Crabby Avif 🦀

Avif parser/decoder implementation in Rust.

Feel free to file an issue for any question, suggestion or bug report. Contributions are also welcome, see CONTRIBUTING.

Features

  • Supports dav1d, libgav1 or android mediacodec as the underlying AV1 decoder.
  • C API compatible with libavif
  • ..and more

Build

git clone https://github.com/webmproject/CrabbyAvif.git
# If dav1d system library can be found with pkg-config, this step can be skipped.
cd CrabbyAvif/sys/dav1d-sys
./dav1d.cmd
# If libyuv system library can be found with pkg-config, this step can be skipped.
cd ../libyuv-sys
./libyuv.cmd
cd ../..
cargo build

Tests

cargo test -- --skip test_conformance

Conformance Tests

git clone https://github.com/AOMediaCodec/av1-avif.git external/av1-avif
git clone https://github.com/AOMediaCodec/libavif.git external/libavif
cd external/libavif/ext
./dav1d.cmd
cd ..
cmake -S . -B build -DAVIF_CODEC_DAV1D=LOCAL -DAVIF_LIBYUV=OFF -DAVIF_BUILD_APPS=ON
cmake --build build --parallel -t avifdec
cd ../..
cargo test -- test_conformance

If you already have the av1-avif repository checked out and the avifdec binary available, you can point to those by setting the following environment variables:

sh CRABBYAVIF_CONFORMANCE_TEST_DATA_DIR=<path> CRABBYAVIF_CONFORMANCE_TEST_AVIFDEC=<avifdec_binary> cargo test -- test_conformance

C API Tests

# Build google test
cd external
./googletest.cmd
cd ..
# Build the library with C API enabled
cargo build --features capi --release
# Build and run the C/C++ Tests
mkdir c_build
cd c_build
cmake ../c_api_tests/
make
make test

Android Tests

The decoder tests can be run on Android using dinghy.

# One time set up
cargo install cargo-dinghy
# Set path to NDK
export ANDROID_NDK_HOME=<path_to_ndk>
# Install rust toolchain for target
rustup target add aarch64-linux-android
# End of One time set up
# Make sure the device/emulator is available via adb.
cargo dinghy -d android test --no-default-features --features android_mediacodec,libyuv --target aarch64-linux-android --test decoder_tests
