Vimix dont start Ubuntu 22.04.2 LTS Gnome 42.5. Hi I run vimix on my laptops (dell inspiron and HP) without problems. Since some update early from this year. Vimix not starting... Error from terminal:

igor@dv9850ea:~$ vimix /snap/vimix/1060/usr/bin/vimix: symbol lookup error: /snap/vimix/1060/gnome-platform/usr/lib/x86_64-linux-gnu/libgtk-3.so.0: undefined symbol: pango_font_family_get_face

Have any idea what is wrong? thanx i

Thanks for the issue report. I replicated and should be able to fix it.

Meanwhile, maybe you can install the Flatpak ?

Hi, I'm having the same issue on Debian Cinnamon,

/snap/vimix/1069/usr/bin/vimix: symbol lookup error: /snap/vimix/1069/gnome-platform/usr/lib/x86_64-linux-gnu/libgtk-3.so.0: undefined symbol: pango_font_family_get_face

How do I install the flatpack?

Edit:

Figured it out and vimix is running again! Thank you so much!

I just released a new Snap (with Core22 and Gnome 42) : please let me know if it worked.

Thanks for pointing this out! The new Core22 didn't satisfy dependencies for the required libav (which has all decoders) and didn't show any warning when snapping... maybe a bug report for snapcraft :)

Anyways, should be in order now (updated snap: uninstall and re-install vimix)

It looks like vaapi decoder (hardware accelerated on GPU, the gstreamer module) is failing. To read this video, you can disable hardware decoding in Settings.

From there, you can disable the hardware decoding for this particular video; this is in the Player menu 'Video':

Once this video is tagged as 'disable' hardware decoding, you can restore the general Settings to enable the hardware decoding.

This is definitely not optimal; I will try to add an option to force this 'disable hardware decoding' on the loading user interface.
