[SOLVED] Mpv SIGSEGVs after update

After I updated today, my mpv started crashing (SIGSEGV). I couldn't exactly pinpoint the issue, but I suspect it has to do with Nvidia drivers. VLC is working fine. I've discovered that if I list available video outputs (mpv --vo=help) and try other than "gpu", that is "xv", "x11" or "sdl", I get a warning about an obsolete VO, but the video is playing.

I couldn't find the issue reported here or elsewhere, so I started this thread. I suppose it will eventually resolve on its own with another update.

Thanks, confirmed Nvidia issue.

I've tried running mpv through gdb to get complete traceback (pasted here), but I can't see anything better there.
I'll be probably unable to investigate it further till the next week and if the next step is building the nvidia package with debug symbols, I might postpone it further.

Re: [SOLVED] Mpv SIGSEGVs after update

Did you update to linux 7.0.2 ? Do you get the same w/ the LTS kernel?

Re: [SOLVED] Mpv SIGSEGVs after update

Yes, the issue occured with the 7.0.2 kernel. I haven't tried the LTS, but after update to 7.0.3 (and nvidia-open 595.71.05-2), the mpv started working again.
Marking as solved.
