Frequent crashes in GTK CSS code when run as regular user

Filed https://gitlab.gnome.org/GNOME/gtk/-/issues/6611 .

it's kinda starting to look a lot like this isn't a guvcview issue, anyway. will probably move it to gtk or mutter or something soon.

qt5 with SDL does not solve the crash, and we get a pretty weird backtrace that goes qt5->glib->gdk->gtk3: Stack trace of thread 266293: #0 0x0000000200400310 n/a (n/a + 0x0) #1 0x00007fa81573c979 gtk_css_node_real_update_style (libgtk-3.so.0 + 0x13c979) #2 0x00007fa8157398eb gtk_css_node_ensure_style.part.0 (libgtk-3.so.0 + 0x1398eb) #3 0x00007fa815739b88 gtk_css_node_validate_internal.part.0 (libgtk-3.so.0 + 0x139b88) #4 0x00007fa815739bdb gtk_css_node_validate_internal.part.0 (libgtk-3.so.0 +...

OK, so, found out a couple of things: Building with SFML does indeed seem to avoid the problem. Tried running an SFML build twice and letting it run for a while, it didn't crash. The crash seems to be Wayland-specific. When running on X.org, the crash doesn't happen. This might explain why folks have had trouble reproducing it outside of Fedora, I guess. Edit: looks like it may even be GNOME-on-Wayland specific; Neal Gompa says it doesn't crash on KDE-on-Wayland. Didn't try qt UI-on-SDL yet, will...

OK, if it will help with triaging I'll try both and report back. thanks!

If the problem is in sdl2, then using the qt interface shouldn't make any difference. The crash should happen any way. If the problem is in the gtk interface, then yes, using the qt interface should produce a different output
-
"I don't think fedora default theme is the same as gtk default (Adwaita)." It is. We use pretty much all upstream GNOME defaults, these days. "Have you tried with sfml render instead of sdl2?" Not yet, I can try that if you think it may help. Switching to the qt5 backend will obviously produce different results, but...it feels like a weird way to resolve the gtk backend crashing when it shouldn't. :D
-
I don't think fedora default theme is the same as gtk default (Adwaita). In any case guvcview doesn't use any of the gtk css stuff directly. For what I can see from your backtrace, there seems to be some calls to sdl decorate border, I'm not sure about sdl2 internals, but if you running gnome, maybe window decorations use gtk css. Have you tried with sfml render instead of sdl2?
-
This is with default theme. I reproduced this on a completely clean fresh boot of Fedora (40). I agree the different result with root points to some kind of permission situation, but the app still should not just crash, and I was hoping as the author you might have some kind of idea what different permissions might cause the app to go down different paths early in startup, so we could try and isolate exactly where the divergence is. I would like to try giving the regular user one additional permission...
-
Hi, have you tried with the qt interface : --disable-gtk3 --enable-qt5 You can also enable the sfml render: --enable-sfml and then: guvcview --render=sfml As for the GTK interface, I really can't reproduce the problem in Arch. Did you tried changing your gtk theme? If it works under root then it's most likely a permission issue. Just try with a default theme like Adwaita or installing a local theme. Regards,

jpeg_decoder.c and uvc_h264.c are missing include of libavutil/imgutils.h for av_image_get_buffer_size
-
Morpher posted a comment on ticket #48
Also, Guvcview creates large video files which could be reduced by allowing the specification of H264 attributes "crf" and "gop_size". In my case adding some command line parameters which set internal global variables would be sufficient. I am a coder and could do the work if that helps.

Add binary fx filter

Hi, This will only work for gtk3, you also need to change MainWindow::render_fx_filter_changed(int state) in gui_qt5_callbacks.cpp so that the filter is available in the qt5 interface. Otherwise it wont even build with configure --enable-qt5

There is a very useful little program called sViacam which runs on Windows and appears not to have been updated since 2012 Could you please consider adding similar functionality to guvcview ? … it would obviously be even better on the RasPi with its GPIO

Hello, Is there a way to configure guvcview so that it can record the audio from another device (desktop audio, jack, etc) rather than just the defaut built in microphone? Thanks.

Hi everyone, I'm currently using guvcview 2.0.6 I was hoping to get some help as I'm getting intermittent crashes when capturing video. For context I work in a Neuroscience motion vision lab and were using guvcview to capture footage from a PlayStation camera running at 100 fps while running a stimulation in Matlab, for automation sake I'm opening guvcview using a bash command that doesn't open a terminal window, as Matlab pauses if it opens a terminal. I'm then sending a kill signal USR1 to guvcview...

hi, To build from source you should follow the readme.md file. To create the configure script just run the bootstrap script first. Also you should be able to get precompiled deb files from my ppa ppa:pj-assis/ppa Regards, Paulo

Hello I use guvcview to adjust my webcam settings. I typically run this on logging into my desktop environment guvcview -p Webcam-Profile.gpfl -z Is there any way to automatically quit quvcview after running the control panel? The -q doesn't work and I think is geared towards users who use it to capture video.
