[PATCH] UDF2.50 part 1
by Jorgen Lundman 06 Oct '11

06 Oct '11

Separated RAR support, as it is the most questionble change in the old patch. Told emacs to never use tabs too, so it should be cleaner. Add UDF2.50 logic, which includes BD5ISO, and HD-DVD support. Support non-DVD style access. (File iteration, and reading). Diffed against svn 1153. This patch includes: 1. Add ExtFinfo (262) support 2. Add FileType (250) re-direct support 3. DVDOpendir/DVDReaddir/DVDClosedir/DVDOpenFile for UDF access. 4. dvdread-1.9.7 stat methods for obtaining VOB data and sizes 5. AD chaining, instead of assuming files will always fit in 1 AD group. 6. dvd_udf API uses "UDF_FILE" type instead of "starting block number". 7. Separate struct AD and struct FileAD instead of ugly 64->32 bit work. 8. Minor memory clearing problems, and memory leaks.

dvdbackup and the skipping unused/bad sectors patch
by Benjamin Drung 11 Jan '09

11 Jan '09

Hi, Don Mahurin has modified [1] dvdbackup [2] to find and avoid unused blocks by following title set titles, and then skips the unused blocks. The purpose of this modification is to avoid possible bad sectors that sometimes occur, by manufacturer defect or intention, in unused regions of the disc. The titleset titles are followed using libdvdread and "libdvdvm" extracted from libdvdnav. The "libdvdvm" parts are not perfect, as some jump instructions are skipped to avoid the actual execution of the Jump, which fails in this isolated use of the library. It would be nice if this "libdvdnav" could be separated from libdvdnav into a standalone library. In libdvdnav 4.1.3 there is already an directory called vm.

libdvdread and DVDFileStat
by Benjamin Drung 30 Nov '08

30 Nov '08

Hello, dvdbackup [1] uses DVDFileStat exported from dvd_reader.h in libdvdread 0.9.6 [2] and 0.9.7 [3]. But libdvdread 4.1.3 from mplayer does not export this function. Can mplayer sync libdvdread 0.9.7 from ogle or add this function? Regards, Benjamin Drung [1] http://dvdbackup.sourceforge.net/ [2] http://www.dtek.chalmers.se/groups/dvd/olddownloads.shtml [3] http://www.dtek.chalmers.se/groups/dvd/dist/libdvdread-0.9.7.tar.gz

trying to resume without any resume info set
by Bryan Henderson 30 Nov '08

30 Nov '08

I'm using libdvdnav via Mplayer. With the "play" button on a menu selected, I call dvdnav_button_activate() and libdvdnav issues the error message, "trying to resume without any resume info set." I don't know anything about DVD interaction, so I don't know what to do about this. I can understand why resuming might be impossible, since displaying that menu was the first thing the program did; i.e. there's nothing to go back to. But is there supposed to be some resume info set up anyway so that this button causes the main title to start playing? Or is a "resume" command not supposed to be executed here?

[MPlayer] multi-angle DVD crash, dvdangle selection with dvdnav not working
by Dominik 'Rathann' Mierzejewski 23 Nov '08

23 Nov '08

Hi. I have a bug report about MPlayer crashing when playing chapter 2 on a multi-angle DVD (using dvd://N -dvdangle 2 -chapter 2). The reporter is willing to send a physical copy of the DVD to someone who can fix it. Is anyone interested in getting one? He also said he could upload the full ISO image. Another thing he's reporting is that -dvdangle isn't working with dvdnav://. Here's the full bugreport (without a gdb trace so far): http://bugzilla.livna.org/show_bug.cgi?id=2051 Regards, R. -- Fedora http://fedoraproject.org/wiki/User:Rathann RPMFusion http://rpmfusion.org | MPlayer http://mplayerhq.hu "Faith manages." -- Delenn to Lennier in Babylon 5:"Confessions and Lamentations"

dvdread patch for broken dvd's
by jezz＠hkfree.org 23 Nov '08

23 Nov '08

Hi, I have already posted this to mplayer-users mailing list. I have DVD disc with broken UDF structure. I can't play this disc using current libdvdread, because vob for chapter 37 is not found - entry in UDF has tag identifier 262 (Extended Attribute Header Descriptor) instead of 261 (File Entry). ISO 9660 filesystem is correct, so it can be used. When file can't be located with UDF functions, then we can try ISO. This fix conforms with standards and plays my disks :) Patch is created against current svn://svn.mplayerhq.hu/dvdnav/trunk/libdvdread. Any comments are welcome. I will be glad if this commit will be accepted to libdvdread. Regards -- Jezz mail: jezz(a)hkfree.org jabber: jezz(a)njs.netlab.cz

question regarding data coming from libdvdnav
by Sergey 'Jin' Bostandzhyan 23 Nov '08

23 Nov '08

Hi, I have a question regarding data that is coming from libdvdnav. The text below may seem a little off topic, but please stay with me here, I would appreciate any hints regarding this matter :) The reason behind the question is: we observed various problems when feeding the data to players (I'm not talking mplayer or vlc, but hardware players like the DSM-510, PlayStation 3 and others). In our setup the player gets the data from a HTTP server that is embedded into the application, the data comes from a ripped iso, the data is read with the help of libdvdnav. Some players will simply crash after a couple of minutes of play or will immediately refuse to play the stream. Others will play, however with an effect like on the old vinyl records - from time to time parts of the video are being looped. We tried to plug in a transcoder (like vlc, ffmpeg, mencoder) and remux the stream to ts, this seemed to generally enable playback on devices that refused to play the original data, however the success rate was low: the transcoding apps were not handling the on the fly remuxing too well. I only had some success with mencoder, however from time to time it printed messages like: "1 duplicate frame(s)!" or "Skipping frame!" and the "looping effect" could be observed on the player. So, back to the original question: what kind of MPEG comes from libdvdnav? Is there anything "special" about it? Is it normal PS or is it PES? Do you have any idea on what might be causing troubles for the decoding apps? Of course it's difficult to guess why some player with proprietary black box firmware is crashing, but since MPEG2 files encoded in a "normal" way work, it must be something special, related to the data coming from the DVD. To make sure that it is not a bug within my app I tried extracting an mpeg from my test iso using libdvdnav/libdvdread 4.1.3 (this is also the version that I am currently running), I used the "menus" example application that comes with libdvdnav. After ripping the mpeg I tried streaming it with the DSM-510 and it also crashed. The image is CSS-free, so decryption is not involved. My app is an open source UPnP media server, so you guys will make a lot of people happy if you help me to resolve this problem :) Thanks! Kind regards, Jin

Re: [DVDnav-discuss] Using libdvdnav on ARM Based NAS

> are you sure there aren't other versions of libdvd* lying around? The only version I have ever installed on this NAS is 4.1.3. > IIRC arm5 is a 32-bit little endian architecture (although > it can be used as big-endian no-one ever runs it in this mode, right? ). > I don't expect endianness problems; did you try to set some flags > to force the necessary alignment? This is definitely little endian and I am compiling it that way. I'm using a toolchain developed specifically for this device. As far as alignment, I did not find any ARM gcc options for alignment. I did try setting the -mcpu amd -march options and got the same result with the zero check errors.

Using libdvdnav on ARM Based NAS
by John 22 Nov '08

22 Nov '08

Hi, I have compiled libdvdnav 4.1.3 and libdvdread 4.1.3 for my ARM based D-Link DNS-323 NAS (armv5tejl little endian). I had no errors while compiling either library. However, I am getting a lot of errors while running the menus example in libdvdnav. In the menus.c source code, I replaced /dev/dvd with the actual path to my .ISO file.

00104c1656e0000000000000000000000000000 libdvdnav: DVD disk reports itself with Region mask 0x00000000. Regions: 1 2 3 4 5 6 7 8 This ISO is CSS free. I also compiled the same libdvdnav and libdvdread on my Ubuntu Hardy setup and I do not receive any errors while running the menus binary with the same .ISO I used on the DNS-323 NAS. When compiling other code for this NAS, I've seen issues with memory alignment in a couple of different applications. I'm not sure this is the issue here, but I thought I would let you know. Thanks, John
