SUMMARY When I try to start mpv with any mp4 movie happens crash. Example mpv my_movie.mp4 [ffmpeg/demuxer] mov,mp4,m4a,3gp,3g2,mj2: Referenced QT chapter track not found (+) Video --vid=1 (*) (h264 1920x1036 24.000fps) (+) Audio --aid=1 (*) (aac 6ch 48000Hz) (+) Subs --sid=1 'my_movie.srt' (subrip) (external) Segmentation fault (core dumped) Please notice that in Arch Linux mpv works correctly with the same movie. STEPS TO REPRODUCE 1. Try to play any mp4 movie 2. 3. OBSERVED RESULT Segmentation fault (core dumped) EXPECTED RESULT mpv should play movie, like it happens couple weeks ago SOFTWARE/OS VERSIONS Linux/KDE Plasma: KDE Plasma Version: 5.3.80 KDE Frameworks Version: 6.14.0 Qt Version: 6.8.3 ADDITIONAL INFORMATION mpv --version mpv 0.37.0 Copyright © 2000-2023 mpv/MPlayer/mplayer2 projects libplacebo version: v6.338.2 FFmpeg version: 6.1.1-3ubuntu5 FFmpeg library versions: libavutil 58.29.100 libavcodec 60.31.102 libavformat 60.16.100 libswscale 7.5.100 libavfilter 9.12.100 libswresample 4.12.100
Sorry, is there any chance that someone will look at it and fix? Just kindly remind that smplayer stopped work long time ago, and recently (couple weeks ago) also mpv.
Below please find a bit more details: In case of: (h264 1920x960 24.000fps), (hevc 1920x800 24.000fps) happens segmentation fault In case of: (mpeg4 720x384 24.000fps) works well Produced core is between 13 - 20MB (compressed - zst format). If this will help I can attach. BTW. mplayer (1.5+svn38446-1build5) is able to play all of above.
To me it works if I start mpv with no hardware acceleration, with --hwdec=no parameter.
Please report this to mpv
(In reply to Nicolas Fella from comment #4) > Please report this to mpv Hmm, I'm not sure this is issue in mpv side. Please notice that the same version was working for me couple months ago before I reported this issue. I checked logs and found that version 0.37 was first time installed at Dec, 2nd 2023: $ apt changelog mpv </cut> mpv (0.37.0-1) unstable; urgency=medium * New upstream version 0.37.0 * debian/patches: Refresh patches * debian/libmpv2.symbols: Add new symbol * debian/docs: Update list of installed documentation * debian/control: - Add libcdio-dev to BDs - Bump required libplacebo-dev BD - Switch to pkgconf -- Sebastian Ramacher <sramacher@debian.org> Sat, 02 Dec 2023 12:30:21 +0100 </cut> Today we have in Neon is still the same version. For sure mpv was working for me at 2024 year, but stopped at the first half of 2025. I'm not sure what changed in between that time. <cut> $ apt show mpv Package: mpv Version: 0.37.0-1ubuntu4 </cut> Second thing Why mpv is not updated to the latest version? Only is installed 2 years old version? I wonder what is the problem with update? In Arch Linux we can find ver. 0.40, what was released at March, 2025.
(In reply to Giva Barreto from comment #3) > To me it works if I start mpv with no hardware acceleration, with --hwdec=no > parameter. Thanks for tip. Also for me works. The thing is why it stopped work without this parameter in this year, whereas the version didn't change (and also I didn't change hardware only I made updates of Neon) BTW. I have integrated Intel GPU: "TigerLake-LP GT2 [Iris Xe Graphics] (rev 01)"
