[libbluray-devel] Commit b71fe5d9393a31e3d7e8f1d4523a6bf048da11cf causes breakage in BD-J menu

Fri Jun 9 15:40:58 CEST 2017

 The Blu-ray disc rip is on my hard drive, but it's not an iso file. It
contains all the standard folders/files all Full Disc Blu-ray rips are
supposed to have (such as BDMV and STREAM).  I select Top Menu from the VLC
GUI (after selecting Title 1 from either command line or the GUI). There
are times Title 1 (which contains movie advertisements) fails to start
playing at all which means I have to select it again (from either command
line or GUI). After Title 1 starts playing, I right-click and go to
Playback->Title->Top Menu (I can't select Top Menu directly from the menu
offered by Title 1 because the arrow/enter buttons don't respond). And, of
course, as I mentioned in my very first email, once Top Menu starts
playing, the arrow/enter buttons don't respond, so I can't select anything
from Top Menu. I see these Timestamp errors: "
 [000000088521b3d0] core decoder error: Timestamp conversion failed (delay
300000, buffering 100000, bound 9000000)
[000000088521b3d0] core decoder error: Could not convert timestamp
1497009691918941 for FFmpeg
[000000088521b3d0] core decoder warning: early picture skipped
[0000000888a7b450] core video output warning: picture is too late to be
displayed (missing 21 ms)
[000000088521b3d0] core decoder error: Timestamp conversion failed (delay
300000, buffering 100000, bound 9000000)
[000000088521b3d0] core decoder error: Could not convert timestamp
1497009691960641 for FFmpeg". The arrow/enter buttons never start
responding no matter how much time passes.
 Speaking of Title 0 (it doesn't contain anything important except for the
music/Fox logo that you often hear/see when movies start), I can only play
it when I apply libbluray commits that prevent me from using the
arrow/enter buttons in Title 1 menu/Top Menu. But once I apply the commits
that allow me to use the arrow/enter buttons, the opposite thing happens:
Title 0 is not playable (no matter how many times I attempt to play it).
