Dev appimage version is not able to play well all videos, all the time

[kelson42]

Steps to reproduce:

• Download recent ZIM with videos https://library.kiwix.org/#lang=eng&q=ted+connect
• Download recent appimage https://download.kiwix.org/nightly/2024-09-29/kiwix-desktop_x86_64_2024-09-29.appimage
• Play the first video top left (just click on play button and nothing else)
• I get systematically this

It should work actually, my dev version compiled locally (with a slightly recenter version of Qt) works!

I confirm the issue. Old videos play fine. New videos don't. The same problem is present when building and running kiwix-desktop on Ubuntu 20.04 focal (which is the platform where we create the appimage). So it is an issue with an old version of Qt being used. What should we do about it?

@veloman-yunkan What are the perspectives of building against a more recent version of Qt in appimages.

@kelson42 Do you mean still building on Ubuntu 20.04 focal but using a more recent version of Qt? Or building on a more recent distribution of Ubuntu? The later solution is likely to make the appimage unusable on older distributions.

@veloman-yunkan If we can build with recenter version on focal, then this is great, otherwise I think we should move to 22.04 if this helps to fix that problem.

If we choose the second path, we can also decide to release 2.4.0 with current solution, and fix this issue in 2.5.0

[kelson42]

Decision has been made to compile appimage on Ubuntu 22.04.

[veloman-yunkan]

Appimage cannot be built on Ubuntu 22.04 using the same process, as linuxdeployqt refuses to work on such a new OS. I will try to find out if the problem can be circumvented by switching from linuxdeployqt to linuxdeploy + linuxdeploy-plugin-qt.
