segmentation fault when trying to loop-file #8353

Closed indeedwatson closed 3 years ago

indeedwatson commented 3 years ago

Important Information

Provide following Information:

In my input.conf I have


r cycle_values loop-file inf no
R cycle_values loop-playlist inf no # repeat whole playlist

Until recently, it did what it was supposed to, repeat the video once it finishes.

But now it makes mpv crash with segmentation fault. I've commented out all of my config except for those two lines and the issue persists.

FYI, your log shows that you're actually running mpv 0.33.0-18-ga74b6619f2 (which is latest master as of this writing). What you posted in the issue template is just the last time the AUR build script was updated.

Your log also shows you have some scripts/plugins loaded. Did you also try disabling those when you commented out your config? Try running with --no-config to actually disable everything. You can use use the default keybinding Shift + L to toggle loop-file like your r does, or use --input-conf to point to a file with the two input lines you posted.

If I had to guess, I'm suspicious of /home/yama/.config/mpv/scripts/mpris.so. It's a binary plugin and MPRIS has a LoopStatus property.

In any case, I can't reproduce with the same version on Arch, so if it's not one of your scripts/plugins, you'll probably have to bisect and/or run in a debugger. If you don't know how, I or someone else can help, but I'm pretty sure it's mpris or another plugin, so please check that first.

A backtrace could be useful. run gdb mpv then type run videofilehere and then once it segfaults do a bt full and show us the output.

@qmega You're right, it's mpris. Thank you for the pointer.

Luckily mpris is not a very crucial plugin for me so I'll remove it, but it would be nice to fix this.

then you should report is upstream.
