Flatpak can't access gstreamer plugin

[Artim96]

I just installed 0.10.1 from flathub, yet it can't access the camera due to these errors:

flatpak run vn.hoabinh.quan.CoBang

(gst-plugin-scanner:6): GStreamer-WARNING **: 18:13:33.395: Failed to load plugin '/app/lib/gstreamer-1.0/libgstva.so': /app/lib/libudev.so.1: version `LIBUDEV_247' not found (required by /usr/lib/x86_64-linux-gnu/libgudev-1.0.so.0)

(__main__.py:3): cobang-CRITICAL **: 18:13:33.736: Failed to create Gst Pipeline. Error: gst_parse_error: no element "gtksink" (1)

Reading from an image works, but it doesn't show anything in "results", only in the raw results.

Running on Debian testing with Gnome 44 and on Wayland.

Same issue here on Linux Mint 21.2 Cinnamon Standard installation. It worked some time ago without problem, don't know when it stopped working.

Sorry for slow progress. Since v0.10.1, CoBang is broken with FlatHub. I'm trying to fix. It is difficult because it can only reproducible after releasing to FlatHub. It is Ok in development, though.

@Artim96 , @Isolator70 , @hubertbanas It has been fixed in v0.10.3 and waiting to be listed in FlatHub. You can try the testing build as in https://github.com/flathub/vn.hoabinh.quan.CoBang/pull/9#issuecomment-1869690339

I uninstalled the regular version before installing it via that command you linked, though didn't remove user data with it.
