[Cocoa] Add an open source AVIF decoder to WebKit (libavif and dav1d)
https://bugs.webkit.org/show_bug.cgi?id=246598 rdar://101226446 Reviewed by Elliott Williams. The purpose of this patch is to bring AVIF image decoding to older versions of macOS. AVIF images are natively supported in macOS in macOS Ventura, but WebKit ships to versions of macOS older than that. If we want AVIF images to be supported on those OSes, WebKit has to include an image decoder. The decoder this patch adds can be deleted as soon as all macOS versions that WebKit targets support AVIF. This is being included as part of WebKit, rather than a separate project/repo, simply for expedience. WebCore is the only customer of this image decoder; other Cocoa software that wants to use AVIF should use the system decoder. WebKit is special here because we ship to old OSes. The open source image decoder consists of 2 libraries: libavif, which parses the file, and dav1d, which is a software AV1 decoder. AVIF images use the AV1 codec internally. The version of libavif contained in this patch came from tag v0.11.0 in this repository: https://github.com/AOMediaCodec/libavif.git. This tag corresponds to commit 3c48152f9a22bd9ae827c9cbaf7f4db3e6387d48. The contents of the repository are completely unmodified. I had to check in some generated files; the process I used to generate them is: % mkdir builddir % cd builddir % xcrun cmake -DAVIF_CODEC_DAV1D=yes -DDAV1D_LIBRARY=/Users/mmaxfield/src/dav1d/builddir/src/libdav1d.a -DDAV1D_INCLUDE_DIR=/Users/mmaxfield/src/dav1d/builddir/include -DBUILD_SHARED_LIBS=false .. % xcrun cmake --build . The version of dav1d contained in this patch came from tag 1.0.0 in this repository: https://code.videolan.org/videolan/dav1d.git. This tag corresponds to commit 99172b11470776177939c3d2bc366fe8d904eab7. The contents of the repository are completely unmodified. I had to check in some generated files; the process I used to generate them is: % meson setup -Denable_asm=false -Ddefault_library=static builddir % cd builddir % ninja % cp ../include/dav1d/*.h include/dav1d/ I created Xcode projects for both of these libraries. For dav1d, I did not include any of the assembly language files in the compilation target; this will aid us being able to build for both Intel macs and Apple Silicon macs. The goal of this project is format support on old OSes; it's okay if the implementation isn't super-assembly-language-fast. I had to create Xcode projects for these libraries, rather than just adding new Xcode targets, because there are filename colisions between these libraries and PAL. Specifically, there is a config.h in dav1d and in PAL. Headermaps do not allow for the same project to contain the duplicate filenames, so I created the following project structure: WebCore.xcodeproj | +--> PAL.xcodeproj | +--> libavif.xcodeproj | +--> dav1d.xcodeproj These projects are parents of each other, rather than siblings, so we can set up correct dependency chains / include paths from depended-on projects to depending projects. The projects are set up to create static libraries. I copied the projects' xcconfig files from PAL's xcconfig files. I'm intentionally setting up these projects to compile on all OSes, not just old versions of macOS. The reason for this is just conditional compilation is complicated to set up, and the full build for these libraries takes literally 3 seconds on my machine. The cost is not worth the benefit. However, I am avoiding linking with this library on older OSes, to avoid the potential binary size increase. Both of these libraries are placed in their own directories, kept separate from Apple proprietary code, and all original headers, copyright notices and license information within their source code are retained. * Source/WebCore/PAL/PAL.xcodeproj/project.pbxproj: * Source/WebCore/PAL/libavif/CHANGELOG.md: Added. * Source/WebCore/PAL/libavif/CMakeLists.txt: Added. * Source/WebCore/PAL/libavif/Configurations/Base.xcconfig: Added. * Source/WebCore/PAL/libavif/Configurations/DebugRelease.xcconfig: Added. * Source/WebCore/PAL/libavif/Configurations/libavif.xcconfig: Added. * Source/WebCore/PAL/libavif/LICENSE: Added. * Source/WebCore/PAL/libavif/README.md: Added. * Source/WebCore/PAL/libavif/android_jni/.gitignore: Added. * Source/WebCore/PAL/libavif/android_jni/README.md: Added. * Source/WebCore/PAL/libavif/android_jni/avifandroidjni/.gitignore: Added. * Source/WebCore/PAL/libavif/android_jni/avifandroidjni/build.gradle: Added. * Source/WebCore/PAL/libavif/android_jni/avifandroidjni/proguard-rules.pro: Added. * Source/WebCore/PAL/libavif/android_jni/avifandroidjni/src/main/AndroidManifest.xml: Added. * Source/WebCore/PAL/libavif/android_jni/avifandroidjni/src/main/java/org/aomedia/avif/android/AvifDecoder.java: Added.
