AVIF support for KImageFormats just landed

Thanks to Daniel Novomesk√Ĺ we will have support for AVIF images in KImageFormats starting in the next release.


We have (and by we I mean him) also added the avif code to be fuzzed under oss-fuzz so we'll be helping the upstream libavif/libaom to find potential memory issues in their code.

CMake: Use new style imported targets to link libraries

 What does that mean?


It means this https://invent.kde.org/graphics/okular/-/commit/3129b642f996589f1c7fcee513741e1993924241


That is, you add JPEG::JPEG to target_link_libraries, and that's it, no need to add the includes, the compile_definitions and whatnot.

 

This has multiple advantages to the old mode:

  • You can't misspell it, since these are actual things cmake knows about not strings so if you write something like JPEG::JPG it will fail at cmake stage
  • You won't forget to add the include (most of us did at some point) because you don't need to :)
  • The include path is just for that particular target (the old method added it to "everyone")
  • It's basically less lines so it's harder to do wrong

 

To know if you can use that you'll need to use the cmake help, for example the imported target is described at https://cmake.org/cmake/help/latest/module/FindJPEG.html


Now we don't probably depend on cmake 3.19, do we? So we need to make sure the cmake we say we support has that, so use the combo on the top of that page to go and find which version introduced it, for JPEG we can see it was cmake 3.12

Planned obsolence for Android phones

Four years ago I bought a OnePlus 2 for 319€, nowdays it still is good hardware, it's better or as good as most of the mid to low end phones in the market.

 

But it has a big-ish problem, it is stuck on Android 6, which not only is old and probably full of security holes, it is starting to not be supported by some apps.


Solution: LineageOS.


It provides Android 10 for my phone and works flawlessly (from what i can see, only been using it for 4 days), so the fact that "some randos" (with all my love, I'm a rando) can make it work, means that the manufacturer could have if they wanted, they just chose not to.


It's really sad because if i wasn't a geek that knew how to put LineageOS on the device i would have probably ended up buying a new phone, making the world be fill with more junk.


Let's hope the more open devices like the PinePhone KDE Community Edition put an end to this :)
