segmentation fault (core dumped)

Problem Description

Encoding 2160p to 1080p movie ends for most files in a segmentation fault (core dumped). I

Activity Log, Crash Log or any other details

No logging. The encode-logging stops at a certain point.
Latest lines contain:"sync: chapter xx (xx) at frame .... time ...."
Is there any way to get a (much) more detailed logging?

What Operating System are you running?

Arch LTS 6.1.62

What version of HandBrake are you running?

1.6.1-3

Where did you download HandBrake from?

aur of Arch

[sr55]

We would still ned the full log to get context of what your doing.

[MrHappy]

@sr55 Activitylog attached Activity.log

[galad87]

There isn't much we can use in there unfortunately. I wonder if Linux stores better crash logs somewhere. Anyway, how much RAM do you have on that computer? Maybe HandBrake is being killed by OOM or something like that.

[MrHappy]

There 8GB of memory. Running journalctl -r | grep segfault returned this ghb[591120]: segfault at 0 ip 000055edb43ff4a4 sp 00007f40e7ff67c0 error 4 in ghb[55edb2b81000+29e2000]

[jstebbins]

The version of HandBrake being run appears to be from an ArchLinux package. Are there any known problems with how Arch packages HandBrake? They are not currently listed in the Broken Third-Party Builds section of the documentation.

[MrHappy]

Converting a 1080p movie gives no issues. I just removed Handbrake, removed all remaining data en reinstalled it. Now running a conversion of a UHD movie to see if that makes any difference. Only change I have in the preset is 'PictureColorspacePreset: bt709'. When there is any news I will change this comment.

--edit It gave another segfault. Same movie, same preset fails with 'PictureColorspacePreset: bt709' set. Runs fine without PictureColorspacePreset set.

[sr55]

Same problem with the official builds? Arch builds are 3rd party.

I have been having the same issue on handbrake 1.6.1 and now handbrake 1.7. Ram usage is never over 50% . CPU temps are low around 70. I am using the flathub release.

Unfortunately that's not helpful. Can you post the activity log? 1.6 introduced zscale, and the colorspace filter uses zscale too, it would be interesting trying a build with zscale disabled. Does your CPU support avx512?

CPU does not support AVX512.

[snake3ca]

Any video that fails will usually convert on 2nd attempt. Converting the same videos using FFMPEG never fails.

[galad87]

Can you try without the scale & crop?

[snake3ca]

Next time I get a failure I will try without scale & crop.

[snake3ca]

I tested without scale & crop and it still crashes on occasion.

[jmfergeau]

Hi. I don't know if it's related but i'm having the exact same error after some upgrades on my system (arch linux, installed via their package repo. The flatpak version works fine).

Rebooting didn't do anything. Neither downgrading from 1.7.3 to 1.7.2

Here's what I got with gdb :

Thread 1 "ghb" received signal SIGSEGV, Segmentation fault.
0x00007ffff7cb9dc7 in g_menu_exporter_menu_free (menu=0x0) at ../glib/gio/gmenuexporter.c:121

[jmfergeau]

After inspection, it seems the fault comes from appmenu-gtk-module. If this package is not installed, handbrake will report a Failed to load module "appmenu-gtk-module" but will still work as intended.

[MothWaves]

@jmfergeau's solution also applies to liferea, so this seems to be a third-party issue, either with the Arch packagers or appmenu-gtk-module.
