The log looks like a gpu driver issue. Could you hover over the X icon and tell me the tooltip log?

Okay, this is interesting. I always face these and takes me ages to solve.

I can't get snapcraft to work right now, so feel free to try yourself by adding the followiing to the snap config

• libgstreamer1.0-dev
• libgstreamer-plugins-base1.0-dev
• libgstreamer-plugins-good1.0-dev

[GeopJr]

Thanks for the report! The last snap update includes gstreamer & co.

I'm still getting this issue in latest version :(

I feel you may need to add gstreamer1.0-plugins-bad to the stage packages (and make gstreamer to load them)?

Honestly, my hands are tied. I can take another look but the snap is a black box to me at this point. It's here: https://github.com/GeopJr/tuba-snap/blob/main/snapcraft.yaml

Note that this issue is from a year ago, and since then we switched to libclapper by default from GtkVideo. I'm positive that at the time of this issue this was fixed.

(fwiw, webkit doesn't work either, even though I'm positive that I followed the way other snaps added do it)

webkit seems to work properly to me (if you mean the embedded browser), but I did not tried videos there

I can take another look but the snap is a black box to me at this point.

Technically it's just about installing the gstreamer plugins packages (bad and even ugly if you want) and set GST_PLUGIN_PATH=$SNAP/path-of-those-plugins:$GST_PLUGIN_PATH

the snap is a black box to me at this point

Unfortunately, after adding the stage-packages, setting the env vars and verifying the plugins are there using --shell, I reached another roadblock 🤷

/snap/tuba/x1/usr/bin/dev.geopjr.Tuba: symbol lookup error: /snap/tuba/x1/gnome-platform/usr/lib/x86_64-linux-gnu/libharfbuzz-subset.so.0: undefined symbol: hb_free

I'll continue tomorrow and maybe ask on the forum, but sadly it's still a black box for me.

[3v1n0]

Probably you can filter out those dependencies that it brings in (use prime: [-usr/lib/*/libharfbuzz*]) since those should be provided by the gnome extension anyway
