[libbluray-devel] "Infinite loop" when using menus

[Hugo Beauzée-Luyssen]

Hi,

I'm trying to find the reason for an issue, but I'm way too new to
libbluray to solve it on my own...
The problem raises using the 5th element bluray, I didn't encounter
this on any other disk.
When triggering menus, libbluray stays stuck on two planes, rendering
the same button forever.

Here is a sample from the logs:

libbluray/decoders/graphics_controller.c:255:
_find_selected_button_id() -> default #0
libbluray/decoders/graphics_controller.c:778: rendering page #0 using
palette #0. page has 1 bogs
libbluray/decoders/graphics_controller.c:809:    auto-activate #0
libbluray/decoders/graphics_controller.c:726: render button #0 using
object #0 at 10,10 10x10
libbluray/decoders/graphics_controller.c:960:
_set_button_page(0xa0010000): page flag 1, id 1, effects 0   button
flag 1, id 0
libbluray/decoders/graphics_controller.c:255:
_find_selected_button_id() -> default #0
libbluray/decoders/graphics_controller.c:778: rendering page #1 using
palette #1. page has 1 bogs
libbluray/decoders/graphics_controller.c:816:    auto-activate #0 not
triggered (!cmds)
libbluray/decoders/graphics_controller.c:726: render button #0 using
object #0 at 10,10 10x10
libbluray/decoders/graphics_controller.c:1073:
_update_selected_button(): currently enabled button is #0
libbluray/decoders/graphics_controller.c:778: rendering page #1 using
palette #1. page has 1 bogs
libbluray/decoders/graphics_controller.c:809:    auto-activate #0
libbluray/decoders/graphics_controller.c:698: skipping already
rendered button #0 (object #0 at 10,10 10x10)
libbluray/decoders/graphics_controller.c:960:
_set_button_page(0xa0000000): page flag 1, id 0, effects 0   button
flag 1, id 0
libbluray/decoders/graphics_controller.c:255:
_find_selected_button_id() -> default #0
libbluray/decoders/graphics_controller.c:778: rendering page #0 using
palette #0. page has 1 bogs
libbluray/decoders/graphics_controller.c:816:    auto-activate #0 not
triggered (!cmds)
libbluray/decoders/graphics_controller.c:726: render button #0 using
object #0 at 10,10 10x10
libbluray/decoders/graphics_controller.c:1073:
_update_selected_button(): currently enabled button is #0
libbluray/decoders/graphics_controller.c:778: rendering page #0 using
palette #0. page has 1 bogs
libbluray/decoders/graphics_controller.c:809:    auto-activate #0
libbluray/decoders/graphics_controller.c:698: skipping already
rendered button #0 (object #0 at 10,10 10x10)
libbluray/decoders/graphics_controller.c:960:
_set_button_page(0xa0010000): page flag 1, id 1, effects 0   button
flag 1, id 0
libbluray/decoders/graphics_controller.c:255:
_find_selected_button_id() -> default #0

At this point, the output will be the same forever, one time the page
id is 0, the other it is 1.
I guess this is not enough to debug it without the disk, but feel free
to ask for more information!
If you have any hint so I can try to fix the bug, I'd love to hear it!

Best regards,
