[PATCH] ancient patch for copying palette info
by Roger Pack 12 Nov '11

12 Nov '11

Hello all. Dunno if this is debatable or not, but I found this patch (also attached): http://comments.gmane.org/gmane.comp.video.libdvdnav.devel/66 It didn't fix mplayer's dvdnav subtitle colors, but thought it might be worth examining anyway. Does it have any merit? Thanks! -roger-

Hi Henry, I'm crossposting to dvdnav-discuss list, where you should continue this thread.

Would you be able to provide an ISO image to one of libdvdnav developers to try and fix the issue?

Patch from the Living dead for dvdnav
by Jean-Baptiste Kempf 04 Nov '11

04 Nov '11

Hello, I am super-annoyed, since I have a patch on dvdnav, that I apply on all VLC release, on Windows and Mac OS X, since (at least 2006). I understand absolutely nothing of this obscure patch on this obscure piece of code... It does work quite, but I can't explain it, since it predates my work on the project. I thought I should share it, with you, upstream, as someone could make some sense out of it. With my best (sorry) regards -- Jean-Baptiste Kempf http://www.jbkempf.com/ - +33 672 704 734 Sent from my Electronic Device

strange enum/domain code
by Erik Hovland 02 Nov '11

02 Nov '11

In dvdnav.c there is a few places where an assignment is made. Like at or about line 563: vts_event->new_domain = this->position_next.domain; new_domain is of type dvd_read_domain_t and looks like this: typedef enum { DVD_READ_INFO_FILE, /**< VIDEO_TS.IFO or VTS_XX_0.IFO (title) */ DVD_READ_INFO_BACKUP_FILE, /**< VIDEO_TS.BUP or VTS_XX_0.BUP (title) */ DVD_READ_MENU_VOBS, /**< VIDEO_TS.VOB or VTS_XX_0.VOB (title) */ DVD_READ_TITLE_VOBS /**< VTS_XX_[1-9].VOB (title). All files in the title set are opened and read as a single file. */ } dvd_read_domain_t; While position_next.domain is of type domain_t and looks like this: typedef enum { FP_DOMAIN = 1, VTS_DOMAIN = 2, VMGM_DOMAIN = 4, VTSM_DOMAIN = 8 } domain_t; Note how the two enums only share two distinct values. Do you think that other code elsewhere takes care to make sure that the enums are in sync? I haven't found code for this. I get the domain_t enum. But I have not yet figured out the dvd_read_domain_t enum yet. I am inclined to think that the real error here is that new_domain is the wrong type. Any opinions?
