc.so.6 #10 0xb5bf6857 in ??

I'll retest with mplayer today. -- Best regards, karaluh
