Qt 6.3.0 Player Application

[sildeag]

Using Ubuntu 22.04 and the Qt supplied sample application Player
I get this error Application exit (RuntimeError: index out of bounds) or
Application exit (RuntimeError: indirect call to null). What causes it?

My computer is not capable of OpenGL 3+ and
I use export LIBGL_ALWAYS_SOFTWARE=1 (I am wondering if this setting is somehow being overridden running Player from Qt Creator 7.0.0)

I am using emsdk version 3.0.0 which is consistent with Qt 6.3.0
Application output:
10:48:24: Checking available ports... 10:48:24: Found 1001 free ports. 10:48:24: Starting /usr/bin/python3 /home/me/emsdk/upstream/emscripten/emrun.py --browser firefox --port 30000 --no_emrun_detect --serve_after_close /home/me/Qt/Examples/Qt-6.3.0/multimediawidgets/player/player.html... Gtk-Message: 10:48:27.591: Failed to load module "xapp-gtk3-module" Gtk-Message: 10:48:27.988: Failed to load module "canberra-gtk-module" Gtk-Message: 10:48:27.995: Failed to load module "canberra-gtk-module"

The above Gtk-Message seems irrelevant but also happens when invoking firefox browser from terminal prompt. In Ubuntu 22.04 firefox is installed from snap by default and these messages relate to that.

I would also like to know what is involved in using the latest version of emscripten but walking before running seems like the best approach. Any know what is involved it recompiling Qt6 with emsdk 3.1.8?
