I think in arch libdecor doesn't force the gtk3 plugin, so SDL in gnome ends up using the default cairo backend.

-
this is because mutter doesn't implement xdg-decorations and forces csd (client side decorations), this seems like a lost battle. All wayland compositors, implement ssd (server side decorations) with the exception of gnome and enlighthment.

This can't be the issue. Building guvcview with Qt and disabling Gtk also causes the same crash (according to your tests). Disabling Gtk makes sure guvcview isn't even linked against Gtk. Guvcview only uses Gtk in the main thread. The render thread uses SDL or SFML. I don't know any distribution in that SDL has a direct dependency on Gtk. This just doesn't make any sense. SDL is supposed to be system independent. libdecor is NOT a gtk lib, although it has a optional Gtk pluggin (https://gitlab.freedesktop.org/libdecor/libdecor)...
-
Checking SDL API I found that libdecor is used over xdg-shell when xdg-decoration protocol is unavailable. So if xdg-decoration is available native decorations are used instead. In Arch both SDL and libdecor are build with a dependency on wayland-protocols package that includes xdg-decoration, so in arch at least, both SDL and libdecor use native wayland window decorations instead of the Gtk3 pluggin.
-
libdecor can be disabled programmatically : https://wiki.libsdl.org/SDL2/SDL_HINT_VIDEO_WAYLAND_ALLOW_LIBDECOR just need to add SDL_SetHint("SDL_HINT_VIDEO_WAYLAND_ALLOW_LIBDECOR", "0"); to render_sdl2.c just after SDL_SetHint("SDL_HINT_RENDER_SCALE_QUALITY", "1"); around line 84

Hi, I've been running guvcview in wayland with the sdl backend for 2+ years (in Arch) without any issues. The gui and the render run in different threads, this is how guvcview is designed. I've tested in gnome, plasma and sway and never had any issues. Could this be related to the way sdl is build?

fix libs version
-
Also needs QT support for merging, otherwise it will loose consistency between GTK and QT interfaces. Since I don't have this camera to test, I can't add support for the QT interface myself.
-
fix the guvcview with mjpeg when I use high resolution camera to preview
-
add corrected fix to master with commit [9b143fe]

-
update GL linking
-
add -lGL to gview_render and guvcview if SFML is used
-
make -lGL option PUBLIC
-
in some distros GL is not linked for gview_render, force it with -lGL
-
change build system: move from autoconf to cmake
-
fix x265 encoder defaults
-
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). 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?
-
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,
-
always link guvcview with -lGl if sfml build is enabled; bump guvcview and libraries verion
-

Make guvicview skips device files for metadata.
-
apply Kentaro Fukushi patch: Make guvicview skips device files for metadata.
-
fix printf warning
-
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
-
Wrong COPYING file in the sources

fix deprecated avcodec calls
-
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
-
Also you should set --verbosity=4 this will output a lot of debug info that can be used to identify the issue.
-
No. What broke 2.0.6 was libavencoder. It was just a little change. AVPacket now sets the audio channels to 0, regardless of what is set on the codec context. So I just needed to reset the channels after libavcodec set the AVPacket defaults. The problem was that the encoding failed with a generic error and without outputing any debug info, so I had to debug both guvcview and libavcoded. Portaudio and pulseaudio have been working without issues for years. Please make sure you clean any older versions...

-
Also make sure you removed the old version completly, including the application libs located in /usr/lib/ (libguv*) or whathever place their installed. It can happen that the old libs are being used instead of the new ones.
-
Make sure to run the bootstrap script first, this will create the configure script.
-
This must be some other issue, I have tested in Manjaro against the latest libavcodec and it is working with all the encoders, also in 2.0.7 if you chose the pcm codec, audio is not even encoded, it's just stored directly to file.
-
it just some small changes to allow static build. Among other tjings, sfml when linked statically needs to link also to libGl

Hi. This was solved in the latest release (2.0.7) Please upgrade to this new version. You can download the source code from the files link. Check the build instrutions in the Readme.md file.
