[SOLVED] MPV crashes with SIGSERV when playing specific mp3 files - troubleshooting guidance needed | Arch Linux Community | Page 1

The issue doesn't happen with all files. Only a subset. If I play the same files with mplayer, they play fine. Making a post here to see if anyone can help me troubleshoot before I go on to make a github issue or something. I can't really see any obvious errors in the log, so I am pretty confused.

> mpv foo.mp3 
● Audio  --aid=1  (mp3 1ch 44100 Hz 67 kbps)
AO: [pipewire] 44100Hz mono 1ch floatp
fish: Job 1, 'mpv foo.mp3' terminated by signal SIGSEGV (Address boundary error)

Modded permissions to 777 to try to avoid that contingency.

@clever cedar does that mp3 work on vlc?

clever cedar Mar 12, 2025, 6:58 PM

worthy nymph <@532113204051050496> does that mp3 work on vlc?

yes. it works fine with vlc/mplayer.

@clever cedar does it work in mpv-git?

clever cedar Mar 12, 2025, 7:05 PM

worthy nymph <@532113204051050496> does it work in mpv-git?

nope, tried with mpv-git and ffmpeg-git both, same issue.

@clever cedar stock mpv or a frontend?

clever cedar Mar 12, 2025, 7:09 PM

#

worthy nymph <@532113204051050496> stock mpv or a frontend?

both stock mpv invoked from a terminal and via other apps that use mpv behind the scenes (which is where I first encountered the issue)

@clever cedar can you link the "mp3"

worthy nymph <@532113204051050496> can you link the "mp3"

(it's from a flashcard about pitch accent, if you're wondering)

#

the mpv package hasn't been updated since 2024-11-30, so I guess the trouble is figuring out exactly which dependency is causing the issue...

hmm. I guess there's two broad possibilities:

it's a pipewire/pipewire-pulse/alsamixer/etc. configuration issue of some kind.
need to figure out how to get backtraces if it's an issue with a dependency mpv is calling.

make a issue https://gitlab.archlinux.org/archlinux/packaging/packages/mpv/-/issues

#

it's a pipewire bug and it was already fixed, gonna wait for update now... (https://github.com/mpv-player/mpv/issues/16028)
for now as a workaround run mpv with different audio output backend (e.g. --ao=alsa for ALSA)

segmentation fault when playing certain .mp3 files, pipewire error ...

ah thank you

I just stumbled upon this git issue myself and came back to write here

I will mark the thread as solved
