Manual How to install AVIF support in KDE

What is AVIF?

AV1 Image File Format (AVIF) is an advanced image format specified by Alliance for Open Media.

AVIF is technically a picture compressed with AV1 video codec wrapped in ISO Base Media File Format.
AV1 compression provides significantly better efficiency than traditional JPEG. Beside 8bit per channel AVIF allows 10bit and 12bit depth, transparency, color profiles, metadata, animation, compression quality ranging from visually lossless to highly compressed lossy while maintaining decent visual quality at low bitrates.

1) Download

Download Latest Release and extract the content of the zip file:

unzip qt-avif-image-plugin-0.8.5.zip

Recommended: read README.txt

2) Adding MIME type

If you have shared-mime-info 2.0 or newer installed, you may skip this step. AVIF MIME type are installed already.

In order to install mime type image/avif in your system, copy (as root) qt-avif-image-plugin.xml file to /usr/share/mime/packages/ folder and run:

update-mime-database /usr/share/mime

3) Compile Qt Image Plugin

Qt Image Plugin allows Qt and KDE applications to open/save pictures in AVIF format. The plug-in uses libavif internally.
You need Qt5 development packages (for example qtbase5-dev), qmake, you may also need cmake and yasm.

If your system has libavif installed (version 0.8.2 or newer, check for the presence of /usr/include/avif/avif.h), run:

./build_libqavif_dynamic.sh

If you don't have libavif installed, run:

./build_libqavif_static.sh

Alternative way of building using cmake

This alternative requires extra-cmake-modules

mkdir build
cd build
cmake ..
make

Windows builds

MSYS2 platform

Use same steps like building under Linux.

Microsoft Visual Studio + Qt Creator

You need to prepare libaom.a and libavif.a before opening qt-avif-image-plugin_local-libavif.pro in Qt Creator.

Prepare libaom.a

Create folder ext\libavif\ext\aom\build.libavif\ and change to this folder.

Run C:\Qt\Tools\CMake_64\bin\cmake.exe -G "Visual Studio 16 2019" -DCMAKE_BUILD_TYPE=Release -DENABLE_DOCS=0 -DENABLE_EXAMPLES=0 -DENABLE_TESTDATA=0 -DENABLE_TESTS=0 -DENABLE_TOOLS=0 -DCONFIG_PIC=1 ..

cmake should create project files for Visual Studio. Now you can open AOM.sln

Go to Configuration Manager... and change (if necessary) Active solution configuration from Debug to Release.

Build Solution

Copy and rename ext\libavif\ext\aom\build.libavif\Release\aom.lib to ext\libavif\ext\aom\build.libavif\libaom.a

Prepare libavif.a

Create folder ext\libavif\build\ and change to this folder.

Run C:\Qt\Tools\CMake_64\bin\cmake.exe -G "Visual Studio 16 2019" -DCMAKE_BUILD_TYPE=Release -DBUILD_SHARED_LIBS=OFF -DAVIF_CODEC_AOM=ON -DAVIF_LOCAL_AOM=ON ..

cmake should create project files for Visual Studio. Now you can open libavif.sln

Go to Configuration Manager... and change (if necessary) Active solution configuration from Debug to Release.

Build Solution

Copy and rename ext\libavif\build\Release\avif.lib to ext\libavif\build\libavif.a

Open qt-avif-image-plugin_local-libavif.pro in Qt Creator

Build Project qt-avif-image-plugin_local-libavif

Plug-in is ready in plugins\imageformats\qavif.dll

4) Install libqavif.so

Copy libqavif.so to a folder where qt5-image-formats-plugins and/or kimageformats are installed. It could be one of these locations:

• /usr/lib/qt5/plugins/imageformats
• /usr/lib/qt/plugins/imageformats/
• /usr/lib/x86_64-linux-gnu/qt5/plugins/imageformats

5) Associate *.avif with applications

Qt based applications should be able to open AVIF images now.
Example how to associate AVIF file type with gwenview:

6) Enable AVIF thumbnails in dolphin file manager

Copy avif.desktop, avifs.desktop to:
/usr/share/kservices5/qimageioplugins/

Update imagethumbnail.desktop (in /usr/share/kservices5/ ):
Add ;image/avif to the MimeType= list:

AVIF thumbnails in dolphin:

Possible small bug with QImageReader::size

Hi again novomesk. This plugin is one of the most extensively developed I have seen, great work!
I noticed in qView that when opening an AVIF image for the first time, the size is reported as -1, -1. After the first image is opened, the correct size is reported until the program is restarted. Are you able to reproduce this, or does this make sense in your code?

Thank you for your time.

Draft a Release

could you please draft a release (i.e. 0.1)? This also creates a tarball which I can use for the flathub build.

thanks!

Check possibility for decoder/thread reuse

First-off - very cool plugin, works off the bat and I like how well it automatically blends in with the Qt image system.

But I found it to be fairly slow.
I noticed in the debugger, that for every image being loaded, 20 threads get launched and then exit again, which seems to me an unnecessary overhead, that may cost more time than it speeds up.
20 threads is the number of logical CPUs on my PC, so that's a match.

The problem is, that Qt will create and destroy an instance of the image handler for each and every picture loaded.

So I wonder, if it shouldn't be possible to create a single, static instance of the avifDecoder and have it keep the threads throughout runtime.
From the libavif explanation of maxThreads, I can't tell how much the avif decoder will actually benefit from multiple threads, if at all. The main use seems to be to parallelize multiple images, which doesn't happen anyway in this current use-case.

Is dav1d supported through libavif?

I made a windows x32 msvc 2019 build that resulted in a dll of 748kb, but it does not seem to actually work when put in a program.
dav1d takes so much less time to build that I would prefer to use that instead of aom.

How do I get it to work on yac reader windows 11?

I tried everything. Placed the DLLsin 'C:\Program Files\YACReader\imageformats'. Tried with both read only and write DLLs. Still yac says comic not found upon opening CBZs with avif files. Please help.

Building on Windows with CMake

I'm trying to use this plugin in a project that uses CMake. I made some modifications to the CMakeLists.txt files to get it to compile. To build libavif, I used libavif from conan (since the project already uses conan and its CMake integration). So finding the avif target wasn't a problem. The only problem was the use of KDE's extra CMake modules. I disabled the search for them on Windows.

Qt 6 added qt_add_plugin which makes it simple to add plugins. To add the plugin, I only need to do the following:

if (QT_AVIF_IMAGE_PLUGIN_STATIC)
  set(_avif_plugin_type STATIC)
else()
  set(_avif_plugin_type SHARED)
endif()
# this requires Qt >= 6
qt_add_plugin("libqavif${QT_MAJOR_VERSION}" ${_avif_plugin_type} CLASS_NAME "QAVIFPlugin")
target_sources("libqavif${QT_MAJOR_VERSION}" PRIVATE ${libqavif_SOURCES})
target_link_libraries("libqavif${QT_MAJOR_VERSION}" PRIVATE Qt${QT_MAJOR_VERSION}::Gui avif)
set_target_properties("libqavif${QT_MAJOR_VERSION}" PROPERTIES
  AUTOMOC ON
  LIBRARY_OUTPUT_DIRECTORY "${CMAKE_LIBRARY_OUTPUT_DIRECTORY}/imageformats"
)

This code should work for all systems. Qt 5 doesn't have this function, so I'm not sure what the best approach there is.

To use the static version of the plugin in my app, I need to enable QT_AVIF_IMAGE_PLUGIN_STATIC, include the library with add_subdirectory and add "libqavif${QT_MAJOR_VERSION}" in target_link_libraries.

I'll put the diff here, I can open a PR if desired.

Upstream plugin to Qt

Hello,
please upstream your work to Qt, so all Qt users can profit from it. If you've got any questions about the process, build system, etc., feel free to ask. :)

You basically "just" need to insert your plugin here along with the others:
https://code.qt.io/cgit/qt/qtbase.git/tree/src/plugins/imageformats

Draft a Release

I now tested your appveyor built with nomacs and it works like a charm. Currently, I simply download the dll in cmake assuming there will always be one named qavif.dll.

If you could change the status of 0.2.0 from pre-release to release (or draft a new one), I could change the download to the generic releases/latest/qavif.dll.

thanks for contributing!

Loose the restrictions about image size in qjpegxlhandler

Hello,
please increase the size restrictions such as 32768 in qjpegxlhandler. The jpeg xl support much bigger size. Thanks :)
