Cannot reproduce. I can reproduce this in fedora rawhide and opensuse krypton, recording either fullscreen or window has this problem, rectangular region seems to work. I though this could be a nvidia problem but it happens on proprietary and free nvidia drivers and also on a VM I can reproduce this. Oddly, I can record the screen without freezing if I start the screen recording after doing a different type of recording. Created attachment 164143 [details]
Noah's backtrace
Based in the fact that no Spectacle C++ files are mentioned in the backtrace and I do see KPipeWire C++ files, I think this might be a KPipeWire bug.
It didn't used to happen, but now I'm sometimes getting this bug with all recording modes. I think it's the same bug as this because the backtraces look the same. I also encounter this issue with Spectacle's full-screen recording that began with Fedora Kinoite Rawhide.20231224.n.0 and persists in later versions. This problem only occurs when attempting to record in full-screen mode. Packages Downgraded from Rawhide.20231224.n.0 to Rawhide.20231223.n.0: libssh 0.10.6-2.fc40 -> 0.10.6-1.fc40 libssh-config 0.10.6-2.fc40 -> 0.10.6-1.fc40 nspr 4.35.0-17.fc40 -> 4.35.0-16.fc40 nss 3.96.1-1.fc40 -> 3.95.0-1.fc40 nss-softokn 3.96.1-1.fc40 -> 3.95.0-1.fc40 nss-softokn-freebl 3.96.1-1.fc40 -> 3.95.0-1.fc40 nss-sysinit 3.96.1-1.fc40 -> 3.95.0-1.fc40 nss-util 3.96.1-1.fc40 -> 3.95.0-1.fc40 Is this a correct repro of this?: https://www.youtube.com/watch?v=kT56-uTEqwE The trick is that you need to record a screen twice in a row. I have replicated this with Rectangular Region and Full Screen. Or are these two different freezes? I have this problem and it affects all types of recording - full screen, window, region. I have spectacle set up to record h264 videos in the .mp4 container. When recording is stopped, these entries appear in its log and it freezes completely: spectacle[461481]: *** impl_ext_end_proxy called from wrong context, check thread and locking: Not in loop spectacle[461481]: *** pw_stream_destroy called from wrong context, check thread and locking: Not in loop The recording can be seen in /tmp/Spectacle.xxxxxx/Screencast_yymmdd_hhmmss.mp4 and it plays back fine with no errors/warnings at all in the mpv output. It looks as if it's saved correctly, but Spectacle hangs when trying to stop the Pipewire screen capture and it doesn't get to move the screencast from the temp dir to the target. I forgot to mention my versions: * Spectacle 24.05.2 * KDE Frameworks 6.3.0 * KPipeWire 6.1.2 * Qt 6.7.2 * Pipewire 1.2.0 (In reply to Kacper Koniuszy from comment #10) > * Pipewire 1.2.0 Ah, it's bug 489434 and a patch is mentioned there. Sorry for sending three comments in a row. Anyways, if you stumbled upon this bug report, you might want to check if you have pipewire 1.2.0 – if so, it's probably that bug and not this one, the symptoms are basically the same though. I'll add it to "See Also". After weeks of working spectacle I now run into this problem too. Not sure if this is helpful, but the only information I got: spectacle: 24.05.2 pipewire: 1.2.0 libKPipeWire6: 6.1.2 > [libvpx-vp9 @ 0x7ffec44c5180] v1.14.1 > [New Thread 0x7ffebd6006c0 (LWP 415233)] > [New Thread 0x7ffebcc006c0 (LWP 415234)] > Downloading separate debug info for /usr/lib64/qt6/plugins/kf6/kwindowsystem/KF6WindowSystemKWaylandPlugin.so > kpipewire_dmabuf_logging: eglChooseConfig returned this many configs: 1 > [New Thread 0x7ffea7e006c0 (LWP 415260)] > [New Thread 0x7ffea74006c0 (LWP 415261)] > [New Thread 0x7ffea6a006c0 (LWP 415262)] > Downloading separate debug info for /lib64/libGL.so.1 > [Thread 0x7ffebcc006c0 (LWP 415234) exited] > [Thread 0x7ffebd6006c0 (LWP 415233) exited] > [many threads exit] *** pw_stream_destroy called from wrong context, check thread and locking: Not in loop *** impl_ext_end_proxy called from wrong context, check thread and locking: Not in loop > [Thread 0x7fff67e006c0 (LWP 414902) exited] > [Thread 0x7fff59c006c0 (LWP 414910) exited] |
