Rust wrapper for libvda. This library is used to enable communication with Chrome‘s GPU process to perform hardware accelerated decoding and encoding. It is currently in development to be used by crosvm’s virtio-video device.
You can build and run unittests with emerge in chroot.
# Build (chroot)$ emerge-{BOARD} dev-rust/libvda # Unit tests (chroot)$ FEATURES=test emerge-{BOARD} dev-rust/libvda
You can also execute cargo
directly for faster build and tests. This would be useful when you are developing this crate. Since this crate depends on libvda.so, you need to install it to host environment first.
# Change host's linker to gold since host environment's default linker GNU ld # fails to link libraries. (chroot)$ sudo binutils-config --linker ld.gold (chroot)$ sudo emerge chromeos-base/libvda # Install libvda.so to host. # Build (chroot)$ cargo build # Unit tests (chroot)$ cargo test
