[PATCH] consuming all memory when scanning dvd "Up"
by John Stebbins 09 Dec '12

09 Dec '12

First a disclaimer. This is a big invasive patch. If you don't like it, my feelings won't be hurt. I will be using it in HandBrake. So if you see problems with it, please let me know. Many dvd's are showing up that have titles that have numerous repeated language unit tables and pgc's. The new release "Up" is an example. I believe "Dark Knight" also exhibits this. When scanning such discs with lsdvd (and other programs that scan all titles), libdvdread will consume many GB of data for these repeated elements and gets very slow (e.g hours to read all titles) on OS X due to reading the duplicate data from uncached raw devices. This patch detects duplicates and reference counts pgc's and pgcit's. When a duplicate is detected, a reference count is incremented instead of allocating new memory and re-reading the data. I opted for reference counting instead of simply returning a failure on duplicate detection because it is perfectly valid to have a title with such duplicates. I could easily imagine titles adding duplicates, then navigating around them.

cross/mingw compilation (was assertion failure with certain DVD's)

I'm a bit lost, as is evident. though I can work around it for now. This actually makes me wonder how anybody is compiling it for their windows distros today. I know mplayer just uses the src directory and its own configs (which work), dunno about VLC/others. It seems like both msys and cross compiling don't work, or can somebody give me an example of how they do work, somehow? > ./msvc/config.h:#define HAVE_DLFCN_H 1 > > And it is assumed to exist (is this file made for Visual Studio?) I guess so, since it's under the msvc dir. >> Also as a note when it runs strip and ranlib, if it's being cross >> compiled, it would be helpful to call their equivalent: >> $ ./configure2 --cc=i586-mingw32msvc-gcc >> should eventually call i586-mingw32msvc-ranlib >> >> maybe it could use a new configure option for a prefix or what not. > > ./configure --host=i586-mingw32-msvc should work Yes I think it needs an option like that added (configure2 doesn't appear to have one as of yet). -roger-

[PATCHES] libdvdread and libdvdnav patches
by Ganael LAPLANCHE 30 Apr '12

30 Apr '12

Hi team, First of all, thanks for your great work :) I am the maintainer of FreeBSD ports of libdvdread and libdvdnav and have small patches that you might be interested in, see : For libdvdread : * http://www.freebsd.org/cgi/cvsweb.cgi/~checkout~/ports/multimedia/libdvdrea… This first patch adds support for libdatadir option, fixes incdir option and bigendian detection. Some chunks are FreeBSD-only an can be skipped (PREFIX comment, TMPD modification). * http://www.freebsd.org/cgi/cvsweb.cgi/~checkout~/ports/multimedia/libdvdrea… This patch uses config.h instead of trying to re-detect endianness. For libdvdnav : * http://www.freebsd.org/cgi/cvsweb.cgi/~checkout~/ports/multimedia/libdvdnav… This patch adds support for libdatadir option and bigendian detection. Some chunks are still FreeBSD-only an can be skipped (PREFIX comment, TMPD).

[PATCH] Fix mount point -> device name on OSX
by Rafaël Carré 20 Apr '12

getfsent() only returns '/' entry on my system (10.8) I only have 10.7 around to test, but this bug was reported ages ago: https://trac.videolan.org/vlc/ticket/4069 I don't have a BSD, so I can't test it on BSD too but I don't see why this code couldn't be shared on all BSD.

Libdvdnav and assertion in set_PPT() triggered

I'm using Gentoo and have filed a bug on this issue, thought I'd get another opinion. Using Totem 3.2.1 with gstreamer 10.35; gst-plugins-resindvd 10.22 and libdvdnav 4.2.0 and keep getting this error and Totem crashes. This is happening on 64 and 32 bit systems.
